Use these "Energy in a Food Chain" cup labels to create a hands on lesson or a review activity for a science station. You might want to add the “FREE” “Energy in a Food Chain” worksheet. You will need to purchase one package of 3 ounce plastic bathroom cups and if you want to use address mailing labels on the cups, purchase mailing labels that are 1in. x 2 5/8 in. (the same size as Avery template 5150). You can cut out the names and pictures and tape them on the cups if you do not have or want to purchase the address labels.
