Cellular Soap Opera - Soap Films Can Behave Like Membranes
Soap, suds, and cell membranes. Pupils create a model of a cell membrane by using soap films. They experiment with trying to pass different objects through the film without popping it. Using a tube, they create a passageway through the...

Introduction to Osmosis
A chicken egg is a very large cell—perfect for investigating osmosis! Scholars conduct an experiment with vinegar and eggs that helps them understand the process of osmosis. They follow the activity with an in-depth look at osmosis in...

Osmotic Pressure: Spontaneous Balloon Popping
Visualize osmosis using an interactive activity. As learners monitor a simulation, they witness the particle movement through the membrane. A balloon represents the cellular membrane and 'pops' as osmosis creates an imbalance of particles.
Concord Consortium
Diffusion Across a Permeable Membrane
Oxygen and carbon dioxide freely cross cell membranes. The simulation demonstrates the diffusion of these across a permeable membrane. To create a great visual for users, it graphs the balance of molecules as it changes throughout the...
Concord Consortium
Diffusion Across Semipermeable Membranes
Mitochondria use two semipermeable membranes to work properly. Young scientists adjust the pore size for two membranes. They then observe the diffusion of two different sizes of molecules.
Concord Consortium
Diffusion Across a Semipermeable Membrane
Semipermeable membranes allow water to go through—but not larger molecules. The simulation encourages pupils to adjust the membrane pore size to understand how this works. It also provides a way to trace the movement of a single molecule.

Cell Membrane Color Sheet and Build a Cell Membrane
A cell of another color is still a cell. Pupils color a cell to identify its structures in the fourth segment of a seven-segment series. Groups work together to build a three-dimensional cell membrane segment, which is combined with...

Transport Across the Membrane
Take your biology class on an exploration of the inner workings of cells with this multimedia presentation. Looking closely at the structure of cell membranes and the processes of osmosis and diffusion, this resource explains for...
Curated OER
Diffusion through Membranes
Students identify diffusion and its processes through experimentation and calculations. They also use a CBL and conductivity probe to measure the conductivity of various solutions and study the effect of concentration gradients on the...

Osmosis and Diffusion: Egg Lab
Students examine why diffusion and osmosis happen in an egg cell. In this diffusion lesson students demonstrate a semi permeable membrane.

Hidden Words
In this wordfind worksheet, students circle the hidden words on the list as it relates to hen eggs and chicks. Students write the message about chicks and the eggs that incubate them until hatching.
Curated OER
Smelly Balloons
Students investigate the concept of diffusion through a membrane. They do this through the conduction of a simple experiment. Students make observations while determining if the smell of different chemicals seeps through the balloon...

Review of Cell Respiration
For this cellular worksheet students complete a series of multiple choice questions on cell respiration, proteins and photosynthesis.

Selling Cells: a Study of Organelles and Cell Structure
Students study cellular structures and functions. In this cell function lesson students participate in a class discussion then make a drawing of the cell they are discussing.
Curated OER
Cell Structure And Function
In this biology worksheet, students respond to 13 multiple choice questions related to cell structure and function. They identify which are microfilamets and which have a cell wall. Students also describe what chloroplasts are and their...

An Egg-cellent Osmosis Experiment
Students investigate the problem of osmosis by conducting an experiment. They use eggs with the shells dissolved to tell whether fluid can move across the membranes. The experiment provides high interest for all kinds of students to keep...

Plant Cell Coloring
Students study a plant cell and its parts. In this cell organelle lesson students are to label parts of a plant cell and color them.
