Density lab: log on the following site: Choose any two samples # to conduct the lab to calcualte the density of the two minerals you choose. copy the following url link and paste into your browser to go to the website. http://academic.brooklyn.cuny.edu/geology/leveson/core/graphics/density/density_sim3.html
Read and follow the instructions. Use the density formula density= mass (m)/volume (v) From the experiments, you need to obtain the mass using triple valance and the volume using the graduate sylinder.
click the imerse the mineral button: Voume of mineral is the volume difference between the volumes before and after imersing the mineral. then, for mass, click the weigh the mineral button: How to use triple beam balance = top beam is 100s, middle beam shows10s, and last beam shows 1s and one decimal (eg. 112.3g)
