Conservation of Momentum: Marble Collisions
What happens to the momentum of an object when it strikes another object? Scholars roll a marble down a ramp so it collides with another marble. By measuring the speed of each marble before and after the collision, pupils answer this...

What Are The Properties of Sea Water?
Ninth graders conduct research on the subject of sea water. They use a variety of resources to obtain information. There are helpful resource links listed in the lesson. In conjunction with the research students make inquiry of the...
Oceanic Research Group
Heat Transfer and Cooling
Astronauts train underwater to simulate the change in gravity. An out-of-this-world unit includes three hands-on activities, one teacher demonstration, and a discussion related to some of the challenges astronauts face. Scholars apply...
Science 4 Inquiry
Maintaining Mass
Can you disprove the law of conservation of mass? Pupils observe the teacher weigh each part of a reaction. Then, the teacher weighs the result of the reaction and everyone sees that the products do not equal the reactants. Then they...
Cornell University
Chemical Reactions
Investigate the Law of Conservation of Mass through a lab exploration. Individuals combine materials to initiate chemical reactions. They monitor for signs of reactions and measure the masses before and after the reactions for...
