Change in Temperature - Exothermic Reaction
Alone, or as part of the intended unit on chemical reactions, this activity allows learners to experience an exothermic reaction. Here, learners add calcium chloride to a baking soda solution and watch the temperature rise! They will...
Curated OER
Physical and Chemical Changes
Students observe examples of physical changes that can take place between the three states of matter and develop common sense and intuition in distinguishing between chemical and physical changes. They observe diagrams on the board from...
