Students examine the procedure to measure current with an analog ammeter. The use of Function and Range switches is explored along with reading the needle position on the meter scale. A brief quiz completes the activity.
In this colorful, interactive object, learners examine how materials on the nanoscale compare with those on the macroscale. The focus is on the difference between macroscale and nanoscale gold in both color and melting point.
Learners follow procedures for measuring resistance using an analog ohmmeter. They examine the use of the Function Switch and the Range Switch and practice reading a non-linear scale. A brief quiz completes the activity.
