PhysicsQuest

Spectra's Current Crisis

Terminal Twins

This year's edition of PhysicsQuest has shipped—enjoy your kits!

With Miss Alignment in jail, Lucy’s town assumes things have gone back to normal, but they would be wrong. Taking advantage of the now-abandoned Con Cave and a trusting town are twins Andy and Cat Terminal. Your students can help Spectra and her crew stop the Terminal Twins from negatively affecting the town. As students help Spectra defeat the Twins they will learn about current, circuits, motors, and colors. This is a kit you positively can’t resist! 

Unfortunately, all the free kits for this year have been claimed and shipped; if you didn't get one, you can download the teacher's manual for free here and use it to create your own!

If you would like to purchase past PhysicsQuest kits, that can be done here. If you'd like to download past manuals or comics and create your own kits, that can be done through links on the About PhysicsQuest page.
