Grab the goggles, it’s Chemistry

on February 28, 2013

4th grade students started their study of chemistry today and investigated the difference in solubility of sugar in cold water and hot water.   After the investigation, students had questions they wanted to test next time in the lab:

would salt and sugar dissolve the same?
How would the sugar dissolve at different temperatures?
If I poured the warm water and cold water together, how would sugar dissolve?
how much sugar fits into cold water?  how much sugar fits into warm water?
What would happen if you changed the temperature in a baking soda and vinegar rxn?
What would happen if you mixed the warm and cold water?

How could you test to see if the cold water or warm water holds more sugar?
