Year 5

Rotation Activities

Introduce Simple Machines & Scientific Forces

In this second UOI- How the World Works, we are learning that people apply their understanding of scientific forces to create and solve problems. We are also focusing on the scientific forces, the scientific concept of work, how simple machines work and improve our daily lives, and the design and development stages! At the end of this unit, we are planning to make a model made out of various materials involving simple machine principles that help or solve a problem! We also learned that some sort of simple machine or complex machine has at least one scientific force that applies to it, which helps the machine work as intended!

The Year 5 class is divided into 3 groups when the rotation activity starts. There are also 3 stations; we learned about and discussed simple machines and scientific forces in each station. The 9 scientific forces we learned about are gravitational force ,tension force, magnetic force, frictional force, normal force, applied force, spring force, electrical force, and air resistance force!

School Tour to Explore Simple Machines Applied

Introduction

My name is Faiqa from Year 5A and I will be showing you Year 5’s experience and findings about simple machines while touring the school.

What we did

In the afternoon, we were learning about simple machines that were scattered around the school. We learnt about 6 simple machines that are used in daily life. Inclined planes, wheels and axles, pulleys, screws, wedges, and levers. After we learnt about the 6 simple machines, we were teamed up into groups. We were told to explore the primary basketball court, big playground, small playground, primary plaza and find the 6 simple machines from each area that we explored. We had to write what we saw in terms of simple machines.

After we explored the big playground, small playground, primary plaza, and the basketball court, we went back to the classroom and shared our findings. Each group found a lot of different simple machines, and I’m sure there were still a lot more! After each group shared what they found, we explained what was the function of each simple machine. Each simple machine had different functions. Inclined planes, screws, pulleys, levers, wedges, wheels and axles each had different functions. If we combine more than one simple machine into one machine, then it would be called a complex machine.

Reflection

I would proudly say that each group from Year 5 has found a lot of simple machines, but I think we could’ve explained more in detail. Though, I think we did a very good job. (Faiqa Maury)

Workshop: Experience carpentry activities with Pak Haris

(GJS maintenance staff)

Hi! Our names are Almeera and Aurora from 5A and we are showing you what we learned with our recent guest speaker, Pak Harris. He taught us about complex machines.

In the workshop, Pak Haris taught us about complex machines and how they work. The machines were all used with friction force. He taught us about the function and the purpose of the machines he used. Friction Force is when two objects rub together and it generates heat. Friction Force can slow down moving objects.

He showed us how we can use complex machines in our daily lives and how they’re important. Like how chainsaws cut down trees so that we can build equipment and furniture. We see these things in our daily lives. Bicycles are a form of transportation and are made of multiple simple machines, therefore becoming a complex machine. Complex machines are machines that are made up of multiple simple machines. Friction can be used in the most simplest way, such as holding an object because the frictional force makes it so that it doesn’t fall down. Thank you Pak Haris for sharing your knowledge and skills with us. (Almeera Cahya Arundhati and Aurora Marzo )

DUFAN TRIP

How the world works - UOI 2

In UOI 2, we learned about how the world works; The world is filled with simple and complex machines, and we use them in our daily lives. The world is made from billions of simple machines.

Why did we go to Dufan?

In Dufan, our assignment was for students to observe the types of simple machines used in daily life. We identified what simple machines can be used in a specific scenario. We also analyzed the scientific forces applied in those rides.

What we did

In Dufan, we rode multiple rides as a bonus, and we observed the scientific forces of the rides, simple machines applied and how it works and how they function.

We analyzed how simple machines can be used and how people applied their understanding of scientific forces to create devices in that amusement park. We can connect and combine knowledge and skills to use in different situations, in and outside school. (Kira Kirana Yusuf and Ian Henry Newley)
