Maria would like to determine how mixing two solutions that chemically react with each other affects the density of the solutions.
Maria hypothesizes that the solutions will increase in density. Maria tests her hypothesis by:
1. Selecting the solutions to test.
2. Pouring the solutions together.
3. Measuring the density of the solutions after the
chemical reaction has taken place.
4. Recording her results.
What is wrong with how Maria tested her hypothesis?
the solutions
