Friends and Heroes: A science experiment

We LOVE our Friends and Heroes curriculum!  Today we did science.  In the story, the boy Macky helps his father sell items like silver.  We learned how valuable it was all of those years ago.  We also learned about things like; luster, malleable, conductor and tarnish.  We then did a really cool experiment.  In the past our experiments have not been very successful but today it was!!!

We started with some very tarnished silver.  I had two rings that I have been meaning to take to get cleaned.

Then we put them into a pan lined with aluminum foil.

We brought water to a boil. (This is the mom part!).

Then we measured the baking soda.  It takes 1/4 cup per liter of water.  We talked about the different ways to measure and how each went together.  We also went over fractions again.

Then we added the boiling water and the baking soda to the pan.  The frothing was very quick!  And the tarnish came off just as quickly!

We used tongs to get the hot rings out and study them better!  We had a lot of fun today!
