Worldwide patterns and sources of aerosols are analyzed and evaluated for potential hazards to aircraft safety. Using aerosol index maps created from data gathered by the TOMS instrument, student groups will analyze and compare aerosol data from... (View More)

In this activity, students learn that the small droplet size of water the in the clouds and wind contribute to clouds remaining suspended in the sky. The demonstration requires a clear beaker, sand, and rocks. Several other activities are suggested.... (View More)

This is an activity about identifying and comparing the Earth’s seasons. Learners will write paragraphs depicting scenes or events that have recognizable season-related elements, without revealing the intended name. The group will then play a game... (View More)

This is an activity about understanding how the Earth’s axial tilt changes the angle at which sunlight hits the Earth, contributing to the variations in temperature throughout the seasons. Learners will create a sun angle analyzer in order to see... (View More)

This is an activity about the shape of the Earth’s orbit. Learners will first use elements of the orbit of Earth and Pluto and an apparatus using string, a pencil, and pushpins to accurately draw an ellipse, showing the nearly circular shape of... (View More)

This is an activity about the size and scale of the Sun-Earth system. Learners will take an imaginary trip to the Sun by comparing images of the Sun and Earth at different points in altitude above the Earth. This is to ultimately conceptualize the... (View More)

This is a lesson about the role of robots in space exploration. Learners will examine their prior notions of robots and then consider the characteristics and capabilities of a robot, like the Cassini-Huygens spacecraft, that would be sent into space... (View More)

In this lesson, learners will use History of Discovery cards and interpretive skits to examine how scientists throughout history have explored Saturn. The lesson enables students to discern the multicultural nature of scientific inquiry and to see... (View More)

This is an activity about gravity. Learners will design their own experiments to explore the fundamental force of gravity and then extend their thinking to how gravity acts to keep objects like moons and ring particles in orbit. They use the... (View More)

In this activity, students become familiar with the orientation of shadows, their size in relation to the object casting them, and how the alignment of the Sun, the object, and the shadow tells us much about how shadows work. Supplies needed for... (View More)
