Spectra's Current Crisis

Terminal Twins

Registration is now open for this year’s PhysicsQuest, Spectra’s Current Crisis!

Register now for a FREE kit for this year’s PhysicsQuest, Spectra’s Current Crisis. 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. They aren’t your ordinary sheisters, they have sub-atomic superpowers. Your students can help Spectra and her crew put a stop to 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. Register now for your FREE PhysicsQuest kit!

We will be sending out the Spectra’s Current Crisis kits (for free) in late January. 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.
