A fun experiment to demonstrate the effect of greenhouse gases on our planet is to simulate it in a jar. Here is a link to instructions for this project:… Read more

Voltage measuring

Ask an Expert Topic Forum: Grades 9-12: Physical Science

Voltage measuring Voltage measuring I’m doing the “dealing with diabetes” project but when I measure the voltage of the conductivity sensor in the distilled and tap water they both come out to 5.07 which I know is above what it is supposed to be. Along with that, the voltage readings shouldn’t both be the same. Is there something wrong with my project? The attached file is what my project looks like so far in case it is an issue with that.
