In this experiment, students are if the law of conservation of mass holds true for both physical and chemical changes. Students observe two color-changing reactions, one physical and one chemical, and use scales to determine if the mass changes throughout the reaction.

MS-PS-1-5: Develop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved.
In this activity, students will use computational thinking to write a code sequence for a drone to survey an arctic map. This activity is based on the work done by Northrop Grumman in Operation Polar Eye.
