Young scholars read examples of behaviors in various animals. They design an experimental question about the behavior. They explain if the question involves the proximate or ultimate level of causation.

High schoolers use microscopes to study live fish embryos and animated diagrams of cell division on the Internet. They see that scientists rely on technology to enhance the gathering and manipulation of data. They create web pages on...

Students compare the evolution theories of Lamarck and Darwin. They use self-assessment and a video to increase their knowledge of evolution theories. They research questions and present them to the class.

Here is a fine biology lesson that introduces youngsters to reptiles. They study their feeding habits, their habitats, and the adaptations they must make to survive in their environments. The outstanding lesson includes two excellent...

Seventh graders compare/contrast the life cycles of free-living organisms to that of parasites. They conduct Internet research, illustrate the stages of a specific organisms's life cycle, and direct and produce a mini-video production.

In this flatworm body plan activity, students compare the body plans of several worms. Students answer several questions based upon the given diagrams of a cross section of the different body plans of each worm.

Young scholars examine animal and plant cells using a microscope and participate in a class discussion about the functions of the organelles.  In this biology lesson, students use microscopes and videos to better understand the...

In this food chains worksheet, students identify the producers and consumers in the given food chains and describe how contaminants can biologically accumulate. This worksheet has 4 short answer questions.

Young biologists piece together the puzzle of the human body with this simple anatomy activity. Presented with a picture of the human skeleton, students are challenged with the task of correctly identifying the 27...

Take mitosis and meiosis out of the biology textbook and onto the screen! An innovative class project prompts young biologists to create an animation movie using clay, showing the phases involved in mitosis or meiosis by...

High schoolers take measurements of the distance between the objective and the slide when in focus with each objective. They determine the diameter of the field of view at each power in order to determine the size of the cells being...

Explore 1870s when a "bone rush" led to amazing discoveries, as fossil-hunters risked life and limb in their quest for dinosaur remains. The class uses the attached visual encyclopedia to prep for a discussion on early paleontology. Two...

A multi-faceted lesson immerses AP biologists into the world of the stem cell. Using PowerPoint presentations, you introduce your class to diabetes and the possibility of finding cures through stem cell research. Online animations and...

Third graders demonstrate the effects of varying environmental components on plants and animals: chemical, physical and biological characteristics of a habitat. They find chemical, physical and biological characteristics of the lake at...

After removing the shell from a raw egg, cell biologists soak the egg in either a hypotonic, hypertonic, or isotonic corn syrup solution. They calculate the percent change in mass and compare it to the strength of the solution in a...

What's the link between lactase persistence and dairy farming? Biology scholars analyze data to find evidence of the connection, then relate this to human adaptation. Working individually and in small groups, learners view short video...

Winogradsky columns are ideal for observing the role of bacteria and other microorganisms in an ecosystem. This student activity guide is complete with data tables for observations and analysis questions for processing what was observed....

Here is a well-designed science instructional activity that shows learners that everything that organisms do in ecosystems, including running, breathing, burrowing, growing, requires energy. After a thorough discussion of their own...

Biology pupils take the cell membrane apart piece-by-piece as they complete this worksheet. They describe the structure of the cell membrane and explain the processes that transport materials across it. This phenomenal resource even has...

From the light reaction to the Calvin cycle, this presentation contains information about the various stages of photosynthesis.  This is a great supplement to some of the biochemistry-heavy presentations about the specific...

As your class views each slide, they will be introduced to the organelles and structure of the cell.  Details about structure and function are given and also some trivia about their frequency and population. There is also some...

Young oceanographers research deep sea corals that thrive on chemosynthesis. The instructional activity focuses on the biology of the animal, preferred habitat, associations, and interactions.

Inform your class about the adaptations in fish eyes: cones, lens size, endothermy, and speed of vision. The adaptations are related to diving behavior. Junior marine scientists compare the adaptations of four different fish species to...

Learners study binomial nomenclature and museum-based research. They create a curiosity box, label the objects in their curiosity box , develop a classification scheme for the objects, and create a database of all objects collected by...
