What/How/Where?
"The word, Hydroponic, comes from Latin and means working water." (what) and is planting plants in situations where they do not have soil.

"The nutrients that the plants normally derive from the soil are simply dissolved into water... and depending on the type of hydroponic system used, the plant's roots are suspended in, flooded with or misted with the nutrient solution so that the plant can derive the elements it needs for growth." (how)

hydroponics are used "in areas of the world that cannot support crops in the soil" (why)
problem/hypothesis
experimental design
we will have three different environments for the beans to grow in. there will be three different cups. one with soil, one with water, and one with a damp paper towel

we will plant one seed in each cup, and give it 25 ml of water each day, and take a picture of it's growth every three days for two weeks
variables

-Do plants thrive better in a water environment or in a soil environment?
-We believe that the plants will grow best in the soil type environment.
The environment the bean is growing in
-soil
-water
-paper towel

conclusion
Our hypothesis was incorrect, because we thought that the bean in soil was going to grow the most. When in fact the bean growing in the wet paper towel grew the most. The only part in our hypothesis that was true was when we inferred that the bean wasn't going to do well in the water. The reason why bean probably didn't grow in the water was probably because there was no filtration system for the water.


The bean plant in the wet paper
towel grew the most out of all three. The bean in the water didn't grow at all, and the bean in the soil showed no growth outside of the soil. But when the bean was dug out of the soil there were tiny roots, that died out.
