Welcome to Gateway to Technology - Science of Technology - Periods 3 and 5

Tech Plan for Week of April 18 - April 22 (Week 5)

This week we will begin a new 2 week project build called Dragster Design and Fabrication. We will design and build an aerodynamically efficient model vehicle intended to be shot down a 24 foot dual lane dragstrip using compressed air. The Air Dragster Activity is intended to be an easy, engaging, and fun activity (after what can be a difficult and chaotic Rube Golberg Device project). Each student will design and build their own dragster and will compete individually and in teams on our 2-day double elimination RACE DAY. Mr. Wheeler has been known to provide some fabulous prizes for the top 3 finishers in each class, as well as snacks and refreshments for all participants. There will be a very short briefing lesson at the beginning of each class, followed by a 30-40 minute block of time for groups to plan and construct their dragsters.

Don't be a yoke! Build a cool car, go for the checkered flag, and have some REAL fun!

Be Fast and Furious as you Feel the Need...the Need for SPEED !

Be sure to check the Day XX - Applied Physics pages for daily hints and tips!

NO STUDENTS - Assessment Day
What is the main idea:
OBJECTIVE
Students will learn to utilize the design process to produce a concept drawing of an aerodynamically efficient compressed air dragster.
Students learn to utilize measurement to determine machine markings on basic pinewood block of vehicle body and translate to CAD drawing.
Students learn how to identify drill bit types and sizes, and to safely utilize drill presses to bore the holes in a variety of materials such as wood, metals, and stone.
Students learn to identify and safely utilize scroll and band saws to cut straight and curved lines in wood of various thicknesses.

What students will learn:
ACTIVITY
Students will access the wikispace in small groups/teams and be familiarized with the project specifications and evaluation rubric.
Students measure and mark the preset machining points for the front bumper, axle shafts, and rear air insert on their default pinewood block and in the AutoDesk CAD program.
Students will use the drill presses to bore holes for their axle shafts and rear air insert. Students should work on the CAD drawing while waiting for machine time.
Students will use the scroll and band saws to cut curved or straight lines in their pinewood blocks (being careful NOT to violate the predrilled holes)

What students will do:
RESOURCES
WMS-GTT-SOT, copy of planning document, and one sheet of graph paper.
WMS-GTT-SOT, copy of planning document, numbered zip lock baggie, pinewood block, pencils, and rulers.
WMS-GTT-SOT, copy of planning document, 2 small drill presses set up with axle shaft diameter bit, and 1 large DP with air insert bit (variable depth)
WMS-GTT-SOT, copy of planning document, 2 operating scroll saws, and 2 operating band saws preset to the proper speed and safety gourd positions.

What students will need:
ASSESSMENT
Students will [[Week 5#|submit]] for teacher inspection a thumbmail or orthographic sketch of their preliminary vehicle design with appropriate dimensions by the end of class.
Students will [[Week 5#|submit]] for teacher inspection an appropriately marked pinewood block in their numbered ziplock baggie.
Students will [[Week 5#|submit]] for teacher inspection a drilled pinewood block in their numbered ziplock baggie.
Students will [[Week 5#|submit]] for teacher inspection a sawn pinewood block AND a printed copy of their isometric dragster from their U drive in a numbered ziplock baggie.

How students will show they know:
