    Step 1  Take 3 pieces of P11 and 3 pieces of CT3, and assemble them
                                     as shown in the figure.

                                          P11      3 pcs                 CT3     3 pcs

                        Step 2  Put your finger in between its claws
                                     and operate it.

                      Output

                      In the plier activity, when you press the handles of the pliers, the jaws

                      (the front part) come together and can hold or grab an object tightly.
                      When you release the handles, the jaws open back up.

                      Concepts

                         • How Pliers Work: Students will understand that pliers are a simple
                         tool  made  up  of  two  handles  and  two  jaws.  When  you  squeeze  the

                         handles, the jaws close and can grab or hold things. This helps students

                         understand the idea of force and movement.

                         • Using Tools for Gripping: Pliers help us grab and hold things tightly,
                         which is useful when our hands can’t do the job as easily, like holding

                         small objects or wires.

                      Observations

                      In  the  plier  activity,  students  will  notice  that  when  they  squeeze  the
                      handles, the jaws close and hold something. When they stop squeezing, the

                      jaws open up again. This shows how tools like pliers use simple motions to
                      help us grab things more easily and with more strength. They will observe

                      how pressing the handles gives them control over holding objects securely.

                      Understanding the Pulley System

                      A pulley  system  is a  simple  machine  made  of  a  wheel  with  a  rope  or

                      chain wrapped around it. It helps us lift or move heavy objects easily by
