In this activity, students will have to design a fair race. As students discuss how to compare the speed at which each colored coating dissolves in water, they will begin to identify possible variables and suggest ways to control them. There is a downloadable activity sheet that will be very helpful to educators, and will help students stay on track. An assessment sheet is also available on the activity page to keep track of students progress. There is also a step by step guide as to how to perform the experiment, and how to introduce it t the students.
