1. Topic-
|
|
|
2. Content-
|
| Motion, Distance, Displacement, Vectors, Velocity, Speed, and Graphing |
| |
|
3. Goals: Aims/Outcomes-
|
1.Relate velocity to displacement and time
2.Gather data
3.Graph data |
| |
|
|
4. Objectives-
|
1.The students will review how direction plays a role in velocity
and the proper way to create a graph.
2.The students will assembly the zip line between to chairs to contain
a balloon on a straw.
3.The students will graph the data with respect to Distance and Time |
| |
|
5. Materials and Aids-
|
| Stop watch, Balloon, Fishing line, Straw, Chairs, Tape, Scissors,
Meter stick |
| |
|
6. Procedures/Methods-
|
|
A. Introduction-
1.Teacher introduction explaining end goals and expected behavior
2.Demonstrate the set up and how to gather data
3.Pass out materials |
| |
|
|
B. Development-
1.Begin setup of the lab
2.Trial runs to test the set up and gain first hand experience with
the process |
| |
|
|
C. Practice-
1.Begin gathering data
2.The balloons will be launched down the zip line while the stop watch
keeps track of the progress of time.
3.Once the balloon has stopped, the meter stick will be used to gather
data about distance. |
| |
|
|
D. Independent Practice-
1.The students will research other ways to gather data on velocity.
2.The students will extrapolate the acceleration from the graph of
velocity they create. |
| |
|
|
E. Accommodations (Differentiated Instruction)-
1.Teacher guidance with examples of technique and graphs
2.Group work
3.Extra time for complications with the balloon zip line |
| |
|
|
F. Checking for understanding-
| 1.The balloon zip line must be set up accurately in order to gather
data. If the students gather data and the technique is appropriate
then the students understand what is happening. |
| |
|
|
G. Closure-
1.The set up needs to be broken down and all the materials taken
back up
2.Review of the terms used in the lab and connection with the experiences
of the lab |
| |
|
7. Evaluation-
|
| The graph will act as the Evaluation for this lab. The graph will
be graded according to the T.A.L.K.S. principle |
| |
|
8. Teacher Reflection-
|
This lab is a lot fun. The students really enjoy watching the balloon
zip along at speed. I highly recommend using the fishing line but
the straw is as sturdy as I would like. The straw needs to be long
to keep the balloon from getting hung up on the line but it needs
to be light and sturdy as well. I don't know what would be a good
substitute with such requirements.
The other issue is that the balloons go further than the zip line
extends and the balloons bump into the end chair. The zip line needs
to be exceptionally long in order to accommodate the full distance
the balloon can travel. |
