Fun With Science

We had so much fun with our science experiments today!  We are using the Usborne Science Activities Book 2.  Today we had experiments with fizz.

First up:  raisins and soda.  Pour some clear soda into a clear glass or jar.  Add a couple of raisins.  The gas bubbles in the soda will grab the raisins and lift them up.  As the gas escapes, the raisins will fall back down, but come up again when more bubbles stick to them.  This is really funny to watch!

Next:  baking soda and vinegar.  Just add a little of both to a cup and watch what happens.

And: fizzies in your mouth.  A little citric acid plus a little baking soda gets you…nothing!  You need to add liquid.  But first, mix some powdered sugar in for taste, then put a pinch of the mixture in your mouth.  Sort of a sweet and tangy fizzy thing going on.  Fun!  Put some of the mixture aside for Daddy to try when he comes home.  You can also watch what happened in your mouth by taking a spoonful of the mix and adding water to it.

By the way, if you are using the Usborne Science Activity books, Sonlight has some great DVDs to go along with them.  Every experiment in the book is demonstrated on the DVD by a fun and often silly science dude.  They are great to compare your own experiments with our to use if you don’t want to do them yourselves.  Especially if you can’t get all the materials needed.  Sonlight also sells science kits to go along with the books and DVDs so that you do have things like citric acid on hand.  I’m not affiliated with Sonlight in any way, just a big fan of their curriculum.

More Mac and Cheese, please!
