# Investigating the Ring Current

Students will explore Earth's magnetic field using a dipole magnet and compass, and then build a model of Earth's ring current and use it to observe a magnetic field’s response to a fluctuating electric current in this hands-on investigation of... (View More)

Keywords: Magnetism
Audience: High school
Materials Cost: \$5 - \$10 per group of students

# Sounds of the Sun

This is an activity about the Doppler effect. Learners begin by simulating the noise made by a passing siren. After learning that the change in pitch results from movement, they investigate the definition of frequency, calculate change in frequency,... (View More)

# Induction in an Aluminum Can

This activity demonstrates Lenz's Law, which states that an induced electromotive force generates a current that induces a counter magnetic field that opposes the magnetic field generating the current. In the demonstration, an empty aluminum can... (View More)

Keywords: Magnetism; Lenz's Law
Audience: High school
Materials Cost: \$1 - \$5 per group of students

# Iron Filings and (2-3D) Magnetic Field Lines

This is a lesson to demonstrate magnetic field lines in 2- and 3-dimensions. In the first activity, learners sprinkle iron filings over a magnet underneath a paper and record their observations. The second activity involves building a 3-D magnetic... (View More)

# Wavelength and Energy

This is an activity about wavelength and frequency. Using a 30 to 50 foot rope and two volunteers, learners will observe as one end of the rope is shaken and wavelength patterns are created. They will estimate the wavelength, the distance between... (View More)

# Science Exploration: Sizing Up the Stars

This is an activity about size, distance, and perspective. Learners will observe two objects of the same size placed at different distances, and they will observe two objects of different size placed at varying distances. This concept is then... (View More)

Audience: Elementary school

# Science Exploration: A Rainbow Connection

This is an activity about light and its component colors. Learners will observe a photograph of a rainbow and make observations about what they see in the photo. Next, they will observe a rainbow spectrum and draw the rainbow using crayons. Finally,... (View More)
