A couple of months ago, I ran across a science activity on a third grade teacher's website. The teacher used gobstoppers to teach the scientific method. I can't find the website now and I am wondering if anyone is familiar with this activity. If so, can you post it?

There is a gobstopper activity in Rising to the Challenge of the National Science Education Standards. It is a book put out by NSTA and I ordered it from their website. The acitivity is in the primary grades book. There is an intermediate grades book as well, I don't know what's in that one. They have three entire units (seeds, matter- uses candy for materials, and dinosaurs) that teach all of the process skills: observing, communicating, classifying, measuring, predicting, inferring, defining operationally, formulating models, and investigating. The gobstopper activity is the observation one for the matter unit. It involves dropping a gobstopper in water, observing, and recording the changes, because... gobstoppers are made in layers and it will turn at least 4 colors until it get down to the sweet tart type center. I have used nearly all the acitivities in both the matter and dinosaur units and they are really well done. It does take some time to get through them. I will be using the dinosaurs this year.

I went out on the web and found a lot about the gobstopper lab because I thought it was an intriguing idea. I'm sharing what I pulled together.

I was wondering if this must be done with gobstoppers or will any jawbreakers work? Has anyone done this and just used generic jawbreakers? Thanks

So cool thanks for sharing! I will definitely do this.

I think this would be great on one of those first, very hot afternoons back at school. Thanks for sharing.

*Where each child places a GS in their mouth, guess what the GS's next color change will be and time the changes.
*We also used a petri dish w/water, placed a rainbow of GS and see how the colors spread, time the changes, and then see what the final color of the water is when done.
*How long does it take for you to finish a GS?
