• One person get high CO2
• One person get low Co2
• Compare with two groups and then record results

Clean Up
1. Return all elodea to the aquarium
2. Pour fluid in sink
3. Rinse vial
4. Put vial upside down in bins in back- separate caps in separate bin

Conclusion
• Claim: In the light, plants cause the CO2 level to (increase/decrease)
• Evidence: (give data from BOTH vials)
• Reasoning: (explain why this may have happened using your own understanding)

“WHAT IS PHOTOSYNTHESIS?
![Page 9: December 6, 2011 No homework. Open to “How do Plants Change the Air?” Glue in results table.](https://reader031.fdocuments.us/reader031/viewer/2022032106/56649e105503460f94afb3a9/html5/thumbnails/9.jpg)
• 1) Is sunlight matter or energy? How do plants use sunlight in photosynthesis?
• 2) Plants are made mostly of carbohydrates. What atoms are carbohydrates made of?
SUNLIGHT IS ENERGY AND PLANTS USE IT TO MAKE FOOD (STARCH) IN THEIR LEAVES
CARBS ARE MADE OF C, H, AND O ATOMS
![Page 10: December 6, 2011 No homework. Open to “How do Plants Change the Air?” Glue in results table.](https://reader031.fdocuments.us/reader031/viewer/2022032106/56649e105503460f94afb3a9/html5/thumbnails/10.jpg)
3) In order for plants to make their own food, they need three ingredients—what are they?
PLANTS NEED SUNLIGHT, CARBON DIOXIDE, AND WATER
![Page 11: December 6, 2011 No homework. Open to “How do Plants Change the Air?” Glue in results table.](https://reader031.fdocuments.us/reader031/viewer/2022032106/56649e105503460f94afb3a9/html5/thumbnails/11.jpg)
• 4) How does CO2 get into a plant? How does water get into a plant?
• 5) What part of the plant performs photosynthesis?
CO2 GETS INTO A PLANT THROUGH OPENINGS IN THE LEAF AND WATER GETS IN THROUGH THE ROOTS
THE cells of the LEAVES ARE WHERE PHOTOSYNTHESIS TAKES PLACE

6) Other than making glucose, what else is produced by photosynthesis?
O2 IS ALSO PRODUCED BY PHOTOSYNTHESIS—IT IS LEFT OVER
![Page 13: December 6, 2011 No homework. Open to “How do Plants Change the Air?” Glue in results table.](https://reader031.fdocuments.us/reader031/viewer/2022032106/56649e105503460f94afb3a9/html5/thumbnails/13.jpg)
• 7) What is the formula for photosynthesis?
• 8) After sugar (glucose) is made in the leaves, what happens to it/where does it go?
6CO2 + 6H2O LIGHT GLUCOSE + 6O2
THE GLUCOSE TRAVELS TO THE REST OF PLANT SO IT CAN BE USED BY THE CELLS
![Page 14: December 6, 2011 No homework. Open to “How do Plants Change the Air?” Glue in results table.](https://reader031.fdocuments.us/reader031/viewer/2022032106/56649e105503460f94afb3a9/html5/thumbnails/14.jpg)
MATTER: 6 water (H2O) + 6 carbon dioxide (CO2) → sugar (C6H12O6) + 6 oxygen (O2)
ENERGY: light energy → chemical energy

What we already know:
• Potatoes contain starch
• Potatoes grow underground.
• Only the above ground parts have green leaves.
• Soil and water aren’t food.
• Question: where does the starch in the potato come from?

To Do Today
1. Get a packet (1 per table) and a chart (1 per person) from the front counter
2. Summarize what is happening in the plant from time 0-5 in your chart.
3. We can do the first one together.
