Science - Chemistry
Students will understand that in chemical reactions matter and energy change forms, but the amounts of matter and energy do not change.
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.
Students will use wooden atoms to model and balance a chemical reaction.
Student will observe a reaction between vinegar and baking soda and then design an experiment to test a variable affecting the reaction.
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.
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.
