Monday-Wednesday, March 2nd-4th
Today in science: The ‘official’ arrival of the coronavirus in Ticino last week, and the return of TASIS students to classes this week, created an opportunity for Dr. Merritt to begin addressing issues of contagion, detection, and prevention (e.g., personal, familial, and communal hygiene practices) related to viral infections. In addition to class discussions and simply demonstrations (e.g., how to cough and/or sneeze in public spaces), Dr. Merritt used a short educational video to introduce students to a Darwinian account of the origins of the new (or novel) coronavirus, COVID-19. Because parts of this video will form the basis of the content and/or discussions of the next 2-3 science lessons, it has been embedded for easy viewing below.
After discovering that viruses contain a substance called “DNA” (or “RNA”), students were given the opportunity to learn a bit more about this incredible chemical substance from another Stated Clearly video titled, “What is DNA and How does it work?” This video has also been embedded for easy viewing below.
Homework: There is no science homework on Monday, Tuesday, or Wednesday night.
Thursday, March 5th
Today in science: While four students completed the make-up of their Acids & Alkalis test, the rest of the class practiced using electric balances to measure out pre-determined masses of table salt (e.g., 11.7 and 5.6 grams). After demonstrating competency with the balances, students were asked to 1) measure 125 mL of tap water and add it to a 250 mL beaker, 2) record the temperature of the beaker on a half-sheet of paper, 3) add the 5.6 grams quantity of salt to the beaker, and 4) time (and record) how long it takes to fully dissolve the 5.6 g of salt in the 125 mL of water. After completing the four-step protocol, students were asked to try and provide a detailed written explanation of what happen to the salt.
Homework: There is no science homework this weekend.
