This activity is an introduction to exothermic and endothermic reactions. Students investigate the reaction between baking soda and vinegar and measure the temperature as the substances react. As they add baking soda to the vinegar, the temperature goes down. Through an introductory reading students learn about exothermic and endothermic reactions and write a scientific argument with Claim, Evidence, and Reasoning to explain whether the reaction absorbs or releases energy.
1 beaker or cup
Tray or pan to set the cups on – just in case the reaction fizzes over the top
This comes from my “Quick and Cl-Ev-R” series. Each activity is designed for students to practice writing scientific arguments with Claim, Evidence, and Reasoning based on real world data and experiences. Each activity includes a quick hands on activity or demonstration, data collection, and corresponding reading focusing on the scientific concepts presented in the activity.
This activity is part of my C-E-R Physical Science Bundle
