Science and technology
Human-transcribed braille
Summary
All around the world – in the sea, in the soil, in the air, and in your body! – there are living things so tiny that millions could fit on the period at the end of this sentence. And they’re… busy doing all sorts of things, from giving you a cold to making yogurt to eroding mountains and helping make the air we breathe. Grades K-3. 2014.
