As you move through the Carbon Cycle lab, you will see how carbon moves through the different ‘spheres’ into which scientists divide the planet: the biosphere (global set of ecosystems where living things are found), the lithosphere (the rocky upper layers of the Earth), the hydrosphere (combination of all sources of water on under and over the Earth’s surface), and the atmosphere (layers of gases above the Earth). In any matter cycle, the substance at the heart of that cycle (e.g., water, nitrogen, and carbon) is converted to different physical and chemical forms and moved from one part of the Earth to another. This is a more open- ended question where we will be more interested in the ideas that you propose and the justification (‘I think this because. There is not one certain answer to a question of this type. A question like this will ask you to speculate about why something is the way it is, for instance. Hypothesis-based question → This will be a question which will require you to stretch your mind little bit. There is still an expectation that your answer will match up to a certain response, but you should feel comfortable in expressing your understanding of how these different ideas fit together. Synthesis-based question → This will be a question that will require you to pull together ideas from different places in order to give a complete answer.
There is more of an expectation of you providing a certain answer for a question of this type as compared to questions of the other types. That answer will be based on information (1) presented by your instructor, (2) found in background sections, or (3) determined by you from data, graphs, pictures, etc. Those questions will come in three different varieties:įact-based question →This will be a question with a rather clear-cut answer.
Throughout this lab you will be asked to answer some questions. That is because the lab also is focused on how human activity can influence those processes – and potentially influence the weather and climate on the planet. This lab is concerned with the different processes comprising the carbon cycle, but its importance goes beyond just becoming familiar with the various ways that carbon is transformed and transported around the globe. As you have hopefully deduced by looking at the title of the lab, the name of the cycle is the carbon cycle. Carbon is constantly being moved around the Earth through the processes that make up the Carbon Cycle. You will see in later labs just how important this relatively small concentration of CO 2 is with expect to Earth’s energy balance, but for now we need to focus on the cycle in which atmospheric CO 2 is involved. You learned in the troposphere lab that carbon dioxide (CO 2) makes up about 0.04% of the atmosphere.
This lab has 25 short-answer questions you will answer prior to the three big questions (i.e., research questions) Mila has noted above.

Mila is going to introduce the carbon cycle, show you how to use Google Earth in this lab, and then end her video by reminding you of the three main questions you should be able to answer at the end of the lab. Before beginning the lab, please watch the short video below.
