Students learn about polar and non-polar molecules and density by making their own lava lamps and exploring how they work.
Some media may contain mature content. Discretion is advised when viewing with students.
The materials needed to create the lava lamp are: a clear bottle or jar, vegetable oil, water, food coloring, and Alka-Seltzer. Students can be broken up into groups to make their lava lamps, or the instructor can make the lava lamp while the students observe.
