Water comes up the stem and into the leaves
Your desktop is going to be the inside of the leaf.
On your desk make as many water molecules as
you can

How many oxygen gas molecules were you able to put
together?How does the oxygen get
into the atmosphere?

Using what you have just learned, explain how plants
“make” oxygen.
Include each molecule that is part of the chemical reaction of photosynthesis and how it got into the leaf.

Creation of something new and more complex from simple things
Materials
• 6 carbon atoms (black circles) • 12 hydrogen atoms (small white
circles)• 18 oxygen atoms (larger red circles)
Cut out and labeled prior to the lab
For each pair and placed in a ziplock bag
