Students will learn about the six simple
machines, play some online games, write problems
calculating mechanical advantage and design and
construct a working model of a Rube Goldberg
machine using at least three of the six simple
machines. Introduction The goal of this webquest
is to allow you to extend your knowledge of
simple machines beyond our time in the classroom.
You will do this by learning about a man named
Rube Goldberg who drew complicated cartoons to
accomplish a simple task. You will work both
individually and as a group with the students at
your science table. Collaboration during class is
an extremely important part of this project.
3
Task Your task is to design and build a
three-dimensional Rube Goldberg Machine that uses
at least 3 different types of simple machines to
accomplish one task. You may use as many of
each type of machine as needed. (For example, you
may use 3 levers, 2 pulleys and 1 inclined
plane.)
4
Process For this project there will be individual
assignments and a group assignment. Make sure you
complete your individual assignments so that you
are ready and able to help your partners complete
the group assignment. TASK 1 Gaining Information
- individual Visit the following websites to gain
information about the project. Simple Machines
information http//www.edheads.org Click on
simple machines and START. Go to the HOUSE and
visit all the rooms. Print out your score for at
least one room.

TASK 2 - Preliminary Designs - individual Design
a Rube Goldberg Machine that will fit on the top
of your science table. You must use 3 different
types of simple machines but you can use as many
of them as you want. Bring ideas and sketches to
class to share with your partners. You will have
several times during the next couple of weeks to
do this.
9
TASK 3 - Design Collaboration - group Bring ideas
and sketches to class to discuss with your group.
You will have 15 minutes at the beginning of each
class to work together on the final design.
10
TASK 4 - Final Design - group Complete final
design diagram. Determine what materials are
needed to complete the machine. Make a materials
list. Determine which of the materials each
member can bring from home. Use simple materials
found at home - be creative.
11
TASK 5 - Mechanical Advantage Problems -
individual Make up three word problems for each
of the following simple machines lever, pulley
and inclined plane 2. Type/write them neatly and
solve each one showing your work.
12
TASK 6 - Building the Machine - group Build the
machine in class with materials brought from
home. Must follow design diagram. Be of sound
construction It must work by the end of the
class!

Collaboration during planning All members always provided useful ideas while participating in planning. Most members provided useful ideas while participating in planning. Some members provided useful ideas while participating in planning. Members rarely provided useful ideas while planning. That is - one member of the group did all the work.
Collaboration during building All members worked well and put forth great effort. Group worked well and put forth good effort. Some of the group worked well and put forth some effort. Group did not work well and did not put forth much effort.
