Cell membranes and the factors that affect its integrity are studied, with Beet tissue used as the model. A poster to display findings of the permeability of the membranes would clarify understanding and also allow a layer of language...

Use salmon eggs as a cell model for demonstrating the movement of water over concentration gradients. Junior scientists examine the same process microscopically with an onion cell. They use a thistle tube and a semipermeable membrane to...

Students define the function of the different parts of a cell. In this biology lesson, students  discuss cell structures and how its organelles perform basic functions. They differentiate between human and animal cells.

Wow! Separate organelles from the cells of dried peas. Observe vacuoles in beet cells. Watch protists in action. Examine SEM photographs. Beginning biologists get a complete exposure to the structure and function of cell organelles. Two...

Students investigate how mutations lead to changes in cell structure and function. They construct an oligonucleotide, identify a protein sequence, design a step-by-step mechanism of how they think cells repair damaged DNA, and prepare...

Identify the different stages of mitosis and what occurs in each stage with a straightforward biology lesson. Young scientists identify the importance of the cell cycle control in maintaining homeostasis, and then match the correct...

Cells of different organs have unique cell functions. Learn how cell functions vary depending on their roles in the body using an inquiry-based activity. Scholars analyze the cell structure to make comparisons to its functions, allowing...

High schoolers clarify common misconceptions about cells. They assess initial knowledge of cells and cell behavior, read and discuss an article and consider the role of cell communication in the diseases of diabetes, multiple sclerosis...

Students work with whole plant material and are not required to measure small quantities, yet they can see evidence of transformed plant cells (plant cells that have genes from bacterial plasmids). This is a laboratory suitable for...

Do you need to review animal cell structure? Investigate the ways in which different types of cells interact in a common human reflex. Your young scholars can explore the functions of stem cells, consider various illnesses and assess...

Students microscopically observe various subcellular components. They determine the effects of different salt solutions on Elodea plant cells. They detect the presence of chloroplasts, cell walls, and cell membranes of Elodea.

Students conduct a series of activities to explore the nature of cells. In this biology activity, students observe plant and animal cells under the microscope and compare them. They differentiate osmosis and diffusion.

Students work as a team to use the ProScope Digital USB Microscope and a computer to collect microscopic images from a variety of organisms. When they compare these specimens, they are able to determine how they are alike and different...

Students create analogies that help them remember the cell parts as well as their respective functions.

Create a model to study a microscopic phenomenon. The seventh of 12 lessons uses an egg (without its shell) to represent a cell membrane. Using different solutions, learners explore the concept of cell diffusion. They monitor...

Use science to solve the mystery of the Poplar murder. Pupils use forensic botany to determine if a suspect could be the killer. By analyzing images from a Transmission Electron Microscope, learners determine if the material found on the...

Students identify the main ideas of different cell theories. Using a microscope, they compare and contrast the structures and functions of prokaryotes and eukaryotes. They also compare and contrast animal and plant cells and complete...

Students explore biology by researching living cells. In this living organism lesson, students participate in a role-playing activity in which all the students in class form one plant cell by portraying specific parts of a cell. Students...

Students study cellular structures and functions.  For this cell function lesson students participate in a class discussion then make a drawing of the cell they are discussing. 

Illuminate your physics class with this examination of a photovoltaic cell. Teach the structure and operation of the device using a diagram. Then make a human-powered, larger-than-life sized model of a PV cell. Learners become electrons...

Students 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.

High schoolers create and observe coacervates. In this origin of life lesson, students create coacervates by mixing carbohydrate and protein solutions. They observe the life-like qualities of the structures and discuss the origin of life.

Students review the basic principles of plant cell structure, tissue culture, sterile technique, and cell transformation. Next students complete a plant transformation experiment using whole plant material in order to view evidence of...

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.
