Material Type: Lesson
Students design, conduct, and analyze a controlled experiment testing the effects of alcohol on the worm C. elegans.
Material Type: Lesson Plan
In this lab activity, students will investigate the movement of different materials across the cell membrane of a raw egg once the egg shell has been dissolved in vinegar. Students will develop an independent investigation in which they will choose a liquid that will re-hydrate the egg that has been dehydrated.
Material Type: Lesson Plan
In this webquest lesson, students will learn about cell division via the Internet. Students will learn about the cell cycle and the stages of mitosis and meiosis. Students will create a portfolio of pictures displaying the steps of mitosis and meiosis.
Material Type: Activity/Lab, Lesson Plan
Students will prepare slides in an attempt to capture cells that are in the process of mitosis. After completing their observations students will calculate the mitotic index.
Material Type: Lesson Plan
In this lesson, students use a mnemonic device for remembering the phases of mitosis.
Material Type: Activity/Lab
This brief video clip discusses the production of specialized cells during human embryonic development.
Material Type: Lesson
In this lesson, students learn how cell specialization takes place in vertebrate embryos. They begin by viewing a gallery of different kinds of specialized cells and exploring how white blood cells are specialized to fight viruses. They will also learn about the role of master control genes in cell development. Finally, they learn about the significance of, and the controversy surrounding, stem cell research, and then analyze different points of view in the stem cell debate.
Material Type: Lesson Plan
This brief video lesson describes DNA and its role and importance in living organisms. This is a very comprehensive overview of how DNA determines form and function, manages protein synthesis within individuals, and ultimately drives evolution. Discussion/assessment questions and suggested supplemental resources are also included.
Material Type: Lecture, Lesson, Lesson Plan, Presentation
This resource outlines Linnaean classification and defines binomial nomenclature. It includes diagrams, practice questions, a study guide, flash cards, interactive assessments, and articles on real world applications.
Material Type: Lesson Plan
This content resource provides the user with a visual representation of enzyme-substrate interactions resulting in a specific product. This is not a complete lesson, but would be beneficial for students as a review prior to an assessment or for teachers as a quick refresher on enzyme-substrate interactions.
Material Type: Diagram/Illustration, Lesson
Students investigate marine food webs and trophic levels, research one marine organism, this activity sand fit their organisms together in a class-created food web showing a balanced marine ecosystem.
Material Type: Activity/Lab, Diagram/Illustration, Interactive, Lesson
This lesson will expose students to some of the problems amoebas have caused to residents of Florida. Studies have shown that virulent strains of amoebas from the genera Naegleria and Acanthamoeba have the ability to grow at high temperatures, while non-virulent strains are unable to grow at normal or elevated body temperatures.
Material Type: Lesson Plan
Students will examine geologic maps in order to assess the likelihood and location of earthquakes in California.
Material Type: Activity/Lab
Students will focus on the structure of the periodic table and the valence electrons in an element. Using this information with the octet rule, students use the power of the table to predict ion formation and the oxidation numbers associated with the ions formed. They will also study the emission of electromagnetic radiation and create models of atoms from clay.
Material Type: Lesson Plan
This diagram shows the relationship between the nuclear binding energy of an isotope and its atomic mass.
Material Type: Diagram/Illustration
In this lesson, students will work in small groups to read and analyze a primary source using a set of questions designed to help them understand the writers' viewpoints. Students will then explain their findings to their classmates. Finally, each student will produce a written essay that explains how and why scientific understanding of the atom has changed over time.
Material Type: Lesson Plan
This resource sheet reviews electrons' energy levels and sublevels within the atom and provides critical thinking questions to assess student understanding of these concepts.
Material Type: Activity/Lab
In this lesson, students will identitfy several forms of acid precipitation. They will list effects of acid precipitaiton and explain the actions that cause the damage. Students will define "buffering" and explain how environmental factors can act as buffers.
Material Type: Lesson Plan
Explore water pollution and its impact on ocean life in aquatic dead zones. GeoInquiries are designed to be fast and easy-to-use instructional resources that incorporate advanced web mapping technology. Each 15-minute activity in a collection is intended to be presented by the instructor from a single computer/projector classroom arrangement. No installation, fees, or logins are necessary to use these materials and software.
