Task Description
In this topic, students learnt about one of the simple machines -the lever system. They learnt to identify the three basic components of a lever system (load, effort and fulcrum). Students applied the concepts learnt in the lever system to distinguish different tools used in daily life and whether they were a lever system or not. Besides that, students also learnt to determine if the lever system was saving force or not by comparing the distance of the loading arm and effort arm.

Student's Reflection
In this topic, I learnt how to identify effort, fulcrum and load in a lever. I also learnt how to save force by using a lever system too. We can find lots of lever examples in our daily life easily, such scissors, chopsticks, clothes pegs and nutcrackers. I enjoyed the experiment about levers that we did in the lesson the most. It let me know there were different ways to make a lever, such as when loading arm was longer than effort arm, we would need to use more force. I would like to learn more about different types of levers and the ways in using different materials to make them. After learning them, then I can make a lever system more conveniently.
Teacher's Comment
Nicholas showed great effort in his work. He took the initiative by writing down notes to understand more about the different types of lever systems. He showed that he understood the basic lever concepts by identifying the three main components in different daily tools that use a lever system. Also, whether the system saved force or not. And he did all of this correctly in his work. Well done, Nicholas!
