Through the use of prisms and glue sticks, this activity introduces students to a fundamental property of light: white light is made up of colors representing different wavelengths. Students use the results of the activity to explain the variation... (View More)

Become a crime scene investigator! Learners model Dawn Mission scientists, engineers, and technologists and how they use instrumentation to detect distant worlds. After a briefing right here on Earth to build context, students explore interactions... (View More)

This activity allows participants to build a paper model of the GPM Core Observatory and learn about the technology the satellite uses to measure precipitation from space. Directions explain how to cut, fold and glue the individual pieces together... (View More)

This lesson was developed to give participants an understanding of Earth's water cycle. In this one-hour long activity, students participate in a webquest to learn about the water cycle, and then build a mini-model of the water cycle to observe how... (View More)

In this inquiry activity, teams of students are challenged with engineering a greenhouse heat trap for use with exotic plants. The investigation requires thermometers, plastic wrap, and a shoebox for each team. Students graph data and determine the... (View More)

In this lesson, students explore a discrepant event when they design an experiment to measure the rate that ice melts when in pure water versus salt water. It is designed to help students realize that a carefully-designed experiment may yield... (View More)

In this activity, students compare two images of the Crab Nebula taken more than 40 years apart. By measuring the motion of some of the knots of glowing gas in the neubla, students will be able to determine the date of the supernova explosion that... (View More)

This article discusses the differences between ozone in the stratosphere and troposphere, and how NASA is measuring ozone using a spectrometer on-board the Aura satellite. The article includes an activity: building a spectroscope using a DVD cover... (View More)
