Rivers and lakes would freeze from the bottom up instead of on the surface and all the species that live within those aquatic biomes would now be exposed to cold from the ice below and the cold air above. It is unlikely that those species would not be able to survive. Fortunately, we

Roller coasters are a fantastic tool to teach about forces and motion. All of my students have either ridden on or at a minimum seen a roller coaster in action. YouTube is filled with videos of roller coaster rides to use as anchoring phenomena. This year, I used half a semester with roller coasters as my anchor and I could have continued the development further. Some of the concepts that can be covered with Roller Coasters include: Newton's Laws of Motion The First Law of Th
