Investigation: Conservation of Energy
By rolling marbles down a six-foot length of track, physical scientists determine how much energy is lost to heat. It is recommended that you opt for the foam pipe insulation track because more friction slows the marble, allowing...

Energy Forms and States Demonstrations
Does a tennis ball have energy? What about a bowling ball? Demonstrate concepts of different forms of energy forms and states with a variety of objects. Using the equations for potential and kinetic energy, learners determine the amount...

Energy Flow in Ecosystems
Emerging biochemists more fully understand the flow of energy in ecosystems as they explore the laws of thermodynamics and relate them to energy transfer in food chains. They also investigate heat loss from the human body and how...

Energy Conversions
What energy conversions occur in the operation of a device? Small groups investigate devices and the energy conversions that occur. The groups create energy flow diagrams with added conversion processes for each of the devices...
Herff Jones Education
Chemical Energy
Provide the class with a quick lesson on chemical energy as they are assisted in creating hot and cold packs to demonstrate energy transfer between objects. They observe the energy change in matter as it transforms and distinguish...

Introduction to Climate
Begin a full lesson on climate change by demonstrating how carbon dioxide gas contributes to increased temperatures. Be aware that pressure inside the antacid-containing bottle in Activity 2 may cause the lid to fly off; keep viewers at...

Build Your Own Biogas Generator
What is biogas and how is it made? After examining background information about the sources of biogas and biogas generators, class members follow the provided information and build a biogas generator that can be used in the classroom.

Motion in the Ocean
How do temperature changes affect ocean currents? Scholars explore convection currents by demonstrating the flow of water in a baking dish. They use ice, heat, and food coloring to see currents. Then, they draw conclusions about their...

What Makes a Gas, a Greenhouse Gas?—The Carbon Dioxide Dance
Investigate a heated topic in environmental science. Scholars team up to play the parts of gas molecules in the atmosphere. As the teacher moves about, acting as the electromagnetic wave, learners react as their molecules would to the...

Pixel This!
Did the image I drew match the image you saw? By simulating a satellite and a ground station, teams of two transmit data in the form of pixels in order to recreate an image. They use four different levels of brightness, creating slightly...

Climate Is Our Friend…Isn’t It?: Make an Extinction Polyhedron
Climate affects populations in different ways. Scholars research extinct organisms and mass extinctions in part three of the 10-installment Discover Your Changing World series. They create graphic organizers, then fill in the information...
