We corrected our responses to the crystals and solutions assignment sheet. Students conducted a short lab to determine if other liquids than water have strong surface tensions.
We completed our observations of the crystals we grew under six different manipulated variables and found that slowing the growing process resulted in larger crystals.
We completed our chemistry quiz #1 and reviewed the procedure and observations for our Crystal experiment.
We reviewed for tomorrow's exam and completed our study posters.
We tested six different manipulated variables to see what method of growing crystals is the most effective. We will complete our observations and conclusion tomorrow in class.
We corrected the review #1 and completed the second review package in class. Students who finished moved on to their poster project designed to help study the terms that are important to know for Friday's exam.
We used surface tension today to "float" some metal objects in water and made them sink using detergent. Students worked for the class period on their first chemistry review assignment using their notes and previous activities to respond to the questions. Though some students finished in class there may be some time on Monday to finish up and get support for any questions missed.
We completed our conclusion to the surface tension lab activity from yesterday. Students responded to questions related to their lab activity and identified the control, manipulated, and responding variables.
We completed our notes on emulsions and highlighted our review sheet before completing the questions on the front and back. If these matching questions were not completed in class, students are asked to have them done for tomorrow.
Students completed the decanting portion of their solutions lab and handed in their observations. We competed notes for the separation of liquids and solids and began our study of immiscible liquids.
