Objects in Free Fall

Name: Ben Psotka Subject / Course: Grade 11 University Physics Grade Level: 11

Topic: Objects in Free Fall

Instructional Expectations and Opportunities

a) Expectations:

C2.2 conduct an inquiry that applies Newton’s laws to analyse, in qualitative and quantitative terms, the forces acting on an object, and use free-body diagrams to determine the net force and the acceleration of the object

C2.6 analyse and solve problems involving the relationship between the force of gravity and acceleration for objects in free fall

(Ontario Ministry of Education, 2008)

b) Opportunities:

• Collaboration and critical thinking skills are the main focus points of the lab.

Required Resources

• Slow-motion video recording application
• Means to show video to entire class (Smartboard/ projector)
• Slinky
• Lab experiment printed for each student

Content and Teaching Strategies of Lesson

a) Overview/Agenda/Review

• Slinky - What do you see?
• Lab

b) Introduction

Hook: Explain to students that you will drop an extended slinky from a height and ask for predictions on what will happen.

Drop the slinky and ask students what they saw. Video tape the experiment.

Show the video in slow-motion and ask students what they see.

(15 minutes)

c) Subject Content and Teaching Strategies

Students will complete the lab experiment in groups of three. (55 minutes)

d) Consolidation

Assessment and Evaluation

Assessment for learning:

• The teacher will consider student comprehension when they discuss the slinky demonstration and address misconceptions.

Assessment as learning:

• Students are encouraged to make decisions and work at their own pace to complete the lab.

Assessment of learning:

• The teacher will collect completed lab work and mark them. Marks are specified for each question in the lab.
