On Wednesday this week we took our first real test. It required alot of study if you wanted to do very well on it and who wouldnt? But there were some questions on the test i didnt know, but i took an educated guess. These were the questions:

What is the PH of battery acids?

Which one of the following is not a scientific base unit
A. Second
B. Meter
C. Feet
D. Kilogram

I also thought the base unit question were challeging. You just had to remember the saying:
