How did your sugar crystals grow?  I ate all of mine and then I had to brush my teeth very well.  What about your salt crystal garden?  Were you able to grow some beautiful crystals?  Another fun activity is to shape a pipe cleaner into whatever shape you want and then put it in the jar with baking soda (experiment 1) and see what happens.  I also found some fun web sites that will teach you more about crystals.  Enjoy!
