Curated OER
Did a Chemical Reaction "Really" Occur?
Learners perform several different experiments to observe signs of chemical reactions and determine if reaction has occurred, use search engine to find Internet sites pertaining to chemical reactions, and write up brief summary of site.
Curated OER
Matter
Eighth graders explore chemical reactions and their products. They define a chemical reaction and describe the characteristics of a chemical reaction. Students classify chemical reactions.
Curated OER
Chemical Changes
Eighth graders observe two types of interactions in a sealed plastic bag. One bag contains baking soda and water, and the other baking soda and vinegar. They determine what evidence indicates that a chemical change is occurring.
