This textbook chapter describes the processes through which El Niño and La Niña conditions emerge. The resource includes an animation of ocean currents, and links to current news articles, and a suite of pre- and post-unit assessments. A teacher's... (View More) guide supports classroom use. This is the eighth chapter in the unit, Energy Flow, exploring the transfer of energy between the atmosphere, oceans, land, and living things over short and long timescales. The resource is part of Global System Science (GSS), an interdisciplinary course for high school students that emphasizes how scientists from a wide variety of fields work together to understand significant problems of global impact.

This is a lesson about geologic history. Learners will work together to create models of volcanic lava flows and analyze the layers that form on a planet's surface. They will sequence lava flows produced by multiple eruptions. Students will be asked... (View More) to observe where the flows travel, make a model, and interpret the stratigraphy. Students will use their volcanic layering model to demonstrate the relative dating and geologic mapping principles to later be applied to satellite imagery. The lesson models scientific inquiry using the 5E instructional model and includes teacher notes and vocabulary. (View Less)
This is an activity about albedo, which is a measurement of the reflectance of a planetary surface. Learners will classify areas on an image in terms of albedo values and then sketch their own portion of an image from space. These sketches are... (View More) assembled to view the larger image that the class or group has created. Note: See Related & Supplemental Resources (right side of this page) for a link to download the student pages of this activity. (View Less)
Learners will investigate how lateral velocity affects the orbit of a spacecraft such as the International Space Station (ISS). Mathematical extensions are provided. This is science activity 1 of 2 found in the ISS L.A.B.S. Educator Resource Guide.
Leaners will grow a sugar crystal and learn how this relates to growing protein crystals in space. The lack of gravity allows scientists on the space station to grow big, almost perfect crystals, which are used to help design new medicines. This is...

Learners will investigate how to build a space suit that keeps astronauts cool. This is technology activity 1 of 2 found in the ISS L.A.B.S. Educator Resource Guide.
Learners will investigate the relationship between mass, speed, velocity, and kinetic energy in order to select the best material to be used on a space suit. They will apply an engineering design test procedure to determine impact strength of... (View More) various materials. This is engineering activity 2 of 2 found in the ISS L.A.B.S. Educator Resource Guide. (View Less)
This is an activity about using solar arrays to provide power to the space station. Learners will solve a scenario-based problem by calculating surface areas and determining the amount of power or electricity the solar arrays can create. This is...

In this activity, students are introduced to light and colored gels (filters). Students make and test predictions about light and color using gels; learn about the importance of gels (filters) to astronomers; then analyze images taken with regular... (View More) and infrared cameras to see that objects opaque to light at one wavelength, may be transparent to light of a different wavelength. Section 1 of the activity guide includes teacher notes, information on materials and preparation, student misconceptions, and a student pre-test. Each activity section also includes teacher notes, student activity sheets, and answer keys. This activity is the first of four activities in Active Astronomy, which are designed to complement instruction on the electromagnetic spectrum, focusing on infrared light. (View Less)
In this activity, students build a photocell detector, and use it to detect different colors of light in a spectrum. Then they place the detector just outside the red region of the visible light spectrum and see that the detector detects the... (View More) presence of light there, even though there is no color visible. Students learn that invisible light exists and that we can detect this light with instruments other than our eyes. In a final part of the activity, students investigate the infrared signals emitted by TV and VCR remote controls. The activities build upon each other and are best taught in order. Section 1 of the activity guide includes teacher notes, information on materials and preparation, student misconceptions and a student pre-test. Each activity section also includes teacher notes, student activity sheets, and answer keys. This activity requires some special materials (e.g. a small solar cell, alligator clip leads, plus common classroom materials (e.g., overhead or slide projector). This activity is the second of four activities in Active Astronomy, which are designed to complement instruction on the electromagnetic spectrum, focusing on infrared light. (View Less)
