Your home has millions of invisible invaders--tiny lifeforms called microbes. Some microbes might make you sick and might spoil foods, while others help process the foods we enjoy eating.
Lisa Trumbauer has written early-learner books for Scholastic's Jump Start series and published numerous other activity books, picture books, and novels for middle-school readers, including the New York Times bestseller A Practical Guide to Dragons.
OK, well, we got a bunch of these ones at the same time ["Tiny Life In A Puddle," "Tiny Life In The Air"] but let's just talk about this one. I thought when it said "tiny life in your home" that it'd be like bugs and mice and stuff, you know, like spiders and flies and stuff you can see but it's little. Except in THIS one, we're talking REAL tiny. Like INVISIBLE tiny! And you know, you can't see these guys, like bacteria, but you can see what they DO. And what they DO is, they make food gross. Like wrinkly rotten apples and moldy bread with spots. But you know what? They also make yogurt. So go figure. So this one was a surprise and I learned something from it. So there's homeschool for you!
This can be used for observations and experiments. Students can go home and record the bacteria's that are living in their home (mold on foods, mildew in bathroom) then once the observations are complete you can do a class graph.
