I’m thankful that my school board has paid for licenses with Explore Learning.
Last night, I found this great lab for any optics unit; it comes with free worksheets and answer keys. Both Secondary 3 classes had fun exploring additive colours and tweaking the RGB factors to make cool colours.
We figured out the RGB factors for pumpkin orange, royal purple and baby blue!
I also reposted this on Facebook so that other teachers could use it too.
