This is an activity about like and unlike charges. Learners will use plastic tape strips to investigate how charges interact. This is the second activity as part of the iMAGiNETICspace: Where Imagination, Magnetism, and Space Collide educator's... (View More) guide and student guide.

In this activity, learners draw a circle with a single focus, an ellipse with two foci close together, and an ellipse with two foci far apart, and compare the shapes. Learners then measure the Sun in four images each taken in a different season,... (View More) comparing the apparent size of the Sun in each image to determine when Earth is closest to the Sun. This is the second activity in the SDO Secondary Learning Unit. The activity is reprinted with permission from the Great Explorations in Math and Science (GEMS). (View Less)

One particular type of domino game, sometimes called the All Fives Domino game, uses multiples of five in order to score points. It can be the basis for a number of games designed to develop conceptual understanding of multiples of numbers through...

This is an activity about the movement, or "wandering," of our Earth's magnetic poles. The learner will explore this concept by measuring and calculating the distance the Earth's north magnetic pole has moved over the past 400 years and calculating... (View More) the rate at which the magnetic pole location has changed its position during that time. Finally, learners will use this information to extrapolate how the region for viewing aurorae may change over the next century at the present rate of polar wander. This is Activity 6 in the Exploring Magnetism on Earth teachers guide. (View Less)

In this activity, students learn about the motion of the Sun in relation to the Earth, and how geographic directions are defined. Students use a tetherball pole (or an alternative) as a gnomon and the shadow the Sun casts to determine the exact... (View More) directions of north, south, east and west. The best tetherball pole to use is one that is in full sunlight for most of the day, one that is vertical and unbent, and one that is built on asphalt or concrete. This activity can be done as a whole class or individual project. Part 1 of this activity involves the initial marking of the tetherball pole shadow using chalk (about 10 minutes) and subsequent markings by one or two students (less than 5 minutes) every half hour over a four-hour period. Students keep a record of the gnomon’s shadow by recording a sketch in their logs. Part 2 of this activity involves using a piece of string to connect the dots after the final observation, then bisecting this arc to determine north and south. The lesson includes discussion questions, background information about gnomons, and a math extension activity making and graphing the tetherball's shadow length at different times. This activity is the fifth lesson in the Ancient Eyes Look to the Skies curriculum guide. (View Less)

In this activity, students use base-two slide rules, log tapes, and calculators to practice raising exponents in base notation and pulling down exponents in log notation. Students will develop an understanding that antilog notation expresses the... (View More) exact same idea as raising a base to a power. This activity is activity C2 in the "Far Out Math" educator's guide. Lessons in the guide include activities in which students measure, compare quantities as orders of magnitude, become familiar with scientific notation, and develop an understanding of exponents and logarithms using examples from NASA's GLAST mission. These are skills needed to understand the very large and very small quantities characteristic of astronomical observations. Note: In 2008, GLAST was renamed Fermi, for the physicist Enrico Fermi.

In this activity students develop a simplified log table using information from their Log Tapes. Then they use it to solve arithmetic problems by looking up and combining logs, and finding the antilog. Because these problems are extremely simple,... (View More) students appreciate the logic of logarithms without getting bogged down in the arithmetic detail and error. This is activity B3 in the "Far Out Math" educator's guide. Lessons in the guide include activities in which students measure,compare quantities as orders of magnitude, become familiar with scientific notation, and develop an understanding of exponents and logarithms using examples from NASA's GLAST mission. These are skills needed to understand the very large and very small quantities characteristic of astronomical observations. Note: In 2008, GLAST was renamed Fermi, for the physicist Enrico Fermi.

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) required to accomplish a specific task. Additional resources and an extension to this activity are available.

This example explains how contour mapping teaches both estimation and spatial visualization skills. To have experience visualizing 3-dimensional fields from a 2-dimensional map helps students throughout their mathematical career. This resource is...

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) student data sheet.
