I have never learned so much about the ear and hearing before. Even after a very lengthy Biology course that we did last year!
The Sound Global Topic covers such topics as Sonar, how the ear works, how musical instruments work, how sound travels and more. As a parent who has taken a class on sound and music in college, I was impressed by the material for thIs Global Topic.
To give you an idea of just how in-depth this program is, here are the subject areas listed for the Fluid Dynamics GT:
Aerodynamics, Hydrodynamics, Bernoulli’s Principle, Vortices, Turbulent and Laminar Flow, Daniel Bernoulli, Orville And Wilber Wright, Ailerons and Their History, Kingfisher Hydrodynamics, Penguin Hydrodynamics, Dolphin Hydrodynamics, Fin Types and Swim Patterns, Bird Flight, Bird feathers, Insect Flight, Avian Lungs, Box Fish Swimming, Animal And Insect Drinking, Shark Denticles, Nose Turbinates of People and Animals, Cavitation, Cavitation and Ship Propellers, Cavitation Erosion, Mt. Saint Helens, Cavitation and Sedimentation, Air Foils, Hydrofoils, Venturi’s, Rocket Aerodynamics, Carburetors, the Space Station, Piezoelectricity and more.
I simply love the whole "crosswiredness" with this program. Because there is so much packed into these topics that touch on many different subject areas to insure a concrete understanding of the topic being taught. It's perfect no matter what your learning style is. And the Christian worldview presents the world so beautifully as we learn the power behind God's creation.
Fair warning – there is a LOT of material but it is intended to be completed at a pace that is comfortable for the student.
