Could electrons really be as small as the numbers suggest? This is the hurdle for the initial study of electrical properties of elements. Learners view a video to follow the history of the science that led to the discovery of the parts...

Light up the class's knowledge. Pupils build a simple circuit using a battery, wire, and a light bulb and create a diagram of their circuit. The teacher provides a short lecture on a complete circuit, calling attention to the direction...

Better batteries may be just around the corner. Viewers of an engaging video first learn how batteries work and how charging batteries uses a reverse process. They then learn why it is difficult to make better batteries.

Get big results out of a small-scale lab! Young chemists observe the electrolysis of sodium sulfate using a microscale experiment. A colorful indicator solution combined with the production of gas bubbles yields a variety of observations...

Play a little game with your classes! Young scholars expand on their understanding of oxidation/reduction reactions in a game-based activity. They build a Galvanic cell with game pieces while learning about each component and their...

Explore how electricity splits water molecules into hydrogen and oxygen. Learners begin by calculating the voltage necessary to separate the water. They then perform the experiment and measure the ratio of hydrogen and oxygen bubbles.

Your cell phone contains many elements you may not have even heard of! Explore the science of the smartphone with a lesson from the Reactions playlist. The instructor explains the location and purpose of the many different elements that...

Why do metals rust differently? Scholars experiment with metal combinations in a hands-on activity. They create unique environments with different metals and compare the rate and amount of rust for each.
