This learning video introduces high school students to a topic they would not ordinarily study in school, biotechnology, and to different applications of biotechnology that relate to the main theme of the module - making the desert greener. After reviewing traditional methods used for manipulating plants to produce desired traits, students will learn about the methods of making transgenic plants. Dr. Ziad discusses a real world problem that is critical in his country, Jordan, where much of the land is desert. A prerequisite to this video lesson is some background in biology.
Students will compare different plant traits and determine how each structure helps that species of plant grow and reproduce in the schoolyard habitat. After which, students can observe each plant for acquired traits.
"Botany in Hawai‘i" discusses introductory topics of Botany through examples of the native and introduced plants found in Hawai‘i. It includes anatomy and physiology of seeds, roots, leaves, stems, fruits and flowers and covers the main plant groups from nonvascular to flowering plants. This book provides a visual reference to botanical concepts and terminology for beginners.
Submitted as part of the California Learning Resource Network (CLRN) Phase 3 Digital Textbook Initiative (CA DTI3), CK-12 Foundation’s high school Biology FlexBook covers cell biology, genetics, evolution, ecology, botany, zoology, and physiology. This digital textbook was reviewed for its alignment with California content standards.
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.

In this activity, students use a spreadsheet to calculate the net carbon sequestration in a set of trees; they will utilize an allometric approach based upon parameters measured on the individual trees. They determine the species of trees in the set, measure trunk diameter at a particular height, and use the spreadsheet to calculate carbon content of the tree using forestry research data.
In this video segment from NatureScene, explore Cartwheel Bay, a wetland in South Carolina, and learn about the variety of carnivorous plants native to this unique landform.
In this video adapted from Texas Parks and Wildlife Department, learn about carnivorous plants that act as both producers and consumers in an ecosystem. See sundews and blatterworts capture and digest insects.
This video will help students, particularly those not in AP-level classes, have a practical application for knowing about the major divisions between plants, particularly about the details of plant anatomy and reproduction. Students will be able to :Identify the major evolutionary innovations that separate plant divisions, and classify plants as belonging to one of those divisions based on phenotypic differences in plants. Classify plants by their pollen dispersal methods using pollen dispersal mapping, and justify the location of a _crime scene_ using map analysis. Analyze and present their analysis of banding patterns from DNA fingerprinting done using plants in a forensic context.
This sequence of instruction was developed in the Growing Elementary Science Project to help elementary teachers who were working remotely. We developed a short storyline that ties together a few sessions to help explore a specific concept. We tried to include some activities that honored and included the student’s family and experience, and some that included the potential for ELA learning goals. Students view a couple of videos and record what they notice and wonder about how plants change as seasons change. Students take a walk with family members to search for evidence of changes due to weather in their neighborhoods. It is part of ClimeTime - a collaboration among all nine Educational Service Districts (ESDs) in Washington and many Community Partners to provide programs for science teacher training around Next Generation Science Standards (NGSS) and climate science, thanks to grant money made available to the Office of the Superintendent of Public Instruction (OSPI) by Governor Inslee.
After learning about and observing the differences between flowering and nonflowering plants, students go outside and search for plants in schoolyard, keeping notes and drawings of their observations.
Students investigate decomposers and the role of decomposers in maintaining the flow of nutrients in an environment. Students also learn how engineers use decomposers to help clean up wastes in a process known as bioremediation. This lesson concludes a series of six lessons in which students use their growing understanding of various environments and the engineering design process, to design and create their own model biodome ecosystems.
