DaVinci Biomechanics

This section encourages learning about the human body and understanding it's mechanical properties and kinetic movements.
The human musculoskeletal system is used as the learning material.
Simple drawing implements are used by the students to process the information.
Students will take home at least one sheet of paper with drawings of their lesson.
GRADE LEVELS: 5 - 9

Lesson: Synovial Joints

In this lesson, students are given a lecture about the various types of synovial joints found throughout the human body.
Simplified examples of each type of joint are drawn in a mechanical fashion.
Students draw the mechanical looking joints, step by step with the instructor leading.
Lastly, the students draw real joints by observing skeletal models as shown below.


The Science of Light, with Watercolors

This course combines art and science by creating beautifully crafted watercolor diagrams that explain the various physical properties of light. Background information for the physics and math behind each lesson will be presented to those who are scientifically inclined, along with important historical footnotes about the people who advanced our understanding about the physics of light. Students will take home intelligently designed colorful watercolor renditions of what they learned in class as they follow step-by-step instructions from the instructor in a relaxed and informal learning environment.
GRADE LEVELS: HS - College


Robotics

This expansive course introduces students to the fascinating and rapidly growing world of robotics.
There are many different technical levels in robotics, with resources & knowledge pulled in from a wide variety of fields.
The study of robotics falls squarely into the "Maker" category of learning and doing.
GRADE LEVELS: Middle School - College

The following is a partial list of the abilities and knowledge the learner experience:
~ Software Programming (RobotC, C, C++, Java)
~ Integrated Development Environments (RobotC, Arduino, Android Studio, Eclipse)
~ Microcontrollers and Embedded Applications
~ Electronics and Circuit Theory
~ Realtime Systems, Crystal Clock Speeds, Infinite Loops
~ Math: Algebra, Discrete Mathematics Series, Binary & Hexadecimal, Boolean Logic
~ Signal Processing (Analog & Digital)
~ Physics (Statics, Dynamics, Electromagnetics)
~ Art: Technical Drawing, Creative Drawing & Concepts


Circuits

This fundamental course explores how electrical circuit theory and how electrical circuits are put together. Both Analog and Digital circuits can be taught, depending upon the needs of the learner.
GRADE LEVELS: Middel School - College

The following is a partial list of the topics:
~ Voltage
~ Current
~ Resistance
~ Capacitance
~ Inductance
~ High Pass Filters
~ Low Pass Filters
~ Transistors (MOSFET IGBT)
~ Integrated Circuits (using, not designing) ~ Circuit Symbols


Electromechanical Systems

This course shows the learner how to combine different electrical and mechanical components together to create functional systems. Sensors and actuators are combined with microcontrollers to create a system that performs a task based upon programmed input or user input (or both).
GRADE LEVELS: HS - College

The following is a partial list of the topics:
~ Sensors
~ Actuators
~ Control Systems & Feedback Loops
~ User Interface Design & Implementation
~ Gears
~ Creating Prototype Circuits
~ Packaging Circuits


Gravity Well Simulator

This section will discuss gravity and allow students to do some experimentation by using a contraption that represents gravitational pull on heavenly bodies.
GRADE LEVELS: Elementary - College

Every point mass attracts every single other point mass by a force pointing along the line intersecting both points.
The force is proportional to the product of the two masses and inversely proportional to the square of the distance between them.

A gravity well is a conceptual model of the gravitational field surrounding a body in space; the more massive the body, the deeper and more extensive the gravity well associated with it.
The Sun is very massive, relative to other bodies in the Solar System, so the corresponding gravity well that surrounds it appears "deep" and far-reaching.
The gravity wells of asteroids and small moons, conversely, are often depicted as very shallow.
Anything on the surface of a planet or moon is considered to be at the bottom of that celestial body's gravity well, and so escaping the effects of gravity from such a planet or moon (to enter outer space) is sometimes called "climbing out of the gravity well".
The deeper a gravity well is, the more energy any space-bound "climber" must use to escape it.

A diagram, which may be helpful to understand how a gravity well works.

The mathematical formula for the force exerted on two masses, given their masses and distance between them.

The masses are shown with the respective positions in a gravity well, the larger mass being in the center fo the gravity well, as our Sun is.
