Perkins School for the Blind Secondary school student Paige Nason shares her science fair project.
The reason why I picked this bubble experiment is because it looked interesting and fun. I thought it might be cool to see which bubbles would be better for my nieces and nephews to play with and you can never be too old to play with bubbles.
When people come to my table (at the science fair) I want them to be able to see the difference between the bubble solutions and which solution worked the best. Then maybe they can go home and make bubbles for themselves or their children.
When people come to my table they can blow bubbles to see which ones last the longest. To make it accessible for someone who’s visually impaired or blind I will have plastic balls or marbles that would look and feel like a bubble. I will also make bubbles on the PIAF paper. ( paper that creates raised line tactile images)
Here are some vocabulary words that will help you understand my project.
In preparation to carry out this experiment, I asked a Scientific question:
“Which bubbles work better: the bubbles you buy in the store or bubbles you make with glycerin?”
And made a Hypothesis:
My hypothesis is that the glycerin solution will make better bubbles than the store bought solution.
Store bought bubble solution
Bubble solution made with 15 ml glycerin
Bubble solution made with 100 ml glycerin
Adding more glycerin it made a bigger diameter and the bubbles lasted longer.
I added 100ml of glycerin and the bubbles were bigger and lasted longer. They felt stronger. The bubbles even bounced. Originally I added 15ml of glycerin and the bubbles were small and popped really quick. I experimented with a variety of ways to blow bubbles. To blow bubbles I used bendy straws, pipettes, small funnels, and big funnels.
