Research Questions:

What factors affect seed germination?

Plants grow through a process called photosynthesis, when the chlorophyll located in the chloroplast of the plant cells grabs sunlight and starts the reactions that are needed to make the plant grow. Water is also needed in the growth equation, because like humans and animals, plants need moisture to quench their thirst. But does the angle of the seed in the soil affect the plant's ability to absord sun and water? Let's find out.

Materials:

  • Twelve bean seeds (same age)
  • Four plant pots
  • Soil
  • Water
  • Sunlight

Experimental Procedure

  1. Put some soil in each plant pot up to the ledge.
  2. Poke three spaced-out holes into each of the four pots.
  3. In the first pot, insert three seeds (one in each hole) vertically. Close the holes up and give it a pat. Label the pot “Vertical-Up.”
  4. In the second pot, insert three seeds in there vertically, but inversed. Close the holes up and give it a pat. Label the pot “Vertical-Down.”
  5. In the third pot, insert three seeds in there horizontally, with the concave part up. Cover the holes with soil and give it a pat. Label this pot “Horizontal-Up.”
  6. In the fourth pot, insert four seeds in horizontally, with the convex part up. Cover the holes with soil and give it a pat. Label this pot “Horizontal-Down.”
  7. Take these pots to a spot with adequate sunlight and give each a little water (measure the same amount).
  8. Observe which seeds germinate first.
