Change in Temperature - Endothermic Reaction
Now that learners have been exposed to chemical changes, they learn that some take in heat and therefore, decrease in temperature. The same reaction that they have been investigating between baking soda and vinegar is revisited,...
Beyond Benign
The Heat Is On
Explore an exothermic reaction with a quick lab investigation. The activity builds on the previous lessons by examining an ingredient in many shampoos. Scholars record temperature data as sodium hydroxide and water interact.
