Summary:
In this picture book it informs the reader of what things can float and also what things will sink.  It goes on to explain why certain objects sink and why certain objects float such as the air.  It gives examples of bottles being used with air and sand.  Throughout the book it gives bigger and real life examples such as a floating boat on the water or a submarine floating below the water.

Activity:
Have students experiment with floating and sinking objects.  Have students fill one bottle with sand and the other with the air.  Students will then place bottles in the water and watch as one bottle will sink and the other will float.

Recommendation:
This is a great concept book for students to listen to and also experiment with.  Have students read this book either aloud or silently, and then have them actually perform an experiment using the information the have already just read.
