Testing experiments and learning how to record our results

-
This week Grade 2 continued to do experiments and learn how to record our results. The children learnt how to set out their page with a science procedural, similar to writing down a cooking recipe. They had to include:
A question - e.g. What will happen when you put a coin inside a balloon, tie it up and spin it around?
A prediction
Materials
Method
Result

We tested out whether a racing car will travel faster on a smooth surface such as the classroom floor, or a bumpy surface such as corrugated paper or sand paper. Strangely, our results weren't conclusive. This probably had to do with the level of force each child used to shoot the car off. We tried using a low table a ramp, but there was a gap between the table and the floor which stopped it from going very far on the floor. 


On Friday we designed our own marble run in the class using cardboard tubes, toilet paper rolls, cardboard boxes et cetera. We tested it about 5 times and found that bumpy pieces of tape kept stopping the marble from getting very far. Also, if the angle of the toilet paper rolls wasn't quite right, the marble stopped too. 

So here are some videos and photos of what we achieved after of 1.5 hours of designing and working together. It was a great teamwork activity and everyone worked hard.

Unit 2: How the World Works

  Unit 2: How the World Works Central Idea: People use their understanding of natural laws to manipulate objects.  We have had quite a busy first term! During this unit we learned about forces and simple machines! We talked about push and pull, and how machines help up use less force to move an object. In the pictures below we were miming push and pull and our friends had to guess which one we were showing! Can you tell if we are showing push or pull? When learning about simple machines we learned about incline planes. Students designed their own marble mazes out of Legos. Students used their knowledge of incline planes and forces to guide their marble through the maze.  In Japanese students made their own recycles cars and connected it to our learning about wheels and axels! Students worked in teams to create their own Rube Goldberg machines to complete a task. A Rube Goldberg Machine is a complicated machine used to complete a simple task. We were very ambitious with ou...

Grade 2- Blog #13- September 4th- September 6th, 2019 LOOKING BACK Students study a map of the world. Placing our stickers on the places we have explored/ want to explore! More mapping!   Welcome back! I hope that everyone had a nice summer vacation, whether you traveled the world or relaxed here in Osaka with your family! We had a short week this week, as students (and teachers!!) adjusted to being back at school! Still, it was an exciting first three days, as we prepared to start new units in math, English, and Unit of Inquiry, and as we welcomed a new student, Riko, to our class! Going on a listening walk through the school. Listening for different sounds on the sidewalk! For UOI time, students began to develop a sense of  "exploration". We explored the whole school by going on a "Listening Walk", we explored our classroom environment by using a treasure map, and we explored our community by finding out more about one another.

Sharing the planet

 Hello and apologies for the missing blogs recently. I hope you enjoyed the photos on Seesaw at least. This week grade 2 started a new unit of inquiry (UOI) related to the transdisciplinary theme: Sharing the planet .  Our central idea is: People's response to conflict impacts the quality of human life. We spent this week breaking down the words. We started by talking about how people share the planet and how this can be difficult in terms of sharing the resources of the planet.  For e.g. What is conflict? How do we see it in daily life and in the world? What is quality of life? We did an activity about needs and wants and discussed what is absolutely essential for a child to have a good life.  We also talked about peace. Is peace just the absence of war? If I am a child and I don't get 3 meals a day and don't have enough clothes but I live in a rich country like Australia, am I really living a peaceful life? On Thursday we watched a short animation about Sadako Sas...
