Introduction

• 1. Research Facts
• a. A seed is a ripened plant ovule containing
  an embryo.
• b. Germination is to grow or develop.
• c. The conditions that cause seed to germinate
  is that the soil temperature needs to be in the
  appropriate range and when water and oxygen are
  available.
• 2. Problem or Question to solve
• a. Problem Farmer Pham needs to know the best
  way to germinate beans.
• b. Testable Question What are the optimal
  conditions for geminating healthy pinto beans?
• 3. Testable Hypothesis We think chemical
  fertilizer will work the better to germinate
  healthy pinto beans because people buy so much of
  it and they wouldnt buy it if it didnt work. It
  will work better than eggshells or fruits and
  vegetable skins.

Materials

• 3 plastic bags
• 3 plastic cups
• 30 pinto beans (10 in each cup)
• 2-3 eggshells
• 30-40 ml. Of chopped fruits and vegetable skins
• 30-40 ml. Of chemical fertilizer
• 200 ml. Of soil
• 80-100 ml. of water

4
Procedures

• First we label the cups and bags
• Chop the fruits and vegetable skins and crush the
  eggshells
• Fill the cups with 200ml. Of soil
• Select 10 bean seeds and randomly spread them on
  the soil
• Cover the beans with a thin layer of fertilizer
  in 1 cup, the vegetables skins in another cup and
  the crushed eggshells in the last
• Then cover the fertilizers with soil
• Put 30-40 ml. of water on top of the soil
• Record your results and water the plants with
  4ml. Of water each day

Data Analysis

• The fruits and veggie skins started out ahead in
  germinating but then the Fruits Veggie skins
  started locking in the moisture and the seeds got
  all moldy and then the Eggshells got ahead.
• The beans sprouted but none of them grew into
  plants.
• All of the beans in the eggshells germinated and
  fruits vegetable skins only germinated 7 beans.
  The egg shells germinated 3 more beans than the
  fruits veggie skins.
• The beans in the Fruits veggie skins got old
  and moldy.

Conclusion

• Yes, our hypothesis was incorrect.
• The fact that the veggie and fruit skins trapped
  in moisture and molded the beans might have
  affected the experiment.
• If we did our experiment again we would have
  chopped the fruits and veggie skins finer so they
  could not trap in moisture. Our new hypothesis
  would be that the egg shells would work better
  because of the calcium that they would provide
  the seeds.
• Farmer Pham should use egg shells to fertilize
  his pinto beans so they grow up healthy and
  strong.
