Today we decanted our crystals- wow- do they look cool! It was interesting to see how many crystals also formed on the surface of the jars. It was also interesting to see the color results. The crystals are drying overnight and will come home tomorrow. Hopefully they will survive the trip!


These are the crystals that formed on the jar itself. Some students added much more solute (borax) to their solvent (water) than others. The solutions that contained more borax led to much heavier deposits on the glass.


Another "after" shot of the jar. The crystals were hard to scrape out!


One student's crystal snowflake. Interesting choice of color for a snowflake.


Another nice snowflake.



In social Studies we read through page 147, and completed page 32 in the packet. That is homework for those that didn't finish.
