Welcome to the MathScience Innovation Center “LEGO Machines and Energy” with Mrs. Kappus
SIMPLE MACHINES • Compound Machine is a machine made of two or more simple machines.
SIMPLE MACHINES • Work = Force X Distance
SIMPLE MACHINES • Energy • is the ability to do work.
LAPTOP COMPUTER • The Laptop Computer runs software: • ROBOLAB
LAPTOP COMPUTER • The mouse is used to move • __________
LAPTOP COMPUTER • The mouse is used to move • The CURSOR
LAPTOP COMPUTER A Picture of an object on a computer is _____ an ICON
REMOTE CONTROL DEVICE • The Gray Cube is a _____
REMOTE CONTROL DEVICE • The Gray Cube is a MOTOR. • The motor uses what type of energy to move? ELECTRICITY
ASSEMBLE REMOTE CONTROL CAR • Mount Motor • Gears
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.
ASSEMBLE REMOTE CONTROL CAR • Mount Motor • Gears • Mount RCX Brick • Test Car with Program #1
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?
Experiment • Begin with a question. • Will the car travel farther on the track or on the carpet surface?
EXPERIMENT • Hypothesis
EXPERIMENT • Hypothesis-An educated guess or a prediction
EXPERIMENT • Hypothesis • The car will travel farther on the ________.
EXPERIMENT • Hypothesis • Constant
EXPERIMENT • Constant-parts of the experiment that stay the same
EXPERIMENT • Hypothesis • Constant • Variable
EXPERIMENT • Variable-the factors in an experiment that change.
