Seventh graders describe the stages of mitosis. In this biology lesson, 7th graders explain the importance of cell division. They complete an activity packet at the end of the lesson.

Learners explore the structure of a plant cell. They carefully peel a single layer of onion skin from a slice of onion and stain it with methylene blue to observe the structures inside. They use a Digiscope connected to a computer to...

For this cells learning exercise, students answer questions about the first person to see a cell as well as the evolution of microscopes. They define the parts of a cell and tell the differences between Prokaryotes and Eukaryotes. There...

Fourth graders create analogies in poster format between a cell's organelles and their school. For example, 4th graders coul say a cell's mitochondria is like the cafeteria, both are a source of energy.

Students define attributes of human chromosomes and match them to make a human karyotype.  In this investigative lesson students demonstrate how traits are encoded in genes found on chromosomes.

For this internal systems and regulation worksheet, students correctly decide if given statements are true or false. Students apply information learned about the circulatory system to the given statements to determine statements of truth...

Learners define the key terms that are the structure and function of DNA. In this genetics lesson students complete a lab activity in which they construct a model DNA structure.

Students examine inheritance of blood types.  In the chromosome lesson, students create a model of chromosome and predict the blood type of offspring.

In this sponge worksheet, learners read about the different parts of a sponge and answer 20 short answer questions that follow. They color and label different sponge drawing.

Fifth graders, in groups, create a plant or animal cell out of cookies, frosting, and candy pieces.

Students identify the difference between eukaryote and prokaryotes and examine the structure of bacteria.  In this bacteria lesson students examine the different ways that bacteria are classified through an activity. 

Young scholars investigate the biology of ADHD and its implications upon the formation and treatment of the disease. They draw and label the parts of a neuron. Also, they describe the neurotransmission cycle. Students create a list of...

In this bacteria worksheet, students read several elements of bacterium cells, their diet, types, locations, reproduction, resting stages, effects of, and classification. Students also study a cross-section of bacterium cells.

For this fertilization worksheet, students complete 10 short answer questions about the phases of fertilization then place 6 events of fertilization in the appropriate order on a timeline.

This plant biology PowerPoint introduces plant parts and their functions. This PowerPoint allows students to identify each plant part on a diagram, along with its' function. The slides contain a clear explanation of how each plant part...

In this biology worksheet, students watch a series of videos and complete 10 short answer questions right after. They explain how ART drugs interrupt the life cycle of HIV.
