Wednesday, 1-6-10: Time to Look at the Borax Crystals

The crystals turned out very nicely. Take a look!

A spiral…..….beaker tongs..….pretzel..

That’s not all…there are more!

A letter “B” …. ….hearts……

and an assortment of others….

Students were able to use this activity to conceptualize ionic bonds and the structures they make. Also, the post-lab questions allowed students to connect the activity to various other concepts like mixtures, physical changes, physical properties, particles that make up the states of matter, and the molecular motion involved in phase changes.
