Transcript of Pine Car Derby

Your #1 Goal:
Win!
The fastest car down the track wins.
Problem:
Your block of wood on wheels needs to travel down the track to the finish line as fast as possible.
Step 1: Researching
Some people say that "experience is the best teacher," but that is wrong.

"Other people's experience is the best teacher."
It is quicker, and dead-ends are found much sooner. Your time is valuable so seeing what others have done and improving on their thinking is a much more efficient model.
Models:
The Great Gravity Race!
Blueprints:
All engineers must get their plans approved before they begin construction on final projects!
Using graph paper, accurately diagram your prototype pinewood car.
come up with a cool project name for a title
name and date
use a ruler
label all parts
consider drawing from more than one angle (top, side)
use a scale
Take completed plans and meet with the Deputy Race Official for approval.
Be prepared to explain your plans.
What is allowing your car to travel quickly?
What will be the tricky parts of construction?
Plans are rarely perfect the first time, so expect feedback and corrections may be necessary.
Academic Levels:
4.) Blueprint is neat, tidy, accurate, labeled, and
to

scale
.
3.) Blueprint is neat, tidy, mostly accurate and to scale.
2.) Blueprint may be messy in places or contain some inaccuracies.
1.) Blueprint is messy and contains inaccuracies.

Quick Start: https://drive.google.com/file/d/0B1t3QxSmPwgHSW1XSnJaUmYwN3M/view?usp=sharing

Knowledge Levels:
4.) Student can independently explain their strategies for a fast car using scientific language.
3.)Student can independently explain their strategies for a fast car using some scientific language.
2.)Student needs prompting to explain their strategy(ies) for their car.
1.) Student cannot explain how their construction is related to scientific principles.
Construction:
At school during extra work periods.
Must follow blueprints exactly!
Must meet project constraints.
All projects should have a refined look to them.

Launch!
Date: May, TBA
The Overall STEM Learning Plan
Ask:
What is the problem?

What are the parameters?

What are the constraints?
Constraints:
Wheels may not be modified
No motors
No wheel bearings, washers, or bushings
No starting devices (only gravity)
The car shall not ride on any kind of spring
Width shall not exceed 2-1/4 inches.
Length shall not exceed 7 inches.
Weight shall not exceed 142 grams
Parameters
Car plans must be completed and approved before construction begins.
The car may be not constructed of any material except the
pinewood car
kit, decorations and weights.
The car must be completed at school.
The finished car must have no loose parts.
Testing:
Prototype your ideas
draw rough ideas
Test them on a small scale
build quick mini-models
Degrees of Difficulty:
Beginning: Needs assistance to complete project.
Approaching:
Needs some assistance to complete project.
REFLECT & REDESIGN:
Complete final reflections package:
