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...

Unleash the power of ... blackberries! Science superstars create solar cells using the juice of berries or leaves of a citrus tree in an engaging lab. In addition to offering a plethora of resources, the teacher's guide gives background...

With rising oil prices and increasing concerns over global warming, the pressure is on for engineers to develop alternative sources of energy. Among the new technologies being developed are hydrogen fuel cells, which young scientists...

Students examine how living cells reproduce to make new cells.  In this cell reproduction lesson students complete a lab activity and answer questions. 

Students examine the behavior of living cells treated with different types of stimuli. They watch an online movie, examine wet mount slides under a microscope, take an online quiz, and analyze data.

In this science worksheet, students calculate the size of different samples using the microscope as part of a formal lab assignment.

Intended to supplement your existing cell function and organelle lessons, pairs work together to develop a real-world analogy for cell structures. In addition to writing paragraphs about the comparison, each group will make a short...

Lab groups fill a section of dialysis tubing with glucose and starch solutions and suspend it in a water bath. They use iodine as a starch indicator and a glucose test strip to find out if either of the materials crossed the selectively...

A thorough investigation of cell transport is provided when completing the assignment. The first half requires biology class members to answer questions about diffusion and osmosis with the aid of diagrams. Then they fashion an...

Young scholars 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...

Just because we can't see it doesn't mean it isn't there! A growing concern for environmental scientists is toxic nanoparticles in our air and water. Young scholars conduct an experiment to demonstrate how these particles can cross our...

Third graders, in groups, make a model of a plant or animal cells and represent each of the organelles in the cell.

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.

Students explore epidermal cells. After following specified procedures for removing epidermal cells from their wrist, students view the cells with the use of a microscope. After creating a drawing of their observation, students label the...

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.

A seventy-two slide PowerPoint that reviews several lab explorations done in an AP Biology course. For each lab there is a description, concepts, and conclusions. Many pictures and graphics make this visually appealing, but it would not...

Young scholars participate in a review of diffusion and the basic properties of the cell membrane before exploring the process of osmosis in a lab activity. Using shell-less eggs that have soaked in various solutions, students make...

Searching for simple ways to teach mitosis to high schoolers? Using colored chalk and onion root tips, pupils visually demonstrate what they view when looking through the lens of a microscope. There are also various ways to expand the...

You may find this presentation helpful in setting up the classic experiment where potato wedges are used for observing the effects of osmosis. You can view the experimental setup in the text and a lab sheet in the pictures, but you will...

Lead your biology class on a cell-sized adventure! Emerging scientists construct models of prokaryotes, then design an experiment to properly grow a bacterial culture. They conclude the activity by viewing the culture under a microscope....

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

High schoolers explain how sunlight is converted to electricity. In this series of physics instructional activity, students study how varying the characteristics of the light source affect photovoltaic cells. They research their...

In this plant and animal cell learning exercise, students draw five examples of plant or animal cells that are specialized to perform a particular functions. They also complete 6 short answer questions based on their observations.

Students discuss what comes to mind when they hear the term cell and discuss what a cell is in biological terms. They look at pictures of cells and color a picture of a cell diagram, writing the job of each part as they go. After the...
