How to Make a DIY Cardboard Robot
Step 1: Draw the Robot
Use a pencil to draw the robot’s body and head on the cardboard sheet.
Children can create any robot style they like. Creativity is an important part of Grade 3 STEM activities.
Step 2: Cut Out the Shape
Carefully cut the robot shape using scissors.
Adult supervision may be helpful for younger children during this step.
Step 3: Create the Robot Eyes
Draw two circles where the robot’s eyes will be placed.
Cut out the circles so the LEDs can fit inside.
Step 4: Insert the LEDs
Place the LEDs into the eye holes from the back side of the cardboard.
Different LED colors like red or yellow make the DIY Cardboard Robot look more exciting.
Step 5: Connect the Battery
Attach the coin cell battery to the LED terminals.
- Connect the positive side correctly
- Use transparent tape to hold the battery Complete the circuit connection
Science Behind the DIY Cardboard Robot
This Grade 3 STEM activities project also teaches children about electricity.
LED stands for Light Emitting Diode. When electricity flows from the battery through the LED, it produces light.
