Discover which brand of gum results in the largest bubbles.
Science projects don't have to be boring. One way to get young children interested in the sciences and the scientific method is to create science projects that are entertaining and educational. A bubble gum science project is a perfect example of a fun yet informative project. Although there are countless bubble gum science projects that could be conducted, one of the most interactive experiments is the bubble blowing project. This project uses multiple brands of gum to explore which brand creates the biggest bubbles.
Instructions
1. Purchase five different brands of bubble gum. Make sure the gum is bubble gum and not chewing gum. If possible, try to use the same flavor as well so that you are not introducing any added variables into the experiment.
2. State clearly what your problem is. The problem is the part of the scientific method that conveys the purpose of the experiment. In this case, your problem should be something like "What brand of gum generates the largest bubbles?"
3. State your hypothesis. Which brand of gum do you think will generate the largest bubbles? Add a sentence or two to provide insight into your prediction.
4. Lay out each brand of gum. As you conduct each step of the experiment, write down the step. This will be your project's procedure.
5. Chew the first piece of gum for 10 minutes. Once you have thoroughly chewed the gum for 10 minutes, begin blowing bubbles. You will want to blow 10 bubbles for each brand of gum. Attach a paperclip onto your ruler to mark the zero point. Attach the other paperclip to make a homemade caliper. Slide the other paperclip along the ruler to measure the diameter of each bubble. Write down this diameter on a piece of paper. By the end of the experiment, each piece of gum should have 10 measurements.
6. Take an average of the bubble sizes for each brand of gum. To do this, you will want to add your 10 measurements, and then divide this total by 10. These raw numbers and results are your experiment data.
7. Write your experiment's conclusion. Which bubble gum had the largest bubbles on average? What was the smallest? Was your hypothesis correct?
