Today in science: Although some students needed some additional time to complete the last portion(s) of their Electrical Circuits unit test, most students were asked to create a data table in their Lab Notebook to house their Leaf Investigation data, which required students to measure the length (l) and width of 25 leaf specimens collected from the TASIS campus. In addition to using the scientific style of measurement when using their rulers (i.e., stating their uncertainty in the correct “+/-” format), students were asked to think about measuring techniques designed to ensure more accurate/precise measurements.
Homework: There is no science homework tonight.

Today in science: After a short lesson designed to show students how (and why) students make data tables the way that they do, Dr. M gave students time to continue measuring their leaf specimens and to record their measurement data in their carefully constructed data table.
Homework: For those who were unable to do so during Wednesday’s science lesson, students should try to finish making and recording their length and width measurements for all 25 leaves in their leaf collection. All measurements should be recorded in the data table created in class. If students cannot finish this assignment within 20 minutes, then they will be given 10-15 minutes to do so in Thursday’s class. However, the expectation is that the 20 minutes dedicated to this task at home is concentrated and uninterrupted.

Today in science: After checking for the completion of their leaf collection data tables, Dr. M showed students how to take the data from their data table and transform it into a particular type of graph: a frequency histogram. This transformation required a basic data analysis exercise in which students had to 1) determine the range of length (and width) measurements, 2) divide the range into inclusive categories such as 0-5 cm, 6-10 cm, 11-15 cm, etc., and 3) count up the number of leaf specimens that fell into each category. The final histogram was done by hand (using a ruler) on graph paper.
Homework: There is no science homework during the long weekend.
