What a fun and creative way to incorporate science into one of the upcoming holidays! I really like how the worksheet that accompanies the experiment requires students to form a hypothesis, make observations, and develop a conclusion. This experiment is very versatile in that it can be used for a variety of grades – I think all students kindergarten to sixth grade would have fun with this! Thank you for sharing such a hands-on way to learn about chemical reactions! 🙂
Thank you!I loved it!I loved it thank you!
Where do you get blue baking soda? I figure I can add food coloring to both soda and vinegar but not sure. Thanks
Yup! Just a little food coloring! 🙂
Great ideas!
