Learners view illustrations showing the direct dependence of the volume of a gas on temperature and consider the relationship between the Kelvin and Celsius temperature scales.
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.
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.
UP FROM SLAVERY (Chapter 6) by Booker T. Washington
I ... wondered if there was a white institution in this country whose students would have welcomed the incoming of more than a hundred companions of another race in the ... way that these black students at Hampton welcomed the red ones.

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.
Cilj ovog kviza jest ponavljanje gradiva dur i mol ljestvica koje smo do sada obradile (C-dur, a-mol, G-dur, e-mol, F-dur, d-mol), kao i nekih općenitih činjenica koje vrijede za sve ljestvice.
