If an object floats, you can hold it under water to measure its volume.  \n􀁸 Use the scale and the volume of water displaced to calculate the density of the mystery objects.  \n􀁸 Use the table to determine the identity of the mystery objects.  \n􀁸 If you are doing a lecture demonstration, set your screen resolution to 1024x768 so the simulation will fill the screen and be seen easily.  \nImportant modeling notes / simplifications:  \n􀁸 For named objects in the drop-down menu, mass changes volume to keep density constant; for \"My Block\", mass changes density.  \n􀁸 The color of an object in one mode does not imply the same density in other modes; we did this to challenge students to use other characteristics to understand density.  \n􀁸 In the \"Same Mass\" mode, the density of the blue block is the same as that of water.  \n􀁸 We purposely left out the density of water on the slider, since we saw that it caused students to engage more with the sim.  \nInsights into student use / thinking:  \n􀁸 Students do not need to be told to put the block in the water; it is often their first move.  \n􀁸 Students who do not already know the density of water are able to figure it out by playing with the sim.  \n􀁸 Some students notice that when objects float, they displace their mass, but when objects sink, they displace their volume.  \n􀁸 Students learn that density is what determines whether an object sinks or floats.  \n􀁸 Students are confused by the behavior of the blue block in the “Same Mass” mode; later they discover the block has the density of water.  \n􀁸 Most students do not notice the table in the “Mystery” mode.  \nSuggestions for sim use:  \n􀁸 For tips on using PhET sims with your students, see: Guidelines for Inquiry Contributions and Using PhET Sims.  \n􀁸 The simulations have been used successfully with homework, lectures, in-class activities, or lab activities. Use them for introduction to concepts, learning new concepts, reinforcement of concepts, as visual aids for interactive demonstrations, or with in-class clicker questions.
