WHAT SOUND IS THAT?
TRAVELING
SOUND
Objectives:
- Observe sounds made by objects
when dropped
- Create a code of sounds to send
a message
The students listen to sounds as
they are dropped out of sight. They attempt to identify each
object by the sound it makes. The students then use the sounds
to make a code and send a message.
Materials You will Need:
- several object that make different
sounds. I like to have a silent sounding object also. I sometimes
use a sponge or a cotton ball.
- Drop Box or cylinder for each
group of 4 students. I use a large deep box to drop the items
into. I place it o the desk. This gives the sounds a hard surface.
Directions:
- Have the class shut their eyes
and drop an object. Ask the class to open their eyes and guess
what it was that you dropped.
- Have some students talk about
some unusual sounds that they have heard. (A homework assignment
could be to bring in photo's of unique sounds or a tape recording
sounds.)
- Demonstrate the drop box to the
students. Explain that each group of 4 students will work in
pairs. One group will close their eyes and listen while the other
pair of students drops the object.
- Now have the students get into
their groups of 4. Each group should have two sets of identical
objects to drop in the box. I have used blind folds with older
children. I have found that some primary children do not like
to have their eyes covered so it is up to the teacher.
- Tell the students that they should
take out the object they drop each time without the other students
seeing it.
- Start the challenge.
- One team selects an object and
drops it into the drop box, not letting the other team see it.
- The other team says what they
think the object is. They then find it in their own set and drop
it into the drop box.
- Now the other team drops their
object again and they see if it is the same.
- Do this for 5 minutes.
Part 2; Making Sound Codes
- Discuss with your class what a
code is. Give them an example. (It is a set of signals or symbols
that represent letters. My students are used to doing codes in
their math class. The answer to a problem is a letter that spells
out a word.) Some examples are braille, sign-language alphabet,
musical notes etc.
- Students work in their groups
of 8 (4 and 4) and decide which of their drop objects are the
easiest to figure out when they are dropped. Then they should
take one of their sets of drop objects and place them on a sheet
of paper. They then decide what letter should be by each object.
They must choose letters that can be used in many different words.
(When students get stuck I give them hints. I have used the letters
'm'e't's'a'r'. These letters can make many words. Be sure they
have some vowels.
- Now the students send messages.
Have one group close their eyes. (Or cover them) The other group
should drop their objects being careful to wait a few minutes
between drops. As they drop they should write down the word they
intended to make.
- The other group that closed their
eyes now take a few minutes to figure out the word. They write
it down and show the other group that dropped it. If they got
it right they get 1 point. Now the other group closes their eyes
and the activity repeats until the teacher says times up. (I
let it go on for 10 minutes.)
Debriefing the lesson;
- Have the students write in their
journals, lab notebooks or whatever you use "What have they
learned?" It could include the following:
- What does sound tell you?
- How are the ways they told the
sounds apart?
- What are the best objects to drop
codes?
- What sounds hurt your ears?
- What sounds make you feel good?
How
Does Sound Travel?
Objectives:
- Sound can travel through solids,
water, and air.
- Sound receivers detect sounds.
Ears are an example of a sound receiver.
The students will work in groups
of 4 on mini-activities in centers that they rotate through..
Each activity will introduce a sound source and a medium of sound
travel. Students observe and compare how sound travels through
solids, water, and air. They record their observations in their
lab journal, notebook or what ever you use.
Materials you will need:
Activity #1
- 2 tuning forks
- 6 pieces of tag board, 50 by 35
cm long
- 12 rubber bands
- 12 paper fasteners
- 2 wood blocks
Activity #2
- table
- toungue depressor
Activity #3
- basin of water
- stethoscope
- alcohol for cleaning the earpieces
after each child uses it.
Directions:
Activity # 1
- The teacher prepares six pieces
of tag board into listening tubes and secures them with paper
fasteners at each end and two rubber bands in the middle section.
Place the three listening tubes, a tuning fork, and a wood block
in each of two plastic bags and label the bags with the number
1.
- Show the students how to strike
the tuning fork on the wood with a medium force, enough to make
a strong sound without damaging the fork. Emphasize how to handle
the fork by the stem and how to orient the fork when striking
the wood. let them know these are scientific instruments and
not toys.
Activity #2
- The students tap or scratch the
underside of a table with their ear on the top side. They listen
to the sound.
- The students put a tongue depressor
on the table. They let one end hang over the end of the table.
and one end on the table. Then the students plunk the depressor.
The student listens to the sound it makes. They can also listen
to the sound it makes hitting the table as it vibrates in the
air.
Activity #3
- The students will listen to sounds
under water. The students place a stethoscope under water in
a basin or fish tank.
- As one student listens the other
students claps their hands outside the basin of water.
- Next the student snaps their fingers
under water.
- Repeat the steps with each student.
Debriefing the Activities:
- Have the students write in their
journals, lab notebooks or whatever you use "What have they
learned?" It could include the following:
- Do fish make sounds
under water?
- What other times have
you heard sound travel through solids?
- Did you hear sound through
the table or water better?
