Makerspace: Physics 114 and 115 for Education majors

BUILD THE TALLEST TOWER

How tall can you build a tower using only the planks on your table?

5 MINUTE LIMIT!

BUILD THE WIDEST BRIDGE SPAN

Build two columns Then, create the longest span between the columns WITHOUT a support beneath it

10 MINUTE LIMIT!

One of the easiest circuits to make is a simple circuit. In this tutorial, we will show you how to make a VERY simple circuit using copper tape, an LED and a coin cell battery.

This project can be completed in less than 5 minutes and the template includes two projects per page.

A paper circuit is a low-voltage electronic circuit that is created on paper or cardboard using conductive copper tape, LEDs and a power source such as a coin-cell battery.  Creating paper circuits is a good way to teach the basics of electricity and how circuits function.   In addition to being educational, they can also be a fun makerspace project that helps to bring artwork and paper craft to life.  By adding sensors, buzzers and motors to your circuit, you can also add another dimension of interactivity.  These simple projects are great for all ages and all makerspaces.

Tools You May Need and Not Included:

• Hot glue gun or strong adhesive
• Scissors or wire cutters
• Heat source for the heat shrink tubes (like a hairdryer or lighter)

Basic Instructions to Avoid Short Circuits

1. Understand the Circuit:
   • A short circuit occurs when electricity takes an unintended path with little or no resistance, which can cause overheating and damage components.
2. Check Connections:
   • Ensure that all connections are secure and correctly placed. Double-check that the positive (red) and negative (black) wires are connected to the correct terminals.
3. Use Insulation:
   • Use heat shrink tubes or electrical tape to cover any exposed wires or connections. This prevents accidental contact between wires that could cause a short circuit.
4. Avoid Loose Wires:
   • Make sure all wires are neatly arranged and secured. Loose wires can touch other components and create a short circuit.
5. Test the Circuit Before Powering Up:
   • Before inserting the batteries, visually inspect the circuit to ensure there are no exposed wires touching each other.
   • Use a multimeter to check for continuity and ensure there are no unintended connections*
6. Proper Use of Switches:
   • Ensure that the rocker switch is correctly wired into the circuit. The switch should be in the “off” position when connecting the batteries to prevent any sudden surges. The "I" represents power on, and the "O" represents power off.
7. Battery Polarity:
   • Make sure the batteries are inserted with the correct polarity. Reversing the polarity can damage the components and cause a short circuit.

Visual Guide:

• Red Wire: Connects to the positive terminal of the battery holder and one terminal of the switch.
• Black Wire: Connects to the negative terminal of the battery holder and one terminal of the motor.
• Additional Red Wire: Connects the other terminal of the switch to the remaining terminal of the motor.
