Transcript of Seed Germination
amount of radiation Confounding variables: ziplocks bags, water,
radish seeds, microwave, sunlight, napkins Control Ziplock bags with seeds that were
not microwaved. Organize Data Data Analysis Radiation Radish seeds Ziplock bags Permanent marker Water Napkins Window with
available sunlight Parts of a Seed If radiation affects the germination
of radish seeds, then the more
radiation the seeds receive, the
faster the radish seeds will grow endosperm: nourishment for the baby plant,
in the form of starch, but can contain oils and
protein. seed coat: surround the ovule embryo: immature plants consisting of the
tissues for the leaves, stem, root, and one
or more cotyledon. Plants need sunlight to grow, it may come
in the form of ultraviolet radiation, which is
also produced by electromagnetic radiation. In this experiment, I will be using a microwave
to produce electromagnetic radiation. Conclusions 1. Label each baggie: (5 sec, 10 sec, etc.) 2. Place moistened napkin in each ziplock bag. 3. Make control; put 10 radish seeds lined on moistened napkin. 4. Microwave radish seeds in groups of 10 according to prearranged times. 5. After microwaving, place seeds in according bags. 6. Zip all the bags up and tape them to a window with available sunlight. 7. Let the radish seeds germinate for 3 days. 8. Record the number of sprouted and unsprouted seeds in each ziplock bag
each day for a period of 3 days. From that data I collected, I was unable to
confirm my hypothesis from the radiation levels
I selected. There weren't any indications that the seeds that
were exposed to radiation had more sprouts that than with
less. If I increased the dose of radiation, and made less
errors in my experiment, my results would be more
accurate. Methods Fin ;3 Tape
