Lesson 1 - Monday, Apr 28
Today in science: Building on the work we did last Friday on atoms, elements, molecules, and compounds, students completed and self-graded four different sets of practice problems consisting of 48 different practice questions (students were not required to complete the fifth practice set, which is about the percentage of gas molecules found in the Earth’s atmosphere). This work gave us the chance to add to our developing understanding of the relationships and differences between each of these key chemistry terms. We did this work in preparation for Friday’s Quiz, which will have questions similar to those found on the 48 practice problems.
At the end of D period’s science lesson, students were asked to begin formatting their science notebook for INV#12 – Food Testing w/Reactions, which we will complete during Lessons 2-4 this week.
Homework: Students should begin preparing for Friday’s Atoms, Elements, Molecules, & Compounds QUIZ by not only using today’s 48 practice problems, but ALSO the different resources Dr. M sent to students via the Google Classroom Stream.
Lesson 2 - Tuesday, Apr 29
Today in science: The next 2-3 science lessons will involve learning how to identify three of the key nutrient molecules in foods commonly eaten by students at TASIS. Using four different indicator solutions (iodine, Benedict’s, Biuret, and ethanol), students will learn and practice laboratory techniques such as grinding, crushing, blending, filtering, pouring, measuring, estimating, recording, and interpreting. Today, we performed four nutrition molecule tests–two for carbohydrate molecules (one each for both simple and complex sugars), one for protein molecules, and one for fat/lipid molecules–on the flesh of a green apple, which we transformed into apple juice with a mortal and pestle (D period) or hand blender (E period) to work better with the indicator solutions.
Homework: Students should continue preparing for Friday’s Atoms, Elements, Molecules, & Compounds QUIZ by not only using today’s 48 practice problems, but ALSO the different resources Dr. M sent to students via the Google Classroom Stream.
Lesson 3 - Wed, Apr 30 (D) & Thu, May 1 (E)
Today in science: Students continued performing food molecule tests. Working in small teams, students selected from the available foods (e.g., banana, yogurt, fruit juice, milk, cereal, celery, etc.), predicted which food molecules they think will be present, prepared the raw foods for testing, and then performed the tests. Students recorded their test results on a pre-prepared handout provided by the teach.
Homework: Students should continue preparing for Monday’s Atoms, Elements, Molecules, & Compounds QUIZ by not only using the 48 practice problems, but ALSO the different resources Dr. M sent to students via the Google Classroom Stream.
Lesson 4 - Friday, May 2
Today in science: At the start of today’s lesson students did a thorough clean-out of their science mailbox. Students were then asked to put the data collection sheet used during INV #12 – Testing Foods into a properly formatted page of their science notebook. To this resources, we added a few investigation conclusion statements. Dr. M then made sure students understood what materials/resources can be used when studying for Monday’s Atoms, Elements, Molecules, & Compounds quiz (he also made students aware of additional study resources entered into the Google Classroom Stream.
Homework: Students should continue preparing for Monday’s Atoms, Elements, Molecules, & Compounds QUIZ by not only using the 48 practice problems, but ALSO the different resources Dr. M sent to students via the Google Classroom Stream.
Announcements...
The DRIVING QUESTION of our current unit is: How can we make something new that wasn't there before?
D period homework collection days: Wednesday & Friday.
E period homework collection days: Tuesday & Thursday.
We will have the Atoms, Elements, Molecules, and Compounds QUIZ on Monday!
