5Cool Reaction! The Reaction of

Baking Soda and Vinegar

Have you ever mixed vinegar and baking soda? Its fun to watch, but did you know that

the reaction between the two is actually a chemical reaction that produces gas and

changes temperature, too? The gas it produces is carbon dioxide, C !, and the

temperature changes" #oes the temperature go up or down? $e will soon find out%

BECT"VES

In this activity, you will

&roduce a reaction between baking soda and vinegar" 'easure the changing temperature of a reaction"
