"Newton - Ask a Scientist" online resource

Dear Colleagues,

Sometimes a question pops in my head from out of no-where...today it was about "sleep"..."What is sleep?" Biologically, Evolutionally, etc.

I thought about different common animals and how they sleep, and indeed-- Do they sleep? I worked my way down the "animal kingdom" and got to fish -- Do fish sleep?

I typed the exact words in Google...and voila!
"Newton - Ask a Scientist" had a good concise answer. :-)

I will let you discover that for your own pleasure, and realized that this would be a fun resource for students as well...

Now I will probably start a new habit of "question of the day" or "week"...

Curious minds want to know...
