Early on in the study of physical science, students must grasp concepts associated with the periodic table. A perfect way to introduce periodicity and periodic groups is by using paint chip color samples. The color progression (red-orange-yellow-green-blue-purple) resembles the periodic properties on the table, and the color shade (light to dark) resembles the trends within the groups. This inquiry-based, hands-on lesson is sure to help students learn about one of the key concepts of basic chemistry.
