Number of spatulas used to put salt in water First try measuring the distance of the end of the hydrometer with blutac and thesurface of the water Second try measurin the distance of the end of the hydrometer with blutac and the surface of the water Thirdtry measuring t,he distance of the end of the hydrometer with blutac and the surface of the water Average of the distance ofthe end of the hydrometer with blutac and the surface of the water
No salt 4,3 5 4,3 4,53
2 spatulas of salt 4,5 6 3,9 4,8
4spatulas of salt 4 4,3 4,9 13,2
6 spatulas of salt 3,8 4,8 4,5 13,1
8 spatulas of salt 5 5,1 5 15,1

(Note: 1 means no salt 2 is2 spatulas 3 is 4 spatulas 4 is 6 spatulas and 5 is 8 spatulas I don’t know how to change it sorry)

Conclusion:
We didn’t needto do a hypothesis but seeing the experiment I would have said that increasing the amount of salt would have made the hydrometergo higher but seeing my results I would have been wrong because in my results sometimes the trial with no salt did more than with6 spatulas. I don’t know what went wrong with this experiment but I think this happened to everyone in the class. I think that fora future experiment we should get real hydrometer because I think that because we made them they weren’t too reliable.
