Micro-Magic With Sticky Ions
High schoolers view a video about the formation of precipitates. They complete a worksheet that asks them to identify what makes a compound form and what holds it together.
Curated OER
Exploring With Photograms
Students observe the interaction between energy absorbed, reflected or transmitted through an object in a photochemical process with a classroom demonstration.
Curated OER
Heat Transfer and Pollution
Students perform computer simulations on air dispersion. In this chemistry lesson, students calculate energy transfer based on specific heat and temperature change. They explain the causes of smog.
Curated OER
Thermometric Titration of an Unknown Acid
Students determine the number of ionizable hydrogen's in an unknown acid and determine the equivalent weight of an unknown acid. They determine the enthalpy change for the ionization of an unknown acid.
Curated OER
How Do I Get a Pure Sample of the Molecules I Make?
Students initially engage in online research and consult print materials to identify a compound to produce. Once a selection has been made, individually, students conduct lab experiments to isolate substances. The end product is a...
