You will need: a sunny day, ice cubes, coloured dishes, a clock or timer.
1. What do you think will happen? 2. Place 1 ice block on a white dish and 1 ice block on a black dish. 3. Place both side by side in the sun and observe the changes. 4. After 1 hour what changes have occurred on each dish? Describe these. 5. Repeat with 2 ice blocks on each dish. What changes have occurred after one hour? Describe these. 6. What happens if you repeat these experiments with the white dish and a different coloured one – not black? 7. What have you discovered? Is it what you had expected?
