Physics Lesson Plans
Week of Jan 28Feb 1
Monday – Day Before Test

Prebell: Complete page 47 of textbook

Complete lab reports from Friday’s lab (10 minutes)

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.

Review and understand the relevance of displacement, acceleration, and velocity equations.

Closure – review conceptual questions that may be on test
Tuesday – Test Day

Prebell – Two short answer questions from test

Retest on Velocity, Acceleration, and Displacement

Students will read through section 23 of textbook and answer questions

Closure – discuss what students learned in the reading
Wednesday – Falling Objects

Prebell – Explain why a hammer and a feather will fall at the same rate on the moon, but not on the Earth

Lecture/Discussion – Free fall acceleration, gravity

Students will compare the equations from the previous unit to the equations for freefall 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.

Problem solving with freefall acceleration. Students will use the equations for freefall acceleration to solve problems. Again these problems deal with reallife scenarios to show relevancy to students.

Activity – Test reaction times. Students will use the free fall equations to determine their reaction times when catching a falling object.

Closure – compare reaction times, determine who had the fastest reaction time
Thursday – Free Fall Lab

Prebell – What is meant by the term “terminal velocity?”

Activity/Lab – Compare fall times and final velocities of various objects

Students will gather various objects and drop them all from the same height. Students will measure drop time for the object.

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.

Students will calculate the final velocity of each object using the equation v_{f} = v_{i} + at (they will use the time that the measured for the t). They will then calculate final velocity using the equation v_{f}^{2} = v_{i}^{2} – 2gy. The final velocities should match. If not, students should brainstorm to develop some hypotheses as to why they do not match.

Compare data for all objects. Determine which objects are most affected by air resistance.

Closure – Complete lab handout. Write conclusions for this lab.
Friday – Falling Objects Quiz

Prebell –

Review Prebell to review for quiz

Quiz on Falling Objects

Closure – Discuss quiz and how similar these problems were to the ones on the test Tuesday
