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
