Sorry for the double post, but I'm also confused about one other thing. When you put images for an order, class, or family, which species do you choose images of? Or do you just search, for example, alligators, alligator eggs, etc?
Two years ago I knew stuff about rocks, minerals, experiments, and ecosystems, yay!
Last year I knew stuff about amphibians, reptiles, water, and more experiments, yay again!
Now I'm learning stuff about oceanography, fossils, and writing/following instructions, yay for the third time!
