Learners create a "sound cone" and use it to understand how the Deep Space Network antennas pick up radio communications from space.
Learners will decide on the appropriateness of items to take on a long trip to Mars and take into consideration the effects of zero gravity, limited electrical power, etc.
This is an activity about the Doppler effect. Learners begin by simulating the noise made by a passing siren. After learning that the change in pitch results from movement, they investigate the definition of frequency, calculate change in frequency,... (View More) and learn how this applies to light and the study of astronomy. This lesson requires a Doppler ball, also referred to as a buzzer ball. (View Less)
This is an activity about the relation between day length and temperature. In one team, learners will create and analyze a graph of hours of sunlight versus month of the year for a number of latitudes. In another team, learners will graph... (View More) temperature versus month for the same latitudes. The teams then compare data and draw conclusions from their analyses. (View Less)
This science news story explains the impact of the Hubble Space Telescope over the past two decades. The article describes the telescope, its many servicing missions, the public’s favorite images, the top science findings, and the man for whom the... (View More) telescope is named. Star Witness News is a series of articles, written for students, that are inspired by Hubble Space Telescope press releases. Supplemental education materials include background information, vocabulary, and discussion questions and answers. (View Less)
This is an activity exploring the concept that distance affects how we perceive an object's size, specifically pertaining to the size of the Sun and the Moon as seen from Earth. Learners will complete a hands on activity where two balls of differing... (View More) sizes stand in for the Sun and the Moon. By moving the balls away from each other, students will determine how far the larger ball needs to be in order to make the two seem similar in size. They will also use the balls to demonstrate a solar eclipse. Lastly, learners will complete a worksheet explaining their findings. This is Activity 12 of a larger resource entitled Eye on the Sky.

This is an activity about the rotation of the Earth and Sun, and the Earth's revolution around the Sun. In chalk, learners will draw the Sun-Earth system, complete with Earth's orbit, and then act out the rotation and revolution of a yearly cycle.... (View More) Learners will also complete a worksheet to reinforce visual understanding of this model. This activity requires an outdoor location with ample room and is Activity 6 of a larger resource entitled Eye on the Sky. (View Less)
This is an activity about observing and mapping sunspots by direct solar observation. Learners will use a small telescope, binoculars, or a Sunspotter to create a projected image of the Sun and trace the position of any observed sunspots on a piece... (View More) of paper. Additionally, learners will mark the direction of the Sun image’s motion. This is Activity 2 of the Space Weather Forecast curriculum. (View Less)
This is an activity about measurement. Learners will label key points and features on a rectangular equal-area map and measure the distance between pairs of points in order to calculate the actual physical distance on the Sun that the point pairs... (View More) represent. This is Activity 5 of the Space Weather Forecast curriculum. (View Less)
In this introductory activity, learners investigate and discuss infrared images of various everyday objects, such as toasters, hairdryers, and running water, to learn about infrared imaging. Student questions about the false-color images help guide... (View More) a discussion about what they are, how they are different from visible light images, and the information that such images contain. Observation, comparing and contrasting, and reasoning skills are emphasized. The accompanying website features background information for the teacher, pre-requisite skills and knowledge for the student, multiple image sets, assessment information, student worksheets, extension and transfer activities, and additional resources. This is an introductory activity for both the Infrared Zoo and Infrared Yellowstone lessons available on the Cool Cosmos website. (View Less)
