In a previous post, I explained that a discrepant event is an event that puzzles students because it is contrary to what they would expect to happen based upon their background knowledge.

I showed this to my students which led to a discussion of tipping point and center of gravity.

Then Mrs. Dickey sent this photo, taken in her first grade classroom, to me the next day. Glancy got it! 🙂

First grade environmentalists pledge to “go green” and put less trash in landfills! Three great ways that we can all reduce waste and protect our environment is to reduce, reuse, and recycle. We brainstormed ways to reuse items that we often throw away, as well as ideas to decrease the amount of trash we produce. Then we sorted a pile of trash into five groups: plastic, paper, metal, glass, and those items that must go in a landfill.

We have a new landfill to observe in our classroom. Are these items biodegradable. How long will it take for each to decompose?
