Earned Activity: Elephant’s Toothpaste

Whew!  I has been a while since I have posted.  We had an amazing spring break and Easter and I am trying to get back into the swing of things at work.  As the year begins to wind down I find I need to extra fun activities to keep the kids (and me) engaged in class.

I have students earn “minutes” each day towards an earned activity.  It is an extra activity that ties in with the current curriculum (or sometimes just for fun).  It is always a FUN activity that the student’s look forward to and motivates them to behave in class.

Once students have earned enough minutes, we set aside time in the day to do the activity.  This week we did Elephant’s toothpaste.  I picked up the ingredients: Yeast, 6% hydrogen peroxide, soap, and empty water bottles.  I got the hydrogen peroxide at Sally’s beauty supply and I am a sucker for a deal so I bought a gallon (it was only $2 more than the half gallon)

There is something so magical about this reaction – steaming coils of foam erupting from the water bottle!  It never gets old!

I have it written up for different grade levels in my TPT store. Check them out:  K-2 focuses on the scientific method, 3-5 focuses on physical and chemical changes, and 6-8 focuses on chemical reactions.
