Making sounds with simple instruments and understanding the importance of our ears was the focus of teacher workshops at the Primary Science Programme in Philippi
The Primary Science Programme (PSP) offers in service teacher training workshops for F phase teachers in Life Skills, Numeracy, Literacy and for I phase teachers NST, Maths, Languages and Social Sciences.
Our voice box is our very own built in musical instrument
We all have a musical instrument in our throats and we all use it without even thinking.
By changing the size of our voice box and vibrating the vocal chords we make different sounds.
Our bodies love to move and dance together
It was easy to join in the rhythm of this game and learn counting and pattern recognition skills without even realizing it.
Each one of us is an energy system
Our body needs energy from food to survive.
We get this energy from food we eat. Much of our food is made from plants.
Where did they get the energy? ….light energy from the sun!!!
Our bodies are constantly converting energy into different forms.
In order to make sounds we have to make something move and vibrate.
We make sounds with our bodies by clapping our hands, stamping our feet, thumping on the table, humming, singing, shouting, screaming, whistling. The more energy we put into making the sound the louder the sound.
Simple musical instruments
We can also make sounds with simple things to make a musical instrument.
blowing a cut straw.
a long straw makes a low note and a short straw makes a high note
An ice-cream container guitar to strum
Thick elastic bands have more material to vibrate and therefore make a lower pitch sound when plucked.
Thin elastic bands make a higher note.
Coffee jar piano
Tapping the bottles with a metal item makes a tinging sound.
Tinging the full bottle makes a low note while tinging the empty bottle makes a high note
The empty water bottle in the background makes a wonderful low boom
Everybody enjoyed shaking, rattling, strumming, blowing, twisting in order to make an interesting sound.
Making our own instruments
The challenge was to make a simple instrument out of recycled materials that could make a low and a high sound
I know that these teachers will create some wonderful lessons in their classrooms. They may be very noisy but then that is what sound is all about…….learning to make music out of noise by making patterns
