So we figured out that there is indeed light we cannot see. This light behaves the same as visible light, reflecting off of various surfaces, transmitting through others, and absorbing into even others.
With this, we recognize that our sense of hearing is like our sense of sight in that there are sounds we can't here, as seen in using this tone generator.

We also saw Mrs. Brinza use a tuning fork (which we could hear) create waves in a tub of water...and this got us thinking that maybe we could represent light as waves. If waves carried a different amount of of energy than our eyes or ears couldn't register, then this made sense to revise our model. We also used this wave simulator to better understand this!
We recognized that light may have a higher or lower frequency which are eyes are designed to detect. And that allowed us to better understand the electromagnetic spectrum, which contains visible light, along with the infrared light that comes out of the remote! We also learned about other wavelengths of radiation that carry more or less energy!
