Listed
below are the skills you will need to use during this lab.
If you are unsure of any of them ask your instructor for
assistance before completing the activity.
_____ a) How to use a balance
_____ b) How to read a graduated cylinder
_____ c) Where to find the density formula
_____ d) How to use the density formula mathematically
_____ e) How to write up a lab report
2)
Procedure/Information collection:
Procedure for determining the density of a regular shaped
object:
1) Select the regular shaped object
2) Using a triple beam balance, record the mass of the object
to the nearest tenth of a gram. (Be sure to do this with
a dry object)
3) Using a metric ruler, measure the length, width, and
height of the object
4) Write down the formula for calculating the density of
the object (refer to the Earth Science Reference tables)
5) Substitute the values you measured into the formula and
calculate the density
6) Calculate the density using the density formula. Record
the answer as cm3.
Procedure
for determining the density of an irregular shaped object:
1) Select the irregular shaped object
2) Using a triple beam balance record the mass of the object
to the nearest tenth of a gram. (Be sure to do this with
a dry object)
3) Place water into the graduated cylinder and record the
level
4) Without splashing any water, place the irregular shaped
object into the graduated cylinder so that it is completely
submerged in the water.
