The purpose of this lab is to use the Scientific Method to compare three types of measurements using baking soda, vinegar and 3 balloons. Students will design their own experiment to determine how much baking soda needs to be used to expand the balloon to the biggest size.
This is a super fun lab that my students did a couple of years ago. They love measuring baking soda and vinegar and seeing the balloons rise. There are lots of questions that go along with the lab sheet and students will graph their information at the end of the lab. Measuring their balloons and vinegar bring in a math portion. I found the idea of the lab online and created my own materials.
This Zip file includes Lab sheet which is 3 pages long and a powerpoint that is 10 slides long.
