SimPandemic SimPandemic Hi, I just had a quick question about your SimPandemic tool. I know that isn't Life, Earth, or Social Sciences, but I didn't know where else to go. In the SimPandemic stimulator, does it automatically assume that getting infected and recovering means that you are immune? Thanks. Read more

Aquarium ph and alkalinity Aquarium ph and alkalinity I just had my aquarium water tested. I have a pH of 8.4 but alkalinity at 0. Is this possible? Please explain. Re: Aquarium ph and alkalinity Hey hotpockets626, I’m no expert with pH, but the pH scale includes alkalinity and acidity. This link might help. https://courses.lumenlearning.com/wmopen-nmbiology1/chapter/the-ph-scale/ I don’t think that it’s possible to have an alkalinity of zero, because that would be acidic. You… Read more

Why can't we harness thermal energy? Why can't we harness thermal energy? I was watching the show Darling in the Franxx and all the talk about "Magma Energy" made me question why we're not currently harnessing thermal energy on a large scale? (That I know of) I've thought about it and why couldn't we drill a hole deep enough to where the temperatures are 200+ degrees and because heat rises, make a wind tunnel and install a type of wind turbine thus producing energy?

Vermicompost (Worm Poop) Vermicompost (Worm Poop) Hello whoever is reading this, I am a middle school student performing an experiment on worms, to see which conditions worms make the best quality compost. I typically spend 3 hours a day feeding my worms and recording observations, such as pH, % castings, and worms found in the sample taken out. I use pH test strips to measure the pH ( meant for soil), my eye to estimate castings %, and my ability to count to record how many worms there are.… Read more

Question about X-inactivation in calico cats project Question about X-inactivation in calico cats project Hello! I'm a 12th grader that's working on the x-inactivation in calico cats project. I collected all my data, but I'm not sure how to analyze my data. I originally thought that using chi-squared would work, but I don't have expected values. Would the expected values be all equal since the x-inactivation should be evenly spread? Or does the usage of chi-squared not work? Here is the… Read more
