Students spent last week in the Science Lab performing 2 tests to determine what substance and liquid went missing from the lab.
Test 1: Chemical reactions (how different substances react with specific liquids)
Students were presented with four unknown mystery substances, which they observed using their senses. Next, in their science investigation teams they added specific liquids and watched for indications of reactions.

Test 2: Acid/base test (test the alkalinity of the liquids)
With a different set of mystery liquids, students used litmus paper to determine the PH level of each liquid.

Conclusion:
Students examined their experimental results, and, using an information chart drew conclusions about what the identity of the mystery powders and liquids. They are currently working to present their conclusions as part of a "theft report" for Mr. Lonsberry.
Watch for a Summative Assessment of their knowledge regarding physical and chemical changes.
