Closed Ended Work Sheet Example
Problem Sentence: Can you measure your friend’s walking speed? How?
My assumption or hypothesis:
I can find his/her speed by measuring the distance that my friend would walk and the time that he/she covered this distance.
a. What are our variables?
The variable which we will change: The distance covered
The variable which we will measure: The time spent for the distance that we covered.
The variable which we will keep constant: Walking by equal length and equal time steps in each try.
b. How will I perform the experiment?
One of our friends will walk the distances of 2 m, 4 m, 6 m and 8 m respectively which we marked at the classroom in equal steps, and each time we will measure the time which he/she covered the distances. c. How will I collect my data? (Which measurement tool will I use?)
To determine the lengths, we can use a ruler.
And to measure the walking time, we can use a watch that we can read the seconds, a cellular phone, or a chronometer.
1. Let’s create a table which we can take note the data that we collected while doing experiment.
Let’s create a table containing the covered distance, time, and velocity columns.
2. If we can display our table in graph, then let’s display it.
3.Which results did we obtain after doing this experiment? What do our graphs tell us?
4. Does our result obtained verify our answer at the beginning?
5. Did we encounter an unexpected result?
6. At the end of this activity, what did you learn that you did not know before?
7. During this activity, which knowledges and skills that you had before did you use?
