G7 Week 18

Last week in science!

Lesson 1 – Monday, January 18th

Mars Mission (Day 1): After watching the introductory video below, students created a new Lab Notebook entry in which they have been asked to record the Mars surface temperature–both in degrees C and degrees F–for the next 30 days. The data source for the Mars surface temperature is accessible here. After the video, there was some general class discussion as well as some student questions.

Homework: There is no science homework tonight.

Lesson 2 – Tues/Wed, January 19-20th

Mars Mission (Day 2/3): After recording today’s Mars surface temperature data, students were asked to get to know more about the Martian environment as a key first step their mission exploration. With that in mind, students were asked to get to know the Martian environment by doing the following…

1) Go to the SCIENCEsEDiment Grade 7 Notes Portal and copy and paste the 14 questions listed at the top of that document into your Digital Lab Notebook (which, remember, is in your Google Science Classroom).

2) Use NASA’s “Mars in a Minute” 14-video series to answer to 14 questions (these videos are linked to a YouTube playlist in the “Week 18 (Jan 18-22)” section of your Google Science Classroom).

3) In your Digital Lab Notebook, be sure you included BOTH the question AND the answer. All “Yes” or “No” answers must be explained with supporting sentences.

Homework: Please finish answering the 14 questions before the start of your next science class. You do not need to submit the assignment in Google Classroom because Dr. M already has access to your Digital Lab Notebook.

Lesson 3 – Wed/Thurs, January 20th-21st

Mars Mission (Day 3/4): After recording today’s Mars surface temperature data, students were asked to get a better feel for the distance(s) between the Sun, the Earth, and the rest of the planets within our solar system. To do this, Dr. M walked students through the short video below before then explaining the modelling challenge.

So, here are the steps we followed in class…

1. Watch Solar System Size & Distance video (above) – discuss the limitations identified in the video.

2. Introduce modelling materials = 5 m string, wooden craft beads

3. Introduce distance calculations worksheet (your personal copy is in the Google Science Classroom!) and have students complete their distance calculations.

4. Distribute modelling materials and give students time to begin model construction (useful video resource: How to knot against a bead AND How to tie double and triple knots).

Homework: There is no science homework tonight.

Lesson 4 – Friday, January 22nd (Semester 1 ends)

Mars Mission (Day 5): After recording today’s Mars surface temperature data, students were asked to go back to work on their solar system models. Recall that the sole focus of our models is on showing the relative distances of the planets to the Sun with accuracy.

If you want to see someone who managed to build a more realistic model of our solar system, in which the distances of the planets are scaled accurately but so too are the SIZES of the planets and their ORBITS around the sun, then you should definitely watch this National Geographic video of a man who built such a solar system model in an American desert. (Spoiler alert: he chooses a glass marble to represent the size of the Earth.)

Homework: There is no science homework this weekend.
