Atoms and Molecules part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
Both of these lessons are classroom activities that require students to build models that display understanding of atoms and molecules. One lesson is structured while the other is guided.

Modeling Valence Electrons part of MnSTEP Teaching Activity Collection: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.

Properties of Cations: Flame Test Lab part of MnSTEP Teaching Activity Collection: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.

Tic Tac Toe - Pick 3 in a Row Atomic Model Assignment part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
This activity is a summary/assessment assignment which allows for differentiation and student choice. Students are assessed in their knowledge of the atomic model and the arrangement of elements on the periodic table.

Building 3D Models of Atoms part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
This activity is a hands-on building of atoms of elements 1-20.

Making Bath Salts for Mother's Day, a Primary Chemistry Lesson part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
This activity is a guided discovery where students make chemical mixtures using sodium, learn about the Periodic Table, view salt under a microscope, and have a final result of bath salts for the bathtub

Chlorine Chemistry: A Building Block of Matter part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
This activity provides a demonstration and lab exploration of one of the main "building blocks" of the periodic table of elements: chlorine. During the lab, students compare physical and chemical properties of chlorine compounds.

"Chemory" the game part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
Matching game, including matching common ionic charges and ions and the compounds they form and naming of greek prefixes for covalent molecules.

Rutherford's enlarged: A content-embedded activity to teach about nature of science part of Process of Science:Examples
This activity can be used to help middle and secondary school students develop more informed understandings of some important aspects of nature of science in the context of teaching them about Rutherford's experiments and atomic structure.
