Investigate how and why clouds form, and what different kinds of clouds there are by following a story guiding you through a series of interactive activities. Learn about the water…
Why are there clouds? This unit explores the water cycle.
In this activity, you will use a model to study the effect of a consumer (rabbits) on two species of producers (grasses and weeds).
In this activity, you will use a computer model to observe how natural selection works when selection pressures for a trait are both positive and negative….
This interactive simulation introduces circuits with resistors in parallel and presents you with questions regarding voltage drops across resistors and currents through them in such circuits. It also covers the…
This interactive simulation guides you through the wiring of the standard breadboard and presents you with questions regarding voltage drops and currents in series resistive circuits. Use a digital multimeter…
This activity introduces circuits in which some resistors are in series and some are in parallel. Answer questions regarding voltage drops across resistors and currents through them in such circuits….
Explore the relationship between the genetic code on the DNA strand and the resulting protein and rudimentary shape it forms. Through models of transcription and translation, you will discover this…
Learn to connect position-time and velocity-time graphs. Explore velocity using an animated car icon connected to either a position-time or a velocity-time graph, or both. Then investigate other motion graphs….
In this investigation, you will figure out how to condense water from your classroom air.
