Is Your Valley a Density Tank?


Students will use a density tank to visualize an inversion. Connections will be made between the valleys in Utah and the winter cold air pool phenomenon.

Objectives

Ask questions to carry out investigations to identify substances based on patterns of their properties. Emphasize using properties to identify substances. Examples of properties could include color, hardness, conductivity, solubility, or a response to magnetic forces. Examples of substances could include powders, metals, minerals, or liquids.

Develop a model to predict the effect of heat energy on states of matter and density. Emphasize the arrangement of particles in states of matter (solid, liquid, or gas) and during phase changes (melting, freezing, condensing, and evaporating).

Obtain information about various properties of matter, evaluate how different materials’ properties allow them to be used for particular functions in society and communicate your findings. Emphasize general properties of matter. Examples could include color, density, malleability, hardness, malleability, odor, ability to rust, solubility, state, or the ability to react with water.

Performance Expectations
Students ask questions and analyze patterns found in the event of inversion and what happens in a density tank.
