🟢 Grade 1 – Glowing Greeting Card

Project Idea: A handmade greeting card that lights up when opened!

🔧 Materials Needed:

• Coin cell battery (3V)

• 5mm LED light (any color)

• Copper tape (or aluminum foil + tape)

• Paper or card sheet

• Tape and scissors

📘 Concepts Learned:

• What is a circuit

• Battery = power source

• LED = light that uses electricity

🛠️ Steps:

1. Fold a card in half.

2. Stick copper tape (or foil) inside the card to create a path.

3. Place LED legs on the copper tape: long leg to (+), short to (–).

4. Tape the coin cell so it touches the foil paths.

5. When the card closes, the circuit completes and the LED glows!

📌 Safe for ages 5+ with adult help.

🟡 Grade 2 – Simple Paper Fan

Project Idea: Make a fan that spins with the push of a button.

🔧 Materials Needed:

• DC motor (3V)

• AA battery holder (2x AA batteries)

• Push-button switch

• Paper (for the fan blade)

• Tape

📘 Concepts Learned:

• Motors convert electricity into motion

• A switch starts/stops the flow of electricity

• Positive and negative terminals

🛠️ Steps:

1. Cut out a paper pinwheel or fan shape.

2. Tape it to the motor shaft.

3. Connect the motor to the battery holder using wires.

4. Add the push-button switch between one wire.

5. Press the button → the fan spins!

📌 Fun for ages 6–7 with supervision.

🟠 Grade 3 – DIY Night Light

Project Idea: A mini lamp that turns on when it’s dark using a light sensor.

🔧 Materials Needed:

• Light-dependent resistor (LDR)

• LED

• 3V coin cell battery

• Resistor (220 ohms)

• Tape or breadboard

📘 Concepts Learned:

• Sensors respond to light

• Resistors control current

• LEDs light up when current flows

🛠️ Steps:

1. Connect the LDR in series with the resistor.

2. Connect the LED after the resistor.

3. Attach the battery to complete the circuit.

4. Cover the LDR with your hand → LED turns on!

5. Remove hand → LED turns off.

📌 Easy circuit to explain day/night sensors.

🔵 Grade 4 – Water Level Detector (Using Aluminum Foil)

Project Idea: Create a simple water level detector that lights up when water touches it.

🔧 Materials Needed:

• 2 strips of aluminum foil

• LED

• Battery (3V)

• Cup with water

• Tape

📘 Concepts Learned:

• Water conducts electricity

• Open vs. closed circuit

• Practical use of sensors

🛠️ Steps:

1. Tape 2 foil strips inside a cup, leaving a small gap between them.

2. Connect each strip to the battery and LED using wires.

3. Add water slowly.

4. When water touches both strips, the circuit completes → LED lights up!

📌 Great way to demonstrate circuits in nature.

🟣 Grade 5 – Touch Sensor Lamp

Project Idea: Make a lamp that lights up when you touch two foil pads.

🔧 Materials Needed:

• LED

• Coin cell battery

• Two pieces of aluminum foil

• Wires and tape

📘 Concepts Learned:

• Human body conducts electricity

• Touch can act as a switch

• Simple closed circuit

🛠️ Steps:

1. Stick the two pieces of foil on a table, spaced apart.

2. Connect one foil to the (+) side of battery, the other to LED's (+) leg.

3. Connect LED’s (–) leg to battery’s (–) terminal.

4. Touch both foil pads with fingers → LED glows!

💡Tips for Parents & Teachers

• 🧰 Use low-voltage (3V) batteries for safety

• 🧠 Discuss real-life applications (e.g., night lights, fans, touchscreens)

• 🎨 Encourage decorating and naming their inventions

• 📸 Let kids present their project or record videos for science fairs
