Through two investigations, life science learners determine whether or not yeast is alive. They perform tests for metabolism by providing sugar and observing if gas is produced as a byproduct. They incubate some of the sample for at...

Interestingly enough, movement is not a characteristic of living things. The first activity in a series of 20 introduces learners to the concepts of living versus non-living things and then focuses on biologists and what they study....

It's alive! Turn young biologists into mad scientists with this engaging genetics activity. Using their knowledge of chromosomes and genes, learners create dragons with unique sets of traits,...

Students influence the plant life cycle as they take care of plants.In this caring for plants lesson, students understand the parts of the plant and their functions in keeping it alive. Students participate in experiments with plants and...

Students explain how dogs evolved from wolves based on the video. For this biology lesson, students research about breeding animals for specific traits. They interview dog owners and create a presentation about the dog.

Biology classes will bubble with excitement as they complete this assignment. Beginning with an informative overview of cellular respiration and fermentation processes, the highlight comes as an experiment in determining the rate of...

A happy discovery occurred in Arkansas in 2004: a woodpecker, believed to be extinct since the 1940s, reappeared! Or did it? Middle to high school ecologists examine scientific evidence and use critical-thinking skills to determine...

Introduce the topic of astrobiology in a unit that's out of this world. Biology scholars examine the search for extraterrestrial life by culturing roundworms, a species that has been key in helping researchers understand the...

Tenth graders examine the different parts of the heart. In this biology instructional activity, 10th graders perform dissection of the fetal pig. They explain how the heart maintains homeostasis.

Students create a KWL chart about food. In this chemistry lesson, students differentiate physical and chemical changes. They explain how microorganisms are used in food preparation.

For this cell worksheet, students complete 5 word scrambles and 8 true-false questions about the characteristics of living organisms and compounds found within cells.

Fourth graders study and identify the basic needs of a variety of organisms. Terrariums and aquariums are used to demonstrate what plants, animals, and fish need to stay alive. These two classic models are used to effectively convey what...

Students investigate the various aspects associated with living things while also concentrating on their basic needs. They explore the aspects of movement and growth in plants and animals. This is done through research and other...

Students articulate in written and oral formats that bacteria can be found living everywhere. They explain in written and oral formats why the immune system is necessary. Students are presented with an opportunity to see bacteria alive...

Ninth graders share what they know about cells. In this biology lesson, 9th graders study different microscopic images of the cell. They draw one and explain to their partner why they chose that image.

Students compare the organelles present in plant and animal cells. For this biology lesson, students create an analogy to easily remember their assigned organelles. They also research their function and write a creative story.

Students analyze an animal's life cycle and behaviors, and examine what animals need to stay alive and reproduce. They develop theories and hypotheses about the reasons for migrations, using the Journey North online project.

In this biology word search worksheet, students search for 36 terms related to embryology. They check off the words as they find them in the puzzle.

Students observe that plants need air, food, light, and water to survive.  In this plant biology instructional activity, students observe the growth and development of two plants, one is the control plant and the other is denied...

For this biology worksheet, students identify and write the various species that are still present today. Then they define evolution using three words. Students also describe what a fossil is and give some examples related to a...

In this biology worksheet, students identify and match various classes of species found today. Then they explain why biodiversity exists today on earth and define evolution. Students also describe who a paleontologist is and what they do.

Students use a dichotomous key to identify unknown fictitious organisms in an assessment designed to be used after a discussion on the use of a dichotomous keys has occurred. Follow up questions about key included.

Students explore biology by completing science worksheets in class. In this animal anatomy lesson plan, students read the book The Adventures of Marco and Polo and identify the animals mentioned in it. Students examine a real life animal...
