Spectra: High Intensity

Ms Alignment

Registration is back online for PhysicsQuest. Please click here to sign up!

Miss Alignment has broken out of jail and is on the loose hatching evil plans. Armed with a high IQ, an inferiority complex, and a secret lair, she will try yet again to control the town. Your students can help Spectra, her gang, and her new friend the Quantum Mechanic stop Miss Alignment’s focus on evil.

In celebration of the International Year of Light, this kit will have all of the equipment needed to teach students about bending light, spherical lenses, how color and energy are related, and how the sun’s light also carries heat. As the students do these activities, they will be applying all the skills they need to help our superheroes prevent Miss Alignment’s attempted town domination.

We will be sending out the Spectra: High Intensity kits (for free) in early January. If you would like to purchase last year’s kit, Spectra’s Quantum Leap, please visit our online store.

Answers and Winners of Spectra’s Quantum Leap can be found here.

For more information about the overall program, please visit the PhysicsQuest About Page.
