DIY Science Projects for Kids @ Reward Me

Fun With Science

For kids hooked on to games and movies, science is boring! All parents need to do is inject some fun in learning with exciting science experiments for kids! Science projects are a great way for kids to learn how simple items available at home can produce astonishing results.

1. Foam Fantasy:

What you need: A two-litre soda bottle, hydrogen peroxide solution, liquid dish-washing soap, warm water, a packet of yeast, food colouring, a cooking pan.

How it’s done: Place the soda bottle upright in the middle of the cooking pan. Fill the bottle with a half cup of hydrogen peroxide, a few drops of the food colouring, and a few drops of the dishwashing soap. In another bowl, mix together two tablespoons of the warm water and the yeast, allowing the yeast to dissolve. Allow your child to slowly pour the yeast mixture into the soda bottle mixture and watch the foam fantasy unravel.

How it works: Yeast acts as a catalyst and removes oxygen from the hydrogen peroxide at an unbelievable pace. It also makes the container warm which means you have not only created foam but also heat. This is an interesting way to understand exothermic reaction.

2. Colour Symphony:

What you need: A flat tray, 3 different food colours, 1 cup whole milk, liquid dishwashing soap

How it’s done: Pour milk on a tray carefully till it covers the bottom. Add 6-8 drops of different colours on it at varied spots. Next add 5 drops of soap solution and watch the show unravel.

How it works: Wondering how there was an array of colours making magic on a tray? When the soapy solution goes after the fat in the milk to break it down, it causes the colours to scatter and mix creating colourful display.

3. Paperclip Float:

What you need: Paperclip, fork, bowl of water and liquid dish-washing detergent

How it’s done: Put the paperclip on the edge of the fork and gently lower it into the bowl of water. Use a dry paper clip and dry fork for best results. Gently lift the fork out of the water without touching the paper clip. Observe the paperclip. If you look closely at the edge of the paperclip you can see the surface tension holding it afloat. Whenever you are ready, add a drop or two of liquid dish soap near the paper clip and watch what happens.

How it works: When we create the right kind of conditions, water molecules hold on tight together to support any object, for instance your paper clip allowing it to gently float on the surface. The soap disrupts the order of the water molecules and thus the paperclip sinks.

4. Reshape Water:

What you need: A dry plastic comb, indoor faucet, head full of clean dry hair

How it’s done: Use the plastic comb and brush through your hair 10-15 times. Turn on the faucet till you have a very thin stream of water flowing. Immediately bring the comb close to water without actually touching it. The attraction is strong enough to pull the water towards the comb as it is flowing and bend it out of shape

How it works: When you brush a comb through your hair, tiny parts of atoms in your hair called electrons are collected on it. These electrons have a negative charge. As a result the comb is attracted to things that have a positive charge such as flowing water.
