Jan 28 - Feb 1

Physics Lesson Plans

Week of Jan 28-Feb 1

 

Monday – Day Before Test

  1. Pre-bell: Complete page 47 of textbook
  2. Complete lab reports from Friday’s lab (10 minutes)
  3. Discuss lab and the equations used to determine the acceleration of the trucks.  Also, will discuss errors that the students committed during the lab.  Students must understand WHY their errors affected their findings.
  4. Review and understand the relevance of displacement, acceleration, and velocity equations.
  5. Closure – review  conceptual questions that may be on test

 

Tuesday – Test Day

  1. Prebell – Two short answer questions from test
  2. Re-test on Velocity, Acceleration, and Displacement
  3. Students will read through section 2-3 of textbook and answer questions
  4. Closure – discuss what students learned in the reading

 

Wednesday – Falling Objects

  1. Prebell – Explain why a hammer and a feather will fall at the same rate on the moon, but not on the Earth
  2. Lecture/Discussion – Free fall acceleration, gravity
  3. Students will compare the equations from the previous unit to the equations for free-fall acceleration and note their similarities.  It will be easier to remember the equations if the students realize they are only variations of equations they have already used.
  4. Problem solving with free-fall acceleration.  Students will use the equations for free-fall acceleration to solve problems.  Again these problems deal with real-life scenarios to show relevancy to students.
  5. Activity – Test reaction times.  Students will use the free fall equations to determine their reaction times when catching a falling object.
  6. Closure – compare reaction times, determine who had the fastest reaction time

 

Thursday – Free Fall Lab

  1. Prebell – What is meant by the term “terminal velocity?”
  2. Activity/Lab – Compare fall times and final velocities of various objects
    1. Students will gather various objects and drop them all from the same height.  Students will measure drop time for the object.
    2. Students will use the equations provided to calculate what the drop time should be and compare them the drop times they recorded.  If there are any discrepancies, they must explain why the discrepancy occurred.
    3. Students will calculate the final velocity of each object using the equation vf = vi + at (they will use the time that the measured for the t).  They will then calculate final velocity using the equation vf2 = vi2 – 2gy.  The final velocities should match.  If not, students should brainstorm to develop some hypotheses as to why they do not match.
    4. Compare data for all objects.  Determine which objects are most affected by air resistance.
  3. Closure – Complete lab handout.  Write conclusions for this lab.

 

Friday – Falling Objects Quiz

  1. Prebell –
  2. Review Prebell to review for quiz
  3. Quiz on Falling Objects
  4. Closure – Discuss quiz and how similar these problems were to the ones on the test Tuesday
