1. Welcome to Lego Energy Mathematics & Science Center

2. Simple Machines

3. Compound Machine Made of 2 or more simple machines Also known as a complex machine

4. Work Force is applied over a distance Force is a “push” or “pull” Use math to calculate Work = Force x Distance

5. Energy Ability to do work Different kinds of energy Electricity Mechanical Light Sound etc.

6. Computer Workstation

7. Computer runs the ROBOLAB software

8. Computer Workstation Mouse is used to move the cursor

9. Computer Workstation Monitor displays icons Icons are pictures of an object on the screen

10. Remote Control Car Gray cube is a motor Motor uses electrical energy to move

11. Remote Control Car Yellow BRICK is an RCX Brick Contains a computer Uses electrical energy to run Controls the car when we finish programming it

12. Assembly of Remote Control Car Gears Mount Motor Mount RCX Brick

13. Electricity Conductor – carries an electric current Insulator – does not carry an electric current

14. Types of Energy Potential – energy of position Kinetic – energy of movement

15. Recap Work = Force X Distance Energy is capacity to do work RCX Brick will release the same amount of energy each time

16. Will the car always go the same distance?

17. Experiment

18. Parts of an Experiment Manipulated variable – What YOU change Responding variable – What changes on own Constants – things that stay the same

19. Hypothesis Educated guess If (change manipulative variable) then (change responding variable) If car travels on ___ then the car will _____

20. Experimental Data
