18 October Science 8 Getting ready for WOW–Water and Rivers

  1. Mindful moment. “We Wash Our Bowls” by Gary Snyder–

2. Check previous DSN. Make sure your data is entered on previous spreadsheets. Make sure you have reviewed and reflected on all experiments and all data. (Look at 1718 data, too)

We will have an interruption in our study of chemical reactions, so it is very important that you KEEP IN VIEW the ideas we have been discussing and exploring.

3. See today’s blogpost and plan.

4. Create DSN entry in a new folder called Earth Cycles. Put all your notes and writing from today in this folder.

5. Questions.

  • * * * * *

Write a reflective response to the poem. It is about Water (of course) and has references and vocabulary related to rafting intertwined. It also has references to Asia and Asian landscapes. What does the poet suggest about the relation of water to landscape? What are the different ways the poet alludes to the significance of water?

What is your experience with rivers? Describe the different rivers you have known?

What do you anticipate about rafting on the Ganges during WOW 8? Do you know where you will be rafting? sleeping? eating? hanging out?

What are the properties of water–at many scales? How do these properties determine the behavior and interaction of water with us? with the physical earth? with the living earth? with the entire earth system?

What do you think the opening epigraph means: “The 1.5 billion cubic kilometers of water on the earth are split by photosynthesis and reconstituted once every two million years or so.” ?

Explore these maps and aerial photographs:

AES

Questions: What part of Delhi is AES in? What part of India is AES in?

Our train

Question: How does it compare to other trains you’ve taken?

New Delhi Railway Station

Question: Can you find the likely route from AES to the New Delhi Railway Station?

The route

Questions:

How long in kilometers do you estimate the train ride to be? In which stations/cities/towns do you think the train will stop?

At one point on the trip the train changes directions—if you were facing forward you will now face backwards and vice versa. Can you find the place where you think this will happen?

Zoom along the route—farmland

Photo from the train

Questions:

What crops can you identify? What do you see people doing in the fields? What farm products do you see being transported on the roads? Do you have any connection with these products? You might be very fond of the crop being harvested in the picture. Any guesses?

What wild and or domesticated animals do you expect to see along the way?

From Haridwar to Rishikesh

Notice the terrain changes from Haridwar into the foothills. What do you think the different colors on the map mean? What do you think the lines mean? <http://s.hswstatic.com/gif/how-to-read-topographic-map-2.jpg>. The high Himalaya are not shown on this section of map. How much higher do you think they get? Look at the segment of the Ganges shown. What direction is it flowing (of course it is flowing downhill), but what compass direction does it flow from point to point along the portion that is shown? Why do you think that happens? 8th graders will raft much of the section of river that you see in the map. Find out about the term: Watershed.

 

 

 

Look at the aerial photo and try to trace the river down stream. Rapids are named on some of the areas when you zoom to a certain scale.

This link is to a very nice booklet on river dynamics for rafting:

The booklet also appears at this link but is not so convenient as the pdf version:
