What's Up with Our Air?

The students will use modeling to understand inversions. Their models will evolve as they gather more information.

Plan and carry out investigations to identify substances based on patterns of their properties. Examples of substances could include powders, metals, minerals, and liquids. Examples of properties could include color, hardness, conductivity, solubility, and response to magnetic forces.

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.

Construct a scientific explanation based on evidence that shows that the uneven distribution of Earth’s mineral, energy, and groundwater resources is caused by geological processes.

Performance Expectations
Students will use models as they investigate the phenomenon of inversions. Their models will evolve as demonstrations are introduced.
