So in the last week of school, there seems to be one big missing piece from understanding where everything "disappears" to and how each organisms eats. And that's plants. What do they eat? How do they eat?
We have some background knowledge on this. And we think that plants need water, sunlight, nutrients, air and soil. We had a bit of a discussion on whether nutrients and soil were the same thing (and we can't really understand what they are or how they're possibly different). We also talked at length about how whatever plants eat must have weight, too, since the only way we've been able to prove so far that something eats something else is because it gains weight.
So in the less than 7 days we have left in the school year, we're going to try and figure out some stuff. We set up some pretty rudimentary bean plant experiments. We're going to see how the bean plants grow (or even if they do at all). And we're going to see how the things that we put with the beans create more weight for the beans.
We are recognizing that there may be a whole bunch of errors involved in our experiments, like air leaking into the bags, mold growing on the beans because they were pre-soaked, way too hot temperatures (it's like 90 here in Chicago, and we only have one window unit in our classroom that's shut off at the end of the school day). But we're trying to see if the beans gain weight from the other stuff that has weight in the bags.
