Target Level: Interpret and analyze data on the properties (e.g., color, texture, odor, and state of matter) of substances before and after chemical changes have occurred (e.g., burning sugar or burning steel wool, rust, effervescent tablets).
Precursor Level: Gather data on the properties (e.g., color, texture, odor, and state of matter) of substances before and after chemical changes have occurred (e.g., burning sugar or burning steel wool, rust, effervescent tablets).
Initial Level: Observe and identify examples of change (e.g. state of matter, color, temperature, and odor).
* Property - a quality or characteristic of something.
* Matter - the physical substance that everything is made of.
* Chemical change - a change in how the atoms of one or more substances are arranged. It leads to the formation of a new substance and is usually not reversible.
* Physical Change - a change to the physical properties of a substance, like a change in size.
* Gas - a state of matter that is not liquid or solid or a substance that has this form. It has no fixed shape or volume. Hydrogen and carbon dioxide are examples.
* Solid - a form of matter that is not a liquid or gas and that has a definite shape.
* Liquid - a form of matter that is not a solid or gas. It has a fixed volume but not a fixed shape.
