The Ratio of Surface Area to Volume
Demonstrate the ratio of surface area to volume in your high school class by using phenolphthalein, gelatin, and an onion. Intrigue the class by leading a discussion on osmosis and diffusion, then making "scientific jello." Participants...
Curated OER
Cell physiology and chemistry
Young scholars design an experiment to discriminate between chemical diffusion, osmosis, facilitated diffusion and active transport through a membrane. Be specific about predictions and interpretations!
Curated OER
Osmosis
Students 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...
Curated OER
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...
Curated OER
Protein Synthesis and Words
Young scholars explain the roles of mRNA, tRNA and ribosomes. They explain how mutations can occur in an individual. Students simulate parts of a cell to access about the process of protein synthesis.
Curated OER
What is DNA? DNA Extraction from Kiwifruit
Students isolate DNA from kiwi cells, spool DNA from a kiwi, describe role of the DNA and genes, and explain how knowledge of DNA and genes can be used in genetically modifying foods.
Curated OER
Energy, Matter, and Organization
Tenth graders review the Energy, Matter, and Organization unit. They have one week to complete an essay. Students must submit a concept map or drawing. The activity is introduces by reading a short story line which presents a simple...

Launching a Defense; Understanding the Human Immune System
High schoolers research online to answer and develop questions about immune system, create Powerpoint presentation to share information with classmates, and assimilate information into pictorial and/or graphical description of immune...
Curated OER
Launching a Defense; Understanding the Human Immune System
Students research online to answer and develop questions about immune system, create Powerpoint presentation to share information with classmates, and assimilate information into pictorial and/or graphical description of immune system.
Curated OER
Describe the Perfect Pathogen
Young scholars develop a pathogen based upon their knowledge of pathogens and after presenting it to the class, they then suggest ways that the pathogen might be combated. Next they identify possible physical or behavioral changes in a...
Curated OER
Does the Chicken have Anthrax (Explain I)
Students explain how each of the components of innate immunity function in the protection of the body. Following an investigation, they articulate how innate immunity functions.

Google for Education: Cell Biology: Filter Design and Construction
Students participate in a simulation which shows the movement of molecules across a cell membrane so that they understand passive and active cell transport. Students also use computational thinking skills by developing systems based on...

Serc: How Do Different Liquids Affect Movement of Materials Across a Membrane?
Young scholars investigate the movement of different materials across the cell membrane of a raw egg once the egg shell has been dissolved in vinegar.

Serc: Diffusion Demonstration
An interactive demonstration where students make observations of the process of diffusion. Students draw and record observations, make predictions, and make comparisons between what they're observing and how a cell membrane works.
