Course Description

Description

CTY Online Programs' individually paced high school science courses help students learn complex scientific concepts using a dynamic online environment that includes graphics, animations, video, and audio-narration. Students review and apply new knowledge through interactive activities. Students use methods of scientific inquiry to learn via interactive web-based lectures and applications. Knowledge is assessed through quizzes, tests, and projects. Unit tests provide feedback and help students prepare for comprehensive midterm and final exams. The laboratory component includes both hands-on experiments using common household materials and virtual exercises. Students work with expert science educators. 

Honors Chemistry covers topics typically covered in a high school chemistry course and prepares students for Advanced Placement Chemistry.

Topics include:

  • atomic structure
  • states of matter
  • solutions
  • the periodic table
  • chemical reactions and transformations
  • chemical bonding
  • acid and base chemistry
  • energetics

CTY Online Programs Science - Comments and Feedback from Students, Parents, and Teachers

Feedback

Quotes:

"CTY's Honors Chem has effectively helped me 'clear the hurdle' in several chem topics that I initially found to be very confusing and abstract, such as bonding hybridization and equilibrium constants. I felt my instructor was a great teacher; her explanations were both thorough and really helpful."

"It was a very good course; it covered an amazing amount of subject matter in a short amount of time very effectively. I learned a huge amount of chemistry while taking this course."

"Our son has been involved with JHU/CTY for six years; CTY has been very important in augmenting his education. CTY has enhanced him not only academically, but also from visioning what he can achieve. Thank you!"
