- Grades 3-4
- Science and Engineering
The human body is an amazing but sometimes gross thing. From the blood inside us to the gas that comes out, each slimy, gunky, or smelly part has a vital role to play in keeping us healthy. Why do we burp, and why does it smell? What are boogers made of? What’s in blood, and why is it so red? And why do scabs form once the bleeding has stopped?
Explore these questions and bodily functions with your peers through online discussion, anatomy and physiology mini-lessons, research articles, and short at-home experiments.
Gain a better understanding of the human body—especially those things you don’t want to discuss at the dinner table!
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).
What we'll do
Students will choose a combination of readings, videos, and hands-on projects from a "choice board” to complete independently between each session. Then we’ll meet synchronously over Zoom to compare our findings as a class. The class is ungraded, but assignments include personal reflections and a culminative presentation.
What we'll learn
- The role of a specific body system in maintaining homeostasis
- The basic activities of the digestive process and the diseases, disorders, and conditions associated with the system
- The function of the nervous system and the diseases, disorders, and conditions associated with the system
- The function of the urinary system, and the diseases, disorders, and conditions associated with the system
- The function of the immune system and the diseases, disorders, and conditions associated with the system
- The function of the integumentary system (primarily skin) and the diseases, disorders, and conditions associated with the system
By the end of the course, you will be able to:
- Design a model or experiment to test a hypothesis
- Identify and explain the structure and functions of selected body systems
- Explain how some medical treatments have changed over time
How we’ll measure learning
Students will submit write-ups of their findings online and discuss during class. This is an ungraded course, but the instructor will provide feedback on student observations and presentations.

We have concluded our financial aid application review process for Academic Year 2023-2024 Online Programs (Courses with start dates July 1, 2023-June 30, 2024). Our application for Academic Year 2024-2025 Online Programs is expected to open in January. We encourage those who may need assistance in the future to apply for aid as early as possible.
Please acquire all course materials by the course start date, unless noted as perishable. Items marked as “perishable” should not be acquired until the student needs them in the course. If you have questions about these materials or difficulty locating them, please contact [email protected].
Book Title: Grossology: The Science of Really Gross Things
Author: Sylvia Branzei
Household supplies for labs, including but not limited to:
- Gummy candies
- Pudding cup
- Rubbing alcohol
- Office supplies like: pencils, paper, markers
This course requires a computer with high-speed Internet access and an up-to-date web browser such as Chrome or Firefox. You must be able to communicate with the instructor via email. Visit the Technical Requirements and Support page for more details.
This course uses a virtual classroom for instructor-student communication. The classroom works on standard computers with the Zoom desktop client, and on tablets or handhelds that support the Zoom Mobile app. Recorded meetings can only be viewed on a computer with the Zoom desktop client installed. The Zoom desktop client and Zoom Mobile App are both free to download.
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.
