This afternoon Year 2 were trying to find out how they can make a piece of paper waterproof.

They took a piece of regular paper and looked at what happened when water was dropped on it.  They used the same amount of drops each time to make it a fair test.

They then experimented with different techniques trying to make their paper waterproof.

They used

• plain paper
• wax crayon
• pencil crayon
• oil pastel
• felt tip
• chalk
• cellotape.
•  

Which technique do you think worked best? Why?

Which was the worst technique?
