In Florida's humid climate, strawberry growers are in a constant battle with two kinds of fruit rot. Using a decision support system, they can save money by spraying fields only when the plant diseases are a threat.

In this Interactive Lecture Demonstration, students will predict the main issues that might be included in short French language videos treating topics such as endangered species, organic farming, the effect of aerosols on the environment, pollution and sustainable development. They will then view short videos on the topics and reflect on how their prior assumptions meshed with reality.

OER Fundamentals are invited to remix this course planning template to design and share their OER project plans, course information and syllabus, and reflection.

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.

The story is about a little boy who tries in vain to save, but unfortunately makes poor decisions and squanders his money.

Does Alexander deserve to be called “The Great?” This inquiry leads students through an investigation of Alexander the Great using a variety of sources to analyze his impact on other cultures, his success as a military general, followed by his lasting impacts on the ancient world.

"Democracy in America" by Alexis de Tocqueville is one of the most influential books ever written about America. While historians have viewed "Democracy" as a rich source about the age of Andrew Jackson, Tocqueville was more of a political thinker than a historian. His "new political science" offers insights into the problematic issues faced by democratic society.

The problem statement describes a changing algae population as reported by the Maryland Department of Natural Resources. In part (a), students are expected to build an exponential function modeling algae concentration from the description given of the relationship between concentrations in cells/ml and days of rapid growth (F-LE.2).

Students are introduced to biofuels, biological engineers, algae and how they grow (photosynthesis), and what parts of algae can be used for biofuel (biomass from oils, starches, cell wall sugars). Through this lesson, plants—and specifically algae—are presented as an energy solution. Students learn that breaking apart algal cell walls enables access to oil, starch, and cell wall sugars for biofuel production. Students compare/contrast biofuels and fossil fuels. They learn about the field of biological engineering, including what biological engineers do. A 20-slide PowerPoint® presentation is provided that supports students taking notes in the Cornell format. Short pre- and post-quizzes are provided. This lesson prepares students to conduct the associated activity in which they make and then eat edible algal cell models.

The Algae-in-a-Bottle Experiment provides an engaging and flexible high-impact teaching tool for helping students to know, understand, and apply a number of concepts related to the biology and ecology of aquatic plants and their environments.
