Use the Sound Grapher to create visualizations of sound and learn about the frequency, wavelength, amplitude and velocity of sound waves.

In this activity the temperature of a reaction is monitored for different concentrations of reactants.

Repeated motion is present everywhere in nature. Learn how to 'make waves' with your own movements using a motion detector to plot your position as a function of time, and try to duplicate wave patterns presented in the activity. Investigate the concept of distance versus time graphs and see how your own movement can be represented on a graph.

Monitor the temperature of a melting ice cube and use temperature probes to electronically plot the data on graphs. Investigate what temperature the ice is as it melts in addition to monitoring the temperature of liquid the ice is submerged in.

In this activity, students interact with 12 models to observe emergent phenomena as molecules assemble themselves. Investigate the factors that are important to self-assembly, including shape and polarity. Try to assemble a monolayer by "pushing" the molecules to the substrate (it's not easy!). Rotate complex molecules to view their structure. Finally, create your own nanostructures by selecting molecules, adding charges to them, and observing the results of self-assembly.

Students will preform three mini-lab activities with no previous knowledge of Newton's laws of motion. Each lab activity demonstrates one of Newton's laws of motions. Students will write their observations from the three mini-labs and then use these observations later to connect which lab went with which law of motion, after the teacher formally introduces Newton's Laws of Motion.

Students will investigate potential and kinetic energy, and observe that energy is continually transferred from one object to another between various forms.This module was developed by Christina Owens as part of a Virginia Commonwealth University STEM initative sponsored by the Virginia Department of Education.

How does energy flow in and out of our atmosphere? Explore how solar and infrared radiation enters and exits the atmosphere with an interactive model. Control the amounts of carbon dioxide and clouds present in the model and learn how these factors can influence global temperature. Record results using snapshots of the model in the virtual lab notebook where you can annotate your observations.

Measure relative humidity in the air using a simple device made of a temperature sensor, a plastic bottle, and some clay. Electronically plot the data you collect on graphs to analyze and learn from it. Experiment with different materials and different room temperatures in order to explore what affects humidity.

Investigate what makes something soluble by exploring the effects of intermolecular attractions and what properties are necessary in a solution to overcome them. Interactive models simulate the process of dissolution, allowing you to experiment with how external factors, such as heat, can affect a substance's solubility.

Overall goal of the module (reference: The standards that reflect intended Enduring Understanding)The student will:A.)  model a longitudinal (compression) wave and diagram, label, and describe the components (wavelength, compression, and frequency) (PS.6 a)B.)  explain the relationship between frequency and wavelength (PS.6 a)C.)  plan and conduct an investigation related to sound (the investigation may be a complete experimental design or may focus on systematic observation, description, measurement, and/or data collection and analysis) (PS.6 b)This module was developed by Tracey Nipper as part of a Virginia Commonwealth University STEM initiative sponsored by the Viginia Department of Education.

In this 8th grade physical science module, students will calculate speed problems/scenarios using the speed equation (speed=distance/time), and compare and contrast the speed of multiple objects.  This module was developed by Tracey Nipper as part of a Virginia Commonwealth Universtiy STEM initiave sponsored by the Virginia Department of Education.    

Lesson Length: 1-2 hoursGrade Level: 6-8Students build a water filter with a variety of natural and commercially produced materials. First they test the materials and then choose which to layer together themselves based on material performance. Students learn about water resources and engineered supports for the earth’s water systems and the impacts on environmental and human health. Engineering connections are highlighted throughout the lesson. Special thanks to Giles County, VA STEM Coordinator, Christina Martin, whose unit on The Global Water Crisis was the inspiration for this lesson. Also thanks to the NASA Water Filtration Challenge (https://www.jpl.nasa.gov/edu/teach/activity/water-filtration-challenge/) that helped guide Christina in the development of her lesson.This material is based upon work supported by the National Science Foundation under Grant No. 1657263.

Lesson length: 1-2 hoursGrade level: 6-8Students practice using the scientific method as they engineer methods to fix damaged mountain roads. Using engineering design thinking, students assess the problem(s), develop strategies for addressing them, budget for repairs, and create and test prototype solutions.This material is based upon work supported by the National Science Foundation under Grant No. 1657263.

Lesson Length: 1-2 hoursGrade Level: 6-8Students learn about relationships between earth and space including elements of our solar system, gravity, escape velocity, and space exploration though a breakout box experience. They solve clues about space and conditions needed to support life on a planet and perform tests related to space travel. Clues for opening locks on the breakout box are purposefully challenging to simulate the struggle engineers often grapple with when problem solving.This material is based upon work supported by the National Science Foundation under Grant No. 1657263.

Windmills have been used for hundreds of years to collect energy from the wind in order to pump water, grind grain, and more recently generate electricity. There are many possible designs for the blades of a wind generator and engineers are always trying new ones. Design and test your own wind generator, then try to improve it by running a small electric motor connected to a voltage sensor.
