The baking soda provides the carbon dioxide that the leaf needs for photosynthesis. The leaf disks are then sunk in the baking soda solution and exposed to light. As the plant leaf photosynthesizes, oxygen is produced that accumulates as oxygen gas bubbles on the outside of the leaf disk.
Every science fair project can be broken into eight primary sections. When you present your project to a class or the judges of the science fair, you will need to ensure that each of the main eight elements is adequately represented on both your presentation board and your lab reports.
Learn all about leaves with HST! Find out their purpose, why they change color, and why they fall from trees. Science projects and print worksheet included.
Leaf cells are full of organelles called chloroplasts, which contain chlorophyll, a pigment that absorbs light. (Chlorophyll absorbs all the red and blue wavelengths of light, but it reflects green wavelengths, making the leaf look green.) Leaves cannot perform photosynthesis without chlorophyll.
Revise the structure of a leaf and how it has several adaptations for photosynthesis with this BBC Bitesize Biology KS3 guide.
What is Photosynthesis? Effects of Ultraviolet Light on Plant Growth and Development. Elementary School - Grades 4-6. P =Project E =Experiment. Use Floating Leaf Disks to Study Photosynthesis [E] Test if the color or wavelength of light will affect the chlorophyll content of a leaf. [E] How do plants make food (photosynthesis basics)?
