Thermometric Titration Involving Dataloggers
In this thermometric titration learning exercise, students determine the concentrations of hydrochloric acid and ethanoic acid using a titration where they measure the temperature of the solution as they titrate. The equivalence point is...
Curated OER
Reactivity Series Questions
In this reactions worksheet, high schoolers read about two types of reactions that take place between metals: displacement and competition. Then students answer 2 problems.

Chemical Reactions and Engineering Design
Construction leads to habitat loss and local wildlife suffers. Scholars must build a reptile egg incubation device that meets many constraints. Various experiments help them discover the chemical reaction needed to reach the proper...
Normal Community High School
Chemical Equations
Viewers learn how to identify the substances in a chemical reaction, how to balance it, and the different types of chemical reactions by watching a presentation that also includes a review of monomers and polymers. The presentation ends...
Curated OER
Temperature
Several slides compare different temperature scales. Thermal expansion, heat transfer, and Maxwell speed distribution are also explored. The last two slides seem unrelated to the topic of heat, but are easily left out of this otherwise...

Transition State Theory
In this transition state theory worksheet, students read about chemical reactions and the theory for how chemical reactions proceed. They answer questions about the activated complex, the activation energy and the collision theory all...
Curated OER
Being Spontaneous
In this spontaneous reactions worksheet, students read about entropy, enthalpy and Gibbs free energy. They complete a table with reaction conditions and determine if the reaction is spontaneous or not. They solve three problems about...
Curated OER
Reaction Reasoning
Third graders experiment with chemical reactions and examine what happens to the atoms when different reactions occur. In this matter lesson students divide into groups and complete a lab experiment.
Curated OER
Oxidation and Combustion: Chemical Reactions in Fire
Students study oxidation and define vocabulary pertinent to it. In this oxidation lesson students make predictions and create experiments
Curated OER
Super Glue Fuming of Latent Fingerprints
Pupils explore latent fingerprinting. They observe a supervised demonstration of the process that real-life crime scene investigators sometimes use to identify latent fingerprints. In addition, they brainstorm ways to improve the process...
Curated OER
Interpreting Reaction Coordinates
For this reaction coordinates worksheet, students are given a diagram of the reaction coordinate for a reversible catalyzed and uncatalyzed reaction. Students answer eighteen questions related to the diagram.
Curated OER
Reaction Mechanisms
In this reactions worksheet, students give the equation for the overall reaction, identifying the catalyst in the equation. Students create graphs and write out the rate determining step. This worksheet has 4 graphs, 2 short answers, and...
