  1. Welcome to the MathScience Innovation Center “LEGO Machines and Energy” with Mrs. Kappus

  2. SIMPLE MACHINES

  3. SIMPLE MACHINES • Compound Machine is a machine made of two or more simple machines.

  4. Remote Controlled MACHINES

  5. SIMPLE MACHINES • Work = Force X Distance

  6. SIMPLE MACHINES • Energy • is the ability to do work.

  7. LAPTOP COMPUTER • The Laptop Computer runs software: • ROBOLAB

  8. LAPTOP COMPUTER • The mouse is used to move • __________

  9. LAPTOP COMPUTER • The mouse is used to move • The CURSOR

  10. LAPTOP COMPUTER A Picture of an object on a computer is _____ an ICON

  11. REMOTE CONTROL DEVICE • The Gray Cube is a _____

  12. REMOTE CONTROL DEVICE • The Gray Cube is a MOTOR. • The motor uses what type of energy to move? ELECTRICITY

  13. ASSEMBLE REMOTE CONTROL CAR • Mount Motor • Gears

  14. REMOTE CONTROL DEVICE • The Yellow BRICK is an RCX Brick which contains a computer. • The Brick uses what type of energy to run? • ELECTRICITY • The RCX Bricks will control the Car when we are done.

  15. ASSEMBLE REMOTE CONTROL CAR • Mount Motor • Gears • Mount RCX Brick • Test Car with Program #1

  16. RECAP • WORK = Force x Distance • ENERGY is the ability to do work • Energy can be potential or kinetic • The Brick will release the same energy every time • doing the same work every time • Will the car always go the same distance?

  17. Experiment • Begin with a question. • Will the car travel farther on the track or on the carpet surface?

  18. EXPERIMENT • Hypothesis

  19. EXPERIMENT • Hypothesis-An educated guess or a prediction

  20. EXPERIMENT • Hypothesis • The car will travel farther on the ________.

  21. EXPERIMENT • Hypothesis • Constant

  22. EXPERIMENT • Constant-parts of the experiment that stay the same

  23. EXPERIMENT • Hypothesis • Constant • Variable

  24. EXPERIMENT • Variable-the factors in an experiment that change.
