Mapping the Field of Multiple Dipole Magnets
So you built a magnetometer, now what? High school scientists use their magnetometer made in a previous lesson to map the union of magnetic fields of dipole magnets. They experiment with different alignments and draw conclusions about...
PHET
Mapping the Ambient Magnetic Field
No GPS allowed! High school scientists continue to explore magnetic fields with a hands-on activity. After mapping the ambient magnetic field in the classroom and completing data analysis, they write about the similarities and...

Learning about Space Weather
Is the sun the only celestial body with magnetic fields? A guided discussion on the weather in space is designed with a mix of questions, discussions, explanations, and applications. Additionally, the resouce includes an article for...
PHET
CME Plotting
Young scientists build on their previous knowledge and apply it to coronal mass ejections. By plotting the path of two different coronal mass ejections, they develop an understanding of why most don't collide with Earth.

The Dynamic Nature of the Sun
In this second lesson of the series, pupils learn to observe similarities and differences in photos of the sun and record them in a Venn diagram. Then, small groups practice the same skill on unique images before presenting their...
PHET
Features of the Sun
There are so many things to discover about the sun! Pupils discuss their knowledge of the sun, explore its features, apply their knowledge by labeling photographs, and then reflect on their learning by working in groups to draw and label...

The Earth as a Magnet
Everyone loves playing with magnets and iron filings. Here, young scientists first observe and then participate in an activity demonstrating magnetic fields. After completing their observations, they apply this knowledge to...
PHET
Iron Filings and Magnetic Field Lines
How do magnetic fields differ? Allow scholars to see the difference between 2-D and 3-D magnetic fields. They construct models of both and observe how they are similar and different. It is the fifth installment of an 18-part unit.

Explore the connection of surface area to bonding within atoms. Learners complete lab investigations to model changing surface area with different sizes and concentrations of atoms. A flour fireball demonstration follows the labs to...
Cornell University
Unknown Powders
Create a little scientific magic within your classroom! Learners mix powders and liquids and identify chemical reactions. Based on the reactions, individuals determine the identity of various powders.
Cornell University
What Is Rust?
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.
Cornell University
Electromagnets
Discover the connection between electric current and magnets. Scholars create electromagnets by passing a magnet through a coil. They experiment with different materials to determine the variables that affect the strength of the current.
Cornell University
Light Waves: Grades 9-12
Explore the behavior of light waves with a lab activity. Scholars build new vocabulary through experimentation and observation. Using different mediums, they model reflection, refraction, transmission, diffusion, and scattering of light.
