–Soren

I’m writing this poem
From inside of my egg.
And it’s rather wet in here.
I don’t really like being
In here and I want to
Break out!
So in a few weeks
I will wriggle and wriggle myself out
Of this old egg
To the sunny stream.

Modeling Photosynthesis

Thank you Barbara for leading this chemistry lesson!

Why, and how, do plants release oxygen? Using gum-ball models of molecules, we discovered that when plants break down H20 and carbon dioxide to make sugar, oxygen atoms are left over!

Building the ingredients plants need: water and carbon dioxide molecules

Each group first built the reactants needed for photosynthesis: 3 water molecules and 3 carbon dioxide molecules

After taking the water and carbon dioxide molecules apart, students used their atoms to build a sugar molecule

Sugar molecules are long!

Ta da! 1 sugar molecule to give the plant energy; lots of (yellow) oxygen molecules left over for us to breathe!
