Floating Eggs: Weekly Science Project Idea and Home Science Activity Spotlight

Ocean sciences density and salt water project to make an egg float / Hands-on science STEM experiment

In this week's spotlight: an ocean sciences family experiment and science fair project. Some things float in water and some do not. Knowing the density of the object and the density of the water helps explain what is going on, and you can observe and talk about the buoyancy of an object. But adding salt can change what happens. Why? In this hands-on science experiment, you set up a series of dilutions to see at what point an egg goes from sinking to floating in salt water.
