Give each child activity sheets and pencil. You may want to give each group one set of activity sheets to be done together. Remind them they are to do activities as they go through aquarium. They can ask chaperone or an Aquarium worker for help. Children draw things they find with colors and shapes on the paper.
Children find as many fish or creatures as they can with each letter.
Be sure all groups have a chance to visit gift shop. There are many inexpensive small animals and books at the shop. When students return to school, as time permits, you may want them to write about their favorite tank and draw a picture of it. Discuss worksheets done at Aquarium together. Discuss children's favorite tanks and what was in them.
