Earth’s oceans are a carbon sink, which is a place where carbon is stored long term. Oceans absorb carbon dioxide from the atmosphere. It reacts with seawater, creating carbonic acid, which in turn lowers the pH of the ocean. This phenomena is known as ocean acidification. It will only get
Students often struggle to understand what aquifers are and how they work. Since they are located underground we can’t see them, so it can be hard to visualize in our minds what they look like. In this quick video you can see how I built a model of an aquifer.
The water cycle is taught starting in elementary school. It seems like in high school biology when I get to the biogeochemical cycles (water, carbon, nitrogen, and phosphorus) the water cycle gets glossed over because we assume the students know it and it’s too basic. But water is vital to
At the end of every school year we end our life science curriculum with geologic time. It’s one of my favorite units because I get to bust out my fossil collection (If you know me, that’s a big deal). It’s hard to talk about geologic time, mass extinctions, and evolution
