Tuesday, September 01, 2015
Like sailors putting a finger to the wind, migrating moths check the atmospheric conditions around them and adjust their headings accordingly, a new study finds. They do it by sensing turbulence, which helps them determine whether the wind is blowing the... more

Spectra: High Intensity

Ms Alignment

I hope you are having a great time doing the activities for Spectra's High Intensity, you can submit your answers here. You do not have to have completed all the activities to submit your answer. If you've only had time to do a few or only one activity you can still submit answers and be eligible to win fabulous prizes! 

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.

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