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 dams support bodies of water? Scholars engage in a hands-on STEM activity where they design, build, and test dams to learn about bodies of water and how humans use natural resources. They learn how criteria and constraints affect...

Planning a unit on simple machines? Save some time and energy with this collection of lessons and activities that explores how these devices are used in the real world to make life a little easier. 

The potential of the energy in the class is moving. The third segment in a six-part unit on energy provides a deeper understanding of kinetic and potential energy. Learners understand the relationship between mass, speed, and energy and...

Students investigate the difference between potential and kinetic energy. They examine the formulae associated with both types of energy. They complete how quickly a pendulum with swing by converting potential energy into kinetic energy.

Young scholars observe a demonstration presented by the teacher covering different types of energy. They participate in an experiment where they study numerous physics vocabulary words and visit websites that demonstrate examples of...

What is water worth to you? The answer probably depends on many different variables. Learners explore the value of water in space and what it takes to transport the resource to locations in a galaxy far far away. They then consider...

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 explore the concepts of potential and kinetic energy by bouncing assorted balls on different surfaces and calculating the momentum for each ball. They give examples of collisions and momentum in sports and understand that...

Students learn about material balances, a fundamental concept of chemical engineering. They use stoichiometry to predict the mass of carbon dioxide that escapes after reacting measured quantities of sodium bicarbonate with dilute acetic...

Includes exhaustive information and a wealth of activities pertaining to aerodynamics and the physics of flight.
