Mystery Powders
Fifth graders evaluate the physical properties of 5 powders. Each powder is subject to different conditions. They describe each observation as with a chemical change or a physical change.
Curated OER
Chemical Reactions
For this chemical reactions worksheet, students rearrange the definitions to match the type of reaction and find an example of each reaction. They write the word equation for it and write the type of reaction for three given word equations.
Curated OER
Chemical Changes or Reactions
In this chemical changes worksheet, students create a concept map for chemical changes or reactions. They indicate the definition, the description, they give examples and they give non-examples in a graphic organizer.
Curated OER
Chemical Changes
Second graders investigate chemical changes and reactions and will identify four characteristics that indicate a chemical change. In this chemical change lesson plan, 2nd graders perform experiments that promote chemical changes. They...
Curated OER
Redox
In this redox learning exercise, students determine the oxidation numbers of each element for the given chemical formulas. Students write out the reactions for each example given. Students identify what part of the chemical equation is...

General Chemistry I
For this chemistry worksheet, students balance each of the reactions presented using the periodic table to help. Then they predict the products of the reactions and write the net ionic equation. Students also write the empirical formulas...
Curated OER
Ziplock Chemistry
Pupils participate in an experiment in which the substances are sealed in a plastic bag. Watching the experiment, they determine why the chemical reaction is taking place and calculate the temperature change. To end the lesson, they...
Curated OER
Chemical or Physical?
Fourth graders make observations of the reactions that happens between calcium carbonate and various liquids. During the experiment the students determine if there is a chemical change, a physical reaction, or no reaction when they mix...
Curated OER
Thermochemistry
Students begin familiarizing themselves with the concept of energy, systems and state functions. They are introduced to the following concepts: Conservation of Energy, Systems, Heat, Entropy, Enthalpy, and Gibbs Free Energy.
