Magical Beans

Louie’s mom, Hanni, brought us a large cup of mystery beans she had shucked and saved a year or two ago.  We weren’t sure if anything would sprout but we decided to create an experiment about it.  I started by asking the students what different ways we have grown things this year that might work to sprout the seeds.  One suggested, we could put them in dirt like we did with our spinach seeds.  Another proposed water as we had sprouted celery and sweet potatoes and another mentioned garlic that was growing without water or dirt as another option.  The last option was in a plastic bag with a paper towel as we had done with peas.

Students predicted which technique, how long before we would see any sprouts, and how many would come up.

Our experiment required four different options, soil, water, paper towels or a sunny windowsill.  Students counted out ten white and ten dark purple beans and prepared their growing medium.

After everything was set, and predictions were recorded it was time to wait.  With the magic of our huge windows and warm radiator, we did not have to wait long at all.  In five short days, we saw the first beans emerging from the soil.  We observed nothing was happening with our paper towel, water or windowsill plantings.

After ten days, we drew the seedlings and observed that the mystery purple beans were all growing and we drew them.

Two weeks into our experiement, the beans are 20 inches tall and ready to be transplanted into the three sisters garden when we get the go ahead from Marion and Hanni!
