In our class, Kru Gary taught us about density. We measure the mass regularly. We measure the volume using the Archimedes's way of doing this by measure the volume of the water that can fit a rock inside it and then we put the rock inside of it until it reached some point. After that, we measure the excess using the graduated cylinder and the other part using the beaker. Then, you calculate the difference of the with rock volume and without rock volume. This way of measuring a volume is called Measuring Volume by Displacement. Finally, you calculate the density by divide the mass by the volume and the result is in the chart up there. 🔝
