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

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

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.
