Take 10 minutes to notice the nature around you. Life science is happening everywhere… and you are a part of it. Record your observations, make sure you describe both the abiotic factors and biotic factors during your time outside. You may use words or pictures for your descriptions. Record at least 2 quantitative observations for each factor. And remember…. Enjoy this time!

Don’t fill my head with the logic and science behind the phenomenon.

Let me bask in it’s glow.

Let me shake my head in wonder.

Let me sit quietly and take it all in with my own senses.

Let me accept it as a miracle of life.

Tell me about the myths.

Share a bit of folklore.

Talk with me about mystery

The mystery of it's very existance.

And you will fuel my belief in God

A bright blue sky as far as the eye can see

A perfectly spun web covered in morning drops

A 12 foot high sunflower which started from a seed I held in my hand

Flickering stars on a summer night blending into one another
