Chemistry


What?!? Chemistry? At The Physics Classroom?

Yes. Why not? We're not breaking any laws ... it's perfectly legal. You might say we're dabbling a bit ... sort of like an experiment. The Concept Builders you see below are  interactive questioning modules that present learners with carefully crafted questions that target various aspects of a concept. If you're a frequent visitor to our website, you likely have used some of our Physics Concept Builders. Each Concept Builder focuses the learner's attention upon a discrete learning outcome. Questions target that outcome from a variety of angles using multiple difficulty levels or varying activities. Learners ponder the given information and answer questions in the hopes of earning Stars and Trophies. These Stars (for answering questions) and Trophies (for completing levels or activities) are displayed on the screen, allowing a teacher to track student progress. If you're a chemistry teacher visiting our website for the first time, then welcome! We invite you to give one of our Chemistry Concept Builders a try and let us know what you think. 


Significant Digits and Measurement
 
Learning Goal: To understand the concept of significant digits and to use such understanding to make and process such measurements made from lab equipment.



Particles .. Words .. Formulas
 
Learning Goal: To associate the particle representation of a sample of matter with the proper verbal description and formulas.



Isotopes
 
Learning Goal: To demonstrate understanding of the composition of an atom by constructing the isotopic symbol from information regarding the number of protons, neutrons, and electrons.



Names to Formulas 1
 
Learning Goal: To use an understanding of formula writing to identify incorrectly written formulas.  (Includes binary ionic compounds only.)



Names to Formulas 2
 
Learning Goal: To use an understanding of formula writing to identify incorrectly written formulas.  (Includes binary molecular compounds, binary ionic compounds, and compounds containing polyatomic ions.)



Balancing Chemical Equations
 
Learning Goal: To be able to use coefficients and an atom count to balance a chemical equation. 




Precipitation Reactions
 
Learning Goal: To predict the precipitate that is produced when two aqueous solutions of ionic compounds are mixed and to represent the precipitation reaction by a net ionic equation.



Stoichiometry: Relationships
 
Learning Goal: To use the coefficients of a balanced chemical equation and the molar masses of reactants and products to relate the quantities of reactants and products involved in a reaction.




Complete Electron Configurations
 
Learning Goal: To identify the complete electron configuration for a neutral atom or of an ion of any given element.




Periodic Trends
 
Learning Goal: To order elements based on the values of periodic properties such as atomic radius, ionization energy, and electronegativity.



Lewis Structures
 
Learning Goal:  To identify correct and incorrect Lewis electron dot structures when given the formulas of molecular compounds.



Which One Doesn't Belong? - Energy and Chemical Reactions
 
Learning Goal:  To interpret various representations of a thermochemical reaction and to identify which one is not consistent with the others.



Pressure and Temperature
 
Learning Goal:  To use an understanding of the pressure-temperature relationship in order to predict how the value of pressure changes with changing temperature.



Pressure and Volume
 
Learning Goal:  To use an understanding of the pressure-volume relationship in order to predict how the pressure of a gas changes with varying volume.



Dissociation
 
Learning Goal:  To be able to write the equation for the dissociation of an ionic compound in water and to use the equation to determine ion concentrations if given the concentration of the ionic compound. 




Bronsted-Lowry Model of Acids and Bases
 
Learning Goal:  To use the Bronsted-Lowry model to determine the products of the dissociation of an acid or a base when dissolved in water.



Equilibrium Constant Expression
 
Learning Goal:  To use the Law of Mass Action in order to identify the equilibrium constant expression for a given chemical equation.






We started adding Chemistry Concept Builders in September, 2018. As of this writing (early June, 2019), we have 17 Chemistry Concept Builders. We plan to add more to the collection during the Summer of 2019 and over the course of the 2019-20 school year. So stop back by again and find something new.
