Two groups were tasked to measure the mass of the metal objects given by their teacher. Rachel’s group has the following data fo
Studentka2010 [4]

The measurement of Rachel’s group is precise but not accurate while the measurement of Ashley’s group is accurate but not precise.

Precision has to do with how close together the values obtained from a scientific measurement is. If we take a look at the values obtained by  Rachel’s group, we will notice that the values are exactly 1.00 g apart. This means that the values are precise.

However, these values a far from the actual value which is 100.00 g therefore the measurement of Rachel’s group is precise but not accurate.

On the other hand, the values obtained by Ashley’s group are; 99.5 g, 100.1 g, and 100.5 g. These values are very close to the actual value which is 100.00 g  hence they are accurate.

The values obtained by Ashley’s group do not have consistent intervals therefore, they are not precise.

Why would it be difficult to sift the iron fillings from the sand
slamgirl [31]

Explanation:

Sand and iron fillings have the same size of particles.

It would be difficult to use a mesh to separate them. Also, sometimes , the iron filing clings well to the surface of the sand particles.

The best way to separate them is to use a bar magnet. The magnetic properties of the iron fillings will get it attracted to the bar magnet leaving the sand particles behind.
