Desk Challenge Worksheet: Designing the Perfect Desk
Directions: This is the challenge information sheet you will be completing throughout unit 7. One copy of this for your group is due with your project on the last day of the unit. The project will be taken for a test grade.
Big Idea: How do we improve our learning environment?
Essential Question: What is the design for the perfect student desk?
Your CHALLENGE:
- Design what you believe to be the perfect desk. You must show all dimensions for the volume and surface area of your desk. All measurements should be done in square centimeters.
The desk must be the correct size to fit in our classroom[JAB1]( ______) with enough room for 30 of your desks.
- Your desk materials cannot cost any more than [JAB2]______
- Material Choices (you can research your own if you want something different, but it must be approved by your teacher).
Materials / Cost
Melamine – a hard plastic that can be used for the desk top. / $0.01 per square centimeter
Maple wood table top – a light-brown colored table top made of real wood. / $0.03 per square centimeter
Cherry wood grain laminate table top – a laminated table top that looks like a reddish wood. / $0.02 per square centimeter
Decorated Glass – a glass with a pattern etched in it for your desk top. You can pick the pattern you want in it. / $0.04 per square centimeter.
Steel – metal used for your desk legs. / $0.01 per cubic centimeter
