Through the use of the 5E instructional model, students discover the value of using color maps to visualize data. The activity requires students to create a color map of the ozone hole from Dobson data values derived from the Aura satellite. Students then interpret that map and compare and evaluate different color scales.

Students build their understanding of the terms "compare" and "contrast" by participating in class discussions, using Internet resources, working collaboratively, and by visually representing information in a Venn diagram.

Students add up the effect of images and persuasive language to analyze the art and words in advertisements.

Students make sense of dollars and cents when they study the importance of saving and budgeting in this lesson.

Interaction and adventure draws high school and elementary school students together as they analyze stories about the Lewis and Clark expedition.

History takes on new dimensions in this interactive multimedia lesson that emphasizes the B-D-A approach to research as students investigate the experiences of people with disabilities since the early 1800s.

Students will use a Scanning Electron Microscope to observe and classify lichen. Students will design a field-based investigation to determine the relationship between an abiotic factor and lichen.

This is an activity about ellipses, their focal points, and how the mathematics involved pertains to planetary orbits. Learners will draw their own ellipse using a string and pencil and calculate the minimum and maximum distance from the Sun for each of the planets. This activity requires access to the Space Weather software and is Solar System Activity 5 in a larger resource, titled Space Update.

Students learn about energy, kinetic energy, potential energy, and energy transfer through a series of three lessons and three activities. They learn that energy can be neither created nor destroyed and that relationships exist between a moving object's mass and velocity. The associated activities give students hands-on experience with examples of potential-to-kinetic energy transfers. The activities also provide ways for students to apply the core concepts of energy through engineering practices such as building and testing prototypes to meet design criteria, planning and carrying out investigations, collecting and interpreting data, optimizing a system design, and collaborating with other research groups. The fundamental concepts presented in this unit serve as a good foundation for future lessons on energy technologies and electricity production.

Exploring Environmental Issues: Biodiversity was developed by Project Learning Tree in partnership with the World Wildlife Fund. In this sixty-page module, students learn that decisions about growth and development, energy use and water quality, and even human health, all rest to some extent on perspectives about biodiversity. Educators and students step back from biodiversity issues and specific species to examine broader concepts and larger connections—not just biological, but political, cultural, ethical, and economic as well. Educators can download the complete Exploring Environmental Issues: Biodiversity module at no cost.

The word “biotechnology” usually conjures images of modern techniques and topics of controversy such as cloning, stem cell research, and genetically modified organisms. However, the practice of manipulating organisms to create a product has long been used by human societies. Our Biotechnology Series is designed for high school and community college educators in the fields of Biology, Environmental Science, Social Studies, and Agriculture. A special effort has been made to construct activities that support instruction in AP Biology, AP Environmental Science, and AP Human Geography. This module was created as a supplement to the Focus on Risk curriculum. Educators can download the complete Exploring Environmental Issues: Biotechnology module at no cost.

Students read AviŐs "Nothing But the Truth" and examine the First Amendment and student rights, and then decide whether the rights of the novel's protagonist, Philip, are violated.

Students make predictions about "Bridge to Terabithia" and its characters, complete character studies, and relate the characters' experiences to their own as they identify ways to make and keep friends.

Student teams explore atmospheric aerosols, dust, and fires and their impact on the Earth's albedo using NASA Earth Observations (NEO) website. This is an extension activity in the student learning activity guide accompanying the GLOBE Earth System Poster, Exploring Connections in Year 2007. A series of six learning activities and associated assessment activities are included.

This virtual field trip embedded within a Nearpod VR lesson uses real-world examples of geometry to help students analyze and design physical spaces.

As with all of the Nearpod VR lessons, this virtual field trip includes a teacher guide and student resources.

Students explore the sound, evolution, performance techniques, and culture of guitar-like instruments from around the world.

Nonfiction may be dull for some students, but this lesson helps them focus on the main ideas. Through awareness of section headings, students learn to sort and categorize main concepts.

After reading "All Quiet on the Western Front", students discuss the novel's ironic ending, then compose alternate titles and endings for the book, and design new book covers.
