Effect of Size on Uptake by Diffusion
Cell size is limited by the surface area to volume ratio, but why is this true? Scholars measure the surface area and volume of cubes before placing them into liquid. After a set amount of time, they measure the uptake by diffusion for...

Sizing Cells
High schoolers examine how living cells reproduce to make new cells. In this cell reproduction lesson students complete a lab activity and answer questions.
Curated OER
Cell Size Changes
Learners 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.

Modeling Limits To Cell Size
Students participate in a 'hands-on' activity that simulates the changing relationship of Surface Areas -to- Volume for a growing cell. They assemble models of cells for comparison.

Cell Reproduction
In this cell reproduction worksheet, students will discover that when a cube doubles in size, the surface area grows by four times and the volume grows by eight times. Students will use this information to understand the limits to cell...

Curb the Epidemic!
Class members use an applet on the Internet to simulate the spread of a disease. The simulation allows individuals to determine two nodes to vaccinate to limit the number of nodes infected. By running several simulations, scholars can...
Curated OER
Maximum Power Point
Students investigate how to optimize the power output of a photovoltaic cell using a home-made gnomon stand. They use data collected to create current-voltage and power-voltage curves to determine the "maximum PowerPoint," (MPP) at which...
