Solar Effect On Colours

Materials Needed

2 bottles
Black and white Paint
Paint brush


Take 2 bottles
Fill both with water and close the lids
Paint 1 bottle black
Paint 1 bottle white

Open the lids
Keep both bottles in the sunshine for certain time. (we kept for 1/2 an hour)

Record temperature of water in both bottles

Our observation

water in the white bottle - normal 
water in the black bottle - 101 C


Colours have power to attract or detract sunlight or sun rays
Each colour reacts differently to the solar energy
Black colour absorbs heat and white colour detracts heat
