Lever Centers

Science: I can explore and test simple machines; I can use scientific vocabulary; I can record my observations.

Today, we were learning about levers and there were three stations. Each centre focused on one of the classes of levers. First class levers have the fulcrum in the middle, second class have the load in the middle and the third class levers have the effort in the middle. 

Some examples of first class levers are: seesaw, crowbar, scale, scissors, binder clip
Some examples of second class levers are: nutcracker, stapler, wheelbarrow
Some examples of third class levers are: tongs, rake, tweezers

"I learned how to use tongs and how to use different types of levers in different ways." ~ Enzo
"I learned what first, second, and third class levers are." ~ Liam
"I think we did this to test out first, second, and third class levers." ~ Callie
"I learned that there are a lot of levers in our world and they look very different from one another." ~ Sebastian K
"I think the reason we did the centres was to test different levers rather than learning on paper."~ Leo
"Over the time that we've been learning about levers, I've learned that not every lever is like a Minecraft lever." ~ Vance

Here we tested how much effort we needed to use if we moved where the fulcrum was.
The closer the fulcrum is to the load, the EASIER it is.

Here we were testing picking up the dominoes with tongs.
The closer to the load you pinch the tweezers, the EASIER it is.

Summer Solstice

  SS: I can appreciate oral stories and how they teach us about Indigenous People and life lessons Art: I can experiment with different media Oki ! Happy Summer Solstice and National Indigenous Peoples Day! We learned about local Indigenous cultures and their Summer Solstice celebrations today in a few ways.  We started our day by learning about Natoosi (the sun, in Blackfoot) from Elder Saa'kokoto online. We listened to the Chickadee Story from Chantelle (Metis) online and participated in the Summer Solstice song gifted to the CBE by the Metis people.  We also worked on learning how to braid (either a basic 3-strand braid or an advanced 6-strand braid). This relates to the documentary we watched a few months ago called, Braves Wear Braids (click here, if you'd like to watch it at home) .  Yesterday, we also watched a clip from a documentary by Ryan Heavy Head (a knowledge keeper from Lethbridge). This was teaching us about animal behaviour during the Flower Moon phase. We he

Ralph Klein Park Field Trip Recount

  We had a fabulous day yesterday at Ralph Klein Park. The weather was outstanding and the surroundings were beautiful. We had top-notch programming led by Chelsea from the City of Calgary. Here are some highlights of our learning and photos of the day. In the morning, Chelsea asked us to tell her what a wetland is, what the parts of a wetland are (there are submerged plants, emerged plants and floating plants), and which different wetlands are found in Alberta (marsh, swamp, fen, bog). Some of this was review of what we learned in the fall and some was new information. Then, we played a game where we had wetland creatures taped to our backs and we had to ask Yes-No questions to figure out who we were.  That led us to talking about specific wetland invertebrates and their interesting adaptations. We played a simile game where we had items in a bag that were like a creature. We had to figure out what each item represented and share that with the class.  A box of wood chips and leaves i

The Grade 4 students are completing an assignment called " The Me to Be ". The instructions and hand out are posted in the Google Classroom for reference.  Grade 4s, this is a reminder that you may want to ask your parents for help remembering back to what you were like in Grade 1. You may also want to gather materials to bring in for your collage.  We will be working on them Monday . Please come prepared to work on your collage then. I'll have glue, scissors, and paper ready. :)     Grade 5 students have a crossword puzzle for homework that must be completed WITH a trusted adult. This is to help build their support network for who they can ask Puberty-related questions to. This homework is due Friday, June 17 .
