It might be silly to determine the creep rate of putty but groups will enjoy making different formulations of silly putty and playing with them to understand how the different mixtures behave. The second part of the activity has groups...

Use graphs to interpret life in 136 counties. Pupils analyze histograms and describe the shapes of the distributions of data collected from several counties on different aspects of life. Scholars make predictions on the difference in...

What does stretching a balloon have to do with equilibrium? Groups explore preconditioning by stretching a balloon to a point of equilibrium. They then measure the amount of force required to stretch the balloon to the same point several...

What's the best way to record temperature over a long period of time? Scholars learn about collection of weather and temperature data by building thermistors in the fourth installment of the 10-part Discover Your Changing World series....

Comparing college football teams, Division I is said to have heavier lineman than Division III. Your mathematicians are given data from two different divisions and will have to interpret a dotplot and calculate the difference in weight...

In this activity, students compute statistical measures like the mean, standard deviation, and variance of the data set. They understand how measures of variability can be interpreted.

A series of step-by-step worked problems demonstrating how to take a set of data and produce the variance and standard. Hints are provided along the way and the final measures are shown for the user to check.
