My lab report

Lab Report Making waves  
1/19/2011
Guiding Question:How do water waves affect the objects floating in the water
Hypothesis: I think as the wave Hits the Boat and the floating objects in the water it will move them farther, And as i hit the water slower the boat and the object will not turn they  will rock.
Exploration  ( PLAN & DO A TEST):
(Materials) : 1. I will need a big bucket of water
                2. Make a tin foil boat and some building
                3. I will need sand
                4. A lot of water
                5. marker
(Procedure) :
1.  First you have to make a boats  out of tin foil. Second you have to take a big bucket, and insert water in it. Put the objects that you made in the bucket, Take a marker and start hitting the water and observe the boat and the water if nothing is happen take a bigger object and do the same thing, you will see as you take the bigger object you will see that the boat will flip or hit the bucket.         
IV.  RECORD & ANALYZE:
When i hit the water with the glue stick slowly it takes more time to get to the end, and as i hit stronger the faster the ball is traveling.
           A.  Data Tables:
                       Give proper title of table and column headings
Object:Low Frequency TimeHigh
Frequency
Time
Ping-Pong1 Hz21.75 Hz15.7
Wooden stick1 Hz51.45 Hz21.7
Small boat1 Hz43.55 Hz16.8

                       Use an appropriate orientation
                       Make correct computations
                       Use units of measure
                       Observe significant figures and rounding-off
                           rules
           B.  Graphs: Give a proper title and a legend for each  
                             axis
                       Use an appropriate orientation
           C.  Analysis of Data: As i hit the water harder the faster the boat and the other object are going. But as i hit slower the slower the boat and the objects are slower and hitting the edge of the bucket.
IV.  Concept Acquisition (CONCLUSION): In conclusion i think this wave lab will help me a lot.I can see that this unite was Cindi hard. I learned a lot of things. It was so hard trying to do all of the calculating and putting all of the data analyses on the
I learned a lot for a very short time. The int resting thing is how each material accede different. One pore the more you swing there is less the ‘’the wave is made’’
V.  Concept Application (FURTHER INQUIRY):  The only thing that i would change was my guiding question because i was in a hurry and did’t have much time to think. Every thing El's was good

  1. You did very well with this lab. the guiding question was good and you were able to make a solid hypothesis. Some areas of the procedure were not coherent and should be broken down into numbered steps. Part of the data was missing for the higher frequency, but your analysis was supported by your observations so you were able to answer the guiding question. Remember a lab report is not a place where you write your opinions or a reflection but is evidence based. Overall, good job.
