Brainy Briny Elementary: What Eats Light? (Grades K-5)
A full week of standards aligned elementary science, built around the Brainy Briny's Elementary Kit. Three sealed bags sit in the window. One grows a radish, one grows algae, and one grows algae with brine shrimp grazing on it. By Friday they look nothing alike, and the students measure the difference themselves rather than being told about it.
Everything below is free to download and free to use in your classroom. Two versions, one for the little ones and one for upper elementary. The Administrator Package is the one to hand your principal, because it lists exactly which NGSS, Florida and Texas standards the week covers, and it is honest about which ones are a full match and which are a stretch.
