Curated OER
Osmosis and Diffusion
In this science worksheet, students investigate the cell and the process of osmosis and diffusion across the cell membrane and then perform an experiment.
Curated OER
Diffusion
High schoolers are asked how does odors move around without energy? They relate concentration gradients, diffusion, and equilbrium and predict water movement into and out of cells. Students are shown a demonstration where the teacher...
Curated OER
Osmosis
Pupils explore diffusion and active transport. They observe the effects of eggs in vinegar and predict what will happen when eggs are placed in corn syrup with food coloring. Students complete worksheets which lead them to describe the...

An Egg-cellent Osmosis Experiment
Learners 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...
Curated OER
Diffusion & Osmosis with Data Analysis
Learners explore principles governing diffusion and osmosis. Students perform a dialysis tubing experiment. They obtain core samples of potato in varying concentrations of sugar-water to measure water potential of the potato cells....
Curated OER
Do Salt Water Fish Drink?
Students conduct an experiment with potato cores and a sucrose solution to investigate how salt water fish process water. They develop a lab report of their experiment.
Curated OER
Making Hypotheses
Fourth graders practice making hypotheses about what they believe occur as they perform an osmosis experiment in class. This experiment is designed to illustrate how important it is to make an accurate hypothesis.
Curated OER
What Is an Egg Without its Shell?
Middle schoolers observe osmosis, a cellular process that normally can't be observed without a microscope, and use scientific method to observe osmosis in a chicken egg.
Curated OER
EggCELLent Diffusion
Students examine and discuss the concepts of diffusion and osmosis. They observe the effects of diffusion on eggs by recording the change in an egg's size and the amount of liquid substance that remains.
Curated OER
2D Animation of Cellular Processes
Students create an animation of a cell process and insert it into a presentation. They choose a cellular process such as mitosis, osmosis or DNA replication, and create a simple 2D animation.
Curated OER
Diffusion
In this diffusion worksheet, high schoolers review the terms associated with diffusion and osmosis plus answer questions based on a passive transport lab they completed. This worksheet has 8 short answer questions.
Curated OER
The Cell Theory
In this cells worksheet, learners review how the cell theory was developed. Students review the structure and function of cell structures and active transport. This worksheet has 30 fill in the blank questions.
Curated OER
Diffusion an Osmosis
In this crossword puzzle worksheet, learners read the clues that relate to diffusion and osmosis. Students then complete the 20 question crossword using the given clues.
Curated OER
Active Transport
In this active transport worksheet, learners review the cellular process of active transport including the structures and functions of the cell organelles involved. This worksheet has 28 fill in the blank statements.
Curated OER
