Physics Experiments at home

Physics is an important science subject that helps us to understand the world we live in. In Physics you can enjoy learning about topics such as energy, force and magnets with our cool physics facts. Science is an attractive subject with many wonderful things to learn and discover.  One of the best ways for children to learn about all types of science is by making it fun. Involving children in the scientific experiment process is a great way for them to get to know about education about all types of science from biology to astronomy to physics.

The gravity, electricity, magnets, gears are most liked physics topics. Experiments are an awesome part of science that allow students of all ages to engage in fun and exciting hands on learning experiences that they are sure to enjoy.

  1. Office Chair Physics Experiments

The position of your body can speed things up or slow them down when you are moving around at your desk.

You will need: a rotating office chair, A person and some open space where we can do this experiment.

Now learn about this Experiment:

  1. Have a seat in the office chair.
  2. Make sure that your feet are not touching the ground. Stretch your arms out wide and have your buddy give you a little spin on the chair.
  3. Now pull your arms in close to your chest and see what happens. Start with your arms out wide and then let your body take you for a rotate.
  4. As soon as you pull your arms close to your body you will start to spin faster.
  5. If you put them back out, you slow down again. This is because when you rotate or do any motion you have something called momentum.
  6. If you’re running quickly it takes more effort to come to a stop than it does if you are running slowly. Your energy depends on your mass and speed.
  7. The higher speed running has a higher energy than the lower speed running.

When you are rotating, you have got a quality called angular momentum which depends on your angular velocity.  Your speed around the spherical motion and a quantity is called moment of inertia. Moment of indolence measures how much your body will oppose a change in angular velocity and it is related to how your mass is distributed. Moving your arms in and out changes your moment of inertia. Momentum is always sealed.  During a motion, when one quantity changes (like your moment of inertia) the other must also change to make up for the difference.

Angular Momentum = Angular Velocity x Moment of Inertia

2. Sound in Space

This demo will discover the possibility of sound in space and the ways we can communicate with astronauts on the International Space Station.

What You Need

  • Empty Snapple© bottle
  • Matches
  • A small bell
  • Stick tack/tape
  • A Popsicle stick/any short, firm stick

Experiment

  1. Take the small bell and join it to the Popsicle stick.
  2. Attach the opposite end of the stick to the bottom of the Snapple bottle cap.
  3. Shake the bottle cap to verify that the bell still makes a visible rattle.
  4. Now screw the cap onto the bottle and shake.  You should be able to hear the bell tune inside of the bottle.
  5. Remove the cap and remove the bell from the bottle.
  6. Light two matches and drop them into the bottle.
  7. As soon as the matches are dropped in, screw the cap and bell back onto the bottle.
  8. Wait until the matches are extinguished and the bottle cools if it is hot.
  9. Then shake the bottle once again. The bell should be much quieter than before if it’s even perceptible at all.

3.  Floating Rice Friction

Friction is a force we hear about everyday but we can’t underestimate its power.

What You Need

  • An empty plastic water bottle
  • Uncooked rice
  • A pencil

What to Do

  1. Fill the empty bottle to the top with rice.
  2. Slowly push the pencil down into the bottle and slowly pull it up again.
  3. Repeat this motion it will become ever more difficult to push the pencil down.
  4. Finally, you won’t be able to pull out the pencil anymore.
  5. You will be able to pick up the bottle with the pencil instead.
  6. When the rice is inside the bottle, there are grains next to one another but there is a little bit of space an air pocket in between each grain and its neighbour.
  7. Press the pencil into the bottle the grains of rice are pushed together to make room for the pencil.
  8.  Push the pencil in the grains combine closer and closer together until they are rubbing against neighbouring grains of rice.

This is when friction comes into play. Like when you rub your palms together, rice grains rubbing against each other feel a force resisting their motion. Once the grains are packed so closely together that the friction force becomes overwhelming, they will push against the pencil with a strong enough force to render the pencil stuck, allowing you to pick up the whole bottle with the pencil.

4. Big O’ Glass of Sunset

See the sky is blue and a sunset is orange, all in a glass of milk!

what Material you needed :

  • Tall clear glass of water
  • ½ tablespoon of milk
  • Flashlight

Instructions to do this experiment:

  1. Blend the milk into the water.
  2. Glow the flashlight from the side of the glass and observe the glass what colour is it showing?
  3. Look directly at the flashlight through the glass, what colour is it?
  4. Shine the flashlight up through the bottom of the glass and look down from the top.

Discussion:

In this experiment the milk particles are doing the dispersal.  Just like the light from the sun, the light from the flashlight is made up of many colours, just like the light from the sun. The milk in the glass is spreading the blue light but allowing the yellow and orange light to pass through. This makes the milk appear blue when looked at from the side, but yellow when looking straight at the flashlight.

5. Physics in the Microwave: Microwave Soap

What you need

  • Bar of soap
  • Microwave
  • Paper plate / shallow plastic container
Microwave

Microwave

What to Do

  1. Place the soap on the plate or thin container and put it in the microwave.
  2. Set the microwave for 2-3 minutes, turn it on, and watch the soap for the entire time.
  3. Let the soap cool for a few minutes and then take it out of the microwave.
  4. Be sure to clean out the microwave when you’re done.

Experiment

  1. Soap contains small pockets of air that have water vapour intent inside of them.
  2. Like the moisture inside of a popcorn kernel, the water vapour inside of soap heats up when the microwave is turned on.
  3. This leads to areas of high pressure inside the soap.
  4. Ultimately the softened “walls” of the bar can’t hold up to the pressure and the soap starts to bubble and expand. As the soap cools down it stiffens up but keeps its new shape.

  6. Glowing Hands

Can you think of a way to make your hands glow in the dark

For this experiment you will need:

• A black light
• petroleum jelly
• latex gloves if you don’t want to get your hands untidy
• someone to turn on the black light for you.

Experiment

  1. If you have Latex gloves put them on your hands.
  2. Reach into the jar of petroleum jelly and dig out enough jelly to cover both hands.
  3. Rub the jelly well over both hands, and then ask someone to turn off the lights in the room and to turn on the black light.
  4. Hold your hand under the black light.
