Density Ranking Tasks - Questions

The Density Ranking Tasks Concept Builder is comprised of 45 questions. The questions are divided into 15 different Question Groups and spread across three distinctly different activities. Questions in the same group are rather similar to one another, involving the ranking of three different samples according to their density. The Concept Builder is coded to select at random a question from each group until a student is successful with that group of questions.

There are activities in the Concept Builder. Those three activities can be described as follows:
 

• Particle Diagrams: Question Groups 1-6 ... Analyze particle diagrams for three samples of matter in order to rank them according to their density..
• Mass and Volume: Question Groups 7-9 ...Rank three samples of matter according to their density based upon information about their mass and volume values.
• Sink, Float and Displace: Question Groups 10-15 ... Make observations about density columns and density experiments in order to rank three samples of matter according to heir density..

The questions from each group are shown below. Teachers are encouraged to view the questions in order to judge which activities are most appropriate for their classes.
