Dive into the world of mixtures with this engaging lesson on the differences between heterogeneous and homogeneous mixtures. Discover how substances can be separated using various methods such as evaporation, distillation, decantation, floatation, magnetism, and filtering. Students will participate in sorting activities and learn why it is essential to understand how to separate mixtures. An interactive assignment challenges students to draw examples of both types of mixtures and explain the separation process. Get ready to become a mixtures expert!

Review: A substance contains one type of matter. A mixture is a combination of substances. Homogeneous mixtures are the same throughout. Heterogeneous mixtures have substances that stay separate. Mixtures substances can be separated again.

Assignment: Draw one heterogeneous mixture and one homogeneous mixture. Write why they are that type of mixture and how you might separate the substances.
I had fun learning and working with you today! Keep your eyes open, scientist! I will see you next lesson.
