In this lesson, students will investigate objects' appearance in varying levels of light to help them construct an explanation that objects can only be seen when light is available to illuminate them. Students will discuss why objects look different in a dark room and graph their preferences for sleeping with a light on or off. Then, they will investigate how an object's appearance changes in different lighting conditions in small group centers. Finally, they will model the moon's path around the sun to see how light from the sun causes the moon's appearance to change as it orbits Earth. At the conclusion of the lesson, students will use their experiences as evidence to explain that light is essential for sight. This lesson results from the ALEX Resource Gap Project.

In this lesson, students are asked to provide a written description of both an exponential function and its inverse. They are then introduced to the logarithmic function and will practice writing exponential functions as logarithms and logarithms as exponential functions. Students will evaluate logarithmic expressions and will solve logarithmic equations. This lesson results from the ALEX Gap Resource Project.

Students will read from an Alabama newspaper about President James Monroe's surprise visit to Huntsville.

This lesson is designed to teach students to measure angles with a protractor. The student will be taught how to read the protractor correctly by using either the top or bottom set of numbers. The lesson will reinforce classifying angles as acute, right, and obtuse. The student will sketch angles given a specified measure. This lesson results from the ALEX Resource Gap Project.

Students will develop an understanding of volume and density by analyzing, calculating, and measuring a gummy bear. The students will determine the cause and effect of a water-soaked gummy bear. Students will measure water and gummy bear with accuracy, record data, and communicate their results. This lesson results from collaboration between the Alabama State Department of Education and ASTA.

In this lesson, students will research one Native American group from each of the six main biomes in North America. Students will use their developing technology and language arts skills to find reliable sources on the internet, evaluate and integrate information from these texts, select a suitable digital platform to share their findings, and create a cohesive presentation showcasing their mastery of the learning outcomes. Students will discover the climate, landforms, water, and other natural resources available within each region and how they were used by the natives living there. Students will explore the relationships between the cultures found within each region and its resources. This unit was created as part of the ALEX Interdisciplinary Resource Development Summit.

This lesson looks at the natural resources that drew settlers to Alabama. Students will explore the 1818 letter from Joseph Noble to his friend, Samuel B. Bidgood, describing the town at Tuscaloosa Falls. Students will explain ideas within this historical text based on specific information presented in this primary source. Follow up lesson - Alabama: A Boundless Field of Speculation This lesson was created in partnership with the Alabama Department of Archives and History.

Each student becomes an expert on a natural disaster, investigating and discovering how they can prepare for it. Students initially create traditional motivational posters using paper, pencils, markers, and crayons. Then, students create an electronic version to motivate others to prepare for natural disasters. Next, students create storyboards/scripts and digital stories on a natural disaster of their choosing to inform others of ways to prepare for natural disasters. This lesson was created as part of a collaboration between Alabama Technology in Motion and ALEX.

The lesson content is connected to Alabama Course of Study SS2010 (4) which will explain why significant leaders of the Creek War disrupted the Alabama Creek Indian Headsmen and the government. The disruption would be solved through negotiation. The negotiating Creek Indians did not obtain full restoration of their land, however, they did accept a compromise. This lesson was created in partnership with the Alabama Department of Archives and History.

In this lesson, students will be examining primary sources pertaining to differing viewpoints of America's involvement in World War I. The students will annotate the documents, looking for main ideas and supporting details. The students will then form graphic organizers separating two opposing viewpoints. Finally, students will write a group expository essay using the data from the graphic organizer. This lesson was created as part of the Alabama Bicentennial Commission's Curriculum Development Project.

The lesson will begin by students performing a think-aloud as they consider the similarities of five words: tornado, shelter, basement, underground, and safe room. Students will use a pros and cons graphic organizer as they read articles on three different types of tornado shelters: underground shelters, part of the house shelters, and prebuilt shelters. The students will find the advantages and disadvantages of each type of structure. At the end of the lesson, the teacher will create a table that lists all the shelters and the pros and cons of each. Students will then determine which shelter they feel is most efficient in an "exit slip" response. This unit was created as part of the ALEX Interdisciplinary Resource Development Summit.

Pictures of Alabama State Capitols are provided in this lesson to give students the opportunity to research information that could help them to give their point of view. It will be up to the students to provide further information about the pictures. This will start a conversation about the best location for a capital city and its capitol building.
