2. Do Now

What system in your body has to do with food? (circulatory system, digestive system, or respiratory system) What parts of your body are in this system?

Take 5 Minutes and write all that you know.

Goals for this lesson

to understand the path that food takes through the body

-understand how food gets broken down through the digestive system

• Module 3-1: Weight and Friction

  Mass and Weight are NOT the same! Weight depends on Mass. Weight is the downward force of gravity pulling on an object. ​Friction is a contact force that resists motion. ​It depends on the surfaces' material and the force pushing them together. The coefficient of friction ​determines how "sticky" a surface is. Higher = "Grippy" & Lower = "Slippy"

Module 3-2 and 3-3: Newton's Laws

1st: An object will not change its motion unless acted on by an unbalanced force. 2nd: The acceleration of an object is directly proportional to the applied force. 3rd: When one object exerts a force on another, the second object exerts an equal and opposite force in return

Multiple Choice

Which best describes the speed of a ball as it is thrown straight up into the air and comes back down?

• The ball goes up at a constant speed, stops, then comes down at a constant speed. The ball goes up at a constant speed, stops, then comes down at a constant speed.

• The ball goes up at a constant speed, stops, and increases speed as it comes down

• he ball goes slower and slower as it goes up, stops, and then goes faster and faster as it comes down.

• The ball goes slower and slower as it goes up, stops, and then comes down at a constant speed.The ball goes slower and slower as it goes up, stops, and then comes down at a constant speed.
