Concord Consortium: Sparks Tutorial: Finding the Cutoff Frequency

How do you create the sound of hydrogen? An interesting video explains how to use mathematical formulas and sound software to translate the spectrum of light that comes from hydrogen into a sound. The resource walks through each...

Explore macromolecules and the smaller molecules that make up living organisms in this module.

Explore how Newton's three laws apply to the world of atoms and molecules. Start with the originally contradictory observation of Brownian motion. Then, each law is addressed at the atomic level.

Learn how to use an oscilloscope.

Explore the pattern of earthquakes on Earth, including magnitude, depth, location, and frequency.

A tutorial describing the characteristics of simple harmonic motion. Utilizes animations, mathematical equations, and interactive questions to teach essential principles.

In this module Activity 4 investigates How does a spark trigger an explosion?

Students construct a model of chemical reactions involving energy and electrostatic interactions and compare reactions and changes in energy through the following activities. Activity 1 What energy changes occur during an explosion?...

In this module Activity 3 investigates What changes in energy occur when atoms rearrange during a chemical reaction? This activity explores the relationship between energy and chemical reactions. A bonus reading includes Energy and...

In this module Activity 1 investigates What energy changes occur during an explosion? Students make observations of exploding balloons and a simulation, and ask questions about what occurs during an explosion, setting the scene for more...
