"Measurement in Motion"

Scientists could measure the diameter of the sun before they knew its distance. Scholars construct a simple mirror box to measure the diameter for themselves. They compare this measurement with the official size, listed in a textbook,...

Young scientists design a rocket to launch using Newton's Laws of Motion in order to discover for themselves the forces of motion. 

The stage is set for you to guide future physicists through three forceful activities about motion. In the first, learners experiment with rolling carts to discover how objects interact. In the second, they inspect images of an object in...

How do you model the movement of an astronaut? The activity features software that uses an avatar to mimic movement. Groups work to determine the translation between the pre-image and the image. They then experiment with reflections in...

And they are off! Using Styrofoam meat trays and balloons, individuals build racers that demonstrate Newton's Third Law of Motion. Pupils run their racers three times and make improvements between each trial. To conclude the activity,...

Several times throughout history, groups of soldiers marching in rhythm across a suspension bridge have caused it to collapse. Scholars experiment with pendulums, resonance, and force to determine why this would happen. First, pupils...

Take a look at acceleration within the context of automotive technology. They vary the mass on a toy car and run it down a ramp, exploring Newton's second law of motion. Though this is a classic lab activity, you will appreciate the...

Take your biology class' understanding of biodiversity to a whole new level! Ecology scholars use data to calculate three different diversity indices based on the organisms in the Gorongosa National Park. The four-part activity uses an...

A substantial but viewer-friendly selection of slides presents the topics of forces and motion. The simplicity of format and content make this perfectly suited to an introductory physical science course. Slides begin by addressing...

A Newton is approximately the weight of an apple, so force is measured in apples! Apply Newton's Second Law of Motion to determine the force acting on an object.
