Science: "Enigma Cylinders" (and banana phones)



As you may know, Lisa Johnson (famous and beloved for bringing Fish Lab to Summers-Knoll) has joined our faculty as a science teacher. We'll be co-teaching science this year, and we ran a fantastic activity on class on Monday. I'll tell you all about it, just as soon as Bora finishes this phone call.

We wanted the kids to get the kids "doing science" early and often this year, but many people have differing ideas about what that actually means. To get us all thinking about what science really is, we introduced the class to some mysterious objects that we call "Enigma Cylinders." 



As an educator, this activity was incredibly easy to run: We simply passed out a few of the cylinders to the kids. Before we had a chance to bore them with directions, they all instantly snapped into the mindset of scientists. They furrowed their brows, tugged at strings, and started talking. 





First they made observations, then they started offering possible explanations for what they were seeing. Before long, they were sketching. By the time Lisa and I actually told them that they'd be attempting to make their own models of this contraption, most of them were already well on their way to sketching potential designs. All of this was pure inquiry. It required so little direction from us that I was able to film them in action. Check out the following video, which picks up immediately after handing kids the cylinders. None of what you hear them saying is in response to questions that we've posed to them. If you've ever wanted to be a fly on the wall during a Summers-Knoll class, this is the video for you:


As mentioned in the video, all three groups eventually constructed models that seemed to be reasonable facsimiles of the cylinders that they examined. However, Lisa and I have vowed to never reveal the inner workings of our actual cylinders, as that's part of true science! There are many things in this universe that we will never truly know. 



Lisa gave a great example: We will never know for certain what caused the extinction of the dinosaurs. Never! We do, however, have a very good hypothesis or two about what happened to them. And as we collectively learn more about the world, we can revise our hypothesis (or throw it out entirely if compelling evidence demands it). In many ways, science demands failure and revision. We will encourage both over the course of this school year (and beyond)!




But enough about Science. Let's check in with Bora. How's that phone call going, Bora? 


See? This is why we make kids keep them in their backpacks.

Trip to the University of Michigan Chemical Engineering


On Tuesday, we took a field trip to the North Campus of the University of Michigan to check out some interesting things in the Chemical Engineering labs. 

As part of a Senior-level Chemical Engineering course, U of M students require colonies of algae, which are used in designs to generate biodiesel fuel.  



We learned where the algae comes from (a small sample is purchased from the University of Texas), how its grown, and what's done with it by the students. 

Each of these tubes is full of bubbling algae.

Here's a very brief video to give you a sense of what it looked like in action: 






We also took a quick visit to the Wave Field




A huge THANK YOU to Christine Moellering for arranging this tour for us!

(And if you have an idea for a tour destination idea, get in touch!)

January So Far...

January is off to a rollicking good start in the 5/6. (Snow Days excluded, or perhaps enjoyed.) Here's a long, rambling recap of some of the things we've done with these first eight days of January.
A quiet work period in the middle of a very busy two weeks. 



Evan explains the ideas supporting the exploration of Near Earth Asteroids (NEAs).

This month has a strong science and social studies focus. Our new school theme is Journeys, and we're exploring that by beginning a unit on manned exploration of space.

Last week, the students split up into small groups to learn about a possible destination for a human habitat outside of the atmosphere. The groups each read an article about the logistics of putting people in one of the following places: Low-Earth Orbit, Near-Earth Asteroids,  Luna (Earth's moon), Venus, or Mars. (Ask your student about the destination that they researched!)

Marcellin and a guest student explain a proposed mission to Venus. 

Prior to presenting, each student had a specific role in their group: The Data Specialist was responsible for making notes on the key points in the document. The Mission Commander was responsible for presenting the groups report to the whole class. The other students in the group were given mini-rubrics to help the Mission Commander prepare the short presentation, as well as being responsible for the initial reporting.

Each group then presented a summary of what they learned to the rest of the class.

This week, science has been focused on the wide variety of technologies that have been developed or enhanced as a result of Space Exploration (Insulin pumps! Whale tracking technology! Helmet padding!) . Each student is investigating two specific NASA created (or developed) technologies.



In math, we are doing a small project on data collection, display, and analysis. So far the students have crafted questions suitable for analysis ("What month were you born in?" "How tall are you in inches?").

Today we talked about how to collect and organize the data as it's being collected, and then moved on to actual data collection. A few students have begun to transfer their data to a Google Sheet (the spreadsheet program in Google Drive). Next week, we'll be working on analyzing and presenting the data and making conclusions.

Owen collects data about student's favorite sport to play.

We've also wrapped up our book group presentations. As mentioned in a previous post, we've been reading novels in small groups. Each group has completed their book and prepared a presentation for the rest of the class to share about the book and their experiences. Some groups spoke in the first person as characters from the book, some read excerpts, and everyone gave enticing summaries about what was valuable and interesting about each book that they read.

Niko reads a selection from A Wizard of Earthsea, as Marcellin, Luke, David, and Owen await their turns to share. 

We've also been having some group discussions about the media, society, and how we interact with each other. On Monday, we wanted to gauge how kids were processing anything that they may have heard in the news about various terrorist acts. Students' awareness of the news stories varied widely, which lead to a productive discussion about how we consume media, and why certain stories stick out in our minds. For example, of all the current events that were mentioned, the only one that almost every student had heard of was the semi truck full of fireworks that was involved in an accident on I-94. We talked a little about why that story has stuck out in their minds. ("It's sort of scary." "It's exciting.") We eventually hit on the idea of personal relevance and/proximity: Something happened that feels close to you. Car accidents on I-94 feel much more relevant than car accidents in Nevada.


We eventually also talked a little bit about the incidents in France recently, trying parse through the rationale for such a senseless act. We talked about the concept of satire, fundamentalism, freedom of the press, and the challenges (and strengths) of living in blended, multicultural societies.

Finally, we had a long sprawling conversation yesterday about our personal interactions at school. We frequently have these kinds of discussions on a small scale, sometimes in response to a specific conversation, and other times preemptively, but yesterday's chat was particularly in depth.

We talked a lot about how to navigate the constantly shifting power dynamics of the middle school world. We talked about "being your best self" as often as possible, with the understanding that no one can always achieve that. However, if one of us happens to fall short on a given day or in a particular moment, as long as the rest of us hold ourselves together, things will be okay. We also talked about how to prevent situations from spiraling out control, not carrying the grudges of other people, and strategies to help things run smoothly during these occasionally turbulent pre-teen years.


This is a spotty snapshot of some of the things that were discussed. We'll be revisiting this conversation regularly in the weeks and months ahead.


Oh, one more item worthy of note:

In writing last week, we went over the rules of using quotation marks when writing dialogue in stories. As practice in this, kids were required to write a dialogue between three or four characters using proper punctuation. The dialogue did not have to be a self-contained story, but it did have to give some sense of what the larger plot was, where the setting was, and a bit about the personalities of the characters involved. They are still trickling in, as they're not formally due until tomorrow (Friday), but on the whole, they've been both excellent and hilarious. Since the assignment only asked for a scene, many kids seemed content to come up with some bizarre and creative ideas. Nearly everyone of them is a cliffhanger begging for the larger context of the unwritten story. They're great.

On a whim, we staged a few of them as impromptu mini-plays in class the other day, much to the delight of everyone.

Stream table workshop at the University of Michigan Museum of Natural History


On Thursday, we visited the University of Michigan Museum of Natural History for a stream table workshop. We built and tested filters in small groups (and using different materials than our classroom filters), and spent time exploring a large stream table. We used it to observe water flow and erosion, and experimented with methods of curbing it.








The greenish tint to the right of this tiny ranch is food coloring, which represents agricultural waste. When the water starts flowing, it quickly finds its way into the river.

After our workshop, we spent some time exploring the museum in small groups. Everyone found plenty of things to investigate.

Comparing the the DNA of humans and chimps. It's amazingly similar.

Science: Filtration investigation

Various filter designs

As part of our ongoing study of water, watersheds, and water quality, we began a discussion today about water filtration.


We began with a reading to build some background knowledge, making note of (and discussing) terms that were unfamiliar to the class.

Then, students were tasked with creating two different designs for potential water filters, given a list of materials and their costs. Their budget was $8.00 per filter.



The groups set to work, brainstorming ideas and crafting designs.






The next step will be to present their designs to the class to get feedback.
