RICHARDTON HIGH SCHOOL TECHNOLOGY DEPARTMENT RICHARDTON, NORTH DAKOTA
THE ELECTRIC POWERED BOAT
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 construct a watercraft vehicle.
The vehicle must travel the length of the 10 foot "river" and return.
Hull designs should be reviewed and researched before the design process begins.
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.
Blue Styrofoam 1.5" x 5.5" x 6"
1 Boat Prop
Red drinking straw
LIMITATIONS:
The capacitor on the electrical mechanics may be replaced with a AA or AAA battery..
EVALUATION:
Students will test their own watercraft vehicles.
The instructor will be the official assessment recorder.
Evaluation will be done with the "river". A 10 foot 6 inch PVC half pipe. Filled with approximately 5 gallons of water.
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 watercraft submitted.
And or
20 points = The vehicle that traveled the total distance of the "river" and returned.
19 points = The vehicle that traveled 90% of the total distance.
18 points = The vehicle that traveled 85% of the total distance.
17 points = The vehicle that traveled 80% of the total distance.
16 points = The vehicle that traveled 70% of the total 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.
