G6 Week 16

Friday, January 12th

Today in science: Students were asked to check in last night’s homework assignment (Question Set 1.2) with Dr. Merritt at the start of the class period. Students were then asked to correct their answers during a class discussion. Dr. Merritt then asked students questions about the mass of a sealed bag of ice cubes before and after melting them. This conversation set up the idea for an activity that we occur on Monday.

Homework: Students should complete the FIVE questions found on the “Question Set 1.3: Distilling Water” worksheet found near the back of the new Matter and Molecules unit. After reading pages 5-8 very carefully, students should use the information found on these pages to help them construct their answers.

Thursday, January 11th

Today in science: Dr. Merritt gave students Chapter 1 (“States of Water”) of the new Matter and Molecules unit. As a class, they read the Introduction and Lesson 1.1. Students then witnessed a distillation demonstration set up by Dr. M, in which they saw evidence that water vapor is in fact invisible. An additional demonstration was performed after the students requested the addition of some red food coloring to the water source.

Homework: Students should complete the SIX questions found on the “Question Set 1.2: Distilling Water” worksheet found near the back of the new Matter and Molecules unit.After reading pages 1-4 very carefully, students should use the information found on these pages to help them construct their answers.

Wednesday, January 10th

Today in science: Students were asked to redo last night’s homework assignment in the proper format and with the proper materials. Students were then asked to give written responses to the following writing prompts:

1. Matter is…
2. A solid is…
3. A liquid is…
4. A gas is…

After completing the writing task, students were given identical-sized cubes made of various pure elements (aluminum, copper, and lead) and asked to explain–working in teams of two–how/why these identical-sized cubes could have different masses!

Homework: There is no science homework tonight.

Tuesday, January 9th

Today in science: H period does not meet on Tuesdays.

Homework:

Monday, January 8th

Today in science: Students were given the challenge of filling a plastic bag full of snow and then trying to melt it in the classroom as fast as possible. This exercise was an introduction to some work we will do this week on water and phase (or state) changes. This is part of a larger unit called “Matter & Molecules,” in which students will be introduced to the kinetic molecule theory.

Homework: Write a complete sentence using each of the following pairs of key words. While Dr. Merritt would like you NOT to use the Internet, he would still like you to try and write sentences that you think are scientifically accurate (it is OK if you eventually learn that the idea in your sentence is not accurate–for now, just try your best). In total, you will write 3 sentences.

1. ATOM (or ATOMS) / WATER
2. MOLECULE (or MOLECULES) / WATER
3. ATOM (or ATOMS) / MOLECULE (or MOLECULES)

You can reverse the order of the key word pairs in any of your sentences. You can use either the singular or plural form of the word–it’s your choice.
