How to Grow a Lima Bean
By Jennifer Brooks
What is in soil?
• Pieces of rocks that
have been broken
down
• Water
• Minerals and nutrients
• Air
• Sticks, leaves, and
other living materials
Types of Soil
Loam
Clay
Clay can be red, gray, or
other colors. It feels cool
and smooth in your hands.
It holds a lot of water,
hardly any of it drains out.
Loam is dark brown or black. It feels
mushy in your hands, sometimes
a little grainy and sometimes
smooth. It holds water well, but it
lets some water drain out.
Sand
Sand is usually light brown
and feels grainy in your
hand, like salt. It does
not hold water very well,
most of it drains out.

Hypothesis
We think the
bean plant will
grow best in red
clay because it
holds the most
water.

Results
We found out that lima
beans grow best in
sand. The plant we
grew in sand had lots
of leaves and it grew
the tallest.
Can anything stand alone? NO!
We found out that nothing can truly stand
alone because everything has its own
needs. Plants need soil, air, water, and
sunshine to live. Soil has to have rocks,
air, and other stuff to be useful to plants.
We need plants for oxygen, food, and
shade. We need soil to grow plants to
keep the ground from being muddy so we
can play outside.
