Learners analyze the amount of space required to pack round objects. In this geometry instructional activity, students practice using space economically by practicing packing spheres into beakers. They then translate this concept to...

In this energy lesson, students create calorimeters out of soda cans and use them to calculate the amount of energy stored in different types of wood.

Students make spinners to investigate rotational inertia, rotational speed, angular momentum, and velocity. They make two sets of spinners that have different mass distributions and shapes. They complete a worksheet while experimenting...

Students study polyatomic ions and write binary and ternary ionic chemical formulas. They explore putting together different monatomic ions and coming up with as many chemical formulas as possible. They play a game similar to memory...

Students investigate chemical reactions. In this chemistry instructional activity, students burn magnesium and record the mass. Students list five chemical reactions they see everyday.

Eighth graders analyze physical change in mass. In this chemistry instructional activity, 8th graders describe, measure and calculate the amount of physical change occurring in mass before and after the change. Students should be...

High schoolers investigate the concept of the Einstein's Theory of Relativity while conducting research using the internet and following the outline of the objectives to guide the information search. The lesson plan includes background...

Students practice estiminating and measuring angles. After watching a short video, they identify angles in objects in the classroom and their homes. In groups, they participate in activities in which they are given a scenerio and are...

Students, through hands on games and activities, discover how bats live and how bats benefit ecosystems. They play a game designed to show them how echolocation works and another to show how mother bats locate their young through their...

[Free Registration/Login may be required to access all resource tools.] The law of conservation of mass and an example.

[Free Registration/Login may be required to access all resource tools.] Explores the conservation of mass and energy in nuclear reactions and Einstein's equation.

[Free Registration/Login may be required to access all resource tools.] Explains Law of conservation of mass and why chemical equations must be balanced.

Everything in our universe has mass- from the smallest atom to the largest star. But the amount of mass has remained constant throughout existence even during the birth and death of stars, planets and you. How can the universe grow while...

[Free Registration/Login may be required to access all resource tools.] Describes the law of conservation of mass.

Learners conduct a hands-on investigation to determine how matter, changing state, effects the property of weight. Students will collect data and graph their results. Resources include step by step instructions, a data worksheet, videos...

An interactive simulation with weights and scales that teaches about balancing chemical equations and conservation of mass. This simulation can either be downloaded or played online and includes handouts, lesson plans, and additional...

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.

On this site, find a variety of materials to help students 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...

An interactive simulation that teaches about springs, Hooke's Law, and conservation of energy observing changes in kinetic, potential, and thermal energy by adjusting the stiffness and damping of springs holding various masses. This...

An interactive simulation that teaches about periodic motion, simple harmonic motion, and conservation of energy. Observe one or two pendulums to determine how the swing is influenced by the length of the string, the mass of the pendulum...

Mechanical energy is the most easily understood form of energy for students. When there is mechanical energy involved, something moves. Mechanical energy is a very important concept to understand. Engineers need to know what happens when...

In this interactive physics tutorial, students examine some real-world applications of the impulse-momentum change theorem, more specifically, some physics in action in the real world.

This lesson teaches the concept of a watershed and why it is important in the context of engineering hydrology. Students learn about runoff and how we visualize runoff in the form of hydrographs.

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