KLRN Virtual Classroom - Magnetism
Extend the learning (and fun!) with these resources about MAGNETISM … and more from PBS LearningMedia!
And, be sure to join us on February 3 @ 11am & 3:30pm CST for our next KLRN Virtual Classroom. We'll watch the Curious Crew take on THERMAL ENERGY!

Collection Jar | Sid the Science Kid: Games
Sort items with this fun activity. Discover which items are magnetic and take an up close look at all the items.
Inspector Detector Challenge
Kids design and build magnetic-field detectors and use them to find hidden magnets in this activity from Design Squad Nation. They also learn how NASA uses magnetometers to learn what is going on inside a planet or moon. People love treasure hunts. But, in this one, kids are looking for something invisible! As they build their magnetic detectors, the kids use the engineering design process, apply a variety of science concepts (e.g., force, magnetic fields, mapping), and learn how a planet's or moon's magnetic field gives NASA scientists insights into its structure and how it formed.

Fun With Magnets
In this video, watch as children perform a quick and easy magnetic test. Fun With Magnets is a hands-on science exploration for young children and their teachers, parents or caregivers.
The Sun — Earth's main source of energy — appears to shine at a constant rate. However, the Sun's magnetic field is actually constantly changing, and this affects its energy output. These variations cause effects that extend throughout the solar system. In this video segment adapted from NOVA, learn about some of the effects that solar activity may have on Earth.
4 Odd Things We've Seen in Your Brain | BrainCraft
In this episode, we look at magnetic resonance imaging (MRI), and functional magnetic resonance imaging (fMRI), and what those tests reveal. Sometimes things get a little weird in fMRI machines.
In this video excerpt from NOVA’s "Making Stuff: Smaller", host and New York Times technology columnist David Pogue visits the Institute of Robotics at ETH Zurich, where materials scientists are designing a microbot—about the width of a strand of hair—that can travel into a human eye to treat a type of blindness. The microbot is controlled by an externally generated electromagnetic field, eliminating the need for bulky mechanical parts. In a related activity, students learn about magnets and their properties while designing their own model of a small magnet-powered robot. Students also see howmaterials scientists use design ideas from nature to overcome weird forces that microbots encounter. Student Activity
