After reading the accompanying background information, students create an ice core using a tennis ball container and an assortment of dyes and craft supplies. Students measure the thickness and determine the age of each layer. As an extension... (View More)

This multi-phased learning package progresses from guided engineering to an open mission-design challenge. Each step is scaffolded and includes easy-to-implement teaching tools, lessons and art activities. Learners, working in collaborative teams,... (View More)

Acting as the ICESat-2 satellite, students investigate the reflection of light photons off Earth's surface by catching and recording a number of photons. Using bouncy balls to represent the photons, students drop, let bounce once and try to catch in... (View More)

This problem set is about scale. Using a ruler, learners will measure the distance between two points on a satellite image and determine the scale of the image and other information to answer a series of questions. Answer key is provided. This is... (View More)

In this problem set, learners will analyze an image of Washington, DC, taken from orbit. They will determine scale and take measurements of several features in the image. A link to more images taken from the International Space Station and the... (View More)

Students will learn about magnification and how a magnifying lens works. They will examine a variety of different objects, first without a magnifier and then with a magnifier, and compare what they observe. They will practice observing details of... (View More)

In this activity, students engage in an ongoing investigation to find patterns of sunlight and shadow in a classroom (or any room that gets sunlight) at different times of the day and different times of the year. Students look for repeating... (View More)

This activity explores how ancient Sun observers made use of natural and built structures to mark solar alignments observed at different times of the year, particularly around the solstices and equinoxes. In Part 1, the teacher prepares a horizon... (View More)

This is a lesson about designing and building an effective sunshade for a model MESSENGER craft. Learners will build a model of MESSENGER. They will use a scientific approach to solve problems and work as a cooperative team. They will discover their... (View More)

This is an activity about sampling in astronomy. Learners will make a sampling window in order to estimate the number of stars in the sky visible to the unaided eye. After, they will discuss how to estimate the effect of different variables on their... (View More)
