Our seventh grade has been studying the Law of Conservation of Energy and energy transfers. This week they will be challenged to make their own Rube Goldberg Machine, which features energy transformations. Check back in a few weeks to see photos of some of our machines!
Until then, check out these videos about Rube Goldberg Machines:

What a great day to be a Tiger! The Circleville HS football team will be playing in their first game of the playoffs this Friday, so to wish these students luck their convoy of police cars, firetrucks, and other supporters paraded past each of the school buildings within our district. It was awesome to see my past students' faces lit up with excitement as they experienced all the students and staff cheering for them. Best of luck this evening!

A local Pickaway County farmer wants to create a 3-acre, clay-lined, sludge lagoon on his property within a mile of several housing developments and two schools. Neighbors met at the local middle school last night to voice their concerns about this project.
This relates to our seventh grade science curriculum in several ways:
- Nitrogen Cycle - farmers use the waste of humans and animals to enrich their farmland by spraying the composted waste onto their crops to increase yields.
- Food Web - the waste in the sludge lagoon is decomposing with the help of bacteria; however, some of the waste will still be locked up into an unusable form for longer than it should by being concentrated in one area.
- Matter - How would you classify the substance of human sludge, animal waste, and partially digested foods? Would this be a pure or unpure substance? If it's unpure, what kind of mixture would this be - heterogeneous or homogeneous?
- Periodic Table - The gases that would be released through the decomposition of the matter include elements that will be studied through the periodic table. The gases include, for example, hydrogen sulfide (H2S), methane (CH4), carbon dioxide (CO2), and ammonia (NH3).
- Water Cycle and Watersheds: How would a leaking sludge lagoon affect the water table in this community? Which watershed would a flooding sewage lagoon affect in Central Ohio?
