Transcript of Bubble Science
Other animals have bubble experiences of their own! Watch both clips- the youtube one and the clip in the link.
Pick 2 of the following prompts to respond to. Go to http://padlet.com/britniepowell/realbubbles
What characteristics do bubbles have?
Share a specific memory you have involving bubbles.
How are bubbles used in the science?
Where in real life, besides playing with bubbles, do we encounter them?
What do you know about bubbles?
Explore and Observe
You need the follow materials:
3 bubble solutions following this recipe:
1 cup water
4 tablespoons liquid soap (1 solution needs dawn, 1 solution needs baby shampoo, 1 solution needs greenworks dish soap)
2 tablespoons light Karo syrup
Bubble wand (I use a cut pipette but a straw will work too)
Scientists are constantly noticing things and wondering things. Today as you play around with bubbles, generate a list of things you notice and of questions you have. Often times you can turn your observations into questions.
Spend time blowing bubbles, playing around with your bubbles, and trying things out.

Designing an Experiment
At this point in the game, when I do this with students, I allow them to pick a testable question they are interested in trying to get an answer to. They work in teams based on interest and together design an experiment. They then present their findings to the class. I do this as my initial science unit so that I can assess what science process skills my students have. Then we do a "model" experiment together, which I guide them through, step-by-step.
As we are not sitting down together face to face or even meeting online all together for this, we will do a modified approach to this. Instead of us collaborating in designing the experiment, I will give you the directions for the lab.
Question: Which bubble solution will blow the biggest bubbles?
Hypothesis: Your hypothesis needs to have your thinking and the reasoning behind your thinking. Often times a hypothesis is structured as: I hypothesize.... because...
If (select the bubble solution of choice) is used, then I hypothesize the biggest bubbles will be blown because...
Share the Data
Everyone needs to have their data posted here http://padlet.com/britniepowell/bubbledata
and post your list of observations and questions. Include a pic or video clip of your bubble adventures!
by January 27th.
Spray 4 full sprays of H2O onto a table surface.
Place 1 teaspoon of Dawn solution onto surface.
Dip wand into bubble solution.
Blow bubble onto table slowly and steadily until it pops!
Use a ruler to measure bubble diameter in centimeters (be sure you find the furthest distance across your bubble that you can before recording the data).
Repeat with this solution 4 more times (so you end up with 5 pieces of data for Dawn).
Clean off table and bubble wand.
Repeat entire experiment with the other two solutions.
(This is what we are testing!)-
Different bubble solutions.
(What we are measuring, what we are seeing if it changes because of what we are testing)-
We need to be sure we do everything exactly the same each experiment with the only change being the kind of bubble solution.
Collect your data!
Be sure to create a table to help you keep track of and organize your data.
**Tables are not graphs! You shouldn't be graphing your data yet. Here's an example of a data table for our question:
Let's begin by looking at some bubbles...
Think about what you notice.
We even have bubbles in space: (go to the link!) https://www.noao.edu/image_gallery/html/im1029.html
