Standards and Benchmarks (Physics of Sound)

Standards:
11-A Know and apply the concepts, principals and processes of scientific inquiry.
12-C Know and apply concepts that describe properties of matter and energy and the interactions between them.
Benchmarks Assessed:
    Use activities to understand the components of sound. (12-C)
    Use sound producing materials to develop the central idea of vibration as the
    source of all sounds. (12-C)

Observation

    I have chosen this means of assessment to have factual descriptions of meaningful incidents and events that occur during group work of the science activities. This method will be used mainly to describe social adjustment, since this is a skill that we are beginning in third grade group activities.  I have developed a class system of recording information on index cards that are taped to a clip board.  With this system, I can easily walk around the room and jot down anecdotal notes as I see them.  After reviewing the index cards, I can conveniently see who I need to observe.  This process will help me determine how and if students are following the scientific procedures which is measured on our quarterly report cards.

Reflective Questions Sheets/ Physics of Sound

    The Reflective Question Assessment is made up of written questions that ask students to recall information and to process or integrate this information to give answers to a situation.  Students will do the Reflective Question Sheet at their own desk in a time period of about 20 minutes.  If individuals are below grade level in reading, I would read the test orally.  Some students with IEP's may need additional time or have the alternative to take the test with the special ed. teacher.

Pictorial Assessment/Physics of Sound

    This type of assessment is made of up tasks different from standard fill-in, multiple choice, one word answer tasks.  This type of assessment requires students to explain how different musical instruments produce sound, to choose from a set of instruments which produce the highest and lowest sounds, and to tell why.  The test should take about 20 minutes.  If their are individuals in the class that are well below grade level in reading, I would read the test aloud to them. Additional time may be given to those with IEP's.

Pictorial Assessment of Wind Instruments:
Various wind instruments are shown.  They vary in size.
1.  How is sound produced by these instruments? ___________________________________
2. Put an L under the instrument that can play the lowest notes.
3. Why do you think it can play the lowest sound? __________________________________
________________________________________________________________________
4.  Put an under the instrument that can play the highest notes.
5.  Why do you think it can play the highest notes? _________________________________

Physics of Sound/ Hands-on Assessment

The Hands-on Assessment will allow individuals to manipulate scientific tools (in this case, sound equipment), and show how they can use the scientific methods of observation and discovery.  These tasks are different than the ones assigned during the unit.  There are three hands-on tasks at three different stations.  Students will go to each of the stations and complete the tasks that are written out on a Hands-On Student Assessment Sheet.  After an introduction of the three stations, students will take turns to complete each station.  Each station would take about five minutes to complete.

Station 1- Tuning Fork
At this station there would be:  One tuning fork, one wood block, and a tin can covered with a cut piece of balloon secured with a tight rubber band, some lima beans (on top of the can).

1.  Strike the tuning fork against the wood block to make a sound.
a. Explain why you continue to hear the sound for a long time.___________________________
__________________________________________________________________________
b. Other than striking the tuning fork harder, how could you make the sound louder?
__________________________________________________________________________
2. Make sure the beans are on the rubber that is covering the can.  Strike the tuning fork on the wood  block again.  Touch the rubber cover on the top of the can with the tuning fork.
a.  What did you observe?_______________________________________________________
b. Why did this happen? ________________________________________________________

Station 2- Kalimba
At this station a kalimba will be set up with one popsicle stick under the wooden dowel. (Students had experience with the kalimba at earlier assignments).  Another popsicle stick will be there for students to add.
Directions:  Loosen the nuts on the kalimba and slide a second wooden stick under the dowel so that the two sticks will produce different sounds.  Tighten the nuts.  Play the bars with your fingers.
1.  Draw what the two sticks would look like.
     a.  Put an "H" by the stick on your picture that makes the higher sound.
      b.  Explain why that stick makes the higher sound. ________________________________
_________________________________________________________________________
2.  Put a third stick in the kalimba so that all three sticks produce different sounds.  Draw what the three sticks would look like.
     a.  Put an "L" by the stick in your picture that makes the lowest sound.
     b.  Explain why that stick makes the lowest sound. ________________________________
_________________________________________________________________________

Station 3 - Rubber Band
Directions:  Get the plastic container with a rubber band around it.  Pluck the rubber band.  Listen to the sound it makes.
Change the rubber band to make a higher sound.  Describe and draw a picture to show what you did to the rubber band to make the higher sound.
