Lesson Plan - Get It!


The tide rolls in. The tide rolls out. But why?

Why does the ocean water cover more of the beach at certain times and not as much at other times?

Well, it's all because of the moon and the sun. But they are so far away, you say? That's true, but they still have a great effect on the tides. Find out how.

In this lesson, you will investigate how the moon and the sun affect the tides. Explore the exciting world of tides using a jamming video, an online tide simulation resource, modeling of the tides activity, and some exciting sea projects from which to choose!

  1. Watch Tides, from Scholastic StudyJams!, to learn about high and low tides and how tides are caused by the gravitational pull of the moon and the sun. Test yourself with the brief quiz after watching the video.
  2. Discuss the following questions with your teacher:
  • How are high tides and low tides produced?
  • How often do high tides and low tides occur?
  • What is a neap tide?
  • What is a spring tide?
  • How often do neap tides and spring tides occur?

When you've gotten the idea, continue on to the Got It? section for some great hands-on projects!
