Simple / Compound Machines Information

Curriculum Link… Science + Applied Design, Skills, and Technology

Compound Machine Assignment
Due:  Thursday, June 15, 2023

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 have 
been 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.
 
       GROUPS OF 2 IS BEST  - STUDENTS MAY ALSO WORK ALONE.


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. You need to be able to carry your materials to class. 

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 and teacher.  Talk over your ideas.  See if you all agree that your idea is possible.  Once you have come up with your idea, please decide on materials to use so that your teacher 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?
Bring items to school. 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. This is mostly an at-school project, but it is expected that parents will be involved.


How the assignment will be assessed:

         Compound Machine: 
·        Two or one simple machines = Emerging
·        Three or four simple machines = Developing
·        Five or six simple machines = Proficient
·        Adding something(s) beyond expectations that involves high levels of complexity = Extending

Due Date: Thursday, June 15… In the AFTERNOON we will share our designs with our classmates. 

Note: This is the only day students will be able to present their compound machines. Late entries will not be assessed; whatever you have created, regardless if it is a working machine or not, will be your machine.
