In this activity, students work in teams to calculate relative air mass and demonstrate how solar elevation angle affects the intensity of light that reaches an observer on the ground. The resource includes a student data sheet. It is part of the... (View More) Atmosphere chapter of the GLOBE Teacher's Guide, and is supported by the GLOBE Aerosol protocol. GLOBE (Global Learning and Observation to Benefit the Environment) is a worldwide, hands-on, K-12 school-based science education program. (View Less)

Students will work in teams to create visual models to assist in understanding the volume of surface ozone in the air. Students construct cubes of different volumes and compare them to get a feel for parts per million by volume and parts per billion... (View More) by volume. Resource includes a paper template for creating the cube and a student worksheet. This is a learning activity associated with the GLOBE Atmosphere investigations and is supported by the Atmosphere chapter of the GLOBE Teacher’s Guide. (View Less)

In this activity, students learn the basics of the horizon, direction and the rising and settings of the Sun and stars by making a schoolyard "medicine wheel" with sidewalk chalk on playground asphalt. Medicine wheels are stone rings constructed by... (View More) the Plains people of North America which may have been used as a calendar system based on observations of objects in the sky. This activity requires a flat area at least 6 meters across – preferably asphalt or concrete – that has a good view of the sky. It can be done as a whole class activity. Part 1 of this activity involves constructing the medicine wheel (about 10-15 minutes). Part 2 of this activity involves making ongoing observations throughout the year at noon (about 10-15 minutes for each observation). Part 3 involves making observations from the wheel during after-school hours to observe the rising or setting points of stars, the Sun and Moon. Discussion questions, background information and a math extension activity are included. This activity is the second lesson in the Ancient Eyes Look to the Skies curriculum guide. (View Less)

This is a booklet containing 24 problem sets that involve a variety of math skills, including scientific notation, simple algebra, and calculus. Each set of problems is contained on one page.

(View More) explore space science topics related to our Sun, auroras, solar features, space weather, sunspots, and solar storms. This booklet can be found on the Space Math@NASA website. (View Less)

This is an article about detecting gravitational waves. Learners can read about how the Laser Interferometer Space Antenna (LISA) is detecting gravitational waves. An activity is included about how to build a mini-LISA and use it to explore the... (View More) technology behind the instrument. (View Less)

This is a detailed lesson about heat transfer and distance. Learners will design and conduct experiments to answer the question, "how does distance and inclination affect the amount of heat received from a heat source?" They will measure heat change... (View More) as a function of distance or viewing angle. From that experiment, they will identify how the MESSENGER mission to Mercury takes advantage of these passive cooling methods to keep the spacecraft comfortable in a high-temperature environment. This is lesson 3 from MESSENGER Education Module: Staying Cool. Note: the student guide starts on p. 24 of the PDF. (View Less)

In this activity, students build a model of an active galaxy. From this, they will learn about the geometry of the components of an active galaxy and develop an understanding that different viewing angles can lead to dramatically different... (View More) interpretations of a galaxy's appearance. The activity includes background information, glossary, essential questions, extension activities, transfer activities, adaptations for visually-impaired students, and an answer key. Additional materials needed to do this activity include a compass. This is activity one of three in the Active Galaxies education unit. (View Less)

This article is about the isoperimetric theorem. It states the theorem, explains its history and uses examples and exercises to demonstrate it. The resource is from PUMAS - Practical Uses of Math and Science - a collection of brief examples created...
