STEMU Day 2 Part 2 Seeable E-textiles

Our second project was to sew a bracelet using e-textile thread and LED lights.  I quickly learned that my sewing was in need of drastic improvement before i do anything serious.  You must weave then thread through the entire pattern route or the thread wires risk touching and shorting out.  It was a fun activity that took us adults quite a while.  This would be a great undertaking for students.  Perhaps its an opportunity to integrate with CTE Classes.

The wires here can touch shorting the circuit.  Must weave thread.

Finished project had on/off switch and would only work if metal button was snapped to close the circuit.

STEMU Day 2 Part 1 Squishy Circuits

Today we used conductive dough and a non conductive dough to create circuits.  I saw snowmen and wreaths and other fun creations.  The dough acted as a resistor to help control the amount of volts and power through the led bulbs.  We saw Ohms Law in action as we dropped 6 volts to a useable 2.2. 

Our tools for the day.

STEM U Day 1

Today we created paper circuits using two small batteries, copper tape, led lights, and paper backgrounds.

Part 1 was to create a simple circuit to light up a single bulb in our name tag.  I loved how something simple likens name tag could allow us to study circuits.  A fun and engaging activity.

Parts 2 was creating both a parallel and series circuit.  I tried to create both in the same circuit and tried to just adjust the bridge to bypass the parts of the circuit I didn’t need.  Turns out it didn’t work very well.

I saw a peer work a snowman into her parallel circuits.  Just showed me that I’m only limited by my imagination.
