dissolve when the temperature of water is highest, while the
other student thinks more salt will dissolve at lower
temperatures.
Which statement describes a scientific approach to their two
predictions?
A. Develop a compromise since the two students disagree.
B. Measure the solubility of salt, sugar, and baking soda in
water.
C. Measure the solubility of salt in water at several different
temperatures.

Students gathered data to analyze their water
consumption. The table shows the range of
averages for the class. The students discussed the
data to reach conclusions
Which statement from their discussion describes
skepticism about the data?

supports the data she collected.
B. Faith concludes that taking showers conserves
more water than taking baths.
C. Neely wonders if the dishwashing data is
accurate since the range is so large.
