This resource has several lessons consisting of short, on grade level readings, followed by questions. I would not use this in entirety but could see me pulling out Lesson 3-1 (What is a Beneficial Insect?), Lesson 3-2 (Predators), Lesson 3-3 (Pollinators) and Lesson 3-4 (Recyclers and Decomposers).
Short and sweet overview of rocks and minerals. I can see the students researching to build a better background of what silicate/non-silicate refers to and then apply that knowledge to sorting minerals. Could be used as Enrichment.
