Emerging electricians build a simple ammeter for making measurements on an electric current. They test the placement of solar cells in both series and parallel circuits and examine the magnetic field produced by the movement of electrons...

Can you infer the wiring diagram of a series of lights based on their behavior alone? Scholars work with multiple boxes of four lights. They must flip the switch and decide how the lights are wired. By applying their knowledge of...

Earth's systems respond to changes in environments in all types of ways including migration, extinction, adaptation, immigration, and emigration to name a few. Part one in a series of seven is a pre-test consisting of 14 questions. Some...

How has Earth changed over time? Pupils explore the topic in a differentiated instruction unit on the geological time scale. After a pre-assessment to gauge knowledge, class members divide into groups based on their ability levels and...

The final lesson plan in the 21-part series on climate change focuses on energy solutions to the consumption problem. Using data specific to their school, pupils make recommendations, follow up on actions, and carefully track...

Your eyes each work independently, so how do we only see one image? The quick hands-on experiment encourages young scientists to test their blind spots on each eye individually. After learning where the blind spot is and why it exists,...

Write, edit, and then revise! The fourth lesson in a five-part series asks peers to provide feedback on research. Individuals then use the research to edit and revise conclusions and develop their presentations.

You don't have to be a scientist or even out of high school to contribute to scientific research. In the 12th lesson in the series of 21, scholars use this opportunity to add to the growing body of scientific knowledge and consider the...

Before determining which electrons are available for reactions, scientists identify each atom's electron configuration. An informative video from Socratica's chemistry playlist includes how to write electron configurations. It explains...

Better than some television series, parallel series circuits provide practice for calculations. Scholars work through a series of problems, each progressively more difficult. They apply knowledge of voltage calculations, resistors, and...
