When asked to list everyday objects that require energy, most people list technology that use batteries or electricity. Through hands-on exploration, young scientists discover energy is much more than just circuitry. They play with...

Do all liquids evaporate at the same rate? Young scientists observe the evaporation rate of three different liquids. They measure the time, the temperature, and the change in energy. After comparing the chemical formulas, scholars...

Stephen Perry invented and patented the modern rubber band in 1845. Young scientists put his discovery to work as they use rubber bands to observe entropy and enthalpy. They determine the change in free energy to figure out if it...

Can a small change in laboratory procedures save energy? Scholars test three different methods for heating water in a science lab. Then, they calculate the energy efficiency for each and compare them to determine which uses the least...

See the direct relationship between pressure and temperature using these classic science toys. As individuals hold the glass bulb, the liquid inside reaches it's boiling temperature, which is just a bit above room temperature. As the...

In this lab-based activity, the students will accomplish two sequential goals. The first goal is to understand the law of conservation of energy.The second goal is to use their knowledge in part one to determine the temperature of a hot...

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...
