  1. For those of you who need a scientific graphing calculator for your student, Staples has the TI-84 Plus on sale for $88 with free shipping. I haven't seen that low a price yet.
  2. I wouldn't do that - you don't want preservation materials embedded in the small nooks and scratches in your pan and then re-use it for food. If money is an issue, save the styrofoam meat trays from the market (you'll need a larger one for a fetal pig, a smaller one for a worm) and use that. If the pig is adequately and properly cut, the meat tray will hold.
  3. I agree with this. But I have to emphasize, for a kid who isn't interested in biology, I absolutely love GH - interesting and engaging material that broadly educates in the field of biology. I haven't seen a non-sciency biology curriculum as good as GH anywhere in the homeschool market.
  4. A close relative of mine solved this problem with her mother by hiring a night-time attendant. The relative's mother did not need medical needs attended to at night, she just needed assistance with getting to the bathroom, being re-directed to bed, adn night-time wakings in general, so she didn't need to pay a nurse; she just needed an adult babysitter. So if you can go that route, that would be best, because you have to sleep.
  5. I think the bolded is true; we're going to be playing whack-a-mole for several years (not just 2) until most of us have been infected and develop some immune memory response. I don't believe we will see a safe and effective vaccine ready for the average Joe's arm within a year or 2.
  6. It's always been this, in order to shut up someone so they don't have to deal with the issue Karen brings up.
  7. I just want to update here: *This* worked! I can now do 3 whole situps, LOL!
  8. I think GH is a great choice for a non-science/non-biology kid and I am using the botany curriculum for my son because he detests biology and will never go into any field that remotely needs biology. But if you have a kid who is sciency, or who may specifically need biology as a college student, I would just get a more rigorous program and use the GH resources as a supplement. It's not worth the effort, IMO, to re-tool it to be a rigorous college-prep biology program.
  9. No, it's an adjective to describe a medical condition.
  10. You are exactly right about the bolded, as far as how immune memory works. I teach this stuff at a college level and was hoping to gain some insight into why it was reported as a disaster if someone does not have antibodies after they are recovered from covid. I am unclear why the lack or presence of antibodies is reported breathlessly in the news, since it tells very little about immune memory past 6 months (when antibodies would be expected to have died off or greatly decreased). Immune memory cells would tell much more, as you noted, although they are harder to measure. It seems the media outlets are pushing the idea that there is no immune memory, that is, that the presence of antibodies = presence of immune memory cells, which isn't necessarily so. I'm unclear whether it is misunderstanding of the science on their part, or intentional whipping up of worry and anxiety.
  11. Our goals for dual enrollment were 1) to be able to show capability with college classes, 2) knock out a class faster (a one-semester college class is equivalent to a year high school class), and 3) (hopefully) obtain some credit for college if the course transfers to the 4-year uni.
  12. Algebra 2 continues the pattern of constant review. I would give him the Saxon placement test and also have him test through the tests in the Saxon Algebra 1 book. Use the results you get from these two evaluations to place him properly in Saxon.
  13. This is exactly how immune memory works. What matters is the functioning of the immune memory cells. If that were not the case, no one would be pursuing a vaccine. The expectation is that a healthy immune system will generate memory cells to take action (i.e. antibody production) against the virus when exposed at a later date.
  14. Antibodies are proteins, which degrade after not too long a time. I would expect them not to last a long time, because....proteins are degradable. "...the efficacy of a vaccine hinges on the idea that a dose of weakened or dead virus can prompt your body to generate antibodies that protect you from future infection". A vaccine triggers memory cells to produce antibodies when needed. So even though antibodies might be low at any given time after your body has cleared an illness, if you are exposed to the virus, memory cells would multiply, ramping up their production of antibodies again when presented with an immune threat. I might be being dense, or the media may not be reporting this in a carefully-worded manner, but I would only be alarmed if there were not functioning memory cells or antibodies were not produced in response to the given immune threat. Otherwise, why pursue a vaccine at all? What am I missing here?
  15. Praying for your friend, that he recovers soon.
  16. I was wondering that. But I wasn't sure that would work because men's feet are different than women's (at least that's what the Timberland people told me a while ago, LOL).
  17. I should probably call them and talk to them. I looked through their website and all that was listed was B-medium width, and that's why I didn't call them.
  18. I'm looking for paddock boots.
  19. Hoping someone who rides horses can help me with this. My current English riding boots are Ariat brand and fit well a year ago. However, my foot has a progressive condition where I need wide riding boots, which I haven't been able to find. Can anyone recommend a source for wide English riding boots? I am willing to pay for custom boots.
  20. Unfortunately, some people have a genetic predisposition to hypertension and nothing except meds will lower it.
