Analyzing and interpreting data Preparation: Have acid of an appropriate concentration (a concentration of 0.1 M 0.5 – Using mathematics and M) prepared prior to having the students start the experiment. computational thinking Facilitation of Learning Experience: Constructing explanations (for Inform students that they will be ranking metals from the video and lab from science) and designing the most reactive in acid to the least reactive in acid. Emphasize the solutions (for engineering) importance of carefully sanding each metal sample to prepare the surface for a possible reaction. It is important to allow students to determine how to Engaging in argument from evidence best organize their data collection in their laboratory notebooks, and how to organize their approach to the lab so that they know when they have Obtaining, evaluating, and completed all of the necessary tests. If a group is struggling with communicating information organization, they can be asked questions such as: How many do you think you should repeat each test? Is it easy to tell by looking at your lab notebook whether or not you have finished collecting all the data for the experiment? Are you recording what procedure you are following during the investigation? If you refer back to your lab notebook in a month, will you be able to tell what you did, what you observed, and what you were able to conclude from that data? Transition: Students are to check to make sure that the data they choose to collect during their experiment allows them to make a ranking supported by evidence from their investigation.
