In this human behavior science fair project, the student will learn about Piaget's developmental stages and the Theory of Conservation. The student will investigate the age at which children understand the equality of numbers and mass....

Young scholars analyze the chemical equation for the reaction between vinegar and baking soda. They observe that the gas produced in the reaction is also part of the products of the written chemical equation.

On this site, find a variety of materials to help learners understand the conservation of matter. Create lessons that allow students to measure and graph quantities that could show even if matter is heated, cooled or combined with other...

Second graders explore the concept of law of conservation of mass.

Where does energy come from? How is it sustained? What does the Law of Conservation of Energy do? Find out!

After observing a demonstration of a chemical reaction between a burning candle and the oxygen in the air, students use atom model cut-outs to model the reaction and see that all the atoms in the reactants show up in the products.

An article describing Dalton's atomic theory. Learn how this theory was the first attempt to describe a fundamental part of matter, atoms. Article also discusses where the theory is incorrect based on the knowledge we have today.

[Free Registration/Login may be required to access all resource tools.] Using the law of conservation of energy as a starting off point, students use the specific heat equation to perform calculations that relate mass, specific heat,...

In this interactive activity adapted from Wake Forest University, students will observe the effect of mass on velocity and momentum in elastic and inelastic collisions. Includes background reading, a student handout, and discussion...

This lesson focuses on chemical reactions including what they are and an explanation of each part of a chemical equation.

Find out about the essential role energy plays in cell function and in sustaining life. Trace energy transformations as they pass from one living thing to another.

Young scholars examine collisions between two skateboards with different masses to learn about conservation of momentum in collisions.

This lab activity from the Illinois Institute of Technology lets students investigate the impact of collisions upon the velocity and momentum of the colliding objects. Requires understanding of vectors.
