Science: Chemical Test Experiments

posted Nov 19, 2013, 1:11 PM by Unknown user
We are practicing our science process skills and learning about how to set up experiments using controls and variables.  Mrs. Hersey has given us five different white powders, and we have been setting up experiments to test them and see how matter changes.  The tests we've done so far are observation of the physical properties, water, vinegar and iodine tests.  We have had some surprising results.  Next, we'll make water mixtures and find out about solutions and suspensions.  Later, Mrs. Hersey will reveal what these household white powders really are.  The final challenge will be that Mrs. Hersey is going to mix two powders together and we'll have to decide which chemical tests we'll do to discover which powders they are.  Science rules!!!
