Chunky Chalk
This week Room 6 has been busy following instructions to make their own chalk.
How did we make it?
You need:
1 cup of plaster of Paris
1/2 cup of water
Coloured dye
1 plastic cup
1 spoon
1 ziplock bag
Method:
1. Put one cup of plaster of Paris into your plastic cup.
2. Add 1/2 cup of water.
3. Add a few drops of coloured dye.
4. Mix with a spoon until the mixture is smooth and fizzy.
5. Pour the mixture into a medium sized ziplock bag.
6. Hang bag on a line with a peg and wait 24hrs until the mixture is completely dry and hard.
7. Remove it from the ziplock bag and enjoy using it on the concrete.
Wow Room 6, this sounds like a super fun activity! It looks like a tricky procedure to follow. You did a great job! :)
