Interactions of Energy and Matter: Dawn Instrumentation

Become a crime scene investigator! Learners model Dawn Mission scientists, engineers, and technologists and how they use instrumentation to detect distant worlds.

Earth, the Universe, and Culture

This lesson will help students understand the cultural nature of scientific research. Students explore famous scientists, their theories, places of origin, and their culture.

Density: Sea Water Mixing and Sinking

These two hands-on labs are about the role of temperature and salinity in governing the density of seawater, a major factor controlling the ocean's vertical movements and layered circulation.

Astro101 Slide Set: "Inside-Out" Star Clusters

This slide set focuses on the discovery that some infant stars on the edges of star clusters are older than similar stars in the centers, a finding of NASA's Chandra and Spitzer missions.

Technology Teacher: Keeping Nine Eyes on the Weather

This article discusses how the Multi-angle Imaging SpectroRadiometer (MISR) instrument found on the Terra satellite is used to understand how particles in the atmosphere interact with sunlight and how particle pollution affects Earth's climate.

What's the Matter?

In this lesson, students will explore the density of substances as a model for understanding the mass to light ratio as a predictor of dark matter. They will measure and calculate mass and volume to calculate the density of a foam ball.

How Far? How Powerful?

Gamma-ray bursts are distant explosions that briefly outshine the rest of the gamma-ray universe. In this lesson, students will follow the same procedures used by today's astronomers to determine two basic facts about gamma-ray bursts: their distance from Earth and their power.

Postcards from Space

This is an activity about boundaries. Participants will imagine they have taken a journey from Earth through the Solar System out into the Milky Way Galaxy.

Grandpa's Social Security

This simple example shows how algebra can be useful in the real world by exploring the question: Should Grandpa start receiving his Social Security benefits at age 62 or should he wait until age 65?

Using Mathematical Models to Investigate Planetary Habitability: Activity C The Role of Actual Data in Mathematical Models

Students explore how mathematical descriptions of the physical environment can be fine-tuned through testing using data. In this activity, student teams obtain satellite data measuring the Earth's albedo, and then input this data into a spreadsheet-based radiation balance model, GEEBITT.
