Semi Open-Ended Work Sheet Example
Problem Sentence: Haydar’s Uncle was driving his car too fast. At the same time he forgot to wear his seatbelt. While he was driving on the road, he suddenly came across a dog. He braked in order to not hit the dog, but, since he did not wear his seatbelt, he flew out from the car’s windshield. What must Haydar’s Uncle do in order to not fly out and have accident? How can you prove the reasoning of your answer?
My assumption or hypothesis:
If Haydar’s Uncle was driving slower, then he could not have had accident and flown out the window.
a. What are our variables?
The variable which we will change: Velocity of the body
The variable which we will measure: Distance between the car and the place where the body flew out.
The variable which we will keep constant: Mass of the body.
b. How will I perform the experiment?
c. How will I collect my data? (Which measurement tool will I use?)
To measure the distances, we can use a ruler.
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?
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?
