Learning Purpose
1.
The students can
determine the control variable, response
variable and manipulation variable of the experiments about the influence of
the distance to the travel time
2.
The students can design experiments to find the influence
of the distance to the travel time.
The Problem Formulation
1.
How is the
relationship between the distance to the travel time?

2.
Load 100 gr
3.
Pulley 1 unit
4.
Strap 1 meter
5.
Ruler 1 unit
6.
Stopwatch 1 unit
Procedure
1.
Formulate the operational definitions of variable
Formulate the manipulation variable, the response
variable and the control variable along with the operational definition of
variables.
Manipulation variable :  |
Response variable : |
Control variable :
2.
Design the
experiment. Write the planning of
experiment to test your hypothesis, based on the variabels that you have
formulated.

3.
Make the tables and graphs. Make a chart to record the data that you got. Make a
chart to showing the relationship between manipulation variables with the
response variable based on the data that you have got.
Discussion and
Analysis
1.
Formulate the
conclusion. Based on the data
and the chart above, what is the conclusion that you get?

3.
Doing the calculations. The slope of the graph distance on
time travel is acceleration. Calculate the acceleration!

Application
Taking water from the well
using a pulley. At the time of taking water from the
well we exert a force on the pulley by pulling the rope with connecting the pulley. So this force is will
drive the pulley. Can this system have zero acceleration?
