Understanding Half–Life : Simulating the process of a radioactive material decaying according to the concept of a half-life. part of MnSTEP Activity Mini-collection
In this activity, students will learn the concept of half-life of a radioactive material. Students will create and be able to recognize a graph representing the half-life of an imaginary radioactive element.

Accuracy and Precision Lab (with measurement and density) part of MnSTEP Activity Mini-collection
In this lab exercise, students practice correctly using measurement tools, recording data, calculating density, using significant figures, and exploring the concepts of accuracy and precision.

Modeling Valence Electrons part of MnSTEP Activity Mini-collection
This activity is a guided practice and scaffolding activity in which the students learn how to configure electrons of elements and determine the number of valence electrons.

Exploring Freezing Point Depression using Freeze Pops part of MnSTEP Activity Mini-collection
This activity is a laboratory activity where students gather data relating quantities of salt to the freezing point of water/ice.

Observation of a Candle part of MnSTEP Activity Mini-collection
This is a lab experiment where students make detailed observations of a candle use them to infer the products of combustion of a candle.

Using Properties to Identify Ionic and Molecular Compounds part of MnSTEP Activity Mini-collection
An inquiry activity for students to test physical properties of several compounds to analyze data and determine if the compound is ionic or covalent. This is ideal for an introduction to ionic and molecular compound nomenclature.

Mass Spectrometry: Using a Game Format to Develop Logic Skills While Applying Fundamental Chemistry Knowledge to Determine Possible Chemical Formula Represented in Graphic Output From A Mass Spetrometer part of MnSTEP Activity Mini-collection
This activity is a series of game-like lessons that assist the student in developing the logic skills needed to read mass spectrometer output and formulate the identity of an unknown molecule. As students endeavor to identify the unknown they must apply fundamental chemistry knowledge including formula mass, isotopes, periodic table, relative abundance, interpreting graphs, organic chemistry, ionization, bonding rules, and structural formulas.

Mini-Lab: Investigating Gas Laws part of MnSTEP Activity Mini-collection
This activity is a mini-lab where students determine relationships between gas laws and temperature, pressure, and volume; particularly Charles and Boyle's Law.

The Disintegration of Polystyrene Lab part of MnSTEP Activity Mini-collection
This lab activity shows students the Law of Conservation of Matter and intermolecular forces by having them dissolve packing peanuts in acetone.

Properties of Cations: Flame Test Lab part of MnSTEP Activity Mini-collection
In this lab students will make qualitative observations of flame color, a property of metals, to identify unknown metals in salt compounds.
