Chemistry 1 – Today we continued to collect data from the six part Mass and Change Lab. Above you see a group burning steel wool. After data for all six parts of the lab were collected groups shared their data via a Google Form and worked on drawing particle diagram models for the before and after of each situation.
Physics 1 – Groups had collected data about their robot, from that data we worked a whole class to line up three robots from fastest to slowest http://youtu.be/CWGhM_7fgh8 . Although some data was originally graphed in different units or with different variable on the x and y axis both classes were able to successfully predict the outcome. From there I had each group create a graphical model of the “race.” Here is some examples of what one class came up with:
Chemistry 2 – We precisely diluted a 0.40M solution of nickle (II) sulfate into 4 more dilute solutions. Using the dilution formula of C1V1 = C2V2 we calculated the concentrations of the diluted solutions. We will be using those tomorrow for a Molarity Lab in which we need to know Concentrations of the solution.
