Making Bubbles Experiment

Before going to bed each night, my son likes to read. He will usually read story books but one night this last week he took a science experiment book to bed and started reading. This could only mean one thing....a science experiment was about to happen. 

My son had found an experiment called blowing bubbles, in our science book 356 Science Experiments by Glen Singleton . This experiment was about testing different household detergents to find which one is best for making bubbles.

 
Here is a list of the different materials we used for our bubble experiment:
  • four bottles or jars with water
  • different household detergents
  • bubble blowers
  • note pad and pen
  

We set up our experiment by filling the jars with water. We selected shampoo, dish washing liquid, shower gel and body wash as our household liquids that we were going to test. We then added two tablespoons of each liquid into the different jars.
 

We used our note pad and pen to write a label for each jar of liquid so we wouldn't get them mixed up during our experiment. Once our experiment was set up we made a prediction on which liquid we thought might make the best bubbles. We then left our experiment to sit over night before testing it in the morning. 

The next day we started testing our experiment. We quickly eliminated shower gel from our experiment as it made no bubbles at all!

When I asked my son how we were going to record our results, my son came up with the idea of using a tally chart. We have used tallying plenty of times before for counting and recording different things. So we worked out that we would attempt to blow bubbles ten times for each of the three liquids and record how many bubbles it made. We concluded that shampoo was the best household liquid to use to make bubbles.

What I love about this learning activity is that it was all child-lead from reading the science book to choosing the experiment and recording his findings.
