13 August Science 7 Learning about motion! Learning about learning!

Beginning routine and plan for the day:

  1. Mindful moment.
  2. Review entry from DSN from previous class.
  3. Preview blogpost for today.
  4. Set up entry for today’s DSN entry.
  5. Questions.
  6. Share aloud with the class your reflections/questions from your previous DSN entry.
  7. Make a sketch of a bicycle. Take up the page. Write your name on the back. Write your period. Turn in your sketch.
  8. Read these articles <https://www.wired.com/2016/04/can-draw-bikes-memory-definitely-cant/> and <https://creators.vice.com/en_us/article/gvw9pm/bicycle-memory-drawings-renderings>. Take a look at everyone’s sketches. What do you think? Write a response.
  9. Write your story of learning to ride a bicycle. Provide as many details as you can remember. If you have not learned how to ride a bike, tell what you think you would have to do to learn. Be specific.

10. Notice the bikes in the picture. They represent two approaches to learning to ride. In one case balance is mastered first. In the other pedaling is mastered first. Which method do you think is best? Why? Write your ideas.

11. See the map

This is my route biking to school. At the beginning of last week it took me 22 minutes from my door to gate 5. Last Friday I covered the distance in 19 minutes. Work with your group. Using a map, make an estimate of the distance. Then figure out the speed = distance / time in kilometers / hour. What would the speed be in meters / second for the entire trip? Explain your thinking. Show your work.

Here are the streets in order: E 9 / 15 (Vasant Vihar) to small street to Vasant Marg to Poorvi Marg becomes Kama Koti Marg to Tamil Sangham Marg to Major Somnath Marg to Rao Tula Ram Marg becomes Shanti Path to Niti Marg to Satya Marg to Chandragupta Marg to General Jore Artigas Marg to Gate 5.

The “speed” you determine is called “average speed” because it gives a value for the entire trip even though there actually were starts and stops and varying speeds during the trip. Under what conditions do you think speed could be constant? If you made a line graph with distance on the vertical axis and time on the horizontal axis, what do you think constant speed would look like? How would a faster speed look compared to a slower speed? Explain your thinking.

12. Let’s watch The Backwards Bike. This video is about two things–the motion of a bicycle AND learning about motion. Think about what the presenter says carefully. <https://www.youtube.com/watch?v=MFzDaBzBlL0>. If you do not understand something, feel free to watch the video again. Compare the example described by Destin Sandlin to examples of learning / unlearning / confusion / understanding from your own experience in any area.
