This group-based, tide-modeling activity is a great visual that helped Spring and Neap tides click with my students.
Idea: Arrows demonstrate "gravity forces" coming from the sun and the moon. When two arrows line up, the gravity is stronger and students can see how more gravity forces create the higher tides that we classify as spring tides. When two arrows oppose each other, the gravity is weaker and students can see how less gravity forces create the lower tides that we classify as neap tides.
Check pt. boxes go with each challenge and reflection questions allow students to analyze their drawings and discoveries from the lab.
