guiding question:how will the wave effect the needle and the paper?
hypothesis:i think that when i do the disturbance the needle will fall from the paper and float alone whit out the paper under it.
materials:tub,water,needle,paper.
| waves made by | hand | |
| trial 1 | the needle sank whit the paper | |
| trial 2 | it sank again | |
| trial 3 | i saw it was not working |
conclusion:at the end of a lot of trials i understood that it was not working so my lab did not work at the end so i gave up.
