Because no matter what I search for, I can't find the old one. If anyone can find it and merge this with it, please do!
DD7 brought home a science worksheet from 2nd grade. Some of the questions have me stumped as to what they really want.
"Tell whether water is a liquid or a solid in each picture." And the pictures are a house with snow on it, a fish bowl, and a pan of water on the stove with steam coming out of it. Now, I would expect the steam one to be gas, as did DD, but that's not a choice -- it does have water still in the pan, so we went with liquid.
"Tell what happens when heat is taken away from water." Umm, it gets cold? How much heat, exactly? Might or might not be enough to make it freeze. "Tell what happens when heat is added to liquid water." Again, how much heat? It gets hot, it boils, it evaporates...depends.
"What kind of change is it when matter can be changed back to the way it was?" This would be fine, but it's not until the next page when they explain reversible and irreversible. This is a page about liquid and solid.
And the next page, reversible and irreversible, is a real conundrum.
"Decide if the change is reversible or irreversible." First one is easy, an egg and a fried (or at least dumped out) egg. Then comes a bowl of ice cream, melting. Hmm. Well, ice cream can be re-frozen, but it doesn't come out the same. Hard to say what they're going for. Then comes a picture of what DD says is popcorn but I thought was drops of water and clouds. One is reversible, the other isn't. Then a picture of a bunch of screws and washers. They can be melted, so it must be reversible. And the last one is what appears to be a rusty nail. Rust can be removed, but it's not exactly reversible. She didn't even know what "that stuff" was on the nail.
The last page has three words, reversible, irreversible, and mixture, and three pictures to label with them. A pond that may be frozen because it has trees with snow around it, a pizza with a slice missing, and a bowl of fruit. WTH? Is a pizza irreversible, because you can't unmake it, or a mixture? Is a bowl of fruit a mixture, or irreversible because you can't put it back on the trees? Who knows?
