Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.

Instructions for building and utilizing an origami tetrahedron in order to better understand the rotational symmetry group of a tetrahedron in abstract algebra.

Students learn how to use wind energy to combat gravity and create lift by creating their own tetrahedral kites capable of flying. They explore different tetrahedron kite designs, learning that the geometry of the tetrahedron shape lends itself well to kites and wings because of its advantageous strength-to-weight ratio. Then they design their own kites using drinking straws, string, lightweight paper/plastic and glue/tape. Student teams experience the full engineering design cycle as if they are aeronautical engineers—they determine the project constraints, research the problem, brainstorm ideas, select a promising design and build a prototype; then they test and redesign to achieve a successful flying kite. Pre/post quizzes and a worksheet are provided.

This unit provides the framework for conducting an “engineering design field day” that combines 6 hands-on engineering activities into a culminating school (or multi-school) competition. The activities are a mix of design and problem-solving projects inspired by real-world engineering challenges: kite making, sail cars, tall towers, strong towers and a ball and tools obstacle course. The assortment of events engage children who have varied interests and cover a range of disciplines such as aerospace, mechanical and civil engineering. An optional math test—for each of grades 1-6—is provided as an alternative activity to incorporate into the field day event. Of course, the 6 activities in this unit also are suitable to conduct as standalone activities that are unaffiliated with a big event.
