Today we revised our chemistry definitions using our flashcards for test that has been moved to tomorrow.
We did a number of experiments:

pH tested rainwater
did soap test on water samples
evaporated water to find presence of dissolved solids in water
used evaporation to separate salt from water

HW students are asked to pH test household substances with Universal Indicator Paper (please stay away from the dangerous ones such as bleach and drain cleaners)

After pH testing rainwater

Soap Test to see if Water is Hard or Soft

Separation by Evaporation

Dissolved solids in water seen after water has evaporated.

Salt separated from water after evaporation
