Whatever floats your boat. Young engineers learn about density by measuring the masses and volumes of boxes filled with different materials. Using their knowledge of densities, they hypothesize whether objects with given densities will...

Slide the class into a skewed view. Learners alter the location of the median relative to the mean of a normal curve to create a skew distribution. They compare the curve to a histogram distribution with the same skewness. 

Does the size of the bin matter? The resource allows pupils to explore the relationship between the normal curve and histograms. Learners view histograms compared to a normal curve with a set standard deviation. Using the interactive,...

There is often more to data than meets the eye. Scholars learn that they need to analyze data before making conclusions as they look at data that describes the number of candy bars boys and girls eat. They disprove a given conclusion and...

You may have many ideas, but asking the public what they want is probably the best approach. Learners act as the student council president and conduct a survey to determine the needs of the school. They then analyze the data using...

With rising oil prices and increasing concerns over global warming, the pressure is on for engineers to develop alternative sources of energy. Among the new technologies being developed are hydrogen fuel cells, which young scientists...

With so many types of graphs, don't let your learners get stuck figuring out which one to use. To track how Zoe spent her allowance, use this interactive lesson to review all the types of graphs and pick the best one to display the data....

Class members explore how to read and use histograms by watching a video on creating and analyzing histograms. To finish, the class works on a set of questions that tests these skills.

Pairs work together to determine whether unknown solutions are either acids or bases by using a red cabbage indicator solution. After determining the general pH of the unknown solution, classmates blow into the same indicator after...

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

Explains how to construct a simple box-and-whisker plot, and demonstrates the steps. Discusses quartiles and medians, shows how to find them, and explains how they relate to box-and-whisker plots.

Explains how to create a stem-and-leaf plot from a data set. Demonstrates how to format a clear stem-and-leaf plot.
