Journaling

Audio speakers, hard drives, credit cards, and even the earth use magnetic fields. While we observe the effect of magnetic fields, we can't actually see them. A viewer helps participants explore magnetic fields, some of the items that...

Help your classes visualize the invisible. The 26th episode in a Crash Course physics playlist highlights the fields created by charged particles. Using examples and diagrams, the presentation demonstrates the magnitude and direction of...

Recording scientific evidence allows for important discoveries and conclusions. A remote learning resource outlines how to create a field journal to record scientific observations. The outline resource includes notation about the...

Want to add a wow factor to your current chemical changes lesson plan? Try a microscale experiment with colorful precipitates! Partnered learners conduct 10 single displacement reactions and record their observations.

Class members use a compass and several points to map out the magnetic field of a magnet. Pairs trace the magnetic field lines produced by a permanent magnet by positioning the compass in numerous spots around the magnet to view the...

Young scientists begin a field journal by following four steps. A real-world example of an entry showcases the different parts, including location, date, drawings, and more. 

How did Rutherford determine that the nucleus was the center of an atom? Take a look inside the famous Gold Foil Experiment with an interesting interactive. Learners fire a beam of alpha particles at a nucleus containing variable...

Magnetic fields might not be a field of dreams but they are useful. Class members observe the reactions of magnetic fields using a compass, iron filings in a paper container, and iron filings suspended in mineral oil. 

An MRI uses both a magnetic and electricity, so how do the two interact with each other? Class members observe the effects on a charged particle when it is subject to both an electrical and magnetic field. The teacher background...

One acre of land can contain more than a million earthworms. Scholars collect earthworms to observe their movements. Once placed on paper, the sound of movement often fascinates pupils. When placed on glass, the earthworm is unable to...
