Academic Challenge: Newtonian Physics
Big thanks to everyone who entered the inaugural Academic Challenge. These are projects and guides that will help teachers help their students understand Newtonian Physics. The next Academic Challenge will be Elementary Art, so sharpen those pencils and get out the good scissors.

Proud Winner of Sugru, a t-shirt, and 1 year of Pro Notes: This was a great example of a difficult-to-illustrate concept brought to life with an easy demo. Plus, magnets are awesome.

Complete the challenge as specified above and share a link for a Guide or Step-By-Step Instructable in the comments below.
OPEN TO US, CANADA (excluding Quebec), UK and AUSTRALIA (official rules)

Rules:
1) You MUST post either a Step-By-Step Instructable or Guide
2) All Step-By-Step Instructables MUST have at least 3 steps and full photo documentation. All Guides MUST include at least 4 projects and explicitly connect the projects listed to the academic standards below.
3) There is no limit to the number of Instructables you can post. However, no duplicate entries are allowed.
4) Projects that do not meet the criteria of the challenge will not be permitted to enter.
5) The judges reserve the right to disqualify anyone who cheats or engages in unsportsmanlike conduct.
6) To be clear, the project MUST be published after the challenge has started to be eligible.
(see the official rules here)
Deadline:
All entries must be published and posted in the comments below posted by 11:59pm February 7, 2012 PST/ 7:59am February 8, 2012 GMT.
Judging:
All entries will be exclusively judged by Wilgubeast based on successful completion, originality, and overall execution of the Instructable. Winners will be announced on February 9, 2012.
Standards to Address:
Select from the academic standards listed below. Create a project that demonstrates, teaches, or reinforces the concept listed. Either create an original project OR collect at least four existing projects into a guide (and be sure to explain how each project connects to the standard you chose.) Remember: create something that a teacher would want to use in the classroom. That's how I'll be judging. You don't need to be a teacher to make something useful, just keep the target audience in mind.
Demonstrate how to solve problems that involve constant speed and average speed.
Demonstrate that when forces are balanced, no acceleration occurs; thus an object continues to move at a constant speed or stays at rest (Newton's first law).
Demonstrate how to apply the law F=ma to solve one-dimensional motion problems that involve constant forces (Newton's second law).
Demonstrate that when one object exerts a force always exerts a force of equal magnitude and in the opposite direction (Newton's third law).
Demonstrate the relationship between the universal law of gravitation and the effect of gravity on an object at the surface of Earth.
Demonstrate that applying a force to an object perpendicular to the direction of its motion causes the object to change direction but not speed (e.g., Earth's gravitational force causes a satellite in a circular orbit to change direction but not speed).
Demonstrate that circular motion requires the application of a constant force directed toward the center of the circle.
Demonstrate that Newton’s laws are not exact but provide very good approximations unless an object is moving close to the speed of light or is small enough that quantum effects are important.
Demonstrate how to solve two-dimensional trajectory problems.

The specific uses for the cart are described on the last page of the instructable.
The slingshot rockets are a great lesson for illustrating trajectory. Since the launcher is held in one hand and the rocket in the other, students can experientially comprehend trajectory by adjusting the direction in which the rocket is pointing upon release. Newton's second law is also utilized during launches: launching the rocket pulling back on the rubberband and releasing is a very straightforward example of actions (pulling the band) having an equal and opposite reaction (rocket launch).
Thanks for creating this challenge!

Insider tip: The next Academic Challenge will be for Elementary Art.
http://www.instructables.com/id/Inexpensive-Rubberband-Powered-Helicopter/
The helicopter project is perfect for illustrating Newton's third law of motion. The downward force generated by the spinning propeller creates 'an equal and opposite reaction' by lifting the craft into the air until the energy is expended.
http://www.instructables.com/id/Teach-Engineering-Truss-Bridges/
All forces of the bridge must remain balanced at all times, even during changing variables, or else the entire structure will collapse.
http://www.instructables.com/id/Hydraulic-JudoBots/
This project covers many of Newton's concepts, but it is most illustrative of his second law. JudoBots attempt to flip each other, which means that the force provided by the hydraulic-powered arm must be greater than the forces keeping the opponent's robot in place. In the equation F=ma, the greater the force, the more effective the robot is in combat. Also, since F must overcome m, heavier robots are desirable.
And although my project is included in the guide, I would like to enter it separately as well: http://www.instructables.com/id/Teach-Engineering-Crash-Test-Racers/
This project is a balance of Newton's second and third laws. If F=ma then heavier cars will generate more momentum and thus a more violent impact. Newton's third law is applicable when considering the safety of the egg. A crash will direct force into the wall as well as into the car in equal measure. Thus students should strive toward creating a car that is both fast (high mass) and safe (capable of protecting an egg from the inevitable consequences of Newton's third law).
You've pretty much written the text for a guide already. Just add all of these into a single guide (kinda like mine, I even used one of yours!), and submit the link to the guide.
(Please let me know if any of those were published after January 23 so I can be sure to let them in.)

Physics might not come around for a bit, so get while the getting is good. It'll take a while to get through all the flavors of physics. (Though a thermodynamics one sounds like it might be pretty cool...)
Here's a guide of four projects with a learning objective and the relevant standard included. Just in case you want to make a guide of your own but just weren't sure what they look like.
This is a great contest!
They're there to help your creativity, not hinder it.
