MODULE 07 / MEASUREMENT AND METHOD

Lab Bench

Real lab work, virtually: choose your equipment, take your own readings, record a notebook, and report a result with an uncertainty.

3 labs ready

These labs are about measuring, not about getting a known answer. The physics is exact, but your readings are not: you time the drops yourself, read the scales yourself and mark the video yourself, just as in a real lab. A good result is a sensible value with a sensible uncertainty, and an explanation of what limited it.

Lab 1Practice · graded

Find g

Drop a steel or ping-pong ball, time it by hand or with an electronic timer, read the height off a measuring stick, and find g on Earth or on your own mystery planet.

g from a projectile

Fire a ball from a spring launcher, film it, calibrate the video and mark the ball frame by frame, then fit the motion yourself to find g.

k from a spring

Hang masses on a spring and read the stretch, then set it oscillating and time it by hand or with a motion sensor. Find k both ways and compare them.

Graded assignments

Assign and grade Labs 1–3: make a link for a graded assignment (each student gets their own hidden planet or springs), post it in Canvas, then paste the completion codes students submit to get scores and a CSV for the gradebook.
