MRC: Overview of the Solar System (Grades 3-5)

This is a lesson about the size and scale of planets in the solar system. Learners will kinesthetically model the order of the planets outward from the sun. Then they will use a string and beads to create a model to represent the relative distances between the planets.

Layer upon Layer

In this hands-on activity, students build a physical model of the atmosphere using paper disks, then use the model to learn the structure of the atmosphere and the scientific terms used to describe the troposphere, stratosphere, mesosphere, thermosphere and exosphere.

The Incredible Two-Inch Universe

In this activity, learners explore the size and scale of the universe by shrinking cosmic scale in 4 steps, zooming out from the realm of the Earth and Moon to the realm of the galaxies. This informational brochure was designed as a follow-up take-home activity for teen and adult audiences.

Finding Impact Craters with Landsat

In this activity, students consider the sudden release of a tremendous amount of kinetic energy when an extraterrestrial object strikes the Earth. In small groups, they study satellite images that show possible evidence of impact events.

How Can You Study Rain?

In this problem-based learning activity, students learn about global precipitation patterns.

Stellar Evolution: Our Cosmic Connection

In this activity, students use multiwavelength images of stars in different stages of evolution to investigate how the initial masses of the protostars determines their evolutionary paths.

SOS Water Falls Pre-Visit

Intended for use prior to viewing the Science on a Sphere film "Water Falls," this lesson introduces students to Earth's water cycle and the importance of freshwater resources.

Climate Kids: Make Seed Paper

The recycled paper produced from the instructions provided contains an additional component - wildflower seeds. The entire paper disc can be planted; the sprouting of the flowers can be observed and analyzed.

The Tools of Gamma Ray Astronomy

NASA scientist, Neil Gehrels, serves as your guide to this online lesson on gamma ray tools, which focuses on advances in detector technologies since the 1980s that have enabled us to capture and image high-energy phenomena. Dr.

The Expanding Universe

This is an activity about the Doppler effect. Learners will use long springs or ropes to examine the frequency and wavelength of various waves.
