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 this system to distinguish different tools used in daily life and whether they were actually a lever system or not. Besides that, students also learnt to determine if the lever system is saving force or not by comparing the distance of the loading arm and effort arm.

Student's Reflection
I learnt that there are different types of lever systems and I could identify if they were saving force or not. The lever system is highly related to our daily life, and there are so many examples in daily life, such as the door, the kitchen tongs we use in a bread shop, etc. I enjoyed learning this topic mostly by coming to understand how a lever system works and what components it contains. The lever system is very useful, and it can help many people in their daily lives. I would like to learn more useful, everyday examples related to the lever system and all the different methods in using them.
Teacher's Comment
Daisy showed great effort in her work. Her notes were neat and she took the initiative to write them down to better help her own understanding in this topic. She correctly identified the three main components in different daily tools and whether a lever system is saving force or not in her work. Daisy showed great curiosity in her learning, as she mentioned that she would like to know more and more daily tools that are related to a lever system. Well done, Daisy! Continue your great curiosity to explore and understand more of all the amazing wonders in the scientific world.
