Concord Consortium: Stem Resources: Changes in the Environment
An activity to help students understand that as the environment changes, plants and animals must evolve to stay alive. Students watch as a mystery plants grow in a changing environment to see if they will evolve or go extinct.

Concord Consortium: Stem Resources: Diffusion, Osmosis, and Active Transport
Have you ever wondered how important gases enter and leave cells? Take an up close tour of a pore in a cell membrane. Then explore diffusion, osmosis, and active transport through this collection of interactive models.
Concord Consortium
Concord Consortium: Stem Resources: Natural Selection
Build a dam in the middle of an ecosystem and observe how the population of plants and animals adapt to their new environment with this science simulation. Learn how the populations adapt to survive in their new habitat. Then remove the...

Chem Collective: Osmotic Pressure
When a balloon is filled to near bursting with SF6 is left in air, it will often burst after a period of time. This is because the smaller N2 molecules diffuses into the balloon while the larger SF6 molecules remains causing the balloon...
Carnegie Mellon University
Chem Collective: Brownian Motion
Particulate level simulations that show only solute particles are convenient, since they focus student attention on the molecules of most interest. However, such solute molecules move in a Brownian manner. This simulation helps students...
Carnegie Mellon University
Chem Collective: Chemical Potential: Staircase Demonstration
As we look for connection points across disciplines, we are increasingly drawn to chemical potential as the connection point. This simulation shows particles thermally distributed on a staircase. A linear increase in energy leads to an...
Carnegie Mellon University
Chem Collective: Dna Binding Dyes Scenario
This activity explores the equilibrium of dyes that self-assemble into DNA templates. Students use knowledge of equilibrium and quantitative spectroscopy to explore different dyes that bind selectively to DNA molecules. In this activity,...
