Creating Our Own Seasonal Round to Inform Us as Consumers

Coal River Seasonal Round
Two days ago, I was reading a Teaching with the Library of Congress Blog post about Seasonal Rounds. Seasonal Rounds was a term that I wasn't familiar with, but it is a visual that shows the annual pattern in the production of food. The Library of Congress example showing activities around the Coal River in Southern West Virginia goes further to add in community events and other seasonal events like splitting wood or what animals can be hunted at different times of the year.

I found the visual of the Seasonal Round intriguing. It did an exceptional job of showing the never-ending nature of the work that people do with food production. I also thought the suggestions by Danna, the author of the post, for students to look at yearly family activities could be displayed in an interesting way using the visual.

Jefferson's Vegetable Market Chart
This morning, I read a post from the Library of Congress Inside Adams Blog entitled The President and the Parsnip: Thomas Jefferson's Vegetable Market Chart (1801-1808). In the post, I discovered an interesting primary source, a chart of the typical times fruits and vegetables were at market in Washington. The detail of Jefferson's work reminded me of his weather record, a primary source some students had analyzed earlier this year. But the yearly pattern that he was displaying reminded me of the Seasonal Round graphic that I had looked at just the day before.

My first instinct was to wonder what Thomas Jefferson's chart would look like added to the Coal River Seasonal Round. I knew there may be a geographical issue with looking for overlap though. Then I started to think a little closer to home. I thought of local restaurants in St. Louis that tout their locally sourced foods. I thought of the local grocery stores (1, 2, 3) that advertises locally grown produce items available during the spring, summer, and fall. I thought of the seed packets at home that would be opened in the next few weeks to plant my home garden.

I think there is an interesting science connection here that may even tie into an idea of creating traditions, a variation of what was mentioned in the original Seasonal Rounds blog. We have a grade level that plants a garden at RM Captain. The next school year, another group of students harvest the vegetables that were grown. There is some initial knowledge of the growing season imbedded here in student learning. What if we built upon that?

Starting with Jefferson's Vegetable Market Chart, we could analyze the document to learn that different fruits and vegetables were available to Jefferson at different times. Incorporating the seed packets used by the students when planting that contain information on planting times and growing periods, students could bridge their understanding to connect the availability with the growing season of the fruits and vegetables. That would give us a very local start. From there, we could reach out to  local farms to gain more information on local planting and harvest times or grocers on the typical availability of different local produce. We could then look at the seasonal round to see how these producers tracked their information. Ultimately, we could create our own local Seasonal Round to inform us as consumers. Students would know when local fruits and vegetables are typically available.

With a focus on the health & science curriculum that deals with nutrition, we could even push the idea further. We could look at types of meals and recipes that incorporate those locally grown seasonal fruits and vegetables. We may be able to connect with a nearby restaurant that utilizes local produce to see how they make decisions about their food choices with what is available to them locally.

Ultimately, students could utilize a document from the past to launch learning that impacts choices they make in the present and future. At this point, it is still only an idea, so now it is time to get to work!

Taking Notes Like a Scientist: Using Primary Sources to Examine Note Taking Strategies

Last summer, I participated in the Library of Congress Science Seminar, a five day professional development opportunity that allowed me to begin exploring the integration of primary sources as a resource in science instruction. As part of that week, I made a plan on one way to integrate primary sources with the direction to implement the lesson during the first half of the school year.

My idea for a lesson revolved around science note booking and note taking in our school. In 3rd grade, our science teacher introduces the process. It continues through their elementary career. During a book study last year on research, using Chris Lehman’s book “Energize Research Reading and Writing”, I saw many correlations between the free form style that students use when science note booking and the introduction to note taking styles with student choice based on need emphasized in Lehman’s book.

I saw them as two styles that could complement the other. My question was how to bridge the gap between the two. While at the Seminar, I decided primary sources might be the answer. Through the use of primary sources, students could connect their own natural tendencies to organize information through science note booking with tried methods to organize information that scientists have used in the past. Instead of teachers demonstrating note taking methods, students would discover the note taking methods of actual scientists and attempt to incorporate those methods into their own note taking. These methods could transfer into note taking in other subject areas as needs arose.

During the first week of school, third grade students participated in the note booking emersion. They observed fish, plants (and all of the insects on them), and other scientific phenomena. During their excursion, many students saw some type of small eggs on melon leafs in the school garden. This caused a lot of excitement and speculation. The classroom teacher had a naturally generated question and we decided to run with it. Students would do a mini research project trying to answer their question and I would help them think about their note taking in the process.

Students began their study of scientists’ notes by analyzing a page from a notebook of Alexander Graham Bell. Students used a modified version of the Primary Sources Analysis Tool from Library of Congress. For the purposes of this lesson and because of time restrictions, I wanted students to focus in on what they saw as an organizational tool (Observation) and why they thought the scientist organized his information in this way (Reflection). 

Students found a great deal of organizing methods. Pages were numbered, ideas were dated and sorted into short paragraphs. There were drawings of Bell’s telephone that was labeled with letters and those corresponding letters were used in his writing about the device. And in each method, students were able to give some reflection as to the “why” of its use. “Short paragraphs are easier to read.” “If you date things, you’ll know what order you did them in.” “Labeling the picture and using the labels in his writing helps me understand what he is writing about.”

Smaller groups then continued by analyzing another note or recording method of a scientist. Students analyzed the directions for using a macaroni machine written by Thomas Jefferson. They explored the drawings for a crossbow by Leonardo da Vinci. Students even looked at more recent notes by Dave Morrison as he thought about measuring the surface temperature on Mars. 

In these other works, students noticed drawings done from different perspectives, underlined and circled words, tables, step by step directions, and different ideas for the same goal drawn side by side. In each case, students were, again, able to express an idea about why the scientist chose to organize his thinking in that way. “It makes it easier to read.” “This was probably really important.” “You can see different details when he draws it this way.”

We extended the activity by asking students to look at their initial writing and drawing from their note booking experience. Could they see similarities between their work and the work of the scientists? They shared example after example, further reinforcing themselves as scientists and their work as scientific. I also feel they saw the work they do in a school setting existing outside of and beyond school. This skill was important and was used by great minds! Finally, I asked them, “As you take more notes, either from observations or from reading or viewing images, what strategies did these scientists use to organize their information that could help you?” Many shared ideas directly from their findings through the primary source analysis.

As they moved forward with their study, I did revisit their second set of notes and there were definite similarities between their work at the scientists’ work they studied.  My hope is that this has laid a foundation and gives examples to call back to as students continue to explore note taking.


note: For anyone trying something similar, I will share that I did have to make transcripts of much of the notes because of the cursive handwriting. While students were willing to make attempts, the struggle would have slowed down the activity too much.

Heliocentric, Geocentric, and Primary Sources

Yesterday, I had an opportunity to use one of Library of Congress' new eBooks with students. I posted some pictures on Twitter, but wanted to share a little more about the process.

I had been looking for some integration of research skills for our one fifth grade class that is currently studying space and motion. While students had mostly been studying observational aspects to space such as moon phases, their classroom teacher shared that they had been introduced to the terms 'heliocentric' and 'geocentric'.

The new Understanding the Cosmos eBook primary source set gave a great selection of primary sources that could help support that topic. Originally, I thought that I would encourage students to explore the differences within several geocentric models, but upon asking the students a few questions, it became clear that they were still hazy on what these models were and how to define them. Many students thought that it might be the solar system drawn from a different point of view, not necessarily different models of the solar system. Even though this helps explain why these models are different, they hadn't grasped the inherent differences in the models themselves. I hoped that analyzing pieces from this primary source set would help them come to an understanding of the difference.

To prepare, I first downloaded the eBook on a class set of iPads through the iBooks store. There is no charge for the eBooks. (The eBooks are currently only available on iPads, but a recent Tweet implies they are looking at other options.) This only took about 20 minutes for almost 30 iPads. I didn't have the books sync because I didn't know how the sync feature would impact a class of students using the books at once. After downloading, I found the primary sources that had heliocentric and geocentric models of the solar system. (If you're wondering, they are images 5, 6, 8, 11, 12, and 15.) Finally, I had copies of LOC's Primary Source Analysis Tool for the students.

Each student was given a primary source to analyze with no two students analyzing the same source at a table. I projected the eBook on the SmartBoard and showed students how to access the eBook, their primary source, and how to draw on the primary source, modeling some reasons they may annotate on the image. I told students we would work on defining our words, but for now, they were just to analyze their image, taking notes on the paper provided. (I did not use the included analysis scribing in the eBook because I wanted to give students a chance to have all of their writing in front of them at once and because I wanted to see their writing.)

I found that students, for the most part, had a great deal of focus on their analysis. They loved to pinch and zoom feature and used it to see details that couldn't be seen otherwise. They used the draw feature purposefully, circling things that they found interesting, unusual, or important. They used their finger to write "Why?" about some of the writings around the models. While there was sharing with others, it was purposeful. They were engaged. I did have to direct the students to write out reflections and questions on their analysis sheet. They wanted to continue to interact with the primary source and each other. While that engagement is incredible, writing out observations, reflections, and questions on the Primary Source Analysis Tool, in my opinion, helps to focus their attention and allow later conversations with each other to be elevated because they have concrete evidence of their own thinking.

After students analyzed their primary source, I asked them to confer with others at their table. There were two groups that all of these models could be grouped in, heliocentric and geocentric. I suggested they use their analysis and focus on the differences and similarities to try to help them define the words that they could not correctly define earlier.

Students talked with each other about what they noticed in their primary source. Some pointed out that the moon is drawn as a planet. Others noticed that not all of the planets were shown or that the scale was off. They explored the language and how they translated some words to figure out where a planet or the sun was in the model. What I did not expect was for them to talk as much about the language. Sol, Terra, Earthe, Sonne, Solis, Geo- and Helio- were all words that students focused on, talked about, and highlighted.

When the class shared out at the end of the session, all of the groups but one had a correct definition of 'heliocentric' and 'geocentric'. What was interesting to me was that the one group that did not have a correct definition for the terms still used a very logical explanation for their thinking. They believed that one word had to do with models that had gods or other spirits living on the planets of the solar system and the other word defined those models where the planets were barren. As they shared their focus on the images they analyzed, their thinking made great sense. That being said, by the time two groups after them had shared, they asked to change their idea based on what others had said.

This embodies why I appreciate the use of primary sources in learning. Analyzing primary sources as part of an activity encourage the struggle that leads to learning. Students had to observe, interpret, and apply their understanding of these primary sources to create a definition for a pair of words. They brought in their own understanding of the solar system and of language to help construct that understanding. They worked individually and then collaborated together to come to agreed upon meanings that weren't confirmed by the teacher until all had an opportunity to make their own learning journey. Overall, I would consider this a good first experience with using primary sources to explore this topic and a promising first use of Library of Congress' new eBooks.
