READING ROADMAP1. The “location” column provides the page numbers

where you should focus your reading.2. The “speed” column directs you as to how much

time you should spend reading the information on those pages.

3. The “mission” column directs you as to what you should be thinking about as you read the information on those pages.

4. You should only answer a question in the “Mission” column if you are directed to write in the “Speed” column.

Objective: To identify and describe simple machines in order to analyze how

simple machines are used in a roller coaster.Core Question: What is a machine?

Drill: 1. Take out yesterday’s lab. 2. You have 10 minutes to complete the

reading roadmap. If you finish, review the reading to sharpen your understanding of the concepts. 3. Write down any questions you still have about any concepts that are confusing.

What is a machine?A device that makes work easier or more effective

List three ways machines might make work easier.

*multiply the force*multiply the distance*change the direction

Simple Machines

Describe two ways a lever helps you accomplish work.

1. Levers change the direction of the force.

2. Levers increase the effect of your input force.
