Classroom Resources: Molecules & Bonding
26 – 32 of 32 Classroom Resources
Observations, Physical Properties, Mixtures, Solubility, Intermolecular Forces, Polarity, Identifying an Unknown, Intermolecular Forces, Chemical Properties, Intramolecular Forces, Mixtures | High School
In this lesson, students determine whether unknown substances are polar, nonpolar, or ionic by testing their solubilities.
Observations, Separating Mixtures, Physical Properties, Intermolecular Forces, Polarity, Distillation, Cracking, Balancing Equations, Intermolecular Forces, Boiling Point | High School
In this lesson, students will be introduced to simple distillation while expanding their knowledge of intermolecular forces. Once a simple distillation has been accomplished in the lab, students will then research the various products of fractional distillation of crude oil and report on one of those products.
Physical Change, Intermolecular Forces, Polarity, Physical Change, Intermolecular Forces, Matter | Middle School
In this lesson, students will investigate the properties of magic sand and learn about the concept of hydrophobic and hydrophilic molecules. It also introduced students to the field of nanotechnology.
Observations, Physical Properties, Mixtures, Intermolecular Forces, Polarity, Intermolecular Forces, Mixtures | High School, Elementary School, Middle School
In this lab, students mix polar and nonpolar substances and then add various emulsifiers to encourage the mixing of the two substances. They use ingredients in salad dressing to relate science to real life scenarios.
Physical Properties, Mixtures, Solubility, Melting Point, Intermolecular Forces, Freezing Point, Polarity, Molecular Structure, Solute & Solvent, Intermolecular Forces, Boiling Point, Intramolecular Forces, Graphing, Mixtures, Lewis Structures | High School
In this lesson, students investigate how intermolecular forces effect physical properties by investigating substances’ melting points as well as solubility.
Separating Mixtures, Density, Mixtures, Chemical Change, Intermolecular Forces, Physical Change, Intermolecular Forces | Middle School
In this lab, students will consider and utilize various separation techniques to purify and reclaim used motor oil.
Physical Change, Intermolecular Forces, Polarity, Physical Change, Molecular Motion, Molecular Motion, Intermolecular Forces
In the November 2014 issue, students explore the different attractive foreces between pairs of molecules by dragging the "star" image. In the accompanying activity, students investigate different types of intermolecular forces (London dispersion and dipole-dipole). In the analysis that follows the investigation, they relate IMFs (including hydrogen bonding) to physical properties (boiling point and solubility).
