We were set the challenge to find a waterproof material which would be suitable for a coat for Pirate Tom to wear on his next adventure.

After making our own predictions, we discussed what we would see if a material is waterproof or absorbent.

We then worked collaboratively, just like Team Ant, to investigate the following materials:

• Plastic
• Felt
• Cotton
• Denim
• Paper
• Rubber

We used a syringe and, to make it a fair test, we squirted the same amount of water onto each material.

After careful observations and measurements, our results showed that plastic and rubber are waterproof because the water didn’t soak through these materials, whereas, the others were absorbent.
