- Grades 4-5
- Science and Engineering
You and your classmates take on the role of intrepid interplanetary explorers, designing a space probe, learning about the complexity of landing an exploration vehicle, and planning a Martian colony. For decades, scientists have looked to Mars as an untapped resource, possibly holding clues to the origin of the solar system as well as the potential for future colonization. Numerous autonomous satellites and rovers have been sent to the red planet, and with each successful mission we learn more about our most accessible celestial neighbor.
Explore topics such as Newton’s Laws of Motion, Kepler’s laws, and terraforming as you learn about the atmospheric and geological conditions that exist on Mars. Utilizing this knowledge, design plans for a mission and develop a sustainable blueprint for a prosperous civilization.
Fall and Spring time commitment: 4-5 hours per week (1-hour of class time, 3-4 hours of independent work).
Summer time commitment: 12-15 hours per week (3-hours of class time, 9-12 hours of independent work).

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.
