Subject: Chemistry
1. Topic-
Can you pass that?
The effects of spin on a volleyball when served
 
2. Content-
Overhand Serve: A serve in volleyball in which the ball is tossed into the air about above the server's head and is hit with the arm extended over the head.
Floater Serve: A serve in volleyball in which is the same as an overhead serve but you do not snap your wrist when serving instead you serve and stop when when you get connection with the ball which causes it to drop unexpectedly.
Top Spin Serve: A serve in volleyball in which you do the same serve as a overhead serve but when you make connection with the ball you hit the bottom of the ball and snap your wrist to make the ball go in a down spiral motion.
Jump Serve:
 
3. Goals: Aims/Outcomes-
1.The goal is to see which serve is most effective when served.
2. My hypothesis is: I think the floater serve because of its unnatural movement when served in the air making the serve look farther but will drop soon because of the way the ball was hit with an amount of force therefore I believe it is the most effective when served.
 
4. Objectives-
The main objective is to see how many volleyball serves by each serve will be returned correctly.
 
5. Materials and Aids-
Volleyball
Target
Returner (subject)
Data table
 
6. Procedures/Methods-

A. Introduction-

1.First I will gather the materials to do the procedure.
2.I will start practicing my serves so the serving is constant when I start my experiment.
 

B. Development-

I will make a chart of the number of serves that would be returned or not and I will make four charts for each serve.
 

C. Practice-

1.Serving each type of the four serves
2.Overhand Serve
3.Floater Serve
4. Top Spin Serve
5. Jump Serve
 

D. Independent Practice-

1.I will serve at a target, each type of serve 25 times for a total of 100 serves.
2. Each time the subject cannot pass the serve back it will equal to one miss served and will continue to do that with each set of serves.
 

F. Checking for understanding-

I will be serving 4 different types of volleyball serves 25 times with a total of 100 to see which serve is the most difficult to return correctly
 

G. Closure-

1. I served at the subject 100 times, each serve serving 25 times.
2. Filled my chart with the results
3. The Overhand Regular serve had 25 serves and had 23 returned correctly.
4. The Floater serve had 25 serves and had 13 returned correctly.
5. The Topspin serve had 25 serves and had 20 returned correctly.
Finally, the Jump serve had 25 serves and had 15 return correctly.
 
7. Evaluation-
The Floater serve was the most difficult serve to return correctly because of my reason in my hypothesis that it will be most difficult because it looks like the serve will go deep into the court when it drops unexpectedly and confuses the opponent.
