10. A2: What way can a scientist have success when they explore and learn about the natural world?
A. going on-line for information Being on-line does not help a scientist interact with the natural world. B. completing experiments in the lab The lab setting does not necessarily help a scientist interact with the natural world. C. reading books and magazines about the natural world Reading books does not help a scientist interact with the natural world. D. observing and recording, then analyzing and communicating data collected These are all things that would help a scientist interact with the natural world.

11. Mathematics Booster 40 mL – 30 mL = 10 mL
The first graduated cylinder shows the volume of water before the lead sinker was put in. The second graduated cylinder shows the volume of water after the sinker was put in the water. Based on this information, what is the volume of the sinker?
(After volume) – (Before volume) = Volume of the lead sinker
40 mL – 30 mL = 10 mL
Volume of Lead Sinker = 10 mL
