In this inquiry activity students work in groups to investigate allelopathy via research, using the scientific method to plan and carry out an experiment, and creating a formal written report and oral presentation.

Biology 2e is designed to cover the scope and sequence requirements of a typical two-semester biology course for science majors. The text provides comprehensive coverage of foundational research and core biology concepts through an evolutionary lens. Biology includes rich features that engage students in scientific inquiry, highlight careers in the biological sciences, and offer everyday applications. The book also includes various types of practice and homework questions that help students understand—and apply—key concepts. The 2nd edition has been revised to incorporate clearer, more current, and more dynamic explanations, while maintaining the same organization as the first edition. Art and illustrations have been substantially improved, and the textbook features additional assessments and related resources.

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.

Hydrogen peroxide (often used as a disinfectant) has also been approved for use in pesticides. This science fair project investigates whether hydrogen peroxide has any effects on seed germination or on roots of plant cuttings.

This activity is a classroom investigation where students gather descriptive data on two different plants with a partner, and on other plants during a classroom discussion.They will then interpret their findings, and classify the plants, if applicable, into monocots or dicots.

In this biology investigation, students will make observations of the growth of bean seeds to determine what plants need to live and grow in a healthy way.

This activity uses a cultural story to excite kinesthetic homework, nature journaling and daily adventure in a child's own back yard or kitchen flower pot.

Tissues and cells of root, stem, and leaf anatomy in both dicots and monocots are investigated in this learning activity.

Plant growth regulators, including auxin, gibberellin, cytokinin, abscisic acid, and ethylene, are investigated in this learning activity to demonstrate how these chemicals (hormones) affect plant growth and development.

Plant water relations are presented in this learning activity to help participants understand the components of water potential, explain how water moves through plants, provide examples of plant adaptations to water stress, and have a general understanding of how water potential can be measured.

Leaves use sunlight to make food for the plant. Sunlight contains all of the colors of the rainbow, but are all of those colors used by the leaf? Can you find out if some colors of light are more important than others?
