Students are introduced to air masses, with an emphasis on the differences between and characteristics of high- versus low-pressure air systems. Students also hear about weather forecasting instrumentation and how engineers work to improve these instruments for atmospheric measurements on Earth and in space.

Students learn what causes air pollution and how to investigate the different pollutants that exist, such as toxic gases and particulate matter. They investigate the technologies developed by engineers to reduce air pollution.

During World War Two, a fierce battle between American and Japanese forces on Kwajalein atoll left a trail of debris on the deep lagoon floor. This lagoon now has one of the largest collections of well-preserved aircraft in the world. In this video, as part of the first ever film crew allowed onto this secret military base, Jonathan explores a B-25, F4-U Corsair and Dauntless dive bomber still sitting on the bottom of the ocean, as if ready to take off. Please see the accompanying study guide for educational objectives and discussion points.

How much of an impact does air travel have on climate change? What can be done about it? Through a hands-on demonstration and a short literature review, students consider the impacts and future of aviation. With data, students consider why climate communicators and scientists focus on carbon dioxide. This guide is an extension of the TILclimate episode "TIL about planes."

This lesson looks at the natural resources that drew businesses to Alabama. Students will explore the adapted 1820 letter from Mason and Dexter in Cahaba, Alabama to Richards and Simmons in Cumberland, Rhode Island. Students will explain ideas within this historical text based on specific information presented in this primary source. This lesson can be used as a stand alone or can follow A Natural Attraction: The Natural Resources of Alabama During the Early Nineteenth Century . This lesson was created in partnership with the Alabama Department of Archives and History.

In this lesson, students will work in small groups to examine a letter describing the environment of Alabama and identify reasons which might have encouraged settlers to move to Alabama in the early nineteenth century. Students will choose an interesting attraction of Alabama mentioned in the letter and design a postage stamp around that attraction. This lesson was created in partnership with the Alabama Department of Archives and History.

In this lesson, students will learn about the executive branch of government at the state level, especially related to the first governors of the state of Alabama. Their impact on the development of Alabama and Alabama's role in the United States will be discussed. Students will use research and note taking skills to gather information on an early governor. Then students will participate in jigsaw groups to share their information, discuss the importance of each governor, similarities, and impact. Finally, students will discuss the role of governor and how governors have an impact on the state and the impact these men had in Alabama and in other states. This lesson was created in partnership with the Alabama Department of Archives and History.

Students will read a description of the pine barrens by Basil Hall and analyze the text by using the 3-2-1 strategy. Students will discuss the life and work of Basil Hall, including his travels and journaling in North America. They will observe how a camera lucida functions and debate whether using a camera lucida is "cheating" in art. Next, students will venture outside to create a sketch of their environment while appropriately utilizing materials. They will compare and contrast their products to the sketches of Basil Hall and critique each other's work. This lesson was created in partnership with the Alabama Department of Archives and History.

Tradition and technology come together in this lesson in which students learn about Alaskan animals through Native American tales and their own online research.

In the story, Alexander, Who Used to Be Rich Last Sunday, Alexander receives a dollar from his grandparents that he plans to save, but he spends it all, a little at a time. In this lesson, students count by twos to fill a container with 100 pennies. They are asked whether 100 pennies is the same amount of money as one dollar. They listen to the story and as Alexander spends his money, students come up and remove the correct number of pennies from a container. At the end of the story, students are again asked if 100 pennies is the same amount of money as one dollar. Students discuss the choices that Alexander made and give advice on how he could save his money to reach his goal of buying a walkie-talkie.

CK-12 Algebra Explorations is a hands-on series of activities that guides students from Pre-K to Grade 7 through algebraic concepts.

National Board Certified teacher Marlo Warburton introduces a fresh approach to teaching the notoriously difficult "mixture" word problems for Algebra I. Using an in-class demonstration and incorporating basic physics principles of weight and distance, Ms. Warburton helps her students visualize, solve -- and even enjoy! -- these challenging problems.

This lesson is about trying to get students to make connections between ideas about equations, inequalities, and expressions. The lesson is designed to give students opportunities to use mathematical vocabulary for a purpose to describe, discuss, and work with these symbol strings.The idea is for students to start gathering global information by looking at the whole number string rather than thinking only about individual procedures or steps. Hopefully students will begin to see the symbol strings as mathematical objects with their own unique set of attributes. (7th Grade Math)

Studied students stupefy! Students learn about alliteration by listening to an alliterative read-aloud and apply the knowledge they gain to the creation of their own poem and illustration.

Students explore their towns' landmarks, symbols, and people; look at brochures and other informational tools; practice writing for a specific audience and revising; and work collaboratively to create a brochure.

Students learn about the differences between types of water (surface and ground), as well as the differences between streams, rivers and lakes. Then, they learn about dissolved organic matter (DOM), and the role it plays in identifying drinking water sources. Finally, students are introduced to conventional drinking water treatment processes.

Students will observe dance movements depicted in a drawing and a painting. Partners will use simple lines to draw their partner's movements and paint dance costumes on the figures using various brushstrokes. Students will write a persuasive speech to the school superintendent explaining why they believe dance should be a regular part of the curriculum. They will then model dance movements for classmates in teams of four and recite their persuasive speech to the class.

In this inquiry activity students work in groups to investigate allelopathy via research, using the scientific method to plan and carry out an experiment, and creating a formal written report and oral presentation.

Students learn about alliteration, and then practice using alliteration in acrostic poems, tongue twisters, alphabet books, and number books.
