Diffusion Across a Semipermeable Membrane
Semipermeable membranes allow water to go through—but not larger molecules. The simulation encourages pupils to adjust the membrane pore size to understand how this works. It also provides a way to trace the movement of a single molecule.

Diffusion of a Drop
Trying to learn through diffusion rather than simply studying the material rarely works for scholars. This simulation helps make learning diffusion fun. Pupils add a drop of dye to water and observe the diffusion as the molecules bounce...

Intermolecular Attractions and Boiling Point
Why do different substances have different boiling points? Through an interactive lesson, learners explore how intermolecular attractions affect boiling points. They interact with molecules through an animation and make conclusions about...
Concord Consortium
Filling the Pool
Fill your mind with math as you think about filling a pool. Given information about the rates of two pipes, one filling a pool and one draining a pool, learners determine a piecewise function that models the volume of water in the pool...
Concord Consortium
Three Rubber Bands
Stretch your mind about triangles. Given a triangle, scholars consider a smaller triangle formed when they stretch three rubber bands from each vertex to the opposite side. They determine the ratios of the areas and perimeters of the...

Molecular View of a Solid
Why are solids, well ... solid? Take a peek inside a solid substance with an easy-to-use interactive. Science sleuths examine the motion and position of the atoms that make up a solid before drawing conclusions from their observations.

Concord Consortium: Stem Resources: Building a Bungee Jump
Students are asked to create a bungee jump that will protect a hard-boiled egg from breaking. A force sensor is needed to measure the push/pull forces on the egg. Data is inserted into force-time graphs. After completing three...
Concord Consortium
Concord Consortium: Stem Resources: Building a Zip Line
For this interactive, students plan, create, and test a zip line that will transport a hard-boiled egg without breaking it. They will make improvements on their design based on data about its performance. A motion sensor is required in...

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
Concord Consortium: Stem Resources: Confliction Selection Pressures
Investigate how selection pressures and natural selection influence populations growth with this computer model. Understand how a population changes when selection pressures are in conflict. Perform the virtual lab to see what happens to...

Concord Consortium: Stem Resources: Describing Velocity
An interactive module where students record their ideas in response to questions, and read and manipulate graphs and charts while they learn about velocity-time graphs and position-time graphs.
Concord Consortium
Concord Consortium: Stem Resources: Dew Point
For this experiment, students work to find the dew point temperature in their classroom, or the temperature at which water would condense. Includes questions for students to respond to online. Requires free registration in order to save...
Concord Consortium
Concord Consortium: Stem Resources: Earthquakes Around the World
In this interactive, students manipulate a computer model that shows where earthquakes and volcanic eruptions have occurred since 1960, to make predictions, collect data and look for patterns. Includes career connection, and a question...

Concord Consortium: Stem Resources: Electrostatics
This web-based activity takes students through a series of pages in which they find out about the effects charged particles have on one another, discover how Coulomb's force works, and see some real-world examples. Multiple-choice and...
Concord Consortium
Concord Consortium: Stem Resources: Excited States and Photons
Students are able to explore the effects of energy on excitation of atoms through simulations, then relate this information to photons at atoms' absorption and emission of light. Multiple-choice and short answer questions are found...

Concord Consortium: Stem Resources: Gas Laws
A learning module with built-in interactive features where students can read background information on each gas law, then explore the interrelationships of pressure, temperature, and volume. Covers Boyle's Law, Charles's Law,...
Concord Consortium
Concord Consortium: Stem Resources: Greenhouse Light and Temperature
An interactive tool where students can create a model of a greenhouse and use a light sensor to measure the amount of light it receives from a lamp at various times of the day. Temperature is also measured. Data is plotted on graphs,...
Concord Consortium
Concord Consortium: Stem Resources: Molecular Self Assembly
A series of science simulations exploring how molecules assemble themselves and how scientists are learning to engineer their structure. Students will discover what patterns molecules form with interactive lessons. At the end there is a...
