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) activity, students write a story about their ice core. (View Less)

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) one hand as many balls (photons) as possible. Drops occur on carpeted and non-carpeted areas, and with and without the presence of cardboard buildings, to represent different Earth surfaces. The lesson includes background information, instructions and concluding questions. Related Next Generation Science Standards (NGSS) are listed. (View Less)

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) part of Earth Math: A Brief Mathematical Guide to Earth Science and Climate Change. (View Less)

In this field activity, students observe clouds, and are introduced to dichotomous key to classify cloud types. Students also make weather observations of current weather and record and track changes in weather over time. Materials/equipment needed... (View More) include weather instruments (thermometers and barometers) and graph paper. A student self-assessment rubric, vocabulary linked to an on-line glossary, a list of elementary level trade books on weather, and teacher notes and class management suggestions are provided. This hands-on activity is related to NASA CERES Students' Cloud Observations Online (S’COOL) project. (View Less)

In this problem set, learners will practice fractions by working with the ratios of various molecules or atoms in different compounds to answer a series of questions. Answer key is provided. This is part of Earth Math: A Brief Mathematical Guide to... (View More) Earth Science and Climate Change. (View Less)

In this problem set, learners will answer a series of questions about the complex molecule, Propanal. Answer key is provided. This is part of Earth Math: A Brief Mathematical Guide to Earth Science and Climate Change.

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) answer key are provided.

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) these objects with a magnifying lens. Students will use various objects in the classroom to experiment with nonstandard measurement. They will make estimates and test them out. Then, working in pairs or small groups, students will use a ruler or a measuring tape to become familiar with how to use these tools for standard linear measurement. Uses commonly available or inexpensive materials (magnifying glass, construction paper, scissors,salt and sugar, crayons or chalk). This is the 2nd of 3 sets of learning activities that are companion activities to the Elementary GLOBE children's book, Discoveries at Willow Creek. Includes a teacher implementation guide. GLOBE (Global Learning and Observation to Benefit the Environment) is a worldwide, hands-on, K-12 school-based science education program. (View Less)
