I now know the reason behind the floating of a boat,making me realize how interesting and fun science can be.

I am a Ph.D. scientist (molecular biologist). I thought this was a terrific explanation of why a boat floats in the context of density and bouyancy. Kids (and adults!) will learn a lot from age-appropriate, well-explained scientific facts and principles. Nice job!

This post was extremely useful. Everything has been explained so well and in such a simple language for kids to understand. .
I am waiting for more such posts.

Thank you for this simple, yet comprehensive explanation. The submarine example is a great way to understand the concept–and I love the experiment suggestion with the aluminum foil boats. I homeschool my four boys and plan to use this tomorrow. Thanks again!

AIMS has a great activity book on density. I’m a big fan of their projects as they incorporate both math and science in the activities my 6th grade students enjoy.
