I wanted a fun way for my students to collect and evaluate data. To engage students, I made this a challenge. The question I posed to the class was “Which group is able to create the largest soap bubble?”
Each group brainstormed what might help them create their soap bubbles. They were informed I had a variety of soaps from the store. It was important that students NOT mix soaps but work on different variables. Students recorded data each time they changed a variable. Note - most groups started without a variable and called this their "control test." There was an open range of variables students might test including: baking soda, epson salt, oil, sugar, salt, and vinegar. If I could find it (and it was safe), they were allowed to test it.
Students used milk straws to blow their soap bubbles. They collected data for several attempts and then determined what to change with their variable. One group decided to begin blowing their bubble on the table surface. Their bubble was larger than they created blowing in the air. They quickly spread soap solution on the table and began blowing again. The image shows their “winning bubble.”
