Course Description


In this course, students are introduced to the role played by chemistry in their everyday lives. Students learn about the states of matter, the changing states of matter, and colligative matter through ice melt and the freezing point of ice in laboratory investigations. They explore different types of mixtures and then make their own mixture – salad dressing. Students learn about subatomic particles and build models of atoms. They witness endothermic reactions in a bread-baking activity. During this focus on chemistry in the kitchen, students learn about enzymes, fermentation, and food preservation by doing hands-on activities. Additionally, students learn about the properties of water, chemical reactions and biological molecules, acids and bases, polymers, colors and pigments, and other concepts. Throughout the course, laboratory investigations, hands-on activities, and discussions deepen students’ understanding of the course concepts. This course does not have any synchronous class meetings, but students may schedule one-on-one virtual meetings directly with the instructor to answer questions or concerns.

  • States of Matter
  • Mixtures
