Conservation of Mass
Students conduct an experiment to compare the total mass of products to the mass of reactants. In this conservation of mass lesson plan, students devise an experiment to show that matter is neither created or destroyed in a chemical...

The Law of Conservation of Matter
The Law of Conservation of Matter can be complex for young scientists to fully grasp. Use this experiment to help simplify the process as pupils perform two experiments to determine mass: one that melts a substance and the other that...
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...

Conservation of Mass
How do you teach a student with visual impairments about the conservation of mass? You use tactile models that represent the theoretical concept. Baking soda and vinegar are used to add gas to a deflated balloon. Learners will feel the...

Conservation of Mass
For this conservation of mass worksheet, students experiment with vinegar, baking soda, a balloon and a flask. They compare the mass of the closed system of reactants before the experiment to the mass of the products after the experiment...

Masses and Springs
Have you ever stretched out a Slinkie so much it wouldn't go back to its original shape? Slinkies, like all springs, follow Hooke's Law. A simulation uses springs and masses to demonstrate kinetic, potential, and thermal energy. It...

Investigation: Conservation of Energy
By rolling marbles down a six-foot length of track, physical scientists determine how much energy is lost to heat. It is recommended that you opt for the foam pipe insulation track because more friction slows the marble, allowing...

Conservation of Mass
In this conservation of mass worksheet, students design an investigation to demonstrate the Law of Conservation of Mass. Students describe their investigation, collect data, graph the data and write a conclusion about what they discovered.

Conservation of Momentum
Assist your class with understanding collisions as they apply the Law of Conservation of Momentum. Pupils measure the momentum before and after manipulation of two objects so that one strikes another in an inelastic collision. The lesson...

Law Enforcement - Explosions
How do law enforcement officers determine the strength of an explosion based on the movement of objects around the point of origin? Scholars inspect the relative mass and velocities of two cars before and after an explosion. They perform...

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...

Impulse, Momentum, and the Conservation of Momentum
What happens when two worlds collide? In the first of several activities, future physicists experiment with colliding ball bearings or Newton's cradle. Another activity requires the use of an air track with cars to examine collision....
