This is an activity about the Aurora Borealis or Northern Lights. Learners will plot the Auroral Oval in the northern hemisphere and determine the height of the northern lights using Carl Stormer's triangulation method. This activity corresponds to... (View More)

Problem: How do you measure an angle with a protector, when that angle is between two solid walls? This resource is from PUMAS - Practical Uses of Math and Science - a collection of brief examples created by scientists and engineers showing how math... (View More)

This kinesthetic activity simulates the process of evolution by natural selection. Students take on the roles of crab-like predators that exhibit one of four variants of feeding appendage: a spoon, fork, knife, and chopsticks. The simulation runs... (View More)

This is an activity about observing the Sun. Learners will construct a pinhole projector to project an image of the Sun, observe and record the size of the projected image, and calculate the diameter of the Sun using the measurements and a known... (View More)

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 is an activity about determining the distance of a solar flare from the center of the Sun's disk. Learners will use transparency grids overlaid on images of the Sun in order to calculate the distance of a solar flare, similar to a signal... (View More)

Water supply in the Southwestern United States depends on snow. Students discover its importance through analysis and evaluation of data, satellite images, space shuttle photos, and ground-based observations, and then apply their findings in a... (View More)

Students confront the challenge of improving global agricultural production in order to feed increasingly larger populations. Students evaluate tables, maps, graphs, photos and satellite images detailing global population growth patterns and... (View More)

Learners will use balloons to construct a scale model of the Earth, Earth's Moon and Mars in relation to each other. They will use this model to predict distances and reflect on how scientists use models to construct explanations through the... (View More)

Learners will create a model of the solar system using colored beads and string. In addition, learners will compare planetary sizes using common types of fruits and seeds(either actual fruits or the accompanying drawings of fruits). The lesson... (View More)
