This lesson is an introduction to Binomial Expansion and the Binomial Theorem. Students begin by expanding binomials using multiplication. They will examine the expansions looking for patterns. These patterns will be used to develop the Binomial Theorem. Both Pascal's Triangle and Combinations will be used to complete the Binomial Expansion. This lesson results from the ALEX Resource Gap Project.

This is a technology-based Biology lesson on the Biomes of the world. Students will work in groups and research their designated terrestrial biome. Students will research abiotic and biotic factors about their biome. Students will create a digital presentation of their biome using Haiku Deck. The presentation will summarize how the abiotic and biotic factors interact in their biome. Students will then use the collected data from the presentations to create food chains and food webs for their designated biomes. This lesson plan results from a collaboration between the Alabama State Department of Education and ASTA.

In this lesson students investigate the effects of black carbon on arctic warming and are introduced to a mechanism of arctic warming that is not directly dependent on greenhouse gases in the atmosphere: black carbon deposition on Arctic snow and ice. It can also be used to introduce the concept of albedo. Prerequisite knowledge: students understand the concepts of absorption and reflection of light energy. This lesson is designed to be used with either an Earth/environmental science or chemistry curriculum. It may also be used as an enrichment activity in physics or physical science during a unit on energy. Includes suggested modifications for students with special needs and low technology option. Requires advance preparation, including freezing ice samples overnight.

This inquiry-based lesson allows students to explore how energy is transferred through a wave. This lesson results from a collaboration between the Alabama State Department of Education and ASTA.

In this lesson, students will examine electronegativities of atoms relative to one another to determine if a covalent bond will be classified as polar or nonpolar. Students will use an online simulation to help them understand the importance of lone pairs of electrons as well as bonding pairs of electrons. Students will use ball-and-stick models to examine and identify the shapes of various molecules. This lesson results from a collaboration between the Alabama State Department of Education and ASTA.

This inquiry examines the 20th century history of migration from Mexico to the United States and recent efforts to limit the movement of people across the southern U.S. border. The inquiry takes its inspiration from a 2018 podcast episode by Malcom Gladwell titled, “General Chapman’s Last Stand.” The podcast is part of Gladwell’s Revisionist History series (http://revisionisthistory.com). In the podcast, Gladwell tells the story of General Leonard F. Chapman Jr., Commandant of the Marine Corps during the Vietnam War, who went on to serve as the Commissioner of the Immigration and Naturalization Service (INS) from 1972 to 1975. Chapman is credited with reforming the INS into a more efficient and effective agency, but Gladwell argues that Chapman’s efforts also led to an unintentional increase in unauthorized immigrants. In 1970, 760,000 Mexican immigrants, or 1.4% of Mexico’s population, lived in the U.S. By 2008, there were 12.7 million Mexican immigrants in the U.S. which amounted to 11% of all people born in Mexico; an increase of almost 800% in less than 30 years. The question of how and why this happened is the central focus of this inquiry.

This activity allows the student to explore problem solving strategies while working with a partner. This activity (building a paper bridge), requires students to question word definition and the application of those definitions. Through problem solving strategies, students discover the need for applying math skills.

This lesson will provide an introduction to finding the inverse of a function or a relation. Through a combination of teacher-led instruction and collaboration, students will discover a method for finding the inverse of a function or relation. The use of an online graphing calculator will aid students with their discovery. This lesson results from the ALEX Resource Gap Project.

This is an integrated lesson which is introduced using the book "The Very Hungry Caterpillar" by Eric Carle. Butterfly metamorphosis is explored through art, math, and writing.

Submitted as part of the California Learning Resource Network (CLRN) Phase 3 Digital Textbook Initiative (CA DTI3), CK-12 Advanced Probability and Statistics introduces students to basic topics in statistics and probability but finishes with the rigorous topics an advanced placement course requires. Includes visualizations of data, introduction to probability, discrete probability distribution, normal distribution, planning and conducting a study, sampling distributions, hypothesis testing, regression and correlation, Chi-Square, analysis of variance, and non-parametric statistics.
