Visitors

We had a couple of special guests today: 

Kermit the Frog (and nephew Robin) visit French class. 

This isn't a photo from last year. Summers-Knoll alum Adi's school is off today, so she elected to come visit for the day! 

Separating iron, salt, and sand

As part of an ongoing study of water, filtration, compounds, and mixtures, students are currently working in small groups to design a procedure to separate this:

A mixture of sand, salt, and iron

Into this: 

Separated samples of iron, salt, and sand

It requires a deepening understanding of many of the concepts we've been working with this year, including filtration, mixtures, and evaporation. It also requires brainstorming a plan with their partners, as well as crafting a detailed procedure to follow.

Scenes from the final week of 2014

Now that the energy and excitement of the play has crested, we have a week left before a well-earned break. The final week in December can often be a tricky one, as people are starting to burst at the seams, but we're still getting a lot done! 

On Monday, the first of our book groups presented to the class, telling us a bit about the characters and themes of Mockingbird, the book they had read. 

Later in the day, Gabe and David gave a presentation teaching us about tiling and tessellation, which included a group activity designed to illustrate what shapes are able to tessellate. (It's difficult to photograph a slideshow in low light, so please know that David is actually pointing out a detail of a tiling, as opposed to just a blob of white light.) 

In Math today, what was meant as a warm-up exercise wound up taking over much of the morning, as kids worked together (using manipulatives, drawings, paper, and white boards) to solve a logic puzzle involving checkers on a board. 

Today was also one of our days for PE, so after working through the morning, they were ready to run off some energy in the afternoon. 

Our class lately. . .

It's been difficult to adequately sum up what's been happening at school lately, as we've been very busy! 



First and foremost, our upcoming school play looms over everything. Rehearsals for Alice have taken over this week, and things have been coming together nicely! 

A full dress rehearsal underway in the atrium

Meanwhile, the students who aren't in the play are working on a variety of other projects. 

Gabe and David are working on a tessellation presentation. Marcellin and Keira are working on creating a fraction game. 

Owen began working on an S-K themed newspaper, and Oliver has started contributing as well. 

Meanwhile, our entire class continues our investigation into water, water purity, and filtration. Here, Sam uses a student-built filter to see if it can remove green food coloring from a cup of water. (It can't! Why not?)

Nick shows off a jar of water that has been driving a lot of our investigations. It was pulled from the standing water just behind the S-K playground. We've been watching as it settles and changes, and learning about the processes that cause the jar to re-pressurize every time we open it and re-seal it. 

We've also been conducting an experiment in evaporation. We placed the same amount of water into differently shaped containers. At what rate will each evaporate? (If they're different rates, why might that be?) Not only is it an exercise in surface area, evaporation, and filtration, but also one involving experimental design and good data collection. (Students are also writing a set of procedures that are precise enough that someone else could replicate the experiment.) 

On top of this, we're also continuing with our book groups. Some groups are finished with their books and have moved onto preparing presentations to share with the rest of the class. It's a busy time!
