## 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.

## The Great Planet Adventures Planetarium Show

Developed as a planetarium show, this video describes the unique environment of our solar system planets and a few satellites, along with some of the challenges and possible solutions for potential human habitation on each.

## The Mathematical Implications of Lying

This article explores how statistics can be interpreted in different ways to yield different conclusions. It describes the outcome and discussion of two class activities.

## Explorando mapas de colores: Usando datos de ozono estratosférico

Using the 5E instructional model, students discover the value of using color maps to visualize data. The activity requires students to create a color map of the ozone hole from Dobson data values derived from the Aura satellite.

## MY NASA DATA: El Niño Lesson

The strength of the historic 1997-1999 El Niño Southern Oscillation (ENSO) event was captured and recorded by NASA Earth observing satellites. By downloading and plotting that satellite data, students will observe and analyze El Niño's effect on sea level height and sea surface temperatures.

## GPM in a Minute Video

In a one minute time lapse video, viewers are shown the assembly sequence of the Global Precipitation Measurement satellite from its 2011 beginning at Goddard Space Flight Center in Maryland to its 2014 launch at Tanegashima Space Center in Japan.
