UNIT C PROJECT:
Application of Fluid Systems
Instruction:
Using what you have learned about fluids, pressure,
and Pascal’s Law, design and build a hydraulics or pneumatics system that
represents ONE of the machines listed below.
In a small group of 2 or 3, you must construct a
working model along with an appropriate three-dimensional setting. You will
also submit a half-page written report and a labeled diagram on the fluid
system you built.
The
final product
-
must be 3-D and
sits on top of a platform (for easy carrying and displaying)
-
must be colourful
AND include scaled down models of relevant objects and characters
-
CANNOT exceed a
base area of 30 cm x 30 cm
List of machines:
Option #1:
A hair salon chair that is
able to adjust its height.
Option #2:
A drawbridge that can be lifted to allow boats to pass
below or lowered to allow vehicles to drive through.
Option #3:
A dump truck that can ‘dump’
the contents out of its container. This truck must also be mobile.
Option #4:
A Jack-In-The-Box that has a
toy figure pop out (or extend out of the box).
Option #5:
An elevator that can ascend and descend in a building
that has at least 4 levels. The elevator must be able to stop at any floor.
Option #6:
A car hoist that allows cars to be parked at a raised
level. Must include a parking lot.
Project Due Date:
Class 81 à
Wednesday, June 11th
Class 82
and 87 à Thursday, June 12th
Some suggestions of
materials:
- Play-Doh or
plasticene
- syringes of different sizes (or similar materials)
- tubes of different lengths
- sturdy cardboards
- construction paper
- glue (or glue gun)
- popsicle sticks
- toys (i.e. toy cars, people, LEGO pieces…etc.)
- recycled bottles/cans/paper towel rolls/plastic cups
- paint
Assessment:
Criterion D: Scientific Inquiry
Level
|
Descriptor
|
Evidence
|
1 -2
|
The student attempts to state a focused problem or
research question. The method suggested is incomplete.
|
*Machine functions but not with
ease
*Setting is made with some
attention to details
*Includes few objects or
characters to enhance the scenario that help to communicate what the machine
does
*Pieces may not be proportional
to each other
*Written report includes basic
concepts on how the fluid system works
|
3 – 4
|
The student states a focused problem or research
question and makes a hypothesis but
does not explain it using
scientific reasoning.
The student selects appropriate materials and equipment
and writes a mostly complete method,
mentioning some of the variables involved
and how to manipulate them.
|
*Machine functions relatively
well
*Setting is well designed and
made
*Includes some objects and/or
characters to enhance the scenario that help to communicate what the machine
does
*Pieces are generally
proportional to each other
*Written report includes how
the fluid system works; includes evaluation of the mode

and how to manipulate them.
|
*Machine functions perfectly
and is very easy to operate
*Setting is well designed and
creative; well made (with attention to details)
*Includes a variety of objects
and characters to enhance the scenario that help to communicate what the
machine does
*All pieces are proportional
*Written report is
comprehensive (referring to many relevant key concepts); includes evaluation
of the model and provides realistic suggestions for improvement
