Here are some easy experiments for kids that they can perform at home or at school without any hassle at all:
- Experiment One - Plants grow towards Sunlight
A sapling, a shoe box, a pair of scissors, black paper
Take a shoe box and cover it with black paper. Then make a hole in the box and place the sapling in the shoe box and keep it on the windowsill. Open the lid of the box everyday for some time to water the plant and then cover the lid again. After three to four days open the lid and you will observe that the plant has grown towards that direction of the hole from where the rays of sun entered the box.
The conclusion is this that plants need sunlight for their growth and other life processes and thus they grow towards sunlight. You can again try the experiment by taking another box and this time making the hole in the opposite direction. You would notice this time that the plant grows towards the opposite direction, which is the direction of sunlight.
- Experiment Two - Freezing of Water
Water, freezer, plastic container with a lid
The plastic container has to be filled with water and then the lid has to be placed tightly. Now the container that contains the liquid water has to be placed in the freezer and leave it that way for at least eight hours. After eight hours the container should be taken out of the freezer. Observe that the lid of the can has come off and the liquid water has become solid ice.
When the temperature is decreased, the states of matter change. Water (liquid) changes to ice (solid) and when this happens the volume increases and it takes more space, which is why it pushes the lid of the container and the lid, come off.
- Experiment Three- Floating and Sinking
A bowl, water, an orange
The bowl has to be filled with water and then put the orange on the water and see if it sinks. Try and sink it by pushing it downwards in the water. Now peel the orange and place it on the water surface and see if it sinks. Observe that this time the orange sinks.
The orange did not sink the first time because there are numerous air pockets in the orange peel, which make the orange lighter than water thus making it float on the water surface. Once the orange is peeled off the air pockets are also removed along with the peel as a result of which the orange sinks the next time.
