  2. Beyond the Basics (water AND either light, soil, or air)
  3. Unusual Liquids (dish soap, vinegar, baby oil, salt water, and sugar water)
  4. Temperature (room temperature, freezer, refrigerator, heating pad)
  5. Seed Parts (seed coat, seed leaves, and embryonic plant)
  6. Types of Seeds (navy, kidney, corn, pumpkin, and sunflower)

 

 

1. The Basics
