All About Germination

Today's hands on activity for science was put together with some friends. We chose a bean seed germination experiment. Five jars are involved:

  • Jar 1 - we placed a couple of moist paper towels loosely in the jar with three bean seeds which was placed in the windowsill for warmth.

  • Jar 2 - This jar was prepared the same as jar one but placed in the refrigerator.

  • Jar 3 - This jar was prepared the same as jar one but with dry paper towels.

  • Jar 4 - This jar was prepared the same as jar one but steel wool was placed inside the jar to absorb all the oxygen.

  • Jar 5 - This jar was also prepared the same as jar one but with black construction paper to block out light.

We have a data sheet to record our progress for the next 10 days. Each jar has one source it needs taken away from it - oxygen, light, or water. We will report by in 10 days with the winner.

Zach, Nathan, and Abigail checked their jars today. They were so excited! Don't forget to add a little bit of water to jars 1, 2, and 5 to keep the paper moist.
