I'm not looking into anyone giving me any answers here, but I just want to gather some ideas for a lab that requires me to calculate the volume and wieght (therefore, finding the density) of a grain of salt and sand. I've thought about the idea of counting out 100 grains and then weighing them, then dividing it by 100 for weight. And to use a water displacement method to find the volume, again using 100 grains of salt. Does anyone have any other possible ideas? Any advice, input, and thoughts, would we well recieved. Thanks, Jason P.S. - My teacher says that is a lab that will not work effectively. The teacher is more interested in finding out how I do the lab, not my lab results.
