Draw a line of best fit through the points. The gradient of the graph = \(\frac{mass}{volume}\) = density of water. Calculate the gradient of the graph and hence the density of water. As for the ...

Independent Variable is the volume of the object. Dependent Variable is the mass of the object. Control Variables are the material of the object, room temperature, and temperature of the water.

Accompanying Lesson Plan: Lesson 3.2: Finding Volume—The Water Displacement Method The chart shows that atomic size and mass for the first 20 elements in the periodic table. The size of the atoms and ...
