Bean Sample

Bean sample 10/11/16
Our hypothesis was that the bean covered with dirt would die because it had no oxygen.

Bean 1  1cm long 2mm wide
Bean 2  2cm 3mm long 1cm wide

Bean 1  10cm tall
Bean 2 DEAD

Bean 2 had weeds growing.

I threw out bean 2 because it had died.

Based on our results, we can conclude that our hypothesis was incorrect. We now know that beans don't need oxygen to survive and that seeds grow better underground because the soil provides all the nutrients that are needed.
