Dangers of Radiation Exposure

This is a lesson about radiation and the various sources of radiation that a spacecraft may encounter in its journey.

Water Walk

In this field activity, students conduct a visual survey of a hydrology study site, and collect information about land cover and water quality. These observations are used to stimulate research-able questions about land cover and water chemistry that can be the focus of future investigations.

Searching for Life on Mars

This is a lesson about the search for life on Mars. Learners will participate in three activities. In the first activity (Imaginary Martians) learners will compare a fictional organism with what they know about life on Mars today.

GLAST Launch Fact Sheet

This four-page color brochure describes the science of NASA's GLAST mission, as well as providing tables that summarize the instrumental parameters and the mission participants.

The Sun as a Star

This is an activity about perspective. Learners will examine pictures of objects up close and far away to try and figure out what they are.

Make a UV Detector

On a bright, sunny day, learners will use tonic water to detect ultraviolet (UV) light from the Sun. This activity is from the DIY Sun Science app and is for ages 7 and up

NuSTAR Paper Model

This is a paper model of the Nuclear Spectroscopic Telescope Array (NuSTAR) satellite.

What Else Do We Want to Find Out About Mars?

This is an activity about modeling and the scientific process. Learners will discuss the models they created in the previous three activities as models of forces that shape the surface of planets, and talk about the similarities and differences between models and real events.

NASA eClips™️ Real World: Scaling the Solar System

Focusing on the size of our solar system, these two short videos address both its vastness and the measurement of its distances. Part One defines the limits of the solar system; Part Two introduces the Astronomical Unit (AU) and applies it to distances within the solar system.

Me and My Shadow

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.
