Digital Science Notebook (DSN)

An entry needed for every class

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.

Each entry should include sentences, data and images.

See the next seven panels:

  1. Normal notes you would take. Information from the board, introductory instructions, etc. Assigned writing.
  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.)

Setting up the google folders for your DSN–digital science notebook.

  • Create a new google folder.
  • Name it your name (given and family) dsn8 1819
  • As in: <richard frazier dsn8 1819>
  • Share the folder with Dr. F (editing). Share with your parents (viewing).
  • Inside this folder, create another folder.
  • Name it <matter>.
  • Inside the matter folder create a document.
  • Name the document file <10 August first DSN and matter continued> This is the document for today. It will be the first entry in your DSN.
  • Put a title and date on the document.
  • Click on the blogpost entry for today. Copy it. Paste it on the document. For example, the link to today’s blogpost is < >
  • At your table check that each group member has set up the DSN folders correctly.

Several ways to complete your DSN entries.

  1. Write on a google doc located in the appropriate folder (motion for now).
  2. Write on an app of your choice and transfer to the google folder–make sure it is readable. The problem with pdf is the difficulty of adding and revising to the entry.
  3. Hand write (MUST BE LEGIBLE) in your paper notebook. Take a photo and upload the photo. Must be dark, large enough, readable, in focus, and oriented for easy reading.
  4. Take notes–handwritten perhaps–edit and enhance these notes in a google doc. This is the most valuable technique but it is also more time consuming.

We will offer time in class to start your DSN. Some students will be able to complete their entries during class at times. All students are expected to have the DSN entry completed by the beginning of the next class.

Regular beginning our class routine:

  1. Mindful moment.
  2. Review DSN entry from previous class. Add and/or amend if necessary.
  3. Examine blogpost/plan for the day. Follow and view links/references when time permits.
  4. Set up your DSN entry for the day. Remember the file name, a title on the document, the active link to the blogpost for the day. Then prepare to complete the 7 items during and after class.

Continue working on the questions from the last class and some new related questions. If you have questions of your own, please pose them for the class.:

A. What happens when a piece of floating ice melts in a container of water?(Many people expected that the water level would rise. Can you explain their reasoning?)(S0me people said that the water would not rise. Do you follow their thinking?)

B. What determines whether something floats or sinks?

C. Determine the density of water. How would you do that? (Hint: Density is the mass of a sample of a substance and volume is the space taken up by the same sample. Mass is measured on a balance and volume of a liquid can be measured in a measuring cylinder. Ask if you need clarification on the technique.) Discuss with your group.

Enter data on the class spreadsheet:

E. What happens to the mass of a cube of ice when it melts? What is your explanation for what you expect? Discuss with your group. Make notes of your ideas. Test your ideas. Ask if you would like to discuss the technique. There are some aspects that can affect the results.

Enter data on the class spreadsheet:

F. How could we relate the question about ice floating to icebergs? The icebergs that calve from glaciers are fresh water. If they fall into the ocean, they are floating in salt water. How salty is the sea? Are some ares of the oceans saltier than others? What can you find out. Discuss with your group. Will a piece of fresh water ice float differently in saltwater than in fresh water? What do you expect and can you explain your thinking? Can you test your ideas? Be sure to careful make note of what you do and what results you observe.

G. Here is an old puzzle? Which melts faster: An ice cube in salt water or an ice cube in fresh water. Of course, the ice cubes would need to be the same mass, volume, and shape, and the container of salt water would need to be the same temperature as the container of fresh water. Try to conduct a fair test of your ideas?

H. What about the density of salt water? How could you determine the value? Do you think the concentration of salt water would affect the density? How might you express how salty a sample of salt water is?

I. What other questions about water occur to you? Any thoughts about evaporation for example?

J. Here is a very nice essay about water by the science writer Natalie Angier. What do you think. Read it and write a response. Is there anything in the article that sheds light for you about the questions we have been investigating?
