Deer Mouse Fur Color: From the Field to the Beach
Read the Fine Print
Educational Use
Rating
0.0 stars

In this sequence of lessons, students explore the deer mouse and its fur color and how it has evolved over time in different habitats. Students engage in the practices of science using a series of interactive computer simulations to create model(s) of evolutionary change across levels of biological organization, from molecules and cells to organisms and populations. NOTE: This sequence is designed specifically for use on touchscreen devices.

Demystifying Punnett Squares with ConnectedBio
Unrestricted Use
CC BY
Rating
0.0 stars

The goal of this activity is to demystify the science behind Punnett Squares and explore data and statistical representations in genetics and heredity. Begin by breeding two parent mice and observe the ratios in the pie chart as more offspring are bred in each litter. Compare the ratios between different pairs of parents and identify how they are different or similar. Finally, use the simulation controls to show gametes and reveal how each offspring obtained its genotype from its parents.

Diffusion Across a Permeable Membrane
Unrestricted Use
CC BY
Rating
0.0 stars

Explore how molecules can cross a cell membrane and learn about the nature of their movement. Set up the model with high oxygen and low carbon dioxide outside the cell and low oxygen and high carbon dioxide inside the cell. In which direction do the oxygen and carbon dioxide molecules move?

Diffusion Across a Semipermeable Membrane
Unrestricted Use
CC BY
Rating
0.0 stars

Explore the role of pore size in the diffusion of a substance across a membrane. Diffusion is the process of a substance spreading out from its origin. Molecules diffuse through random molecular motion. Diffusion is always happening, even when a system appears to have reached equilibrium, because molecules are always moving. Cells are selectively permeable, meaning that their membranes allow some substances to cross easily while others are unable to cross without assistance. Cell membranes are selectively permeable, in part because its pores are small, allowing the cell to prevent larger molecules from moving across the membrane.

Diffusion and Molecular Mass
Unrestricted Use
CC BY
Rating
0.0 stars

Explore the role of a molecule's mass with respect to its diffusion rate. Diffusion is the process of a substance spreading out from its origin. Molecules diffuse through random molecular motion. Diffusion is always happening, even when a system appears to have reached equilibrium, because molecules are always moving. Massive molecules have more kinetic energy than less massive molecules at the same temperature.

Diffusion and Temperature
Unrestricted Use

Rating
0.0 stars

Explore the role of temperature in the rate of diffusion of a substance. Diffusion is the process of a substance spreading out from its origin. Molecules diffuse through random molecular motion. Diffusion is always happening, even when a system appears to have reached equilibrium, because molecules are always moving. When molecules are heated, they move faster.
