This online calculator converts from one energy unit to another - from gallons to British thermal units (Btu), kilowatt/hours to megajoules, short tons to metric tons.

This interactive provides two scenarios for students to look at issues related to energy and climate change: from the perspective of either a family, or a monarch.

This pair of interactive visualizations allows students to explore basic and more complex concepts around heat conduction, heat capacity and energy transfer. The basic simulation demonstrates how heating and cooling iron, brick, water, and olive oil adds or removes energy from a system and transfers between objects. At the more advanced level, the systems simulation allows students to see that energy takes various forms, as well as how energy flows and changes from one form of energy into another.

This simulation lets learners explore how heating and cooling adds or removes energy. Use a slider to heat blocks of iron or brick to see the energy flow. Next, build your own system to convert mechanical, light, or chemical energy into electrical or thermal energy. (Learners can choose sunlight, steam, flowing water, or mechanical energy to power their systems.) The simulation allows students to visualize energy transformation and describe how energy flows in various systems. Through examples from everyday life, it also bolsters understanding of conservation of energy. This item is part of a larger collection of simulations developed by the Physics Education Technology project (PhET).

Learn about conservation of energy with a skater dude! Build tracks, ramps and jumps for the skater and view the kinetic energy, potential energy and friction as he moves. You can also take the skater to different planets or even space!

Students will: Predict the kinetic and potential energy of objects Design a skate park Examine how kinetic and potential energy interact with each other

Explore how different elements come together to form bonds and compare changes in potential energy and forces.

Set the initial height of a pendulum and observe how potential, kinetic, and thermal energy change during pendulum swings.

Set the initial position of a mass on a spring and observe how potential, kinetic, and thermal energy change when the spring is released.

This simple data visualization allows students to compare primary energy use and several other variables (carbon dioxide emissions, oil consumption) among different countries, including by OECD and non-OECD status. Students have the ability to toggle a handful of different ways to visualize the data, such as on a map, a bar chart, or a line graph.

This collection of STEM (Science Technology Engineering Mathematics) interactive resources is a practical guide that teachers will find useful in helping students achieve curriculum expectations in STEM related courses, build their understanding of science and their ability to engage in science talk, offer explanations about natural phenomena, and develop digital literacy and a sense of global citizenship. The guide also provides instructional design considerations for developing active learning activities, pedagogical strategies, and sample activities.

Through an analysis of water quality in a nearby lake, students are introduced to basic chemical techniques such as titrations (both acid/base and oxidation/reduction), atomic absorption spectrometry, and uv/vis spectrometry
