A line plot may not be a useful graph for investigating variation so we must come up with a new representation based on groups of data. Construct a stem and leaf plot from a set of 26 data values.

Discover how to use stem-and-leaf plots and box-and-whisker plots to visualize data by taking a look at examples and a video lesson.

The Advanced Data Grapher can be used to analyze data with box plots, bubble graphs, scatterplots, histograms, and stem-and-leaf plots.

In this activity, you will be able to observe the oxygen production in leaves by doing a floating leaf disk experiment. You can also find out how quickly plants produce oxygen, and what variables affect photosynthesis.

Students take apart and label basic parts of a plant in this lesson plan. The students also use kitchen spices to determine which part of a plant was used for various flavorings.

Students conduct a simple experiment to model and explore the harmful effects of acid rain (vinegar) on living (green leaf and eggshell) and non-living (paper clip) objects.
