Light and Shadow Experiments


Science: I can record observations in a clear and organized way. I can discover and explain the predictability of light and shadows. I can observe and connect with nature.
Math: I can measure accurately.

Yesterday, we explored light and shadows in a few different ways. One way we experimented was by drawing a chalk outline of our shadows on the compound. We used our Measurement skills to observe how they changed throughout the day.

"I was surprised to know that some of the shadows were the same as us. For example, if you put your hand on your head, it was reflected in your shadow." ~ Iggy
"The shadow started to grow smaller and smaller as we were working because the sun started growing higher and higher in the sky." ~ Vance
"One time, I wasn't moving and then all of a sudden, my shadow moved. I was trying to get back into the exact pose where the chalk was but it didn't work because it was different because the sun was moving." ~ Seb C
"It didn't surprise me that the shadows were long but what surprised me was that they were very skinny. I think it's because of the angle of the sun." ~ Hazel
"I was right that early in the morning they were longer." ~ Seb K


Here is how we kept track of our observations in an organized way. Ms Elder encouraged us to come back this weekend in the evening (like, around 5:30 or 6:00 pm) to see how are shadows have changed. 


Next, we explored some light and shadows centres. One centre taught us how to tell which way the earth spins by using a flashlight and a globe. Another centre had prisms for us to see light refracting. Ms Elder led a third centre where she read us a story where she projected the picture of the book as a shadow on the ceiling. We learned how shadows change as you move the light closer or further away from the book, or side-to-side. We also learned some light vocabulary: opaque, transluscent, and transparent. 

Here are two videos we watched to learn about light:

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 .
