In class, we have discussed motion, forces and simple machines.
Today, your mission will be to complete the following tasks:
TASK 1 RUBE GOLDBERG
First, let's start with Rube Goldberg. Using your Science Journals, you and your partner will answer
the following questions:
* Who was Rube Goldberg? What did he do for a living?
* Describe 2 or 3 of his drawings?
* Draw your own Rube Goldberg drawing including at least three steps.
You may choose one of the suggestions below, or create your own!!
1. Water a plant
2. Turn on a light
3. Place a ball into a basket or shoot a basketball

TASK 2 ROLLER COASTER
How does a roller coaster work?
What you may not realize as you're cruising down the track at 60 miles an hour is that the coaster
has no engine. The car is pulled to the top of the first hill at the beginning of the ride, but after that
the coaster must complete the ride on its own. You aren't being propelled around the track by a
motor or pulled by a hitch. The conversion of potential energy to kinetic energy is what drives the
roller coaster, and all of the kinetic energy you need for the ride is present once the coaster
descends the first hill... (learner.org)
1. Test your knowledge of potential and kinetic energy! See if you can make this roller coaster work!

TASK 3 SIMPLE MACHINES
We use machines everyday help to make our work easier. There are six different types of machines.
The links below will help you identify the different types of simple machines. You will first complete
a worksheet identifying simple machines. Then try to make a simple machine work in part two.
Part One:
Identify and label the simple and compound machines on your handout.
Six Simple Machines
Part Two:
Once you have completed part one, click on the link below and see if you can make the simple
machines work.
