ADJECTIVES are describing words! They should be used to full express the characteristics of the materials we encounter in this unit. Remember to use all of your senses when experiencing a material.
NATURAL VERSUS MAN-MADE MATERIALS:
Man-made materials: Natural material + tools + skill
Man-made materials: Natural material + tools + skill
WHAT MAKES BRIDGES SO STRONG?:
Beam vs. Truss (The use of triangles spreads out the weight of the load) vs. Suspension
Beam vs. Truss (The use of triangles spreads out the weight of the load) vs. Suspension

FORCE: A push or pull
TYPES OF FORCE: gravity, friction, upthrust/buoyancy, air resistance, turning, shearing, magnetic, spring etc.
WORK is completed when a force is applied and energy is applied.
SIMPLE MACHINES make work easier. They either change the direction of force and/or the amount of force needed using a mechanical advantage!
TYPES OF SIMPLE MACHINES: levers, inclined planes, wheel and axle, screw, pulley, wedge
OTHER KEY WORDS: load, effort, fulcrum, distance, longer, shorter, harder, easier
