Book ChapterDigital resources are stored online in your NSTA Library.

Whether or not a boat floats is determined by its shape and density. In this activity, students discover how and why boats float by designing different hull shapes and finding which design holds the most weight. Students record, calculate, and interpret data as they learn about buoyancy in this hands-on activity.

I liked this chapter! I believe what I liked most is that the activity and content is very much applicable and do able in all early childhood grade levels. As I was reading this resource, I thought of the differences in doing this activity with preschool students vs. third grade students. Although modifications would have to be made, it could absolutely be done well. Love this resource!

This book chapter has several detailed activities about floating with lots of resources and assessment ideas. It is a good basic resource.

If you came across this chapter searching for content then this is a great resource with a bonus - the introduction from the book including a framework for how the activities are structured and fit into an inquiry based classroom are also presented. This also happens to be a great activity with detailed instructions to help walk you through the everything from the first discussion to the final grading rubric.
