This document contains scientific notation progress check questions with multiple choice answers. It asks to identify numbers written in scientific notation, compare the masses of a hydrogen atom and average human, and calculate how many times larger one mass is compared to the other. The mass of a hydrogen atom is given as 1.5 x 10-27 kg and the average human mass is 6 x 1011 kg.
