Kidney Beans
-we grow some kidneys beans to a plastic cup.
We usualy put water into it in science class. For this growing activity, we devided into 2 groups. 1 group is growing Kidney Beans and the other is green bean.We put our seeds outside, where they can have more energy from the sun. The leaves are now very green.
The difference with the green beans is that this is growing everywhere they wanted. but the kidneys is growing straight instead. The greens beans is puted in the cupboard and the leaves is really yellow. Later i think i should put more water in it.
