Lesson at a Glance
Chapter 1, Lesson 1: Sand and Salt (pp. 4-7)
The Big Idea
Framework Concept: Change The effects of ocean tides on land are an excellent
example of how places change over time.
- Begin by discussing any experiences students may have had with oceans and
beaches. Encourage students to describe the movement of the waves, and
what the undertow feels like. Help students understand that the waves
pulling the sand from under their feet is an example of how the oceans
change the land--taking land away and giving it back.
- Use a map of the world to show students the coastlines of the different
continents. Cover the ocean labels with paper and have volunteers write
the names of the oceans on the paper.
