Thursday, 3/14/19- A Day- Block Schedule Periods 2, 4, 6, & 8

Remember: As long as you act like a scientist when we do science, you will be treated as a scientist and conduct investigations. If not, you get to watch the rest of us do science.

Lesson Question:

If speed has an effect on the impact of collisions, what happens if an object changes speed?

Learning Tasks:

  1. Do Now– Copy down today’s Home Learning tasks in your planner. Get out your science notebook and open to page 57. Write your name on the piece of paper and explain how deceleration is related to acceleration.
  2. Investigation– Acceleration- If speed has an effect on the impact of collisions, what happens if an object changes speed? Review Science Safety Regulations and complete Lab Safety Checklist- Before You Begin. Also, review Group Member Responsibilities. Get an accelerometer and clipboard. Go to the lobby in front of the auditorium. Practice holding the handle of the accelerometer and keeping it steady as you walk. When you are ready, walk in a straight line and gradually decrease your speed. Next, walk in a straight line and gradually increase your speed.  Then walk in a straight line and start changing directions. Finally, walk around the room and make any other changes in motion that you can think of. For each situation, draw arrows to show how the metal washer moves and describe your observations in words next to each diagram. Return to the classroom and complete the Reflect and Apply and Journal questions. Also, complete the Lab Safety Checklist-After Lab is Completed.
