While on the trip or back at school have students translate their impressions into a haiku poem or into a drawing. In groups, have students conduct a field survey of a habitat. Give each group a string 1 meter in length tied into a loop. Students should also record their location in the tidepool and the physical features of that location. Back at school create a comparative chart or graph showing the diversity and abundance of animals in different areas of given habitat.
Pollution is one way humans impact the oceans.
In teams, have students pick up trash within a designated area. Ask them to tally the types of trash on their data sheet. Remind students not to pick up broken glass, needles, sharp metal, or anything that might be dangerous. Let an adult know instead. Discuss what effects each piece might have had on marine life if it hadn't been picked up.
