Bubble Solutions Experiment

1st Graders learn about the experimental process using bubbles!

We learned a little bit about how scientist set up their experiments while blowing bubbles.   What could be more fun?

First, we talked about how scientists have a QUESTION they want to answer.

Next, we discovered that scientists need  to
GATHER BACKGROUND KNOWLEDGE.

They do this by: 

• observations
• reading what other scientist write
• talking to experts

Using all of the knowledge they gathered, scientist make a PREDICTION

Then, we explored how scientists set up an EXPERIMENT and pay special attention to the conditions.

• Constants:  trying to keep everything the same except what they are testing
• Variable: the one thing that is different. 

All bubble solutions had soap and water.  However, we added corn syrup to B and Glycerine to C.

We conducted many TRIALS using the same conditions (and our classmates) and recorded our DATA on the white board.

We found that solution C lasted the longest most often, even though we predicted B would.

We made a CONCLUSION  and talked about other ways we could change this experiment.
