Introduction



Help!


Moving Major Mountains
, a new and upcoming moving company is in need of
your help.


The owner of a very valuable Egyptian artifact is moving into a new
apartment
within his building.


He owns a priceless Ancient Egyptian water clock.


However, due to the delicate nature of the water clock, no human hands may touch
the artifact.


The owner is also extremely concerned about how this item is to be
moved and has detail
ed specific limitations to the moving company as to how the
water clock is to be moved.


Some of his stipulations include no human
hands

touching

the clock.

However, gloved hands may briefly move the object to a
moving device or transportation method.


Al
so,

the elevator in the building has
been acting funny lately with the sprinkler system going off unwarranted so the
stairwell must be used instead.

The moving company is eager to please their
customer and has agreed to design an invention that will do th
e job.


However, this
is a busy time for

Moving Major Mountains
, and they are seeking to hire you to
design a machine to do the job.




















































































Task













1. Your task is to design an invention that will move the ancient
water clock from the 25
th

to the 26
th
floor of

the Nelson
Building.


The rules of the owner must be upheld in the design of
the machine
which he has

provided

in writing.



The elevator cannot be used to move the water clock.

The
stairwell must be used.

It consists of two sets of 10 steps.




Human hands may not carry the water clock due to the
delicate nature of the clock.

Gloved hands may

move the
clock to a platform for transport, but human handling of the
artifact should be minimal.



Also, since the owner is a fan of the famous

Rube
Goldberg

projects, he requires that this
invention must
consist of at least two simple machines (compound
machine).


2.

Once a design for your machine is planned, a replica of it
needs to be created.


3.

This

machine must be presented to the president of

Moving
Major Mountains

for final selecti
on in the form of a commercial
advertisement.








Process


You are to work in learning groups.


You will work as a group to
accomplish the tasks at hand.



1.

Gather background information







Working with your group, you must first research
and define

six
simple machines.


You each will record the name and definition of
each of the six simple machines in your science journal.


Using the information, you must make a poster that provides a
description of the

lever, screw, wheel and axle, pulle
y, inclined
plane, and wedge
.


Your poster should also contain pictures and/or drawings of

"real
world" examples of each of these simple machines.


The
resources listed and linked below in the Resources Section will
provide the information needed for
you

to create your poster.

Present poster to teacher when completed prior to going on to
step #2.

2.


Design and create a compound machine







You and your group must develop a plan, drawing, or sketch of a
compound machine that you propose to build.

Th
is is required so
that you can combine two or more of these machines to develop
a compound machine of your own.

Once you have a plan, it must
be informally presented to the teacher for approval prior to
building it.


Classroom supplies such as "legos", "
tinker toys", screws,
marbles, string, etc. will be made available for use.


If additional
materials are needed, they must be requested in writing.

Once you have your materials and approval, you may build your
machine.

When completed go on to step #3.

**R
eminder, you are working as a group, so make sure you know your group role
and the responsibilities that go along with it.**


3.

Plan and deliver your presentation






Your

job is to

convince the president of Moving Major Mountains
that your machine will move his water clock.




Name your machine.



Create a slogan for your machine.



Create an advertisement (commercial) that describes your
machine and demonstrates how it will wor
k.




You are required to

create a script for your commercial.



Within the commercial, be sure to identify the types and
function of each simple machine component in your design.




All group members need to

have a speaking part.



Your commercial should last

1
-
2 minutes.

You must have your script approved by your teacher before you begin rehearsing
for your presentation.




















































































































































Resources





The Inventor's Tool Box

-

Machines are explained, described and
examples are presented.

Has an excellent link to "Gadget
Anatomy" to identify simple machines present in a compound
machine.


Simple Machine Learning Site

-

Contains an overview of the six
simple machines and examples of each.


MIKIDS Simple Machine Site

-

Site has descripti
ons of simple
machines and ideas/instructions on how to make these machines
from common items.


Edheads Simple Machine Site

-

Site contains interactive play to
identify simple m
achines in use.


Franklin Institutes's Simple Machine Site

-

Contains a good
overview of simple machines and examples of each.


Don’t forget to look for your own resources for in
spiration!

























































































Evaluation and Conclusion




Evaluation



You will be graded on your
informational poster,

compound
machine, and commercial.


Please examine the attached rubric
for the specifics as to

how you will be assessed.

Conclusion






Now that you have completed building your

compound
machine, you know that a machine makes work easier.

Without
machines work would be harder and require more effort on the
part of humans.

Be on the look out for all the machines that you
use througho
ut the course of the day.

Simple and compound
machines are incorporated in so many of our daily activities that
we often don't appreciate how many we put to use in one day.

So next time you ride your bike to the neighborhood park or
sharpen your pencil a
t school, you can thank those simple
machines for making your task a bit easier!
