Experiment title:____________________________________________________
This experiment will test the hypothesis that _______________________________________________________
regular object and irregular object can have different method to measure
____________________________________________________________________________________________
volume
____________________________________________________________________________________________
I predict that _________________________________________________________________________________
For____________________________________________________________________________________________
a regular-shaped solid the volume can be found by measuring its dimensions
and the mass is determined by weighing. For an irregularly____________________________________________________________________________________________
shaped solid, the volume is found by immersion in a liquid.
because_____________________________________________________________________________________
for a regular object the volume can be calculated using
____________________________________________________________________________________________
simple formula, while irregular cannot

Method
 Measure the mass of the
_______________________________________________
solid
material m on a top-pan balance
_______________________________________________
 Fill the measuring cylinder with a known volume of water V1
_______________________________________________ _______________________________________________
 Shack the solid material very well.
_______________________________________________ _______________________________________________
 Immerse the solid in the cylinder.
_______________________________________________ _______________________________________________
 Measure the new volume V2
_______________________________________________
_______________________________________________
 Calculate the solid volume as:
_______________________________________________
_______________________________________________
 V = V2 – V1
_______________________________________________
_______________________________________________
 Calculate the density as: Density
= m/V

Conclusion
I have found that____________________________________________________________________________________
regular object and irregular object can have different method to measure volume
__________________________________________________________________________________________________
This is because______________________________________________________________________________________
for a regular object the volume can be calculated using simple formula, while
__________________________________________________________________________________________________
irregular cannot
__________________________________________________________________________________________________
Evaluation
I trust my conclusion because:_________________________________________________________________________
For a regular-shaped solid the volume can be found by measuring its dimensions
__________________________________________________________________________________________________
and the mass is determined by weighing. For an irregularlyshaped solid, the volume is found by immersion in a liquid.

__________________________________________________________________________________________________
weak, only one trial so less accurate
Strengths of the method:_____________________________________________________________________________
__________________________________________________________________________________________________
__________________________________________________________________________________________________
__________________________________________________________________________________________________
Sources of error
wrong volume of object
no change when dive the
object
Improvements to the method
look from the meniscus of the liquid
use thin string/wire
use sensitive cylinder
Student did not look from the meniscus of the liquid;
Causes of anomalies:_________________________________________________________________________________
__________________________________________________________________________________________________
String/wire used may be thick;
__________________________________________________________________________________________________
__________________________________________________________________________________________________
Cylinder may not be sensitive

Targets to improve this piece of work:
_____________________________________________
take longer time to plan before
do the experiment
