Curated OER
Endothermic or Exothermic That Is the Question
Students conduct an experiment to determine what happens to heat energy during a chemical reaction. They examine an endothermic reaction by observing a chemical reactions.
Curated OER
Heat Loss and Gain in Physical Changes and Chemical Reactions
Students compare and contrast exothermic and endothermic reactions. In this chemistry lesson, students perform experiments to determine whether heat was released or absorbed in a reaction. They share their observations in class.
Curated OER
Chemical Reactions
In this reactions worksheet, students state the differences between a coefficient and subscript and an exothermic and endothermic reaction. Students review the different types of reactions. This worksheet has 13 short answer questions.
Curated OER
Reptiles and Birds
In this classification worksheet, students review 5 vocabulary terms that describe reptiles or birds. These 5 terms are placed into a crossword puzzle.
Curated OER
Einstein's BIg Idea
Students discuss what the m in E=mc2 represent. They relate that mass in a chemical reaction is always conserved. Students convey that atoms rearrange themselves in chemical reactions to form different molecules and compounds.
