Learners will measure the diameter of a solar flare by making calculations using transparency grids overlaid on images of the Sun. This is the third activity in the lesson "How Does HESSI Take a Picture?" NOTE: The HESSI mission was renamed... (View More) after Dr. Reuven Ramaty, who was the original Co-Investigator for this NASA mission, and was a pioneer in the fields of solar physics, gamma-ray astronomy, nuclear astrophysics, and cosmic rays.

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)

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)

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)

This activity is about planetary distances. Learners will create a model of the solar system using beads and string, and compare planetary sizes using common types of fruit and seeds. The lesson models scientific inquiry using the 5E instructional... (View More)

This resource introduces the concept of wind chill, the formula used to measure it and relates it to the causes of hypothermia. A simple experiment using a pie pan, sand, fan and a thermometer demonstrates this concept. The resource is from PUMAS -... (View More)
