Day 17 – Mass and Change Lab Analysis

Wed Sept 25, 2013

Google Form Responses

Chemistry 1 – We began class by looking at the overall data all groups had from the six part Mass and Change Lab.  This was done by having groups share their data via a Google Form, and then we looked at the Summary of Responses provided by the Google Spreadsheet.  Each small group then was responsible for creating a WB for one of the parts of the lab.  On the board they needed to include 1) a summary of the class results 2) an explanation(s) of those results, including possible errors, and 3) a particle diagram that models the situation and results.

2013-09-25 14.22.31 2013-09-25 14.22.46Physics 1 – Lab groups were given two robots.  One pre-programmed and one not programmed at all.  Students were shown the simple computer program that can program the robots by drawing a graph of the motion they would like the robot to perform.  Along with the two robots each group was given a distance at which the two robots needed to start apart from each other at.  Their goal was to get the two robots to end AT THE SAME TIME AND PLACE.  After each group successfully completed the challenge they were asked to model the situation on a graph.  These will be looked at and discussed tomorrow.

NOTE: My inspiration for using robots to learn about motion came from Matt Greenwolf, and the funds for purchasing them from WSST.

Chemistry 2 – Lab groups worked on collecting Absorbence data from various known concentrations of Nickel II Sulfate solutions.  Using Vernier Colorimeters groups were able to graph Absorbence vs. Concentration data.  We will use this data to analyze an unknown sample of NiSO4 solution and predict its concentration.
