A summary of projects about making things float and sink.

Understanding the basics of density and how that affects flotation and buoyancy comes to life in a step-by-step guide that presents simple but effective experiments that include creating a hydrometer and a jet boat

Hands-on experiments enhance understanding of why things float, density of liquids, floating liquids, floating and sinking eggs, making a hydrometer, and other related topics.

Cooper has the clever idea of making his mom pancakes for her birthday, and his friend the moose offers to help. The moose claims he's the best chef in Alaska, but is he really? Find out if Cooper's mom is happy about the surprise awaiting her in the kitchen!

It can be surprising which objects float and which don't. An apple floats, but a ball of aluminum foil does not. If that same ball of foil is shaped into a boat, it floats! Why? And how is it possible that a huge ship made of steel can float? Answering these questions about density and flotation is David A. Adler's clear, concise text, paired with Anna Raff's delightful illustrations. Activities that demonstrate the properties of flotation are included.

Two delightfully anxious friends learn that they can overcome anything—even gravity—in this humorous and heartwarming picture book from bestselling author Aaron Reynolds and illustrator Debbie Ridpath Ohi. Bob the puffer fish and his best buddy Sea Monkey may be little but they’ve got one ocean-sized problem. Sea Monkey’s terrified he’ll sink straight to the bottom of the ocean. After all, he’s heavy, and all heavy things sink, right? Bob on the other hand is worried that his puffed up frame will float up above the surface. He’s light, and all light things float! How will they stay together when the forces of gravity are literally trying to pull them apart? By holding hands, of course! Sea Monkey and Bob learn that sometimes the only way to overcome your fears is to just keep holding on…

Introduces the concepts of floating and sinking by following a fictional captain on the high seas who wonders why his boat floats and his treasure sinks.
