In this activity, students are introduced to light and colored gels (filters). Students make and test predictions about light and color using gels; learn about the importance of gels (filters) to astronomers; then analyze images taken with regular... (View More)

In this activity, students build a photocell detector, and use it to detect different colors of light in a spectrum. Then they place the detector just outside the red region of the visible light spectrum and see that the detector detects the... (View More)

This activity introduces the electromagnetic spectrum. A riddle is proposed and users stroll through an imaginary amusement park to identify the object being described. During the journey, they discover the different types of electromagnetic energy... (View More)

Audience: Informal education

This is a lesson about using light to identify the composition of an object. Learners will use a spectrograph to gather data about light sources. Using the data they’ve collected, students are able to make comparisons between different light... (View More)

This is an activity about constellations. Learners will make a "star finder" toy and play a game to find a constellation in the night sky.

This is a lesson about detecting atmospheres of planets. Learners will explore stellar occultation events (by interpreting light curves) to determine if an imaginary dwarf planet “Snorkzat” has an atmosphere. The activity is part of Project... (View More)

In this activity, children make a mobile of galaxies; patterns and instructions are included. It introduces the different shapes of galaxies and their nomenclature. Note that young children will need assistance from an adult or older child to safely... (View More)

This is an activity about detecting elements by using light. Learners will develop and apply methods to identify and interpret patterns to the identification of fingerprints. They look at fingerprints of their classmates, snowflakes, and finally... (View More)

This is a math-science integrated unit about spectrographs. Learners will find and calculate the angle that light is transmitted through a holographic diffraction grating using trigonometry. After finding this angle, the students will build their... (View More)

Audience: High school

This Hubble Space Telescope image shows an especially photogenic group of interacting galaxies called Arp 273. The larger of the spiral galaxies, also known as UGC 1810, has a disk that is distorted into a rose-like shape by the gravitational tidal... (View More)
