Lesson Question:

What happens when objects collide? How can we design a crash protection device to absorb enough energy during a car crash to save lives?

Learning Tasks:

  1. Do Now– Get out your signed field trip permission form. How will the vehicles react in the following situation? Write your name and your answer on the piece of paper. Two cars of equal mass and moving at the same speed collide head-to-head.
  2. Reading Comprehension– “Air Pressure” ReadWorks article- In preparation for our field trip to the New England Air Museum, we’re going to learn a little about flight. To understand how flight works, we have to take a look again at air, something that we investigated when we studied about matter. And when looking at air, and more specifically air pressure, we are also taking a look at collisions. So keep in mind what we’ve been learning about speed, velocity, acceleration, and momentum as we read about the collisions of air particles.

Core Ideas:

  • For any pair of interacting objects, the force exerted by the first object on the second object is equal in strength to the force that the second object exerts on the first, but in the opposite direction (Newton’s third law).
  • The motion of an object is determined by the sum of the forces acting on it; if the total force on the object is not zero, its motion will change. The greater the mass of the object, the greater the force needed to achieve the same change in motion. For any given object, a larger force causes a larger change in motion.
  • All positions of objects and the directions of forces and motions must be described in an arbitrarily chosen reference frame and arbitrarily chosen units of size. In order to share information with other people, these choices must also be shared.

Learning Activities:

  1. Do Now- Copy down today’s homework assignment in your planner. Open your science notebook to page 79. On the handout, write the vocabulary word “collision,” the meaning of the word as it is used in the text, and a sentence using the word. (Questions 1, 2, & 5)
  2. Reading Comprehension– “Crash Test” (Teacher Read-Aloud/Reciprocal Teaching in pairs)
  3. Unit Cover Page-On p.79 in your interactive science notebook, create a cover page for the unit on Motion and Forces
    • Write the title very large so that it is easy to read.
    • Draw a minimum of 3 pictures that represents the unit.
    • Color the entire page, corner to corner, using colored pencil or crayons- no white paper showing

Homework:
