Objective:  make your own objective based on the given procedure...

Pre-lab activity:

1.     Read concepts related to the given activity.

2.     Read thoroughly the given procedure.

3.     Prepare the necessary materials.

Materials:

5 test tubes

1 Test tube rack

Metric ruler

Container of water

Rubber bands

box

Laboratory Activity 1:

1. Place the test tubes in the test-tube rack.

2. Pour different amounts of water into etch test tube.  Use the metric ruler to measure the height of the column of water in each test tube.  The heights should be as follows: 2 cm, 4cm, 6 cm, 8 cm, and 10 cm.

3. Blow air across the top of each test tube.  Observe the pitch of the sound you hear from each test tube.

Post-lab activity 1:

Questions

·         How does the height of the water affect the pitch of the sound?

·   _____________________________________________________________________________________________________

·   Which test tube had the highest pitch?____

·         Which test tube had the lowest pitch? ____

·   Draw a picture of the 5 water test tubes.

·   Mark the highest and lowest pitch test tubes. 2cm     4 cm         6 cm       8 cm     10 cm

 

Laboratory 2:

1. Each group will receive an assortment of rubber bands and boxes over which you can put the rubber bands. 

2.  Pluck the rubber bands and compare their sounds. 

    

Post-lab activity 2:

·         Which ones sound lower? _________________________________________________________________________

·         Why? ____________________________________________________________________________________________

·         Compare the sounds a rubber band makes when it is stretched tightly and loosely.  Explain how they are different.

·         _________________________________________________________________________________________________________

Follow- up activity:

The sound produced by blowing over the top of a partially filled soda pop bottle is the result of the closed-end air column inside of the bottle vibrating at its natural frequency. Keri Atune uses four bottles (labeled A, B, C and D) with varying amounts of water (and thus, air) in order to play a song. Express your understanding of closed-end resonance by filling in the table below.

Conclusion:

activity in sound wave

• This is a group activity. I will provide the rubber bands but make sure to bring other materials before the scheduled date of activity.
• You can buy your test tube @ Berovan, beside rose pharmacy or mercury drugstore (Php10-15)

• Be ready with your group activity notebook (graphing) for this.

• For II-Camia and II-Jasmine, you will perform the activity on Monday (8-1-11) while II-Sampa will have it Tuesday (8-2-11).
• See you all @ the phys lab.

concept paper format

IMPROVISED SONOMETER

CONCEPT PAPER

What is a concept paper?

}                  A short summary telling readers  what a project is about, its significance and how it will be carried out

}                 Concept papers typically range from 2 to 5 double-spaced pages (500 to 1250 words), not counting bibliographies/references.

What are its contents?

1.       Title of the Proposed Project

2.       The Body of the Concept Paper

a.        Introduction:

i.                     Clear description of the research topic

ii.                    Significance of the proposed topic (here are some questions worth pondering)

·         What good would come of this study?  Who would benefit from its results?

·         Why would this study be worth anyone’s time?

iii.                  Proposed statement of the problem (main and subproblems)

b.       Brief Literature Survey

·          Include brief descriptions/summaries of what other researchers (or experts on the field) have to say about the topic (at least 2 from primary sources, at least 2 from secondary/tertiary sources) .

·         Connect your problems to existing literature (scientific).  Some questions to ponder:

n  How original is my own idea?

n  What results can my own proposed study offers that are not yet available in the field? 

c.       Discussion of the feasibility of the proposed study

·         Are the needed materials available in the locality?  If not, where is the nearest available source?

·         Is the time needed to finish the study possible?

·         Will you have the money to fund the study?

d.      Closing statement (A statement of the limitations of this research, specifically the things that it cannot discover (and why).
