Why is it important for scientists to be accurate?
Accurate means exact. It is important for scientists to be accurate because then they will get the most correct answer.

Ms. FitzPatrick wants to figure out the fastest way to get to school. For one week, she leaves her apartment at 6am and takes the bus and it takes her 30 minutes. The next week, she leaves her apartment at 6am and takes the train and it takes her 35 minutes. What is the independent variable in this experiment?
The part of the experiment that Ms. FitzPatrick changed on purpose was her mode of transportation (bus or train) and so the independent variable is her mode of transportation (whether she took the bus or the train)

What tool do we use to measure mass?
triple beam balance

Ms. FitzPatrick wants to figure out the fastest way to get to school. For one week, she leaves her apartment at 6am and takes the bus and it takes her 30 minutes. The next week, she leaves her apartment at 6am and takes the train and it takes her 35 minutes. What is the dependent variable in this experiment?
The thing Ms. FitzPatrick is measuring is the time it takes her to get to school. It changes depending on how she is traveling (bus or train). The dependent variable is the time it takes Ms. FitzPatrick to get to school.
