Don't waste all that carbon dioxide. Scholars first produce carbon dioxide by mixing baking soda and vinegar. They measure the masses of the reactants and products to verify the law of conservation of mass. As a culminating activity,...

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...

It's the law—every action requires a reaction, no matter how small. Pupils experience two demonstrations of Newton's third law of motion as it relates to thrust in the 10th segment of a 22-part unit on flight. Using their mathematical...

Young scientists learn that seeing isn't necessarily believing when it comes to the states of matter. After performing a fun class demonstration that models the difference between solids, liquids, and gases, children complete a series of...

Investigate the relationship between temperature and pressure. Learners change the pressure of a sample of air and monitor its temperature. They learn that as air decreases its pressure, its thermal energy converts to kinetic energy.
