materials
steel
low density plastic
cork
parafin wax
zinc
acrylic
brass
equpment
graduated cylinder measured to tenth of mL
water
scale
procedure
1.weigh each oject on the electronic scale
2.find the volume using the graduated cylinder
3.devide the mass and you come up with the density
Evidence
Solids
object density
steel 7.6
low density plastic .2
cork .5
parafin wax .47
zinc 14.8
acrylic 1.5
brass 4
Fluids
canola oil .92
water 1
corn syrup 1.38
Claim
steel, zinc, brass and acrylic will will sink to the bottom of the cylinder filled with the canola oil, water, and corn syrup
nothing will fall bellow water but still float on the corn syrup
low density plastic, cork and parafin wax will float on the canola oil
Reasoning
the density shows where objects will float if the density of the object has a lower density than the liquid's the object will float. If the density of the object is higher than the liquid's the object will sink. since the density of steel, zinc, brass and acrylic is greater than corn syrup so they sink. since low density plastic, cork and parafin wax have a lower density than canola oil they float
