Compound Machine Assignment
Due:
Friday, June 21, 2019
What is a Compound
Machine?
A compound machine is a machine made up of more than one
simple machine. Types of simple machines
include the lever, wedge, pulley, ramp (inclined plane), screw, and wheel and
axle. We will be learning about these in class.
What are the goals?
1.
To demonstrate a clear understanding of how simple
machines work by creating a compound machine.
2. Prototype:
a)Outline a general plan, identifying tools and materials
b) Construct a first
version of the product, making
changes to tools,
materials, and procedures as needed
c) Record changes of
prototyping.
3.
Provide a written paragraph that explains how their
compound machine works.
4.
Build a compound machine that works and performs a
task.
5.
Be able to explain verbally how your machine
accomplishes its task. Please use the
appropriate vocabulary: force, motion,
load, fulcrum, distance and so forth.
We are trying to use “science” words when describing our compound
machines.
6.
Create a sign that names your machine & parts.
Ensure that it is legible.

How to build your
compound machine:
Use your knowledge of simple machines, your creativity, and
your ingenuity. Look for other examples
on YouTube. If you need advice, ask
other students, your teacher or your parent/guardian.
Is anything
off-limits?
Your machine needs to be safe.
What do I do first?
Think of a problem or an idea where you think a compound
machine would be useful. Do some brainstorming. Make a sketch of some simple machines you may
include. If your first idea does not
work, try again. Inventors have lots of
ideas and often they encounter many setbacks before they are successful.
NOTE: There is no failure. Instead of thinking that you failed, think
about what you may do differently. It is
often the mistakes we make that help us move forward.
What do I do next?
Show your sketch and plan to your parents. Talk over your ideas. See if you all agree that your idea is
possible. Once you have come up with
your idea, please show your teacher so that they can approve it.
After my compound
machine plan has been approved by my parents and/or Mr. Bartraw, what do I do?
Start gathering the material you need to make your compound
machine. You can look pretty much anywhere.
You might use cereal boxes, parts of a broken-down toy, recycling, scrap
material, tool boxes, “junk” from your closet, or even something under your
bed! Please remember to ask your parents
before you turn something from home into your compound machine.
Once I have my
supplies, what do I do?
Start putting your compound machine together. Patience is extremely important at this
point. Make time to work on this
project.
How can my parents
help?
You can discuss your ideas with your parents. Your parents
may need to take you places if you need certain materials. Since this is mostly
an at-home project, it is expected that parents will be involved.
Often, the number one comment made by students
is this: “I enjoyed spending one on one
time with my parent(s) while building this!”
How the assignment will be assessed:
Compound
Machine:
·
Two or fewer
simple machines = Emerging
·
Three simple
machines = Developing
·
Four or more
simple machines = Proficient
·
Adding
something(s) beyond expectations that involves high levels of complexity = Extending

Due Date: Friday, June 21… In the morning we will
share our designs with our classmates. All parents are welcome to attend.
Note: This is the only day students will be able to
present their compound machines. Late entries will not be assessed; bring in
what you have created, regardless if it is a working machine or not.
