This story can be used to teach that results must be checked against known facts to see if they're reasonable. It is designed as a follow up to "The Fall of the Ruler." This resource is from PUMAS - Practical Uses of Math and Science - a collection... (View More)

Keywords: Reaction times
Audience: High school
Materials Cost: Free per student

This activity shows how an ordinary ruler can measure human reaction time (RT). Learners will convert a standard ruler into a time ruler (relating time and distance) and measure each others RT. They will also calculate means and variances and the RT... (View More)

This article explores how statistics can be interpreted in different ways to yield different conclusions. It describes the outcome and discussion of two class activities. In the first, the results are interpreted to "show" that taking a group rather... (View More)

This is a brief activity about the mathematics of Mars. By playing this matching card game, learners will gain knowledge of Mars mathematical facts and vocabulary.

This is an activity about planetary sizes and distances. Learners will construct a scale model of the Earth, Earth’s Moon and Mars in relation to each other using balloons. They will use this model to predict distances and reflect on how... (View More)

In this activity, students learn that probability is a way of measuring the chance of something happening. Students make predictions and match predictions with data, using a "probability tester" made from two golf tees. The activity includes a... (View More)

Students build a simple aneroid barometer that can be used to measure changes in air pressure. Materials required include a large jar, ruler, large balloon, 2 drinking straws, and clay. The instrument is used to track changes in air pressure, and... (View More)
