The children wrote on the chalk board with different writing materials. They used water based paint, chalk and liquid chalk.
Staff then asked the children what would happen to the paint, chalk and liquid chalk if it rained.
Some children thought the paint, chalk and liquid chalk would disappear.
Then the children tested their theory and used a bottle of water on the chalk board. The children squirted the water on the board and watched as the paint and the chalk washed away. Only the liquid chalk remained on the board.
The children said, “its the liquid chalk, its the liquid chalk, its still there.”
