Discover how the periodic table tells the story of its elements. Learners begin by studying the makeup of several mixtures. Their analysis leads to a discussion of elements and the periodic table. As they dig deeper, they understand the...

In this physics 240:10 instructional activity, students calculate the speed and distance as presented in the given word problems. Students apply their understanding of Hooke's law to answer the questions provided.

Students examine the importance of good quality safety gear. In this investigative lesson, students will tests various polymers, collect data, and analyze the data to determine which polymer is best for safety helmets. They will design a...

All sodium carbonate may not have the same amount of carbonate, but it should have the same percent. Learners write and balance an equation to predict the chemical reaction between sodium carbonate and zinc acetate. Through the lab...

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 apply the principles of chemistry to investigate the concept of how a hydrogen powered car works. They study the electrochemical reactions that provide the energy source. Students also record observations in the functioning of a...

In this chemical reactions worksheet, high schoolers answer 20 multiple choice questions about chemical equations, chemical formulas, oxidation and reduction reactions and acids, bases and salts.

Students investigate whether or not chewing gum should be considered eating using the law of conservation of mass to reason that the portion lost of the original mass of gum must be swallowed.

This lab experiment shows students that mass is not gained or lost during a chemical reaction. Lab also includes a set of lab questions that requires students to balance the chemical equation for the reaction that occurs in this lab.

A lab activity where students investigate the structure of polystyrene by breaking down the cross-links between bonds using acetone. The experiment will help them to understand how mass is conserved despite the drastic change in volume,...

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...

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...

Use this interactive, animated lab to explore conservation of mechanical energy.

Hang various mass weights on spring scales while you adjust the spring stiffness and damping in this online activity. Slow down the action, take it to another planet, or watch the amount of potential, thermal, and kinetic energy.

Manipulate the mass of a weight and the length of string in this interactive pendulum simulation. Change the speed, friction, and gravity to make the pendulum swing change as measurements are displayed on the screen. Younger students can...

In this chemistry lab, students will investigate chemical changes that occur when acids and bases react. It is meant to introduce the concepts of chemical changes, gases have mass, conservation of mass, and balancing equations. Students...

This is an extensive learning module on biodiversity and its decline. It looks at ways biodiversity is threatened, the possibility of another mass extinction, the causes and consequences of habitat loss, factors that drive biodiversity...
