|Life in Intertidal Zones|
|System Description||This lesson focuses on the Intertidal zone system
Important structures in the system:
Matter and Energy Transfers:
Forces acting on the system:
|Lesson 1. Modeling Tidal Action
Students create tide simulations
Start by revisiting the big questions and what they observed and concluded in their investigation.
Students write in their notebooks any new ideas they have for the question they addressed at the beginning of Lesson 1.
Show the PowerPoint of the 5 tidal zones:
In large group discussion while students take notes:
Each student picks one plant or animal that lives in estuaries in this region. Some teachers might want to ensure there are representatives for each of the five tide zones and include both plants and animals. Don't forget plankton. Each student creates a report covering at least these topics:
