NEW FEATURE: We will be posting STEM NEWS on our Facebook Feed to tease interest in all sorts of interesting new developments in STEM. Watch Facebook! Here is a sample:
Researchers in China have discovered that a kind of spider that mimics ants also feed their young with a protein-rich milk. Experimenters have shown that young spiders depend on this feeding and will die without their mother’s milk. It isn’t unusual that parents feed their young, but it was once believed that only mammals provide milk to their young.

Each month GOSTEM will showcase a different STEM Launch Point and the connections that can be explored in each STEM discipline. These stories are quick summaries of interesting people and circumstances where using STEM was as an integrated way of thinking and necessary to solve the problem. The story we offer in this month is “Oops! I Used the Wrong Resistor!” The unit may be found at: https://sites.google.com/a/eou.edu/stem-stories/greatbach-story)
Sometimes inventors discover something they weren’t intending. That was the case with Wilson Greatbach. He was doing an experiment with an electronic oscillator and used a wrong component. The plans called for a 10,000 ohm resistor and he accidentally used a 1,000,000 ohm resistor. Instead of a tone he had expected, the circuit made a “blip” noise ever second of so. From this accident the idea of a pacemaker was born. Thereafter Wilson’s circuit became the mainstay of all implanted pacemakers for decades. In this series of explorations students experiment with Wilson’s circuit, learn about resistance in electronics, make circuits with liquid conductors, and are invited into the world of electronics technology
In this STEM unit, Students use a cardboard diagram, springs and components to assemble a circuit like Greatbatch’s. They can create the original sounds with a 10,000 ohm resistor and then insert a 1,000,000 ohm resistor to make a pacemaker. Students make their own resistors by using a pencil lead or with by drawing a resistor on a piece of card stock. By combining graphite, rubbing alcohol, and white glue, a conductor can be made and various values of resistance can be painted onto card stock and then tested. Students are invited to make circuit boards using foil that is lightly glued to card stock. The unwanted material can be cut and peeled to make a circuit trace. Components such as resistors, leds, and switches can be added by using a liquid conductor to make working circuits. Students design boards, construct circuits, and test their creations.
