Testing Materials

As part of our 'Shine' topic, Tamatoa (the famously shiny crab from Moana) has reached out to our class for some help. His dazzling shell is starting to become rusty so he wants to make a coat to protect it when underwater. As Year 2 are currently learning about materials, they seemed the perfect people to ask. 
Kingfishers discussed the properties that his coat will need and decided that the priority to prevent rust is being made from a waterproof material. They then planned what they would need and how they could fairly test a variety of materials. We looked at the materials first and made some predictions about which material we thought would be the most waterproof and which would let lots of water through it. 
The children loved carrying out their experiment as planned. They were consistent with measures such as the amount of water they poured on top and for how long they timed before removing the fabric.
