Water has a density of 1g/cm3. Describe an investigation that could test whether a material has a density less than, greater than, or equal to water and identify the independent and dependent variable in your investigation. Also, identify your hypothesis.

Answer:

You can test whether or not the object is more or less dense than what by having, “80mL” (as long as the amount of water is easy to read and doesn’t overflow). You take all the object you want to test for, slowly and carefully drop the object into the water. If the Object sinks it is more dese and if it floats it is less dense. To find the exact density of the tested objects look at how much water is being displaced in the container and subtract the amount of water from that to get volume. Then, (or before putting the object into water) weight the object to find its mass. Next you divide the mass in mL by the volume to get the exact density.
