How can two objects with the same appearance have different densities? In the activity kids construct density bundles by wrapping small objects in clay. Then they submerge them to find their volume and weigh them to find their weight before calculating density. This lab provides experience with measuring (weight and volume); using equipment (graduated cylinders and scales). There's also a focus on performing multiple trials. This is a traditional lab with a fun twist. 

 

Use this to learn and reinforce answers to questions such as:

❑  What is density a measure of?

❑  How can water displacement be used to measure volume?

❑  What do you need to know to calculate density?

 

Once students complete this activity, they can capture their observations using the included Lab Notes or probing questions included in the instructions.
