Last week we received a message from a guy named Doug who was currently working in the Amazon rainforest.

He told us that a big storm had hit and taken out their camp. He needed our help in trying to design some new shelters for their campsite. The shelters need to be strong, waterproof and windproof.

Last week we looked at different shelters and started to sketch what we would like our shelters to look like.

Today, we tested different materials to see which would be the most effective in the rainforest.
