Updated on 4/19/19. 10 versatile mini-assignments to help students fully understand the differences between elements, molecules, compounds and mixtures.
These assignments can be used as warm-ups, exit cards and/or short quizzes.
Students are given the following vocabulary, along with a periodic table, to help them learn about different ways we classify matter in addition to other introductory lessons. A printable student page of these words is provided.
