  1. 8th Grade Science Do Now Monday, March 18, 2013 Make the weekly Do Now on page ___. Draw a “photo” of yourself over spring break. Your photo must have 3 colors, a caption, and a description underneath it.

  2. 8th Grade Science Today’s Schedule Monday, March 18, 2013 Do Now BBs vs. Marbles Write a Law Video Essential Question Vocabulary How do we calculate and communicate the change in position, direction and speed for moving objects? How do unbalanced forces affect the motion of an object? How de we transform energy to make it useful? Acceleration Velocity

  3. 8th Grade Science Today we will… Monday, March 18, 2013 8.6 (B) differentiate between speed, velocity, and acceleration Objective: Students will be able to explain how mass and acceleration are related.

  4. 8th Grade Science BBs vs. Marbles Monday, March 18, 2013 Move the containers with BBs and marbles from side to side and record 5 observations in your notebook on page __. Then, copy and answer the following questions: What were the similarities in the motion of the BBs and the marbles? What were the differences in motion between the BBs and the marbles? Make a hypothesis about why there were differences in their motion.

  5. 8th Grade Science Write a Law Monday, March 18, 2013 If you were going to write a rule about how objects moved based on their mass, what would you write? As a table, write a law based upon your observations with the BBs and marbles.

  6. 8th Grade Science Video Monday, March 18, 2013 Three Laws of Motion

  7. 8th Grade Science After Video Monday, March 18, 2013 After watching the video, revise your law.

  8. 8th Grade Science After Video Monday, March 18, 2013 Newton’s 2nd Law of Motion Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object).

  9. 8th Grade Science Do Now Tuesday, March 19, 2013 Jack throws a tennis ball as hard as he can across a field. Then, he throws a bowling ball across a field as fast as he can. Describe the difference between the force, acceleration, and mass of the objects.

  10. 8th Grade Science Today’s Schedule Tuesday, March 19, 2013 Do Now Video Acceleration Essential Question Vocabulary How do we calculate and communicate the change in position, direction and speed for moving objects? How do unbalanced forces affect the motion of an object? How de we transform energy to make it useful? Acceleration Velocity

  11. 8th Grade Science Today we will… Tuesday, March 19, 2013 8.6 (B) differentiate between speed, velocity, and acceleration Objective: Students will be able to define acceleration and describe how a greater force causes greater acceleration, and less mass causes greater acceleration.

  12. 8th Grade Science Video Tuesday, March 19, 2013 Roller coaster video As you watch, record 3 examples of acceleration and 3 examples of deceleration.

  13. 8th Grade Science Acceleration Tuesday, March 19, 2013 • If an object speeds up, slows down, or changes direction, the objects is accelerating. Acceleration occurs because a force acts upon an object, causing the object to change its speed or direction. Recall that a force is a push or pull. Acceleration can also be described as a change in velocity. Any object increasing or decreasing its speed or changing directions is accelerating. • On page ___, • List at least 3 vocabulary words • Copy the most important sentence from the reading • Write the definition of “Acceleration” in your own words

  14. 8th Grade Science Acceleration Tuesday, March 19, 2013 Complete RM 9 and RM 11.

  15. 8th Grade Science Do Now Wednesday & Thursday, March 20 & 21, 2013 On page 76… Draw a graph with an x- and y-axis. Labeled the y-axis “speed” Label the x-axis labeled “time”. Draw a line that would show an object staying at a constant speed.

  16. 8th Grade Science Today’s Schedule Wednesday & Thursday, March 20 & 21, 2013 Do Now Finish RM 9 and 11 Gum Lab Gallery Walk White Board Review Essential Question Vocabulary How do we calculate and communicate the change in position, direction and speed for moving objects?
