For this activity, learners 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. They...

Students investigate water by estimating how long it takes to freeze, then see if the ice cube will float in water, and eventually work with other items to see if they sink or float in water.

This investigation introduces the concepts of volume, mass, and density and how they interact. Students will make predictions of whether an object will float or sink after finding mass and volume of an object.
