Investigating paper for Santa

This week we received a letter from Father Christmas asking for our help. His mischievous elves have made clothes out of his waterproof sacks that he keeps his presents in. He needs to use a wrapping paper that is waterproof in case it rains on Christmas Eve. Year 1 had to find out which paper (from Santa’s workshop) was waterproof for him to use. We all carried out a fair test and put water on each type of paper to see if the water went through. The children found that the tin foil was the best and this is what we have told Father Christmas. Well done Year 1!
