fossil fuels
fossil fuels
how can I show people that fossil fuel usage affects our planet? :cry:
Re: fossil fuels
Hello,
That is a great idea! One way you could show that fossil fuel usage affects our planet is by looking at data from the past twenty or so years and comparing the usage of fossil fuels to climate change. 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:…

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.

microbiology project
microbiology project
I have to determine what unknown bacteria I have been given after performing a variety of tests, but I am struggling. None of my results perfectly match with research and therefore I am stuck on how to narrow it down.
I am unsure how to interpret a couple of test results, so I have attached some pictures in hopes of receiving some help. Specifically regarding the semisolid motility test -- I cannot tell if this indicates motility or not.
Here are…

Use the Arduino IDE (not Arduino App Lab) for R4
I'm posting this as a general update in case anyone runs into a similar problem. I assisted a student this week who was having a trouble working on an Arduino ultrasonic project. The board wasn't being detected.
They shared this image:

The image shows [b]Arduino App Lab[/b], which wasn't detecting their R4 because Arduino App Lab [b]only works with Uno…
