A very important outcome of studying science is to acquire the ability to make and interpret observations. Students initially observe and describe seven different solutions. They then combine pairs of these chemical solutions and use their observations to determine whether or not a chemical reaction took place. Finally, they test an unknown solution and use their previous observations to determine the chemical composition of the unknown.
