## 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.
