The bean seeds are going to be put into different situations. We will have the small, medium, and large holes for boxes with mazes inside them. The mazes are all identical and used the same materials. We will see if the amounts of light for the different seeds will make them sprout faster or bigger. Also we will make sure we pay attention to coloration. Our main goal is to see if the seeds with the most light will grow the most, and the seeds with the least amount of light grow the least. This is also our expectation or hypothesis that the amount of light given to the plant will cause the plants to grow at different rates.
 * __Bean Sprouting__**
 * __Introduction__**

The experiment Bean Sprouting can relate to real life in a few different ways. For one thing the Bean Sprouting experiment can relate to how flowers and plants in our garden are grown. When getting a flower usually there is a tag that comes with it saying the best conditions for the plant to be grown in. Also we can learn about dehydration in humans from the flowers. We can tell how much light can absorb the water and how quickly which may help out scientists. Plants are very important to the environment and we need to know how they grow in different circumstances.


 * __Independent Variable(s):__** The independent variable is the light. For each sets of seeds the light level will be different.


 * __Dependent Variable(s):__** The dependent variables are the seeds. The seeds both have different amount of light given to them.


 * __The Materials needed are…__**
 * Soil (same amount for each plant)
 * Bean seeds (in our case we need 4 for each container so 12 seeds)
 * 3 containers
 * Cardboard boxes to create mazes
 * Tape
 * Scissors
 * Ruler
 * Lamps


 * //__Caution__//**
 * During this experiment be careful when cutting the cardboard
 * Also wash your hands when handling the soil
 * Lamps may be extremely hot when you touch!


 * Wowee this is fun! ||

During this experiment we have a few different expectations. We mainly expect that the plants will grow more or larger dependant on the size of the hole in their box where the light is going through. This means that we expect the seeds that are exposed to the most light will grow the largest (Liza’s seeds) and that the seeds with the least amount of exposure to the light will grow the least (My seeds). From those measurements we expect that the plants exposed to the middle amount of light (Destinies seeds) will grow somewhere in between those measurements. The next expectation is that the plants will grow to be a decent size. We believe that under our different variables of light and water that the seeds will be able to grow into green plants. We are already starting to see the green coming out in the seeds but now they need more time to grow. Also we are expecting roots to start growing outwards within the plants. We have a few different expectations for our experiment but our main expectation depends on the amount of light given to the plants.
 * //__Expectations__//**

The **Basic** overview of our expectations….. 1. The box with the biggest hole will have the most well grown plants. 2. The box with the smallest hole will have the least well grown plants. 3. We expect the plants to grow differently. 4. We expect the plants to become green from working chloroplasts. 5. We expect the plants to grow roots.

Our experiment is located on page 640 in the Biology book. Although we have changed the experiment a little the basic experiment is explained on that page.

This is the graph we made!


 * __Words to know__**

1. Buds- [Old English]Contain undeveloped tissue that can produce new stems and leaves. In the spring some flowers buds bloom.

2. Embryo- [ en coming from in which comes from the word bruein to mean full of bursting] Is an organism in its early stage of development. The embryo contains the beginning of a plant.

3. Epidermal Cells- [?]The outer covering of a plant of dermal tissue, which typically consists of a single layer of epidermal cells. Many plants have epidermal cells to protect the easily harmed tissue within the plant.

4. Fibrous Roots-[?] Roots that branch to such an extent that no single root grows larger than the rest. Fibrous roots grow out like little strings unlike how carrots grow.

5. Leaves- [Old English] Are photosynthetic organs that contain one or more bundles of vascular tissue. Leaves grow on trees, flowers and many different plants.

6. Lignin- [ from latin meaning lignum which means wood and within] A substance that makes cell walls rigid enables vascular plants to grow upright and reach great heights. Lignin is needed in plants so that the plants don’t fall over when growing!

7. Mesophyll- [ from New Latin and Greek mesophyllum having the part mes and phyllon meaning leaf] A specialized ground tissue found in the bulk of most leaves. Many leaves contain Mesophyll, a type of healthy tissue.

8. Nodes- [?] Stems contain nodes and these are where leaves are attached. Stems have small nodes that usually become a bigger part of the plant.

9. Phloem- [ from Greek phloios meaning bark and phlein abound, and phlyzein to boil over] Transport solutions of nutrients and carbohydrates produced by Photosynthesis. Phloem is an important part of a plant because it carries nutrients to help the plant grow.

10. Plants- [ from Latin word planta meaning sprout or seedling] Plants are multicellular eukaryotes that have cell walls made of cellulose. They develop from multicellular embryos and carry out photosynthesis using the green pigments chlorophyll a and b. Plants grow all over the world creating a healthy environment and providing food.

11. Roots-[ from Middle English word rot] Are underground organs that absorb water and minerals. Plants have roots that grow and spread out underground.

12. Root Hairs- [?]Tiny cellular projections that cover the roots epidermal subsystem. Root hairs help the roots grow outwards, helping the plant collect more nutrients.

13. Seed- [ from the old english word sawan meaning to sow or old germany meaning sat or seed] An embryo of a plant that is encased in a protective covering and surrounded by a food supply. Seeds are the begging to many plants and are the base of a plant.

14. Seed Coat-[?] Surrounds and protects the embryo and keeps the contents of the seed from drying out. The seed coat provides protection to the new seed that will start to grow.

15. Sieve Tube Elements- [?] The main phloem tubes. The sieve tube elements provide a passageway within the plant so particles can get through.

16. Stems- [ from old english meaning stefn to see]Supporting structures that connect roots and leaves, carrying water and nutrients between them. The stem of a plant is the main structure that holds up the whole plant.

17. Tracheids- [?]The first vascular plants new type of cell specialized to conduct water. Tracheids take care of water distribution throughout a plant.

18. Veins- [ from the middle english word veine]Vascular tissue is gathered in veins, and is made of xylem and phloem. Veins spread through the plants and create passageways.

19. Vessel Element-[?] A type of xylem found in Angiosperms. The vessel element is yet another passageway for water and proteins to get around in the plant.

20. Xylem-[ from the greek word xulon meaning wood]A transport subsystem that carries water upward from the roots to every part of the plant. Xylem is needed in many plants because it is one of the main suppliers of water that is necessary for a plant to grow.
