PYP 5 students are learning about simple machines principles used in an invention. They also inquire more into the use of scientific methodology to conduct an experiment and a trial and error to modify/ create an invention.
WALT (What I am learning to): To know the principles of simple machines used in an invention
WILF (What I am looking for):
- Define what simple machine is
- Identify types of simple machines
- Explain the simple machines principles
- Identify familiar invented tools which use principles of simple machines
- Mentions some examples of problems that can be solved using simple machines (functions of simple machines)
- Analyze reasons why we use the simple machines in everyday life
First Assessment Task
“Simple machines investigator” project
- Identify tools/ invention that use simple machine principles in your surrounding (school, home, garage, bed room, bath room, living room, kitchen, play ground, etc)
- Explain the simple machine principles used by the tools
- Explain how the simple machines principle work
- Take a picture/ provide pictures (give students choices) of the found tools
- Present the findings in the form of free presentation (PPT, Prezi, visual arts presentation, etc)
- What objects did you find?
- What type of simple machine is it? If your object is made up of more than one simple machine, list all of them
- How can you tell what simple machine your object is?
- How does this simple machine make the work easier?
- There is always a trade-off of effort with simple machines. Explain what you’re trading off to get the job done more easily with this simple machine.
I found out that clock uses simple machine principle to work. The clock tells time by using gears. The gears turn the energy of the clock’s wind up motor into movement, which controls the minute and hour hands.
Below some of the snapshots of their learning!
Activity 1: Give students a piece of a thick box and ask them to cut into pieces without using scissors and cutter.
Activity 2: Put something (not heavy object) at the ceiling and ask them to take without using chairs and table
Activity 3: Use any tool to lift up something heavy
Activity 4: Pick something up from a distance using a tool
