Curated OER
Paper Chromatography
Small groups of students perform paper chromatography to separate food dyes into their component colors. Students perform the experiment and collect, organize, and represent their data to form an explanation of their outcomes. Students...
Curated OER
The Flame and the Atom:
Students investigate the structure of atoms. Students read information about the Rutherford model, the Bohr model, and the Quantum Mechanical model examining each for its scientific validity. They watch a PowerPoint presentation of alpha...

Observing the Effect of a Change in Conditions on a System at Equilibrium by Applying Le Chatelier's Principle
Students describe the Le Chatelier Principle. They participate in an experiment in which they observe the changes in an equilibrium system. They answer discussion questions to end the lesson.
Curated OER
Learning how to balance equations
Students play Chembalancer game and balance equations using the trial and error method.
Curated OER
Crystallization
Eighth graders analyze physical change in mass. In this chemistry lesson, 8th graders describe, measure and calculate the amount of physical change occurring in mass before and after the change. Students should be familiar with elements,...

The Blue Bottle: An Example of Teacher-Guided Inquiry
High schoolers observe a demonstration in which a bottle containing a colorless solution is mixed, turns blue, then becomes colorless again. They record observations, form and discuss hypotheses, and draw a conclusion based on the evidence.
Curated OER
You say Avocado, I say Avogadro
Students convert mole to mass to particles and vice versa. In this chemistry lesson, students discuss the importance of Avogadro's number. They apply what they have learned in a team competition.
Curated OER
Code Makers - Electron Configuration, Aufbau Principle
Learners write the electron configuration of elements using the Aufbau principle. In this chemistry lesson, students build their own key that demonstrates the principle.
Curated OER
Synthesizing Pigment and Dyeing Cloth
Students create a synthetic dye and oxidize the dye and record the effects.
Curated OER
Understanding of the Structure of an Amino Group
Learners review the characteristics of acids and bases. They examine the structure of an amino group and compare amines to ammonia. They work together to develop the concent of polymerization.
Curated OER
Acid and Base Testing
Young scholars study descriptions of indicators and the way they are used to identify acids and bases. They use this information to determine if unknown solutions are acids or bases.
Curated OER
Where My Peeps At?
Students conduct a series of activity that demonstrates Charles' and Boyle's Law. In this chemistry lesson, students determine the relationship among pressure, volume and temperature. They solve problems using mathematical equation.
