1P8,
In the practical worksheet, we were supposed to a measure the density of and irregular object. In this Lab Lesson, we measured 5 glass marbles.
Formula of Density:
Mass / Volume = Density
Firstly, we were to find the Mass of the Marbles. We measured the weight of an empty water bottle then with the marbles in it. Then we subtracted the weights to find the mass. Simple Maths! Then we tried to find the diameter then the radius. We then found the volume by the simple Maths formula again. From there, we found out the density, half of our job DONE!
1P9,
In 1P9, we were to measure the density of irregular object.This time we were to measure a glass stopper. The glass stopper is shaped like a siren... Not sure how to describe it but it looks like |=>(weird thing). It was more easy to measure this then the regular object, we we needed to do was to find the mass, same way as the regular object, then the volume by putting the object into a measuring cylinder filled with water and then subtract. Then it's good ol' formula again.
This lab lesson was quite normal as I did it once for my primary school life, but we did not really get hands-on.
