Transcript Photosynthesis Presentation

Plants Store Carbon
from the Atmosphere
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.

Materials
Cut out and labeled prior to the lab
For each pair and placed in a ziplock bag
• 6 carbon atoms (black circles)
• 12 hydrogen atoms (small white circles)
• 18 oxygen atoms (larger red circles)
