Some of very Easy Science Experiment Projects For School Going Kids

## Simple Physics Experiment

Physics is called as natural philosophy the science of energy and matter and the relations between the two. Physics includes the study of material and energy as related to motions, heat, light, and force. Modern extensions physics has extended to include nuclear physics, particle physics, plasma physics, and cryogenics. Physics is the study of matter that helps to understand elements behave in space and time under the influence of various types of energy and force. The universe operates by explaining concepts in ways that are simple enough for peers to understand.

## 1. Living COLOR:

Objective

While light and preservative colour comes from the primary colours red, green and blue. Use thw wave lights of the primary colours to calculate the preservative colours as well as white light.

Materials

• Wood
• Reflectors
• Paint
• Dimmers
• Wiring
• Red, green, blue lights
• Timer
• Strip diffuser
• Nails
• Calculator
• Pencil
• Camera

Methods

1. Lights, dimmers and wiring assembled into colour.
2. Tests were conducted while blending lights and photos taken.
3. Container was tested by blending primary colours to create additive colours and to create white light. A diffuser strip was added for prism distinction.
4. Apply wavelength numbers to the primary colours and tried to predict the addictive colours by calculating averages of two primary colours that could be blended.
5. Predicting the wave light of white light by using a calculation of all three primary colours.

Results

The wavelengths of each of the primary colours in pairs, was able to calculate the wavelength of the primary colours that the colour machine would produce.

## 2.  Egg in a bottle

It shows the relation of temperature and pressure an egg gets sucked into a bottle.

Materials

• Eggs
• Saucepan and stove
• Wide mouth glass drink bottle(We used large egg with the standard bottle but with other bottles you might need smaller eggs)
• Vegetable oil
• Matches
• Strips of paper folded (Length wise)

Experiment

1. Place the eggs in a sauce pan; add enough water so that eggs are covered by about an inch.
2. Let the water boil for 5 minutes, remove the pan from the heat and cover it.  Let it sit for 25 minutes then remove the eggs and dip them in cold water.
3. Use a paper towel to coat the inside edge of the bottle mouth with a little bit of vegetable oil for lubrication.
4. Peel one of the eggs then dip in water and set it with the small end down in the mouth of the glass bottle. It should be slightly larger than the mouth of the bottle.
5. Use a match to light the end of a strip of paper on fire. Lift the egg off the bottle drop the paper inside with the flame down and quickly replace the egg.
6. Watch the egg twist a little in the bottle mouth and then get sucked inside.

Observation

When the egg is heated the proteins and water molecules begin to move faster. When you first set the egg on the bottle the air pressure inside the bottle matched the air pressure outside. The expanding air pushed the egg a side and escaped from the bottle, it is egg vibrating. The fire consumed all the oxygen inside the bottle, the flame went out and the remaining air in the bottle cooled down. Cool sir takes up less space.

## 3. Bending Water

You need:

• Balloon
• Faucet
• Hair

Experiment

1. Blow up the balloon.

3. Turn on the faucet and let a nice stream of water flow.

4. Hold the balloon next to the flow of water.

Conclusion

You’ll see the water actually bend towards the balloon! When you rubbed the balloon on your hair, the balloon wrap bunches of electrons from your hair. The balloon has so many electrons it has a negative electrical charge. This strong charge creates a temporary positive electrical charge in the water flowing from the faucet which causes the water to be attracted to the balloon.

## 4. I have got a crush

You Need:

• Empty 2 litre soda burst bottle with the cap
• Hot tap water
• Freezer

Experiment

1. Turn on the hot water tap and get it to be quite hot. Don’t burn yourself but the hotter the better.

2. Fill the bottle about 1/4 full with the hot tap water.

3. Swirl and shake the bottle.

4. Pour out the water and put the cap on the bottle as fast as possible.

5. Take the bottle and stick it in the freezer.

6. Let it sit there for at least 30 minutes. Feel free to let it sit there overnight.

7. Take it out of the freezer and take a look at it. You should notice that the bottle will be slightly crushed.

Conclusion

When you spin the hot water around the bottle, you are heating up the air inside the bottle. Hot air has air molecules that are moving fast. They are moving so fast that many of them leave the bottle. When you cap off the bottle you stop air flow from getting back into the bottle. As the air in the bottle cools, the air molecules slow down and push less hard on the sides of the bottle. The colder they get, the less hard they push. This allows the air pressure outside the bottle to push in and eventually squish the sides of the bottle.

## 5. Rise Bubble Rise

You need:

• Bubble making stuff
• Balloon
• Hair

Experiment

2. Rub it on your hair, a shirt, your dog…whatever is handy

3. Now blow some bubbles.

4. As the bubbles float, try to get the balloon over one of the bubbles. You should see the bubble get attracted to the balloon. With a little bit of practice you can get the bubble to float up and follow the balloon.

5. If the bubbles seem to not be attracted to the balloon you may need to rub the balloon on something again. If a bubble popped on the balloon you will want to wash that off.

6. Over time the balloon will lose the static charge you gave it. Also, if your balloon gets wet or foamy it will not hold a charge.

Observation

By rubbing the balloon on your hair, you have given the balloon a negative static charge. The bubble is attracted to the strong charge on the balloon and so it will follow the balloon.

## 6. Colourful flames

You need:

• Candle
• Matches
• Pin or Paper Clip
• Cup with water
• Salt, pepper, flour or any powder like stuff from the kitchen

Experiment

1. Light the candle.

2. Take the salt and pour a bit into a small dish.

3. Wet the tip of the paper clip or pin in the cup of water.

4. Dip the tip of the paper clip or pin into the salt. Try to get some of the salt to stick.

5.  Carefully, stick the tip of the paper clip or pin with the salt on it into the candle

6. Observe the colours coming from the salt.

7. Take the paper clip or pin out of the flame as soon as the colours stop. It will get hot if you leave it in the flame too long.

8. Do the same thing with different stuff.

9. Remember to be careful.

Observation

Different chemicals give off different colours flames when they burn. By trying different stuff on the pin, you may be able to see yellow, green, blue or other colours. Fireworks use this concept. Fireworks will be filled with very explicit chemicals to produce the amazing colours that you see.

## Chemistry Lab Experiments

Any type of experiment whether a large scale scientific research project or performed in a small high school classroom should be performed with the proper safety precautions. When performing any kind of chemistry experiment in the classroom it is essential that students use the right safety equipment and understand the proper procedures to avoid serious injury. Students should always be sure to have permission to do any kind of experiments first while using chemicals.

Certain chemicals when mixed together can cause explosive reactions and can be irritating to the eyes, mouth, and lungs.  If certain chemicals are spilled they can cause skin problems and other serious issues. While performing any kind of experiment with chemicals, eye protection should always be worn.  There is an excellent collection of school experiments are as follows.

## Baking Soda and Vinegar Volcano

The baking soda and vinegar volcano is the kitchen equal of a volcano. It is not a real volcano. The baking soda volcano is also harmless which adds to its application.

Winning Science Fair Volcano Experiment

What You Needed:

• 6 cups flour
• 2 cups salt
• 4 tablespoons cooking oil
• Warm water
• Plastic soda bottle
• Dishwashing detergent
• Food colouring
• Vinegar
• Baking dish or other pan
• 2 T baking soda

Time required for the experiment:  30 minutes

Procedure

Make the cone of the baking soda volcano. Mix 6 cups flour, 2 cups salt, 4 tablespoons cooking oil and 2 cups of water. The resulting mixture should be smooth and firm.

Stand the soda bottle in the baking pan and mould the dough around it into a volcano shape. Don’t cover the hole or drop dough into it.

Fill the bottle most of the way full with warm water and a bit of red food colour (don’t take so long that the water gets cold).

Add 6 drops of detergent to the bottle contents. The detergent helps trap the bubbles produced by the reaction so you get better lava.

Add 2 tablespoons baking soda to the liquid.

Slowly pour vinegar into the bottle.

Tips for best Results:

The cool red lava is a chemical reaction between the baking soda and vinegar.

Carbon dioxide gas is produced which is also present in real volcanoes.

As the carbon dioxide gas is produced, pressure builds up inside the plastic bottle, the gas bubbles out of the ‘volcano’.

Adding a bit of food colouring will result in red-orange lava. Orange seems to work the best. Add some red, yellow, and even purple, for a bright display.

## Elephant Toothpaste Chemistry Demonstration

The elephant toothpaste chemistry demonstration is a dramatic demo which produces plentiful amounts of hot foam that sort of looks like the toothpaste an elephant might use.

Elephant Toothpaste Materials

• 50-100 ml of 30% hydrogen peroxide (H2O2) solution
• Saturated potassium iodide (KI) solution
• Liquid dish washing detergent
• Food colouring
• Splint (optional)

Safety

Wear disposable gloves and safety glasses. Oxygen is evolved in this reaction. The reaction is exothermic, producing a fair amount of heat, so do not lean over the graduated cylinder when the solutions are mixed. Leave your gloves on following the demonstration to aid with cleanup. The solution and foam may be rinsed down the drain with water.

Procedure

Put on gloves and safety glasses. The iodine from the reaction may mark surfaces so you might want to cover

Your work space also needed an open garbage bag or a layer of paper towels.

Pour 50 ml of 30% hydrogen peroxide solution into the graduated cylinder.

Shoot in a little dish washing detergent and spin it around.

You can place 5-10 drops of food coloring along the wall of the cylinder to make the foam resemble striped   toothpaste.

Add 10 ML of potassium iodide solution. Do not slant over the cylinder when you do this, as the reaction is very strong and you may get splashed burned by steam.

You may touch a glowing support to the foam to relight it indicating the presence of oxygen.

Elephant Toothpaste Chemistry

The overall equation for this reaction is:

2 H2O2 (aq) ? 2 H2O (l) + O2 (g)

The decomposition of the hydrogen peroxide into water and oxygen is catalyzed by the iodide ion.

H2O2 (aq) + I-(aq) ? OI-(aq) + H2O (l)

H2O2 (aq) + OI-(aq) ? I-(aq) + H2O (l) + O2 (g)

The dishwashing detergent captures the oxygen as bubbles. Food colouring can colon the foam. The heat from this exothermic reaction is such that the foam may steam. If the demonstration is performed using a plastic bottle you can expect small bend of the bottle from the heat.

What You Needed:

• 5 or more litres of liquid nitrogen
• Gloves and goggles recommended
• Large plastic or stainless steel punch bowl or salad bowl
• 4 cups heavy cream (whipping cream)
• 1-1/2 cups half-and-half
• 1-3/4 cups sugar
• 1 quart mashed fresh strawberries or thawed frozen berries
• Additional half cup of sugar if you are using unsweetened berries
• Wooden spoon
• Wire whisk

## How to Make Liquid Nitrogen Ice Cream

You can use liquid nitrogen to make ice cream much immediately. This recipe is for strawberry ice cream. If you pass over the strawberries you can add a bit of vanilla for vanilla ice cream or some chocolate syrup for chocolate ice cream. This recipe makes a half gallon of strawberry ice cream.

Experiment

First, mix the cream, half-and-half and sugar in the bowl using the cord whisk. Continue mixing until the sugar has dissolved.

If you are making vanilla or chocolate ice cream, whisk in vanilla or chocolate syrup now. Add any other liquid flavouring you might want.

Put on your gloves and goggles. Pour a small amount of liquid nitrogen directly into the bowl with the ice cream ingredients. Continue to stir the ice cream, while slowly adding more liquid nitrogen. As soon as the cream base starts to thicken, add the mashed strawberries. Stir energetically.

When the ice cream becomes too thick for the whisk, switch to the wooden spoon. As it hardens more, remove the spoon and just pour the remaining liquid nitrogen onto the ice cream to fully harden it.

Allow to excess liquid nitrogen to boil off before serving the ice cream.

Tips for best Result:

The mix of whipping cream and half-and-half helps to make a very creamy ice cream with small crystals that freezes quickly.

Don’t touch liquid nitrogen or store it in a closed container.

If the ice cream begins to melt before everyone is served, simply add more liquid nitrogen.

A large plastic mug with a handle is good for pouring the liquid nitrogen. If you use a metal container, be sure to wear gloves.

Mixing attachment is even better than a whisk and wooden spoon.

## Rubber Egg & Chicken Bones

You can make a toy out of just about anything, including a boiled egg. Soak an egg in a common kitchen ingredient, vinegar, to dissolve its shell and make the egg rubbery enough that you can bounce it on the floor like a ball. Soaking chicken bones in vinegar will soften them so that they will become rubbery and flexible.

Rubber Egg Materials Required

• hard-boiled egg
• glass or jar, big enough to hold the egg
• vinegar

Now Turn the Egg into a Bouncy Ball

Place the egg in the glass or jar.

Add enough vinegar to completely cover the egg.

Watch the egg. Little bubbles may come off the egg as the acetic acid in the vinegar attacks the calcium carbonate of the eggshell. Over time the colour of the eggs may change as well.

After 3 days, remove the egg and gently rinse the shell off of the egg with tap water.

You can soak raw eggs in vinegar for 3-4 days, with a slightly different result. The eggs shell will become soft and flexible. You can gently squeeze these eggs but it’s not a great plan to try to bounce them on the floor.

## Make Rubbery Chicken Bones

If you soak chicken bones in vinegar, the vinegar will react with the calcium in the bones and weaken them so that they will become soft and rubbery, as if they had come from a rubber chicken. It is the calcium in your bones that makes them hard and strong.

Materials Needed

• 1/4 cup of baking soda
• 1 cup of vinegar
• bubbles and a bubble wand (you can get this at most toy stores)
• 2 large, clear containers, like a clear plastic or glass bowl
• small clear cup
• bowl
• spoon

Instructions:

Put 1/4 cup baking soda in a clear container.

Then add 1 cup of vinegar.

The mixture of vinegar and baking soda will bubble. It is carbon dioxide.

Blow some bubbles into the container and watch how they float on the carbon dioxide. The bubbles are floating where the carbon dioxide and air meet.

The carbon dioxide stays at the bottom of the bowl because it is denser than the air in the bowl. The bubbles float on top of the carbon dioxide because they are filled with air and the air is less dense than the carbon dioxide.

This will help explain what density means. Pretend that you had two balloons and you filled one with air, and the other one with the same amount of carbon dioxide. The balloons would be the same size, because the gas in them takes up the same amount of space.

But, if you weighed both balloons, the one with the carbon dioxide would be heavier. This means that it’s denser than the balloon with air in it.

If you still don’t understand density, don’t worry. There are lots of people out there who can answer your questions. Talk to your teacher, go to a science museum, visit your local library, or ask your parents.

## Fizzing and foaming

With a few household chemicals you can turn a glass of colored liquid into foam that overflows its container.

For this experiment you will need:

• 15 cm3 (1 tablespoon) of baking soda (sodium bicarbonate)
• 15 cm3 (1 tablespoon) of laundry detergent
• about 180 millilitres (3/4 cup) of water
• about 60 millilitres (1/4 cup) of vinegar
• several drops of food colouring (optional)
• a 400-milliliter (12-ounce) drinking glass
• a waterproof (plastic or metal) tray
• a teaspoon

Place the drinking glass on the tray. Put 15 cm3 baking soda and 15 cm3 laundry detergent to the glass. Add 180 ml of water and a few drops of optional food colouring. Gently stir the mixture to mix the contents of the glass. To display and observe the fizzing and foaming, quickly pour the vinegar into the glass. The mixture will foam up and over the top of the glass, covering the tray with foam of tiny bubbles.

To produce a colour change when the vinegar is added to the mixture in the glass, you can replacement some red cabbage juice for the optional food colouring. For a different colour change, try grape juice.

In this experiment the fizz is produced by a chemical reaction between baking soda and vinegar. Baking soda and vinegar react and one of the products of the reaction is carbon dioxide gas. This gas forms bubbles that are surrounded by the liquid. The laundry detergent makes the bubbles last longer and foam is produced. The volume of the gas produced and attentive in the foam is much greater than the glass can hold so some of it spills over the top of the glass.

Baking soda is sodium bicarbonate. Vinegar contains acetic acid dissolved in water. Sodium bar carbonate reacts with most acids. The products of the reaction with vinegar are carbon dioxide gas, sodium acetate and water. The reaction of sodium bicarbonate to form carbon dioxide gas is the basis of its use as a livening agent in baking. The foam is produced when bubbles of carbon dioxide from the reaction of sodium bicarbonate are intent. As the cake bakes, the bang dries and the intent bubbles of carbon dioxide form the holes in the cake.

## Experiments in Physics

### Experiments in Physics:

Physics is a practical project based on valid experimental support, analysis and rational discussion. It provides knowledge of the physical world. Experiment plays many roles in science. One of its important roles is to test theories and to provide the basis for scientific knowledge. Experiment can provide hints toward the structure or mathematical form of a theory and it can provide proof for survival of entities involved in our theories. Physics is called natural philosophy and is a science of energy and matter and relations between the two. Physics includes the study of material and energy as related to motions, heat, light, and force. Modern extensions of physics have extended to include nuclear physics, particle physics, plasma physics and cryogenics.

## Create Lightening

Lightning

Lightening is a beautiful and scary natural element. You can hear its thunder from miles and miles away and see it light up a completely dark sky. Now you can make your very own lightening in your own home.

Purpose

To create your own lightening using just a few simple tools and things that you can find already in your home or at the grocery store. You will be able to see and possibly hear the lightening as it’s created!

Required materials

• Foil pie plate
• Writing pen (ball point will work very well)
• Tack
• Sock (must be wool)
• Styrofoam block
• Glue
• Video camera, if you have one
• Notebook paper or journal

Experiment Time

Procedure

1. Gather your materials on the kitchen counter.
2. Begin by placing your nail in the pie plate from the bottom up. The sharp point should be sticking out of the top of the pie plate.
3. Place the pen in the pie plate. You may need to use a drop or two of glue to get the pen anchored really well. If you do use glue, let it dry before proceeding.
4. After this do not touch the pie plate with your hands.
5. Take the smack and rub the wedge of Styrofoam quickly. This will create the negative charge you need to create the lightening spark.
6. Pick up the pie plate by holding on to the pen and push it down on top of the Styrofoam block so the tack is lodged into the Styrofoam and anchors it in place.
7. Turn out the lights. If you have a video camera, you can film the lightening spark.
8. Bring your hand towards the pie plate slowly, without touching it. This will complete the experiment.

## Matchbox Guitar

Traditional guitars are played acoustically where the sound produced is a result of the vibration of the strings and modulated by a vacant body. Electric guitars produce an electronically manipulated tone when played through amplifiers. As the guitar strings are plucked, the guitar pickup senses the vibrations from the strings and sends along an electronic signal to the amplifier. The peaked reads the signal and converts it into a variable clear sound by boosting it through a speaker system. The guitar strings were made from cat bowels. These day strings are made from nylon, horse hair, bronze and steel.

Required materials

• Empty matchbox
• 4 small rubber bands
• Balsa wood (very soft and light wood with a coarse open grain, suitable for carving)
• Craft knife

Experiment Time : it takes About 15 to 30 minutes.

Procedure

1. Cut the piece of balsa wood into a flat triangular shape so that its length is a little longer than the width of the matchbox.

2. Place the triangle across the width of the matchbox so that the pointed end is hanging over. You don’t need the piece that is hanging over, so cut it off.

3. Lay the link on the closed matchbox. Open the matchbox so it’s about three-fourths open.

4. Put the rubber bands over the matchbox lengthwise and space them evenly. Make sure the rubber bands are tight. This can be done by opening the matchbox a little more.

5. Lift your bridge so that it stands up.

Result

The matchbox guitar is an example of a plucked string instrument which also includes mandolins, balalaikas and bass guitars. The instrument works by plucking the string with your finger tips. The different pitches are created by placing your finger at different points along the string to either shorten the pitch or lengthen it based on the vibration. The strength at which the strings are plucked also affects the frequency and pitch of the sound as it can create a larger vibration or a smaller vibration.

You will need

• 3 small torches
• Red, blue and green cellophane
• Baking paper
• Scissors
• Sticky tape
• White, vertical surface (such as a wall or door)
• Small object (such as a cork or a salt shaker)

What to do

1. Roughly measure the size of the front end of each one of your torches.
2. Cut a square of red cellophane large enough so it will completely cover the end of the torch. Repeat this step by estimating and cutting a similar square of baking paper.
3. Place the cellophane over the end of the torch and sticky tape its edges in place, so the light can pass through it. Place the baking paper over the cellophane and sticky tape it in place as well.
4. Repeat the above steps for the blue and green cellophane giving you three torches that shine red, green and blue light. The baking paper diffuses the light, giving you an even glow.
5. Find a dark room and a white surface. Turn on each torch and shine them on the same spot. What colour is the light?
6. Put the small object in front of the torches.
7. Glow only two torches on the same spot.

## Candle Swing

Material Required

• 1 Candle (cut from both the sides)
• 2 Glass
• 1 big needle
• 1 matchbox

Experiment

1. Cut off an ordinary candle on both sides so that you get to the wick.
2. Stick a heated knitting needle in the middle of the length.
3. Put the candle horizontal and put ends of a needle which stretch out of the candle on two glasses.
4. When we light up both wicks, the candle starts to swing.
5. When a drop of wax falls down on one side, the candle loses its balance and preponderates to the other side.
6. There the flame grazes the candle, so that a drop of wax falls down also on this side.
7. Candle loses its balance again and preponderates back again. So the candle swings until it runs short.

## Wine and Water Exchange places:

Material Required

• 1 Glass
• Water
• Wine Red
• 1 Pasteboard

Experiment

1. Cover up a glass of water with a thin pasteboard turn it over and put it on the glass of red wine. Continue reading
