- Grades 3-5
- Science and Engineering
Discover the role that chemistry plays in your everyday life in this experiment-intensive course. Through hands-on chemistry activities, you’ll learn about the states of matter, explore different types of mixtures (and make your own!), and learn about subatomic particles and building atom models. As you continue your focus on chemistry in the kitchen, you’ll witness endothermic reactions in a bread-baking activity and learn about enzymes, fermentation, and food preservation with related at-home labs. Additionally, you’ll review the properties of water; chemical reactions and biological molecules; acids and bases; polymers; colors and pigments; biochemistry; and other relevant concepts.
Time Commitment: 3-6 hours of independent work per week.

About Science and Engineering at CTY
Our Science and Engineering courses bring a variety of science topics to life. By introducing topics not covered in standard science curricula, we build and reinforce your science knowledge. All courses support critical thinking, problem solving, and reasoning, and encourage a real-life, hands-on approach to learning about Earth, space, life sciences, chemistry, and the physical world. Guided by expert CTY science educators, you’ll master science lab kits, perform hands-on experiments using common household objects, participate in dynamic group discussions, or prepare for AP exams.
Newly revised Honors Physics course
Our completely redesigned Honors Physics course features new lessons, conceptual and problem-solving videos, and guiding questions that teach students how to solve each type of problem. Hands-on exploration activities challenge students to solve everyday physics problems from how giant cruise ships stay afloat to how to ship fragile packages without them breaking. Putting their physics knowledge to the test, students compete in our catapult design competition for Furthest Launch and Creative Design awards.
More engaging science enrichment courses!
In the newly revised Inventions in Engineering course, students bring fantasy into reality by creating inventions to solve the problems of favorite fictional characters and the real world alike. A new unit in Introduction to Forensics asks students to evaluate the validity of various kinds of forensic evidence and its impact on the lives of individuals, and to provide recommendations on which types of forensic evidence should be admissible in the criminal justice system. In Household Chemistry, students engage in newly revised activities that help develop their skills in making and recording detailed observations using all 5 senses as they explore states of matter and the role chemistry plays in their daily lives.
