In this demonstration activity, students make structural models of gas molecules using pipe cleaners and polystyrene balls and test their molecules for their resonant frequency. Students shake the models, count vibrations, and compare the resonance... (View More)

In this activity, learners select the scientific instruments for their satellite, calculate the power requirements for all the subsystems, and construct a scale model of their very own Earth observing satellite using building blocks and/or Legos.... (View More)

Students create a physical model illustrating soil water balance using drinking glasses to represent the soil column, and explain how the model can be used to interpret data and form predictions. Using data from the GLOBE Data Server, they calculate... (View More)
