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.

By the end of this section, you will be able to do the following:

Identify the shared characteristics of the natural sciences
Summarize the steps of the scientific method
Compare inductive reasoning with deductive reasoning
Describe the goals of basic science and applied science

This video investigates how to ask questions and test explanations using the scientific method. [11:48]

Khan Academy learning modules include a Community space where users can ask questions and seek help from community members. Educators should consult with their Technology administrators to determine the use of Khan Academy learning modules in their classroom. Please review materials from external sites before sharing with students.

After learning, comparing and contrasting the steps of the engineering design process (EDP) and scientific method, students review the human skeletal system, including the major bones, bone types, bone functions and bone tissues, as well as other details about bone composition. Students then pair-read an article about bones and bone growth and compile their notes to summarize the article. Finally, students complete a homework assignment to review the major bones in the human body, preparing them for the associated activities in which they create and test prototype replacement bones with appropriate densities. Two PowerPoint(TM) presentations, pre-/post-test, handout and worksheet are provided.

In this video, Paul Andersen explains how scientists analyze data and evaluate evidence. He starts with a description of data and how it must be properly displayed. He then describes types of data in each of the four big ideas. He finally discusses a number of practice questions related to data analysis. [6:49]

CK-12’s Life Science delivers a full course of study in the life sciences for the middle school student, relating an understanding of the history, disciplines, tools, and modern techniques of science to the exploration of cell biology, molecular biology, genetics, evolution, prokaryotes, protists,fungi, plants, animals, invertebrates, vertebrates, human biology, and ecology. This digital textbook was reviewed for its alignment with California content standards.

A video showing how the scientific process is not a linear step-by-step process but rather can be illustrated with a flow chart. Follow scientist through this dynamic process as they discover a new species of spider found in a cave. [5:53]

This is a laboratory investigation where students will use the scientific method to solve a new, experimental question in chromatography.

How can you use art to share an experience with someone who was not present at the Vet Bag program? This activity is designed to start your students in recognizing themselves as scientists and thinking critically about problem-solving. The goal is to teach concepts through arts integration and to encourage creativity. As with all lessons provided, please feel free to adapt them according to your students’ abilities. You may find it more successful to lead activities and discussions as a whole group as opposed to having your students work in small groups. Certain scientific vocabulary may or may not be appropriate for your students’ level of understanding. Take these ideas, make them your own and your students will have a greater chance at success.

A video lesson over viewing how to construct a hypothesis explaining the guidelines that need to be followed. Understand that a hypothesis must be logical, account for relevant information, be testable, and be in the simplest form. [2:21]

Using paper towels this activity introduces using the scientific method to set up and test and experiment.

Students gain a basic understanding of the properties of media soil, sand, compost, gravel and how these materials affect the movement of water (infiltration/percolation) into and below the surface of the ground. They learn about permeability, porosity, particle size, surface area, capillary action, storage capacity and field capacity, and how the characteristics of the materials that compose the media layer ultimately affect the recharging of groundwater tables. They test each type of material, determining storage capacity, field capacity and infiltration rates, seeing the effect of media size on infiltration rate and storage. Then teams apply the testing results to the design their own material mixes that best meet the design requirements. To conclude, they talk about how engineers apply what students learned in the activity about the infiltration rates of different soil materials to the design of stormwater management systems.

Green Space Investigation will be the opening activity for an introductory unit in Biology. Purpose of the activity is to model scientific thinking and experience how science is conducted using a confined green space adjacent to a classroom. The activity can be conducted with minimal material needs or can develop into a more elaborate investigation.

Students are presented with a guide to rain garden construction in an activity that culminates the unit and pulls together what they have learned and prepared in materials during the three previous associated activities. They learn about the four vertical zones that make up a typical rain garden with the purpose to cultivate natural infiltration of stormwater. Student groups create personal rain gardens planted with native species that can be installed on the school campus, within the surrounding community, or at students' homes to provide a green infrastructure and low-impact development technology solution for areas with poor drainage that often flood during storm events.

This amazing website provides access to 200 exciting experiments from cartoonist, broadcaster, and engineer, Tim Hunkin. Each experiment is categorized and illustrated.

Introduction to Sociology 2e adheres to the scope and sequence of a typical, one-semester introductory sociology course. It offers comprehensive coverage of core concepts, foundational scholars, and emerging theories, which are supported by a wealth of engaging learning materials. The textbook presents detailed section reviews with rich questions, discussions that help students apply their knowledge, and features that draw learners into the discipline in meaningful ways. The second edition retains the book’s conceptual organization, aligning to most courses, and has been significantly updated to reflect the latest research and provide examples most relevant to today’s students. In order to help instructors transition to the revised version, the 2e changes are described within the preface.
