Sylvester and the Magic Pebble

Our story this week was Sylvester and the Magic Pebble, by William Steig.  It is a great, classic story about a little donkey who find a magic pebble, and ends up accidently turning himself into a rock.  The story is a sad while his parents are looking for him, and he is giving up hope of ever becoming a donkey again.  It all ends well, however, and my kids really liked the story.

We decided that it would be fun to do an experiment with some "magic" pebbles of our own, so we brought out the water beads again (and yes, I still have my love-hate relationship with these monsters).  We filled a pan with them, and then left them out on the counter for four days.  We watched them shrink down to tiny pebbles as the water evaporated.

After they had completely shrunk and dried, we decided to see what would happen if we rehydrated them.  Instead of using plain water, we soaked them in Tonic Water, which glows under black lights.  We have some special black light experiments planned soon, so we are going to see if our water beads glow.

The beads rehydrated well, and the rehydration is much more spectacular to watch than the dehydration because it happens much faster.  Overall, it was a very successful experiment, and the kids got really into checking the beads to look for change.  And the beads did NOT end up all over the house this time (woot!)

As with most of our stories and experiments, I encourage the children to write about them in their journals.  I blogged here about how we use journals.  The journal not only offers great practice at writing and expressing themselves on paper, but it also allows us to easily look back over what we have learned and review and reminisce about our year.

  1. I love tonic water, so it never makes it to our experiments even when I specifically buy it for that purpose. I can't wait to see your glowing experiments.

  2. This reminds me, yet again, that I have a tonic water idea for my food blog that I keep forgetting about. I never thought of using it with water beads, though! Neat idea.

  3. OOoh waterbeads are perfect as "Magic Pebbles" they are indeed MAGIC!
