Science Lab - Weight Watching

Students today had to predict the weight of 3 objects: a plastic chip, a wooden block and a steel washer.  They had to put the objects in order from heaviest to lightest. Everyone predicted that the washer was heaviest but there was argument between the wood and the plastic. How could we prove which one was heavier? THE BALANCE BEAM! After clarifying the argument, students made their own prediction on the weight of certain objects and were able to prove or disprove their findings. 




                       
 
Students were able to correctly use a balance beam to accurately measure the objects using the standard unit grams.
