On Monday, we will access this padlet to share the knowledge we have built so far about The Properties of Air and about Flight! https://padlet.com/mfawcett/nknyeru2gips
(This blogpost is in progress ~~ check back later, too!)
We watched a short Bill Nye the Science Guy video about Structures. We added words and ideas to our anchor charts. We took a closer look at arch construction.
We tried (without much luck) to adjust the shape of cheese cubes in order to recreate the cheese arch from the video , despite Stephanie being a fine “cheese-mason”! We’ll leave the materials out for some brave soul to keep trying this arch!
We took new information from the video to incorporate into our K’nex structures exploration.
Owen C: As the structure got bigger it need more support. Small red support piers to the base
Emma: The base is an octagon. The top will be an octagon too so it will be an octagonal prism.
Rebecca: It has (vertical) support beams (piers).
Connor: The red piece is the main connector. The yellow supports make the structure more stable.
Kai N: This is a monster truck punch-buggy. It is strong because it is a dome shape. It is stable because the base is wide.
Iris: We used triangles because they are one of the strongest shapes.
Ms Fawcett: Do you think all triangle types are equally strong? Would you modify the materials for different triangles?
Iris: Scalene triangles would be the strongest (symmetrical) — sides could carry an equal load.
Mark: On a scalene triangle one side would be able to carry less load than the other side. You would make the weaker side out of stronger materials.
Owen C takes safety to the next level: “We’re constructors and engineers – we have to wear helmets on site.”
Elliot: a rectangular prism is stable lying on its side with a wide base.
Taylor & Kailyn: The square base is stable. How tall it is makes it a little unstable. To make it more stable we could have an arch or build a triangle shape support on the side.
Material/budget issue: Lack of materials! Interesting conversations happening:
“Do you have another red piece we can have?”.
“What are you willing to trade? Do you have any of these?”
“What is it you desire?”
“No stealing any.”
“I’m going to see who needs white”
“I decided that my job is to organize what we have and decide what we can trade. We decided to trade instead of give. We can give away some things too.”
Counting and protecting what we need; offering what we can share. Do you think there is a connection in the real world of construction (needs, shortages, having extra materials, connecting with other builders/companies)?
In Mr. Obermeyer’s class, they are building structures. What is working well with this structure? What needs to be changed or added in their design?
We consulted with Mr. Obermeyer on our cheese arch. Why do Mr. O’s arches work? How did he modify our design?
Eric successfully follows Mr. O’s design and it works again!
Students worked on answering the questions from above:
1. How could Mr O’s students newspaper structure be improved to be more stable? What did they do well?
2. How did Mr O modify our cheese arch design to make it work?
Students also generated questions for further inquiry ~~
1. Why does salt melt ice? What exactly happens with the salt and water molecules?
2. How exactly does condensation take moisture out of the air? What happens with the molecules?
3. Why is gas that goes in the car look like a liquid when I see it spill?
4. Are all gases invisible?
5. Why does water take up more space in its solid (ice) form than it does in its liquid form?

As usual, Rousseau is participating in the annual Ancaster Community Food Drive. We will be collecting food in 5F for seven days (in all classes K-6) — please consider donating what you can for our families in need. According to the Ancaster Community Services, the need in Ancaster increases every year. The largest growing demographic of families in need is single parent families, and together with helping seniors in need and many other families, the Ancaster Community Food Drive has never been more important.
So excited for school tomorrow! Minus the ice & milk and blowdryer (which are either in the fridge/freezer or necessary for my morning routine!), I’m all packed for what I need to bring for students for tomorrow! They will be bringing supplies as well, and are armed with their materials list/procedures/hypothesis for their experiments! Not sure what all the students will be investigating, but by all the requests for ice, milk & salt from 6 groups, it doesn’t take a rocket scientist to infer that it may be a delicious day. Lots of other experiments happening, too, as we consolidate our learning about solids, liquids & gases.
We collaborated on our list of “needs” using a Whole-class Google Doc — fun!
Students worked in groups with line graphs, and we will be able to extend our learning to include bias: Interesting how choosing different scales cause each of these data to look so different when graphed!
