Classroom Resources: Molecules & Bonding
51 – 55 of 55 Classroom Resources
-
Separating Mixtures, Density, Physical Change, Chemical Change, Mixtures, Intermolecular Forces, Intermolecular Forces | Middle School
Lab: Clean it Up!
In this lab, students will consider and utilize various separation techniques to purify and reclaim used motor oil.
-
Mixtures, Physical Properties, Molecular Structure, Mixtures | Elementary School, Middle School, High School
Demonstration: Analyzing Mixtures
In this demonstration, the teacher will create a sequence of mixtures in a single test tube. Water, oil, food coloring and soap will be used in this demonstration to introduce the concepts of heterogeneous and homogeneous solutions as well as the idea of miscibility. Students will also have the opportunity to analyze the properties, such as surface tension of each component used.
-
Percent Composition, Scientific Method, Introduction, Percent Composition | Middle School
Lab: Mass Percent
In this lesson, students will develop a theory of how to calculate percent composition.
-
Ionic Bonding, Naming Compounds, Precipitate, Ions, Molecular Formula | Middle School
Activity: Bond with a Classmate
In this activity, students are assigned an ion and form bonds with their classmates, recording the formula and name of the compound they created.
-
Molecular Formula, Ionic Bonding, Covalent Bonding, Molecular Geometry, Naming Compounds, Lewis Structures, Periodic Table, Valence Electrons, Lewis Dot Diagrams, Ions, Subatomic Particles | High School, Middle School
Simulation: Ionic & Covalent Bonding
In the September 2016 simulation, students investigate both ionic and covalent bonding. Students will have the opportunity to interact with many possible combinations of atoms and will be tasked with determining the type of bond and the number of atom needed to form each. Students will become familiar with the molecular formula, as well as the naming system for each type of bond and geometric shape, when applicable.
