Week 6- Entry 1

REPORT   Eihab Taouk

Title: This investigation will test “The effect of swimming attire on the speed of a swimmer”. Furthermore our results will be discussed analysed and diagramed to give you a clear indication of how and why our results were achieved

Aim & hypothesis: In saying this, the aim is to investigate the effect of swimming attire on the speed of a swimmer and to show how my experiments & results relates to everyday life as well as why my research is important.

Method:

Step 1: Speak to the manager of the Roseland aquatic centre



Step 2: Pay for entry




Step 3: Dress in attire:



• Jeans and hoody jumper



• Swimming shorts



• swimsuit




Step 4: prepare stopwatch (To time the swimmer from start to finish)




Step 5: One person stands at the start of the pool to time the swimmers take-off while another person stands at the end of the pool to time the finish point




Step 6: swim 50 metres whilst dressed in attire.



Step 7: Video camera and/or digital camera the swimmers performance for evidence & further investigation.



Step 8: Swimmer gets out of the pool, dry’s himself and gets dressed for his next attire.



As mentioned above.




Step 9: Results of swimmers performance are collected & recorded on an excel spread sheet (laptop).





Step 10: Results are printed on hard copy for further research i.e comparing results, thesis, graphs & conclusions




Step 11: blog the results for the current week



Step 12: Plan the next experiment for the following week







The equipment used for this science assignment includes:

• Roselands 50m (metre) pool (swimmer will swim from one end to the other)

• Stopwatch(To time the swimmer from start to finish)

• 2 people at each end of the 50m (metre) pool. (For start and finish time)

• Swimming with different attire (clothes) include:

-Jeans and hoody jumper

- Swimming shorts

-swim suit

• Video camera/digital camera

-video camera(Is used to record the swimmer)

-Digital camera(For taking photos)

• Pen/Pencil/eraser(Used to record results)

• A4 papers (Is used for writing the results for your experiment)

• Laptop (To search up pictures, information, diagrams etc.)

• Printer (The printer is used for all the pictures and information I need)

• Phone (To call manager for the aquatic centre)

Risk assessment: Our safety measures that we thought about before our experiment include:

• Swimmer might drown.



• Wet concrete surfaces might cause injury.



• Swimmer might collide with other regular swimmers.



• The swimmers health's protection and the maintenance of good safety.



• An Aquatic Centre that has swimming pool regulations with a valid tool for health promotion.



• Swimmer might be allergic to Chemical disinfectants such as chlorine.





According to our topic “the effect of swimming attire on the speed of a swimmer” the following results were achieved from the experiment


Swimmer swam 50m (metres) in attire (jeans & hoody jumper) and


the results were: 90s (seconds)

Swimmer swam 50m (metres) in attire (swim suit) and the results were: 54s (seconds)

 

 

Swimmer swam 50m (metres) in attire (swimming shorts) and the results were: 60s (seconds)

ATTIRE LENGTH RESULTS








ATTIRE                            LENGTH                      RESULTS

Jeans & Hoody Jumper    50 Metres                     90 Seconds



Swimming Shorts             50 Metres                        60 Seconds



Swimsuit                       50 Metres                                54 Seconds



Note: The same swimmer swam 50 Metres in every attire.






From the table we can see that jeans & hoody jumper achieved the slowest swimming performance with 90 Seconds whilst, swimming with shorts finishing with a speed of 60 seconds.Leaving us with the ultimate attire (swimsuit ) which was the fastest effect on the swimmer with a stunning speed of 54 seconds.




The results can give us a sign that the attire has a direct effect on the swimmer because it can delay or increase the swimmers speed. For example; when the swimmer swam with the jeans & hoody jumper attire, it absorbed the water causing the clothing to be heavier due to wetness .For this reason this slowed down the swimmers speed as the material is made out of cotton.



As for the swimming shorts the swimmer had a smoother swim compared to the jeans & hoody jumper but slower by 6 seconds compared to the swimsuit. Although the swimmer bares most of his skin, the shorts itself acted as floaties because air bubbles entered the polyester shorts causing the shorts to float slightly.



With a spectacular speed of 54 seconds, the swimsuit was the best attire on the speed of a swimmer and this was due to the make of the swimsuit. The swimsuit tucks your body and acts as a shield to water and air bubbles, so as the swimmer swims the swimsuit does not absorb water therefore achieving a faster speed.
