Objectives
- Students will measure and analyze temperature changes during chemical reactions between solids and water.
- Students will develop a plan to produce and test a chemical reaction that results in a significant temperature decrease.
Vocabulary
- cold pack
- chemical reaction
- endothermic
- exothermic
- temperature
- solution
About the Lesson
In this lesson, students will use a temperature probe to analyze the temperature change in a solution.
As a result, students will:
- Measure the temperature decrease when various solids are dissolved in water.
- Analyze data to produce and test a chemical combination that would result in the best cold pack.
