Build a Fuel Cell
Discover the connection between redox reactions and fuel cells. Collaborative groups build a Hoffmann Apparatus that demonstrates the electrolysis of water and then convert their models into a fuel cell. They use their fuel cells to...
Curated OER
Decomposition vs. Synthesis Reaction
Young scholars define the term chemical reaction, identify the reactants and products in a chemical reaction, distinguish between decomposition and synthesis reactions and construct reactions using food items.
Curated OER
How Are The Properties of Covalent Compounds Influenced By Chemical Bonding?
Students work together to observe the bond lengths of single, double and triple bonds. They make their own predictions about the strength of the bonds and chemical reactions. They answer discussion questions to complete the lesson.

Are All Plants Created Equal?
Photosynthesis requires energy and produces food, and cellular respiration produces energy and requires food. An interesting lesson analyzes the factors that affect the rates of photosynthesis and respiration. Classes spend one day...
Curated OER
Iron Filings
Students conduct an experiment in which a solution of copper(II) sulfate is added to iron filings. They write and balance the equation for the reaction that occurs and calculate the amount of iron that reacted and the percent yield of...
Cornell University
What Is Rust?
Why do metals rust differently? Scholars experiment with metal combinations in a hands-on activity. They create unique environments with different metals and compare the rate and amount of rust for each.

Forms of Energy
The amount of energy Americans use doubles every 20 years. The first lesson in a 10-part series teaches scholars about different forms of energy. They rotate through five stations with hands-on activities or experiments at each in order...
Curated OER
Observation and Stimulation of bioluminescence and chemiluminescence
Students are introduced to chemical reactions, reaction rates, chemiluminescence, fluorescence and bioluminescence. They use glow sticks are used to demonstrate the effect of temperature on the rates of chemical reactions. Pupils recall...
Curated OER
Crazy Chemistry Lesson Plan
Young scholars study water molecules, cohesion and surface tension. In this molecule cohesion lesson students create chemical reactions that cause a balloon to inflate and another one that results in soap suds.
Curated OER
Chemical Equilibrium
Students explore Le Chatelier's Principle. In this lesson about chemical equilibrium, students do an experiment with several different activities . Students observe as they do the experiments and understand the outcome. Students become...
