Well, well, well, another exciting day in science class. We discussed our homework, which included the concept of mass and weight--what is the difference? The difference is that weight is the force of gravity acting on mass. Your weight can change, but your mass remains the same regardless of where you go. We also discussed volume measurements, noting that cubic centimeters (cc) are used for solid volume while milliliters (ml) are used for liquid volume. One cc is equal to one ml.
We next started learning about significant figures (sig figs) by watching the worlds greatest sig fig video. Here it is for your viewing pleasure:
Enjoy!
Sweet justice.
