Student precision using glass pipettes part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
In this beginning of the year lab, students will investigate the concept of precision, graphing and collecting class data. By doing the lab, collecting data and constructing a class data table and graphing the results students will be able to understand the concept of precision. The students will write a lab report that describe their findings.

Flame Test part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
In this physical science experiment, students investigate the release of energy by observing the color of light produced when salts are heated in the flame of a burner. Students will identify the metal ion of the substance by the color emitted.
