Escape! Survival of the Fittest Grasshopper
Fourth graders, in groups, design a paperclip grasshopper. They determine its ability to survive a prey by jumping high, far, or with a distracting behavior.
Curated OER
Squirrel Challenge
Students utilize The Nature Park Adventure educational software program to Introduce Modelling, Including the Estimation of Angles.
Curated OER
Wind Gauges
Students use FoilSim interactive software to become familiar with the way in which the flow of air across or around an airfoil affects its ability to create lift.
