Week of Sept. 14 & 15


Sound & Vibration

Our line of inquiry this week was “how sounds are created”.

The children learned that energy is needed to create vibration and that vibration makes sound.  We used a drum to feel and hear how sound and vibration are connected.  As we were drumming, Jared noticed that if he placed his hand on the drum he could stop the vibration and the sound would also stop.  




We continued Jared’s observation using triangles and cymbals making loud and soft sounds. The children found when they stopped the vibrations on the instruments, the sound stopped as well. We concluded this activity with comb kazoos.  The children made kazoos using combs and wax paper.  They ended with a rousing rendition of “Twinkle, Twinkle, Little Star” on their                                                 kazoos.
 










When we were conducting our sound and vibration experiments, the children began to notice that they could affect the sounds they heard by covering their ears.  This will lead us into 
next week’s inquiry “how we hear sounds.”

Verdi

Verdi: Catapults

Verdi, a young python, does not want to change.  The last thing he wants his to turn from his beautiful yellow to boring green. Verdi tries to change his colour back to yellow by scrubbing his skin and then covering it with mud. Nothing works.  He notices that the sky is bright yellow just like he used to be. Verdi launches himself from the treetops certain that his flight will change him back to yellow.



How did Verdi fly through the air? What a great opportunity to learn about catapults. Elastics and popsicle sticks were the only materials need to build a catapult.  First the children, used plastic snakes to sail through the area.  It was delightful to hear the excitement and the laughter as the children made  their "Verdi" fly.




I asked the children which would travel farther; a plastic snake or a pompom.  Most of the children though the heavier item, the snake, would travel a further distance.  The children were amazed at how far and how high a pompom could move.
