This is an activity about satellite size. Learners will calculate the volume of the IMAGE (Imager for Magnetopause-to-Aurora Global Exploration) satellite, the first satellite mission to image the Earth's magnetosphere. They will then determine the... (View More) effect of doubling and tripling the satellite dimensions on the satellite's mass and cost. This is the first activity in the Solar Storms and You: Exploring Satellite Design educator guide. (View Less)

This is an activity about using large numbers in astronomy. Learners will first estimate how long it would take to count to a billion, if it was a full-time job. Then, they will judge their estimates using a calculator to get a more definitive... (View More) answer. Finally, they will calculate the time or speed needed to travel to the star, Proxima Centauri. This is Activity M-7 of Universe at Your Fingertips 2.0: A Collection of Activities and Resources for Teaching Astronomy DVD-ROM, which is available for purchase. (View Less)

This is an activity about interpretation of a data graph. Learners will use mathematics to create a pie chart of percentages and answer accompanying questions. This is the fourth activity in the Solar Storms and You: Exploring Satellite Design... (View More) educator guide. (View Less)

This math problem demonstrates the concept of geometric progression, through an example of a million dollar contract between an employee and an employer. Application of the concept of geometric progression to social cause activism is addressed. This...

In the state of Maryland, a local politician once claimed that sea level is rising because there are too many people putting boats on the open ocean. Could that result in a significant sea level rise, perhaps even destroy low-lying nations such as... (View More) Bangladesh? This resource explores the principle of buoyancy, and is part of PUMAS - Practical Uses of Math and Science - a collection of brief examples created by scientists and engineers showing how math and science topics taught in K-12 classes have real world applications.

Some simple arithmetic can help put the quantity of fuel in a potential oil spill - in this case 400,000 gallons - in perspective. In this example, students calculate the area that would be covered by oil from the volume measurement. This resource...
