Serc: Mn Step: Sink or Float: All Liquids Do Not Have the Same Density

For Teachers K - 1st
An experiment in density. After a review of floating and sinking of different materials, students test four bottles, all holding four ounces of water, to see if they will float or sink. They each contain a different density of sugar...

Serc: Investigating Density in Solutions: How Can You Make an Egg Float?

For Teachers 3rd - 5th
In this activity, students will learn about density by determining how to make an egg float in water. By the end of the activity, students will understand that density and weight are different and that density matters in floatation. They...

Nagt: Density Mystery Canisters

For Teachers 4th - 6th
Students experiment with items that sink or float, and learn that water's density is equal to one, and objects/solutions with a density greater than one will sink, and those with a density less than one will float.
