25 September Science 7 Parent Conferences; New topic for long-term observations; Relative motion; Acceleration

a. Mindful moment.

b. Review previous entry in DSN. Tumble Buggy report. Did you use the guidelines? I have noticed a few students calculate time/distance instead of distance / time. Some students did not include graphs. You will get feedback on your project as soon as possible.

Reminder:

Digital Science Notebook (DSN) 

An entry is needed for every class  

The purpose of the DSN is to help you:

  • Remember
  • Think
  • Learn
  • The entry should be dated and titled. Follow guidelines for organizing entries in topic folders AND for naming files. An entry should be completed by the beginning of the next class.
  • Each entry should include sentences, data and images. Use the next seven items as a checklist for completeness:
  1. Normal notes you would take. Information from the board, introductory instructions, etc. Special writing tasks.
  2. What you/we did
  3. What you/we saw
  4. What you/we talked about
  5. A sketch that will help you remember and think about something significant from the class. (It could be a sketch of a thing, a process, or an idea.)
  6. A photo that will help you remember and think about something significant from the class. (A photo different from a photo of notes on the board.)
  7. What you think and wonder regarding 1,2,3, 4,5, and 6 above. What are your questions, ideas and reflections? (You can write about what is significant in the sketch and photo. You can be creative, too. Try a poem or essay from time to time.)

c. Preview today’s blogpost.

d. Create DSN entry for today.

e. Questions. Is everyone ready for the Parent-Student-Teacher conferences?

  • * * * *
  1. *Class newsletter for parents. (Everyone will have responsibility at some time during the year). 3 volunteers. If no volunteers, will draw names randomly. There will be a deadline you must meet.
  2. We will check the weather before class. If it is not raining, we will take a tree walk around the campus. No today, but soon, you will select an individual tree to be your “partner tree” for the year. You will make repeated observations over a long period of time. You will need to keep a kind of partner tree diary. You will learn all you can about the species. More on this later. Today is an introduction to help you start becoming familiar with the natural landscape of the campus. This awareness of your surroundings will be important for WOW 7, too.

In case there is rain, we will carry out activities 3 and/or 4 (below).

Examine the following to begin “growing” your appreciation for trees. Begin curing yourself of “tree blindness.”

3. Make a new group of 3. These should be students you have not worked with before (or have worked with the fewest number of times). Update your collaboration chart / document. Names, topics, activities, dates, links (relevant blogposts, DSN entries, group documents and data)

You will receive a pullback car. Explore its operation. Do not overstretch the spring, but do find the point that gives maximum acceleration and distance.

Design a track (frame of reference) to evaluate how the speed changes. This will be very similar to your tumble buggy procedure. Find the times to reach various distances. Make a distance vs. time graph to display your results. Calculate the average speed for zero meters to the maximum distance you measure. Can you find average speeds for other segments, like from 0-1, 1-2, and 2-3? Be prepared to share your findings with the rest of the class.

4. We shall watch and discuss in detail the motion examples presented in: Frames of Reference < https://www.youtube.com/watch?v=bJMYoj4hHqU >. What is your understanding of the statement, “All motion is relative.”
