STEM Task – Constructing machines

We tried our hand at some construction tasks this week. While looking at Ancient Wonders of the World Grade 2 and 3 discussed how they were able to lift heavy loads without the electricity and machines we have today. We then attempted to create our own crane after looking at some pictures. We had mixed success but enjoyed the process and look forward to trying again. Grade 4 and 5 specifically looked at the Hanging Gardens of Babylon and how they moved water as it was located in the desert. We experimented and created our own chain pumps to move water, which is what they would have used back then. Most of them worked.

Landforms

We have started our Science unit by looking at landforms. We watched a video about landforms and then did a landform scavenger hunt where we had to match the picture to the definition.

 

 

 

 

 

 

 

 

 

 

 

 

In pairs we each took two landforms and created an example out of clay.

 

 

 

 

 

 

 

 

 

Here are our final pieces.

Grade 5 Science – Maddy

This week in science Grade 5 have been working on physical and chemical reactions. We did tons of experiments and then we had to identify if it was a physical or chemical change. For example we did origami. We folded the origami into a dog shape and we found that it was a physical change because the paper didn’t change color or smell it just changed shape so it was still paper!

Adaptations – Jimi

This week grade 4 has being working on a story about an animal and how it used it adaptation to solve problems or create problems. I wrote about an ostrich named Ostry and his adaptation are claws, super speed, wings, and strong legs to jump high.

Adaptations – Avery

This week grade 4 was working on adaptations in science. Adaptations are things animals and plants develop to defend against predators, find food, and withstand heat and cold. An experiment we did was checking how animals in the Arctic withstand the cold. What we did was have a bucket of cold water then we stuck our hands in it for a little bit then took it out and put a plastic bag on our hands and stuck it in. It made me a little less cold but I was still feeling the cold. Finally, we put margarine (to represent fat) in the bag and put our hands in the water. I barely felt anything! Have you done any interesting experiments? If you have comment about them.

Grade 4 Mapping

Grade 4 have been working hard at learning about maps. We looked at the history of mapping and the changes throughout time. Then we looked at the different types of maps and sorted out examples creating a booklet. Finally we followed instructions to create our own maps. See our finished results below.

Grade 4 Science – Earth Models

Grade 4 are looking at forces that change the surface of the Earth. To get an idea of what the Earth is made of and how thin the crust is we built our own models. We then cut them in half and compared them. An observation made was that the crust is uneven around the Earth. We concluded that this meant that the crust is uneven around different parts of the world. We connected this with the thickness of mountains. 

Science – Amarachi

This week in grade 5, we’ve been working on science. We are studying the four spheres of the earth and how they interact with each other. After that, we would choose two spheres and make a model with their interactions on it. The four spheres are the geosphere which means land, rock, hydrosphere which means water, biosphere which means life and atmosphere which means air. My favourite spheres are the hydrosphere and the atmosphere. As we were doing this project, we were also grading ourselves. What are your favourite spheres?
