Simple & Compound Machines

Homework Due @ Start of Class

Simple and Compound Machine Practice with

K*Nex

We have reviewed a lot about simple machines... Now it is time to make our own!

You have the rest of class to design a compound machine that combines at least 3 simple machines. It must serve a specific purpose (in basket), and you must submit a mini-plan (in notebook) before moving into the tool lab for construction.

Steps:

1. Pre-Plan- read the "Snoots" problem sheet in the eng 2 basket.

You will need to combine 3 simple machines to create a K*Nex compound machine that serves a real life purpose. You will need to use the internet.

Some simple machine ideas HERE.

In your notebooks, sketch out your idea with all simple machines labelled.

Then, create a FULL LIST of all the pieces you will need to make this machine.

(ie. 20 red pieces, 4 yellow pieces, 2 large green gear wheels, etc.)

Beneath your sketch and list, write a short explaination of the function of the machine in real world terms. How is it going to solve the problem?

2. Bring your sheet over to the teacher for a sign off.

You will need to be able to explain all the moving parts of your design, as well as its purpose.

You will recieve a gallon-sized bag to collect your pieces.

3. Collect your K*Nex pieces and begin construction.

You will have through the end of class (and possibly 3/4 of next class) to complete your design.

When it is time for clean up, return any loose pieces to your bag with your mini-plan sheet.

Take your bag and K*Nex machine to the tan student cabinet by the machine counter for storage.

4. Present your plan to the class.
