Here in this activity, the children will be allowed to see the effects of the sun radiation on different substances.

Materials Needed:

• Crayons
• Pieces of Chocolate
• Ice Cubes
• Cold Water
• 4 containers
• Stretch Wrap Roll

Method:

1. Place each substance in a different container and cover them with stretch wrap roll except for the one containing the cold water.
2. All the children are to dip their finger in the cold water so as to get a feeling of its temperature. Then cover it with stretch wrap roll.
3. Place all containers directly in the sun and leave them for about 5-6 hours.
4. After 5-6 hours in the sun, remove the plastic wrap and see the differences in the substances before and after the experiment. Remind the children how the water felt before by allowing them to dip their finger in the container full of cold water. Then tell them to place their finger in the water that stood in the sun and note the difference in temperatures.

Learning Point of this activity:

To help children understand that the sun radiates heat and can melt and make objects hot.

It can promote higher order thinking skills in children when predict, analyse and assess, and develop hypothesis about the objects before and after being exposed to the sun.

It can enhance and improve children’s senses when feeling different textures of the objects before and after the experiment

It encourages children to communicate their thoughts and thus it helps in expressing and describing themselves better.

To understand how strong the sun is on us, and so this will prepare them for the next activity that will be about protecting ourselves from excessive heat from the sun.
