Today we talked about some of the tools that we will use to collect data about our local ecosystems. The barometer, the Kestrel (wind meter), and the sling psychrometer are tools for studying the weather. We will use these tools, and others, when we work to analyze our local ecosystem and work to discover the problems that exist there.

Today we discussed the carbon cycle, which is the way that carbon gets moved through our environment. Carbon is essential to life on Earth and is a key component to proteins, fats, and carbohydrates. The carbon cycle is a model that scientists have created to show how carbon gets transferred between the atmosphere, land, water, and organisms. When you eat a living organisms (whether it is a buffalo or a carrot) you are adding to the carbon cycle.
