G6 Week 18

Last week in science!

Monday, January 21st

Today in science: The main theme for today’s science lesson was “acids & acidity.” To begin understanding acids, Dr. M invited students to participate in an acid-tasting event in which students were given samples of the following fruits: orange, clementine, and pink grapefruit. During the tasting, students were asked to record 3 words in a table in their Lab Notebooks related to the following sensory categories: smell, touch, sight, and taste. Tomorrow, we will continue the tasting event with fruits such as lemon, lime, and pineapple, but also with a variety of acid-containing vinegars such as balsamic, apple, apple-flavored balsamic(!), rice, and both red and white wine vinegars.

Homework: There is no science homework tonight.

Tuesday, January 22nd

Today in science: The main theme for today’s science lesson was again “acids & acidity.” We continued yesterday’s tasting event by sampling fruits such as lemon (but also lemon + a sugar cube!), lime, and lots of pineapple. By far, today’s most popular item was Dr. M’s new invention, pineapple carpaccio. Tomorrow, we will conclude our tasting adventure by sampling a variety of acid-containing vinegars such as balsamic, apple, apple-flavored balsamic, rice, and both red and white wine vinegars.

Homework: At the conclusion of today’s science lesson, students were asked to send Dr. M and email (brett.merritt@tasis.ch) that lists the TASTE words recorded in their Lab Notebooks for all 6 of the fruits tasted in class on Monday & Tuesday. Dr. M has asked only for the tasting words and not the words used for the other senses. For example…

ORANGE: sour, sweet, tropical

Wednesday, January 23rd

Today in science:  The main theme for today’s science lesson was again “acids & acidity.” After talking briefly about the difference(s) between taste and touch/feel words, we continued yesterday’s tasting event by sampling a variety of vinegars including balsamic, apple, apple-flavored balsamic, rice, and both red and white wine vinegars.

Homework: At the conclusion of today’s science lesson, students were asked to send Dr. M and email (brett.merritt@tasis.ch) that lists the TASTE words recorded in their Lab Notebooks for all 6 of the VINEGARS tasted in class on Wednesday. For example…

APPLE VINEGAR: sweet, strong, sour

Dr. M has asked ONLY for the tasting words and NOT the words used for the other senses. Please don’t forget to include your Student # in the Subject of your email.

Thursday, January 24th

Today in science: The main theme for today’s science lesson was “the chemical structure of two acids.” Students were asked to draw a single molecule of citric acid, which was the acid contained in the citrus fruits we tasted on Monday & Tuesday, as well as a single molecule of acetic acid, which was the acid contained in the vinegars we tasted on Wednesday. In each case, students were asked to count the number of atoms and chemical bonds (both single and double bonds) needed to form one molecule of each of the two acids. The two color-coded diagrams created by Dr. M in class, which students were asked to copy onto two separate pieces of drawing paper, can be seen in the Notes Portal. At the end of the lesson, Dr. M gave each student a small sample of purified, food-grade citric acid crystals to taste.

Homework: There is no science homework tonight.
