Christmas Cookie Mystery – Science investigation
Mrs. Claus needs your help! Each Christmas, Mrs. Claus makes a batch of her special sugar cookies to give Santa all the energy he needs to deliver presents to all the good little boys and girls around the world. A bad little elf has snuck into the kitchen and messed up all the special baking powders. Students need to find out the which of the powders is the cookie mix! I was given this resource at an NQT conference and thought I would share it.
