# Angular Measure

Students will learn about the Transit of Venus through reading a NASA press release and viewing a NASA eClips video that describes several ways to observe transits. Then students will study angular measurement by learning about parallax and how... (View More)

Audience: Middle school
Materials Cost: Free

# Designing an Open Spectrograph

Learners will build an open spectrograph to calculate the angle the light is transmitted through a holographic diffraction grating. After finding the desired angles, the students will design their own spectrograph using the information learned. The... (View More)

# Estimating Planar Areas Using Analogue Methods

This math problem determines the areas of simple and complex planar figures using measurement of mass and proportional constructs. Materials are inexpensive or easily found (poster board, scissors, ruler, sharp pencil, right angle), but also... (View More)

# Classroom Solar Calendar

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)

# Calculating Relative Air Mass

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)

# Learning to Use Visualizations

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. This learning... (View More)

# Building Perspectives with Active Galaxies

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)

# Zooming In on Active Galaxies

This activity focuses on the question, What do active galaxies look like when viewed from different distances? Students work in small groups to learn about the small angle formula, construct a template, and use it to correctly measure the angular... (View More)

Audience: High school
Materials Cost: \$1 - \$5 per group of students

# Technology Teacher: Mapping the Watery Hills and Dales

This article discusses how Global Positioning System (GPS) satellites work, and how the TOPEX and Jason-1 satellites use GPS data in making very precise topological maps of the oceans. The article includes an activity. Students are divided into two... (View More)
