This is an example of one of the graphs that are created for students to use to analyze their data. They are not limited to bar graphs. Depending in the experiment being conducted, line graphs and circle graphs can also be developed. This one compares the amount of water given to plants and how it relates to the plants height over 50 days. In this Gizmo, the students could manipulate several variables including: the amount of water, amount of light, type of soil medium, and the type of seed planted. For each variable that is adjusted, the students will produce a different set of data.
