Quantum tunneling plays an important role in nuclear fusion, the energy source of the sun. This simulation explores tunneling, double wells, and covalent bonds by allowing individuals to manipulate potential and total energy to learn...

How can heat power an engine? Scholars observe a heat engine working and control variables to determine the most efficient setup. They change the amount of heat input as well as the stroke length. Energy efficiency numbers prove the...

High voltage power lines deliver electricity to homes, but each home requires low voltage. How does the energy get converted so it can be used safely? Pupils explore alternating current and transformers through a simulation. They control...

Why are there launch windows when traveling to outer space? Scholars explore the trajectory of traveling from one planet to another. By adjusting the departure and destination planets, as well as the launch date, they observe the ideal...

Transcription makes copies of the instructions inside all living things. Scholars use the simulation to separate DNA and transcribe the RNA. They see a demonstration of the nucleotide pairings as well as the start and stop instructions.

She threw sodium chloride at me—that's a salt! Scholars match acids to their formulas as well as their salt compounds. Completing a series of three gridlock puzzles reinforces each of the matches in a logical manner.

The ionic formula for banana would be BaNa2. Scholars work their way through four puzzles reviewing ionic formulas. Each puzzle requires scientific knowledge as well as logic and problem-solving skills.
