RICHARDTON HIGH SCHOOL TECHNOLOGY DEPARTMENT RICHARDTON, NORTH DAKOTA
THE ALL TERRAIN ELECTRIC POWERED VEHICLE
CONTEXT:
Since the beginning, people have marveled at natures ability to adapt to the environment. When Leonardo de Vinci worked on an idea, he typically would spend time observing nature. The interrelations and the causalities behind them. When Wilbur and Orville Wright began researching and developing the concept of human flight, they of course studied the flight of birds. It is important to study nature and how many forms of transportation are combine as a means of ensuing survival.
Think like a duck for a minute. Where did you picture it? Was it in flight? Was it in the water? Or was it waddling along on the ground? This activity will give you the opportunity to combine two or more, if you are really creative, three forms of transportation in to one useful unit, perhaps like a duck.
OBJECTIVE:
To learn that the scientific method is not a linear process.
To learn the difference between potential and kinetic energy. To learn to use different forces of prime movers; mechanical, fluid, electrical, heat, chemical.
To learn the principles of forces like compression, torsion, strain, and shear.
Learn the principles of friction.
Learn the basics of circuitry and how to solder.
To work independently or cooperatively. To learn to brainstorm (lens smashing) and develop problem solving skills. Make decisions using trial and error. Work within a given amount of time. Work with only materials given. Deal with competition with your peers.
PROBLEM:
Given the materials from the KELVIN Hovercraft kit along with additional materials, construct a vehicle powered by an electric motor that will traverse a variety of surfaces, this may include water.
GIVEN:
Hovercraft kit repurposed parts
Access to other resource materials
Soldering iron
Solder, flux etc.
Hot glue melt
Access to limited power tools and equipment.
LIMITATIONS:
The vehicle must be self contained.
The vehicle must be built to scale and in proportion. At the discretion of the instructor.
The capacitor on the electrical mechanics may be replaced with a AA or AAA battery.
aReduction gears and assemblies may be designed. (gearbox from KELVIN).
Student may bring their own resource materials and parts.
No explosives or other dangerous items allowed.
Power tool use will be monitored at the discretion of the instructor.
EVALUATION:
Students will test their own vehicles.
The instructor will be the official assessment recorder.
Vehicles will be tested on a all terrain surface. Developed by the class.
Depending on weather conditions, this course could be designed outdoors.
The designed course must be designed at the discretion of the instructor.
Points would be given on appearance, workmanship, quality, and performance.
20 points = 4 out of the 4 disciplines met.
18 points = 3 out of the 4 disciplines met.
16 points = 2 out of the 4 disciplines met.
14 points = 1 out of the 4 disciplines met.
0 points = no hovercraft submitted.
And or
20 points = The vehicle that traveled the longest distance.
19 points = The vehicle that traveled 90% of the longest distance.
18 points = The vehicle that traveled 85% of the longest distance.
17 points = The vehicle that traveled 80% of the longest distance.
16 points = The vehicle that traveled 70% of the longest distance.
And or
20 points = The vehicle that traveled the fastest over the entire distance.
19 points = The vehicle that traveled 90% fastest over the entire distance.
18 points = The vehicle that traveled 85% fastest over the entire distance.
17 points = The vehicle that traveled 80% fastest over the entire distance.
16 points = The vehicle that traveled 70% fastest over the entire distance.
