Who were the key players in cell theory? Use a handout to help young biologists record the basics about cell theorists and cell types. It refers to chapter seven of a textbook, but does not include the name of the textbook. 

Pupils use high powered dissection microscopes to dissect and examine frog embryos as well as see balls of cells that were produced by rapid division. The concept of mitosis links to the lesson.

In this cells worksheet, students compare the characteristics of eukaryotic and prokaryotic cells. Students describe how different scientists contributed to the cell theory. This worksheet has 6 short answer questions and 1 graphic...

Students observe the cells of an onion by wet mounting it and viewing it in a microscope.  In this hands on instructional activity students make their own wet mount slide of an onion and are able to identify the cells in it such as,...

In this human cells worksheet, 7th graders complete a science experiment using human cheek cells. Students sketch the cells at high and lower power and label the cell nucleus, cytoplasm, and cell membrane.

In this comparing plant cells and animal cells worksheet, students view cells from their cheeks and cells from elodea. A Venn diagram reveals similarities and differences between the cells.

Objects are larger (or smaller) than they appear! Scholars use a laboratory investigation to explore the difference between resolution and magnification. The activity allows them to calculate the size of the field of view of their light...

Students discuss scientific advances brought about by the Mars Surveyor Space Program which impact on daily life, identify laboratory apparatus like microscopes, slides and coverslips, and use the microscopes to view cells and organisms.

Students measure the size of an epithelial cell and to estimate the number of epithelial cells in a given area of the body. After watching a video on cells, student groups perform an experiment using a microscope to view some of their...

Students 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 observed.

Students complete a cell biology lesson and a color lesson based on The Giver. In this biology and reading comprehension lesson set, students examine cells using microscopes. They look at the organelles and listen to How Much is a...

Students examine the cell coats (matrix) of chondrocytes and fibroblasts and observe these cells actively exclude particles which are released around them. They observe the function of the cell membrane as a gatekeeper as it prevents...

In this comparing plant and animal cell worksheet, students use a microscope to observe cheek cells and onion cells. They compare their observations and answer 3 questions about their discoveries.

Learners observe the similarities and differences between plant and animal cells. In this cell activity, students use microscopes to observe self prepared slides of animal and plant cells.

Twelfth graders investigate specialized structures in both plants and animals. They relate structure to function, as they determine why the specialization is necessary and useful to the living organisms involved. They use microscopes...

Students investigate parts of a cell. In this plant cell lesson, students determine the difference between plant and animal cells. Students discover that coral is an animal based on cell characteristics. Students create puppets to...

Students explore different aspects of stem cells.  In this human biology lesson, students complete numerous activities including reading an article and discussing it, watching a video on stem cells reproducing over time, and...

Students (females) are introduced to the cell. They discuss what a cell is, and students define what a cell is. Students comprehend that all living things are made up of cells. They comprehend that life is defined as something that...

In this how HIV infects cells worksheet, students read the given information about how HIV infects cells. Students explain the role of various structures in HIV infection. Students design a drug that might slow the rate of cellular...

Students investigate cells. They discover what cells are, where they are found, what they do and what they are made of. They construct a giant cell that is posted on the bulletin board.

Learners observe, compare and describe cell organelles in terms of their function, structure and operation. They enter and edit information in a database, build and sort a student-designed database and find records in a database.

Students experiment with photovoltaic cells and determine the energy use of their appliances. In this renewable energy lesson, students calculate the energy emitted by a photovoltaic cell through an inquiry-based lab. They keep track of...

In this cells worksheet, 9th graders identify and use a microscope to look at cells. They explain the purpose for a microscope and how to find the total magnifying power of a microscope. Students also determine what would cause an image...

Students explain how cells reproduce. In this biology activity, students explain the different stages of the cell cycle. They calculate the number of new cells produced.
