Grade 3 STEM Activities: 3D Pen Drawing Project for Kids
Grade 3 STEM activities help children explore creativity, science, technology, engineering, and design through practical learning. STEM stands for Science, Technology, Engineering, and Mathematics, and these activities encourage children to think creatively and solve problems through hands-on experiments.
In this exciting Grade 3 STEM activities project, children learn how to use a 3D pen to create drawings and simple 3D models using melted plastic instead of traditional ink.
This beginner STEM project introduces students to:
- 3D pen technology
- Plastic extrusion
- Creative design
- 3D modeling basics
- Engineering creativity
- Hands-on STEM learning
The activity makes learning fun while helping children understand modern creative technology.
What is a 3D Pen?
A 3D pen is a special drawing pen that uses heated plastic instead of ink.
The pen works by:
- Heating plastic material
- Melting the plastic
- Pushing melted plastic through a nozzle
- Creating shapes and designs
Unlike normal pens, a 3D pen can create both:
- 2D drawings
- 3D models
This Grade 3 STEM activities project helps children explore creativity and engineering together.
How Does a 3D Pen Work?
The 3D pen uses a process called plastic extrusion.
The plastic inside the pen melts because of heat and comes out through the nozzle in a controlled way.
After the plastic cools:
- It becomes hard
- The shape stays fixed
- The model becomes stable
Children learn how heating and cooling affect materials in real-world technology.
Important Safety Rules
Safety is very important during this Grade 3 STEM activities project.
Do Not Touch the Nozzle
The nozzle becomes extremely hot while the pen is working.
Children should:
- Avoid touching the nozzle
- Use the pen carefully
- Work under adult supervision
Let the Plastic Cool
After drawing:
- Wait for the plastic to cool
- Allow the model to harden
- Handle the design carefully
This helps the model become strong and stable.
Materials Needed
This STEM activity requires:
- 3D pen
- Plastic filament
- Drawing sheet or surface
- Adult supervision
These simple materials help children explore engineering and creativity safely.
Simple 3D Pen Activity for Kids
Step 1: Turn ON the 3D Pen
Switch on the pen and wait for it to heat up.
Step 2: Insert Plastic Filament
Place the plastic filament into the pen.
The plastic starts melting inside the pen.
Step 3: Start Drawing
Press the button gently and draw shapes slowly.
Children can create:
- Stars
- Squares
- Animals
- Flowers
- Names and letters
Step 4: Let the Plastic Cool
Wait for the plastic design to cool and harden.
The shape becomes stable after cooling.
