Sinking, Floating, and Hanging

In the Sinking, Floating, and Hanging Concept Builder, learners will explore the details of the factors that cause an object to sink to the bottom of its container, to float on the top of the water's surface, or to hang amid the water in neutral buoyancy. There are 72 total questions that are organized into 18 different Question Groups and spread across three Activities. The three activities include Case Studies 1, Case Studies 2, and Force Analysis. Activity 1 - Case Studies 1 presents two situations in which learners must compare in terms of Fgrav and Fbuoyant and determine whether the objects sink, float, or hang. In Activity 2 - Case Studies 2, learners are presented two situations and must compare their Fgrav, Fbuoyant, and average densities. And in Activity 3 - Ranking Tasks, learners must calculate Fgrav and Fbuoyant values, identify the accurate free-body diagram, and predict whether the object will sink, float, or hang. Question-specific help is provided for each of the 18 situations. Use of this Concept Builder with our Task Tracker system allows teachers to track student progress.
