Buoyancy-Lab Report

1.1 Defining the problem and selecting the variables

In this investigation I aspired to ascertain out how the buoyancy of an physical object depends on the tawdriness of water supply it displaces. My research question thence is:


How does the change of an objects slant in water depend on its the great unwashed.

More precisely How does the buoyancy of an object depend on the volume it covers in water.

My variables were:

self-governing variable: The volume of an object.
Dependent variable: The buoyancy of the objects.
apply Variables: 1)The liquid I used.
2)The way the objects were dipped into the water.
3)The density of the object being held in the water.


1.2 Controlling the variables

I used the spare-time activity apparatus for the experiment:

1.A bucket filled with water.
2.A weighting leave off with supererogatory weights that can be put on.
3.A weight
4.A ruler
5.A stand for the weight to be hanged on

My independent variable was determined by the volume of my weight bar, I measured the volume by measure its height with a ruler and therefore finding the stadium of its surface area. I manipulated the volume of the object by adding additional weight.



This consistently increased the objects height by 0.4cm so that I could determine my volumes easily.

My dependent variable was determined in two phases. First I would measure the objects weight using a weight and because while the object was in water, because it was held by the weight on a hook I could then also measure the object weight with the same weight. The original weight of the object minus its weight in water would then equal to the buoyancy of the object.

The control variables were determined like this: 1) I used water only. 2) The objects were held in so that their entire volume was in the water. 3) I suspect that if the density is too downhearted a problem will arise, I will therefore use weights which have a reasonably high density. withal I will use...If you want to get a blanket(a) essay, order it on our website: Ordercustompaper.com
