Cells=Life!
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.
Curated OER
Plant And Animal Cells
Learners identify parts of plant and animal cells and describe the functions of each part. They distinguish between plant and animal cells. After a lecture/demo, students perform experiments which help them construct models of plant and...
Curated OER
Cell Repair and Cell Cycle
Seventh graders explore the cell cycle. They view pictures of different stages of mitosis and explain why cells reproduce. They identify the five phases of mitosis: interphase, prophase, metaphase, anaphase, and telophase.
Curated OER
The Giant Cell
After actively participating in a unit on cells, the students act out and become the organelles. They will act out and explain the functions of what each of the organelles do for the cell.
Curated OER
Cells
Students are introduced to the life cycle of a cell. In groups, they identify and describe the function of organelles. They compare and contrast the differences and similarities between plant and animal cells as well. They complete a...
Curated OER
Study of the Cell
Students draw a diagram to show the fluid mosaic model of a membrane. They explain how hydrophobic and hydrophilic properties help membranes hold their shape. They identify the functions of different cell membrane proteins as well.
Curated OER
Discovering the Structure of the Atom
Students investigate atomic and nuclear structure of matter by researching historical atomic theories. Students examine Rutherford's studies and discover that many scientific conclusions change over time as new data is collected.

Plasmolysis in Elodea Plant Cells
High schoolers microscopically observe various subcellular components. They determine the effects of different salt solutions on Elodea plant cells. Students explain the major function of a cell membrane and describe its structure.
Curated OER
Biology: Make a Model Cell
Students compare and contrast plant and animal cells and then create a model of the latter. They visit Websites to view the cells and answer questions about them. In pairs, students create cell models using plastic baggies, syrup,...
Curated OER
Algae Part One: An Introduction
Students have the opportunity to view two types of algae under 400x magnification with a compound microscope. They make observations and record their observations through drawings and words. In addition, they identify different qualities...
Curated OER
Biology: Sun, Skin and Cancer
Students identify basic components of skin on a cross sectional diagram. They provide a basic description of cancer in terms of cell biology. Students explore the ABCD of skin cancer/mole evaluation and perform their own evaluation of...
Curated OER
Onion Skins
Students 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...
Curated OER
The Living Environment
Sixth graders show what they know about plant and animal cells. In this cell project instructional activity, 6th graders get to choose a project based on their learning style. They can create a visual representation of cells, auditory...

How Genes Work Lesson Plan
Students 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.
Curated OER
Use of Microscopes and Creation of Slides
Students explore the use of microscopes and the creation of slides. They practice using, adjusting and viewing with a microscope. they view slides of familiar substances such as blood and fibers. In addition, they create slides using...
Curated OER
Mitosis and Cell Division
Students discover the processes that occur during mitosis and what makes each phase different and distinct from the others as well as how each contribute to the overall process of mitosis by looking at onion root tips under a microscope.
Curated OER
Structure of Natural Narratives
Class pairs select a prompt from a provided list and tell (and record) their story to their partner. They then examine linguist William Labov's model for natural narratives, and apply his model to their tale. Next, class members watch...
