NASA Wavelength

Earth's Orbit

In this activity, learners draw a circle with a single focus, an ellipse with two foci close together, and an ellipse with two foci far apart, and compare the shapes.

Lunar Reconnaissance Orbiter Communication Design Challenge

In this activity, teams of learners will model how scientists and engineers design and build spacecraft to collect, store, and transmit data to Earth.

Experimenting with UV-Sensitive Beads

Participants experiment with ultraviolet light sensitive plastic beads, which are generally white but turn colors when exposed to UV light.

Building Intuition for In-water Optics and Ocean Color Remote Sensing: Spectrophotometer Activity with littleBits™

This activity demonstrates optical properties of water: that different constituents in water affect the transmission, absorption, and scattering of different colors in the visible light spectrum.

Exploring Solar Systems Across the Universe

Learners will investigate, compare, and describe patterns in Solar System data. They will then hypothesize about the formation of the Solar System based on data and explain how extrasolar planets can be discovered.

ClimateBits: El Niño

This brief (1:58) video provides an explanation of El Niño and its impact on the marine food web. Satellite images of a large El Niño in 2015 show the impact on both water temperature and phytoplankton blooms.

Sundial: When is High Noon, and How High is It?

This is a lesson plan for an activity about the nature of the Sun's apparent motion throughout the day. Learners will follow detailed instructions to construct a sundial using everyday materials and make measurements of the shadow cast by the sundial.


In this assessment activity, students generate a data sample from either the Hubble Deep Field-North or Hubble Deep Field-South images, and compare the sample to data from the unselected field. This provides students with a real-life example of how statistics can be used by scientists.

Climate Kids: What Else Do We Need To Find Out?

NASA scientists, using several NASA Earth observing satellites, continue to seek answers to questions related to climate change.

Water Vapor Imagery: Water Vapor and Jet Streams

This is a self-paced, on-line tutorial where learners can identify and analyze jet streams using water vapor imagery from weather satellites. Learners are introduced to the concept and function of the water vapor channel and how these images compare with weather models.
