Hello World.

Today we did a science experiment of sound,we took a cup and covered it with plastic wrap.

then we put string around the plastic wrap and then tied it so the plastic wont fall in the cup and then we took tuning forks and hit them on our desks and then we put it on the salt.

The salt started to shake.

 

And our second project was taking our plastic wrap an the strings off the cup and then we add water into the cup and then we take the tuning fork and bang it on our desk’s and then put it in the water and then when i did that the water just flew in the air.

 

 

Hypothesis:1st Experiment: In my hypothesis i wrote i think its the vibrations.2nd experiment i thought the water would just stay there but shake just a little bit.

 

Conclusion:1st Experiment the salt shook off the cup and it was really fun 2nd Experiment the water flew in the air really high and i filled up my cup even more and it flew even higher
