Lesson Plans  
Standard 4
Students will understand that in chemical reactions matter and energy change forms, but the amounts of matter and energy do not change.
Objective 1
Identify evidence of chemical reactions and demonstrate how chemical equations are used to describe them.
  • A Modern Day Con Game
    Students read a description of an attempted forgery that was solved using a silver chloride precipitation reaction. They will write the chemical equations for the reactions and make an illustration for the reading selection.
  • Balancing Act
    Students will use wooden atoms to model and balance a chemical reaction.
  • Bang!
    Student will observe a reaction between vinegar and baking soda and then design an experiment to test a variable affecting the reaction.
  • Cake Lab
    Students will bake a cake, brownies, cookies etc. This will be used to introduce chemical reactions and writing balanced equations.
  • Chemical Reactions and Equations
    With this experiment, students will iIdentify evidence of chemical reactions and demonstrate how chemical equations are used to describe them.
  • How Do You Know When a Chemical Reaction Has Occurred?
    With this simple Inquiry lab students will be introduced to chemical reactions.
  • Incomplete Combustion: Chemistry of Air Pollution
    Students will design and carry out a class experiment comparing the emissions of a diesel and gasoline car then use chemical equations and molar proportions to see why larger molecules are more difficult to burn completely.
  • Observing Reactions in Lightsticks
    Students will use lightsticks to understand the chemical reaction that takes place when it is snapped.
  • Reactions!
    Students use colored marshmallows (representing atoms) to construct compounds and arrange them into a balanced chemical equation.
  • Recognizing Chemical Reactions
    Students will add 4 chemicals to a beaker and observe the changes that take place. They will classify them as physical or chemical changes.
  • Types of Chemical Reactions Jigsaw
    Students will perform chemical reactions for the class to observe evidence of reactions and write equations to describe the reaction.
