Design and Create a Lightbulb Circuit on Tinkercad
Hosted by: UT Austin Texas Engineering World Health
Visit our Booth: Sunday, March 7, 2021, 12 p.m. - 4 p.m.
Recommended Grades: 4th, 5th, 6th, 7th, 8th Grades
Challenge: Design and Create a Lightbulb Circuit on Tinkercad. Challenge 1: Design a circuit to power a lightbulb (LED) with a battery. Challenge 2: Add in a switch to your design to control when the light turns on or off. Challenge 3: Experiment - what happens when you add in a 2nd LED or multiple LEDs or a resister.
- Select "Circuits" from the menu.
- Click the green "Create new Circuit" button to open up a new circuit project
- Grab the LED from the components menu on the right and place in the open workspace - you can change the color of your LED by clicking on it after placed in the workspace and selecting a different color in the "Color" dropdown menu
- Grab the Coin Cell 3V Battery from the components menu on the right and place in the open workspace
- Hover over the end of the wires on the LED and find the "cathode" wire and the "anode" wire.
- Hover over the red and black wires/connectors on the battery and see which is positive and which is negative.
- Click on the "cathode" wire on the LED and connect the wire to the negative connection on the battery.
- Click on the "anode" wire on the LED and connect the wire to the positive connection on the battery.
- You should now have a complete circuit.
- Click "Start Simulation" to light up the LED.
- You'd just completed Challenge 1!!
For Challenge 2, disconnect one of your wires in your completed circuit. Select either the pushbutton or the slideswitch. Connect the LED to the switch and the switch to the battery. Test it out by starting the simulation and activating your switch. Trade out the switch you selected with the other one and test it.
For Challenge 3, get creative by adding in another LED or a resister and connecting it with wires. Start the simulation and see what happens. How crazy a circuit can you make and still light up the LED or LEDs?

How does this activity connect to STEM and today's Girl Day theme of 1) Creating in Code: Computing, Cybersecurity, Robotics & 2) Imagining Beyond: Sky and Space?
Circuits can be found in almost any real-world engineering project. Circuits are a critical part of all robotic applications, even those used by NASA in space! They are what allow us to use devices like laptops and phones.

If you want to try making Squishy Circuits check out this PBS website for all the materials and instructions!
- Conductive Dough - PlayDoh works well
- Insulating Dough - Clay works well
- Battery Pack and Batteries - 9V and 9V connector with wires or 2 AA Batteries and double AA Battery pack with wires
- Light Emitting Diodes (LEDs)
Instructions for making your own dough can also be found on the PBS website.

Texas Engineering World Health works on medical projects for the developing world. Each year we work on a different project and submit it to the Engineering World Health Competition. We work on researching the prevalent problems that need solutions and we look into making the idea financially feasible for hospitals in the developing world. Lastly, we create a prototype that encompasses engineering skills from all different engineering fields.
