WARM-UP: NEW Behavior Log is filled out for 10/17/16 Copied Objective, HW into assignment list WARM-UP: One example of a simple machine is a screw. Name two other kinds of simple machines or examples of them.

Mantra - Your Turn! Today is a great day for science because: Science is power. We are powerful because: We always make a difference.

Goals * State the Objective(s)/Standard (s)- RI 7.3; W2; Sci 2c * State the Purpose (Big Idea) - SWBAT explain how movement is related to energy and work, and apply problem solving skills to real life situations as told in a pick-your-path-story. SWBAT Compare/Contrast the appearance, role, and uses of 6 kinds of simple machines

Pulley Use the whiteboards in groups of 4 Draw it!

Pulley – Answer! Update your charts!

Pulley Use the whiteboards in groups of 4 2. Say what it does!

Pulley – Answer! Update your charts! A pulley is a wheel on an axle or shaft that is designed to support movement and change of direction of a cable or belt along its circumference. Pulleys are used in a variety of ways to lift loads, apply forces, and to transmit power.

Wheel & Axle – Answer! Update your charts!

Wheel & Axle Use the whiteboards in groups of 4 2. Say what it does!

Wheel & Axle – Answer! Update your charts! The wheel and axle is generally considered to be a wheel attached to an axle so that these two parts rotate together in which a force is transferred from one to the other. The mechanical advantage of a wheel and axle is the ratio of the radius of the wheel to the radius of the axle

Incline Plane– Answer! Update your charts!

Incline Plane Use the whiteboards in groups of 4 2. Say what it does!

Incline Plane– Answer! Update your charts! An inclined plane, also known as a ramp, is a flat supporting surface tilted at an angle, with one end higher than the other, used as an aid for raising or lowering a load.
