My science Project

We are doing a science fair on december9. We are doing it in the gym. My project is how do human vocal cords change the pitch of sound. E'deviyon and JaVeon are in my science fair group. We chose this project becaue it is interesting we like music.It looked easy at fist.We were doing a different project ,but we canged it.

Why I chose it - I chose it becaues it sound intring to us.E'deviyon chose it. We agreed with it so he pick it. We are doing goood so fair. We are almost done with the board. So we have to get done.

Hypothesis - I thought the bigger rubber band will make the higher sound, but the little rubber band made the higher sound. The bigger rubber band made the lower sound becuase it is louser than the little one.

Human vocal cards will effect the pich of sound. When you sang you change your sound. My vocal cord will caneg my pitch of sound to. My materials are a block of wood,2 nails.2 rubber bands. I will hammer the nails into the block of wood and put the rubberbands around the nails. I need to put the rubber bands on the nails. I got to pluk the rubber bands with a penicle to make a pitch. The different sound will proov the little rubber band will make the higher sound.The big rubber band will make the lower sound.

I need to bring the exprniment to school for the pic. for the borad. It will be fun becaue we can get together and take a pictucher. together. JaVeon is going to take the pic. We are going to take a pictucher. of the materials too. It will be exciting becaue we can get together. I have brung the exprniment to scool. We took the picture all ready.We have to glue the the pic to the board.

We swiched a round E'deviyon has the board and JaVeon has the exprinment.The sients fair is comeing up. I thank we will win the science fair and get a price. We are going to swich around again. We are going to be the wining team.
