Law Enforcement - Hit-and-Stick Collisions
How do police determine the speed of a car that has hit a stopped vehicle? Scholars determine the momentum of the car system both before and after a collision. They identify instances where the law of conservation of momentum appears to...
Curated OER
Matter Test
Physical science learners define matter, explain the law of conservation of matter, and identify compounds according to their state on this twenty-question test. Most appropriate for the introductory physical science class, this resource...

Review Sheet for Matter Test
In this matter instructional activity, learners answer five questions about the law of conservation of mass. They identify substances as solids, liquids, gases or mixtures and they identify given items as matter or energy.
Curated OER
Law of Conservation of Mass
Young scholars work in small groups. They grab a handful of ice, and place the ice in an empty beaker of ice using a triple beam balance. Students heat up the beaker of ice over a hot plat until the ice has changed into water. They...
