  1. Welcome toLEGO EnergyMathematics & Science Center

  2. Simple Machines

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

  4. Work

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

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

  7. Computer Workstation

  8. Computer Workstation • Computer runs the ROBOLAB software

  9. Computer Workstation Computer Workstation • Mouse is used to move the cursor • Mouse is used to move the cursor

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

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

  12. 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

  13. Assembly of Remote Control Car

  14. Assembly of Remote Control Car • Gears

  15. Assembly of Remote Control Car • Gears • Mount Motor

  16. Assembly of Remote Control Car • Gears • Mount Motor • Mount RCX Brick • Gears • Mount Motor • Mount RCX Brick

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

  18. Types of Energy • Potential – • energy of position • Kinetic – • energy of movement • Potential – • energy of position • Kinetic – • energy of movement

  19. Recap • Work = Force x Distance

  20. Recap • Work = Force x Distance • Energy is capacity to do work

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

  22. Will the car always go the same distance?

  23. Experiment

  24. Parts of an Experiment Manipulated variable – What YOU change

  25. Parts of an Experiment Manipulated variable – What YOU change Responding variable – What changes on own

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

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

  28. Experimental Data
