MS-PS1-1: Develop models to describe the atomic composition of simple molecules and extended structures.
This resources requires students to practice their knowledge of molecule building using basic bonding rules for covalent bonding where atoms share valance electrons to be able to achieve full valance layers of electrons. They bond until all atoms in the molecule/compound have satisfied this basic need/requirement.
This exercise/simulation is for students to practice these skills by making 11 covalent compounds listed in the simulation provided by glencoe virtual labs. The simulation will provide info to help as well as tell the student whether their created model for each is correct or incorrect. Students should have already been instructed on basic Bohr models of electron orbitals, what valance electrons are, how to identify how many valance electrons atoms of elements in the periodic table have (not including transition metals), and how to determine how many bonds each atom type will be able to/need to form prior to doing this simulation as otherwise students will be guessing with no reasoning guide to what they are doing.
Computer with internet & browser with ability to run flash
If using google chrome or chromebooks just have student click on the puzzle piece that shows up when opening the simulation/activity and select "allow". This will allow them to utilize the simulation by running flash through google chrome.
