We are still reviewing what we have learned about the properties of light when it comes into contact with matter.  It can be reflected, refracted (bent or split, depending on the density and composition of the matter), and absorbed.  Today's activity involved light being split into its seven individual colors of the spectrum (diffraction).
Picture
We did an experiment where each student was given a flashlight and a small equilateral triangle prism.  By shining the flashlight through the prism as the correct angle (you need to experiment), the prism separates (diffracts) the white light into the seven different colors of the spectrum (red, orange, yellow, green, blue, indigo, and violet).
I also did a brief demonstration of the primary colors of light.  Unlike with pigmentation, the primary colors of light are red, blue, and green.
Then we did a brief mini-lesson on conjunctions and how they are used to link together different parts of a sentence.  I figured that you can't beat the classics:
Then, I allowed the students to continue with their posters.  They do need to finish it tomorrow so I will allow a reasonable amount of time tomorrow. 

Lastly, the quiz is next Thursday.  It will consist of ten multiple choice questions.  I am pretty confident about how well the students will do but I will still review.  I am planning on having a Kahoot! review on Wednesday though it will be much more extensive.
