PYP 5 Unit of Inquiry

Young Inventors Day!

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


Assessment task:

“Simple machines investigator” project


  1. Identify tools/ invention that use simple machine principles in your surrounding (school, home, garage, bed room, bath room, living room, kitchen, play ground, etc)
  2. Explain the simple machine principles used by the tools
  3. Explain how the simple machines principle work
  4. Take a picture/ provide pictures (give students choices) of the found tools
  5. Present the findings in the form of free presentation (PPT, Prezi, visual arts presentation, etc)

 Guided questions:

  1. What objects did you find?
  2. What type of simple machine is it? If your object is made up of more than one simple machine, list all of them
  3. How can you tell what simple machine your object is?
  4. How does this simple machine make the work easier?
  5. 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!

1. Provocation

Task: Give students some challenges to be solved. Ask them to solve the problem without using any equipment
Aim: Students are able to come up with the idea that we need simple machine to make our work easier

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


2. Finding tools around the class

Finding tools around the class that use simple machines principles

3. Brainstorming Simple Machines

Brainstorming students prior knowledge about simple machines

4. Favorite Inventors

Students drew their favorite inventors

Young Inventors Day (1)

Summative day! Young Inventors day!

Young Inventors Day (2)

Young inventors day! Students diplayed and exhibited their inventions and innovations
