For this lab we added liquids together to create a fun foam! There were a couple of interesting points about this experiment…
Mixing the two liquids together caused a ‘reaction’. We talked about how it isn’t always the case that when you mix two things together a reaction occurs. The cause and effect of this experiment was lots of fun!
We made two colors of foam. By making yellow and red foam, we could also mix them and create another effect… a color change to orange!
When the foam was created, it was warm! The reaction is exothermic and a very small amount of heat was made as the foam was created. We compared and contrasted the difference in how the warm and cool foam felt.
As a fun side project, the foam created is just a very thick version of dish soap foam… so all of our tables in the classroom had a really good wash down that day!
Here are a few pictures of our fun….
