Today we combine electronics and motion! We will recall our circuit skills, learn how to build on a breadboard, and create our very own moving vibration robots. Finally, we will see the difference between simple mechanical robots and intelligent AI robots.

We remember how to use the Electronic Snap Circuit kit! Now, we are graduating to real engineer tools. We will use a Breadboard to connect jumper wires, LEDs, and resistors without any soldering.
Focus: Snapping the big Snap Circuit blocks to make the LED light up safely. Feeling the physical connection. Bodily-Kinesthetic
Focus: Learning that Breadboard rows are connected! Pushing jumper wires and LEDs firmly into the holes to complete a circuit.
Focus: Understanding polarity (Anode vs Cathode on an LED). Why we need a resistor to limit current and prevent the LED from burning out.
Fine motor control (placing wires/components):
Understanding of the Breadboard layout:
How does electricity travel? In a Series circuit, electricity walks on one single path. If one bulb breaks, they all go out! In a Parallel circuit, electricity takes multiple paths.
Focus: Watching what happens when the teacher pulls one wire out. Saying "Uh oh, the lights broke!"
Focus: Building both circuits. Noticing that LEDs in Series are dimmer, but LEDs in Parallel are brighter!
Focus: Tracing the flow of electrons. Understanding voltage drops across a series circuit vs consistent voltage across a parallel circuit.
Did the student understand why the parallel lights were brighter?
Time to build! By taking a DC motor and adding an off-center weight (like an eraser or clay), we create intense vibration. We will build a Farmer Robot to push seeds/dirt, and a Doodling Robot that draws with markers!
Focus: Chasing the Doodling robot as it draws messy circles on the paper. Laughing at the chaotic movement. Spatial
Focus: Taping the markers together, mounting the battery pack, and attaching the wires to make it move.
Focus: Adjusting the center of gravity. Moving the weight on the motor shaft to change the diameter of the doodle circles or the speed of the farmer robot.
Engagement in the building process:
Experimenting with motion (Adjusting the robot):
Our vibration robot is "Mechanical"—it just turns on and goes crazy. But what makes a robot smart? We will watch demonstrations of AI robots that use sensors to "see" and "think" before they move!
Focus: Identifying a "toy" robot vs a "smart" robot that can talk or see your hand.
Focus: Understanding Sensors. A mechanical robot walks into a wall. An AI robot uses an ultrasonic sensor (like a bat's echo) to stop before hitting the wall!
Focus: Machine Learning and Autonomy. Discussing self-driving cars, Boston Dynamics robots, and how AI code connects to mechanical servos.
Understanding the difference between Mechanical and AI:
