Wordless picture book
Wave takes the reader on a wordless trip to the beach, where a young girl joyously plays in the waves and discovers the surprises that the waves hold.
Activity 1
Discuss waves. Explain that waves are caused by wind and their oscillating motion is similar to a vibrating tuning fork or guitar string.
Use a jump rope for this outside activity. Take one end and allow the other end to remain free. Ask the students to watch for the waves along the rope. Lift the end and give it a hard, up and down shake. You may want to repeat it.
Back in the classroom, draw the image of the wave going up and down. Try to keep the waves symmetrical. Add a horizontal line through the center of the wave diagram. See this image for details.
Label the crest and trough and discuss how a wave length is measured from crest to crest or trough to trough. Then have the students measure one of their waves in centimeters and millimeters. Make a bar graph to compare their results.
Activity 2
Define invertebrate. Then use this link or a field guide to shells to identify the invertebrates on the back endpapers. Classify the shells into groups. Use the categories of: mollusk (gastropods or bivalves) and starfish, which are not fish, but echinoderms (related to sand dollars and sea urchins). Look for information and learn more about mollusks and echinoderms.
