This is a hands-on project that uses George Orwell's novel, Animal Farm, as the touchstone text. Students work in groups to construct a functioning windmill that can generate electricity. Each student has a role based on the characters in the book. There are also segments of the project that focus on extracting key information from the text.

Students will use linear equations to solve unknown angle problems and other problems presented within context to understand that solving algebraic equations is all about the numbers. They use the number line to understand the properties of inequality and recognize when to preserve the inequality and when to reverse the inequality when solving problems leading to inequalities. They also interpret solutions within the context of problems. Additionally, students extend their study of geometric figures and the relationships between them as they apply their work with expressions and equations to solve problems

This is a set of three, one-page problems about the size and area of solar panels used to generate power. Learners will will use integer arithmetic to tally the number of hydrogen, oxygen and carbon atoms in a molecule and determine the number of methane atoms that can result. Options are presented so that students may learn about how NASA is using signs of methane gas to search for life on other planets, such as Mars, through a NASA press release or about how astrobiologists who are looking for life beyond Earth are using spectroscopy to identify methane plumes on Mars by viewing a NASA eClips video [7 min.]. This activity is part of the Space Math multi-media modules that integrate NASA press releases, NASA archival video, and mathematics problems targeted at specific math standards commonly encountered in middle school.
