Shaped Bubble Experiment
May 03, 2011
Studying bubbles is a fun way to learn and review the scientific method. First, I do an experiment with bubbles made from three different dish washing liquids labeled A, B, and C. After examining them, the students write a hypothesis about which solution would make the biggest bubbles. They design an experiment in which they blow bubbles with each solution onto a table and measure the print left. They create tables and graphs of data and then write a conclusion.
Second, I pose the question: Can you blow a square bubble? We use the scientific method again to design an experiment. They come up with materials that are either square shaped or could be formed into a square such as pipe cleaners. Many students believe that if they create a square blower and use the best bubble solution, then they will be able to blow a square bubble. Do YOU know if it works?
