This test is a culmination of a unit on density. The assessment tests students' knowledge on mass, volume, and density and how these concepts are all related. The test consists of many higher level questions and makes students apply their understanding of these topics and not simply memorize information. Students should be familiar with calculations and understand how to find the density of an irregular object.
For the performance portion of the test, I give my students a mystery object, and they must calculate its density and determine the material from which it's made by looking at a chart. Teachers will need to provide the materials necessary for the performance task such as a balance, graduated cylinder, water, etc.
I have made this test in Word to make editing easy, and an answer key is also included for easy grading. Thanks!!
