G7 Week 05

Last week in science!

Monday, October 5th

Today in science: As a way of addressing the many tree questions asked by students in class last Friday, Dr. M asked students to go outdoors and collect one whole, undamaged chestnut (castagne) for further study. After recording the mass of the chestnut (on multiple electronic balances in the classroom), students were asked to 1) calculate the average mass for the class data, 2) compare the mass of their chestnut to the mass of the (imaginary!) ‘average’ class chestnut, and 3) write a true statement about the mass of their chestnut when compared to the average chestnut.

C period chestnut mass data (all #s in grams): 13.1, 7.4, 14.3, 13.4, 10.4, 11.2, 15.3, 13.9, 14.8, 15.1, 16.15, 16.2

H period chestnut mass data (all #s in grams): 8.0, 8.7, 13.3, 11.6, 5.4, 10.3, 13.8, 3.5, 12.1, 11.9, 9.7, 8.9, 1.2, 10.8

Homework: There is no science homework tonight.

Tuesday, October 6th

Today in science: 24 hours after they first removed their chestnut from its natural campus ‘habitat,’ students were asked to again record the mass of their chestnut in their lab notebooks. Dr. M organized a Google Sheet to record the class data from both days (Day 0 and Day 1) and both periods (C and H). Students very quickly noticed that the mass of all of the chestnuts kept indoors decreased by an average of -0.6 grams over a 24 hour period.

When Dr. M wondered (aloud) if chestnuts kept outdoor would follow this same mass-loss pattern, C period students asked if they could set up a concurrent chestnut investigation to address Dr. M’s wondering. Dr. Merritt agreed that it was not only a great idea, but also quite doable! And so, in the time remaining C period students collected mass data for a second chestnut (“Chestnut 2” or “Outdoor chestnut”) and then hid the chestnut somewhere on the campus so that it would go undisturbed over the next 24 hours. H period students were encouraged to perform a similar investigation so that they could compare their results to C period.

Homework: There is no science homework tonight.

Wednesday, October 7th

Today in science: After creating a new data table in their lab notebooks in which to record their indoor and outdoor chestnut investigation data, students were asked to collect and record their mass data for their ongoing investigation(s). Dr. Merritt has also set up C and H period spreadsheets–one for the INDOOR chestnut data and one of the OUTDOOR chestnut data–where all the days of collected data can be viewed. In H period, some students were asked to send Dr. M an email before leaving class with their answer to the question, “It’s clear that your chestnut is losing mass, but where is the mass of your chestnut going?”

Homework: TASIS science teachers are not allowed to assign homework on Wednesdays.

Thursday, October 8th

Today in science: After measuring and recording the mass of both their INDOOR and OUTDOOR chestnuts, students were asked to create two line graphs on the same side of a single sheet of graphing paper. On both graphs, the X-axis was set aside for “Days” (0-10) while the Y-axis was set aside for “Mass” (in grams). The data points and connecting lines for the INDOOR chestnut data were done in RED while the data points and connecting lines for the OUTDOOR chestnut data were done in BLUE. Examples of these two line graphs can be viewed in the Notes Portal.

Homework: There is no science homework during Family Weekend, but it is possible that some H period students did not finish their two line graphs in class. If that is the case then they should try to finished them before next Tuesday’s science class (there are no classes on Monday).

Friday, October 9th – C period only (no H period)

Today in science: Because of the alternate (half-day) school schedule, H period students did not have a science lesson today. C period students were thus given time to continue working on their indoor/outdoor chestnut investigation, which included making 3 line graphs to represent what has happened to the mass of the chestnuts during the investigation through today.

Homework: There is no science homework during Family Weekend. Since there is no school on Monday, the next science lesson is on Tuesday, 13 Oct.
