Karla lists the steps of her scientific analysis in the form of a flow chart. Which step should Karla go back to as a result of her conclusions? 1. Sees height of the
same species of sea
grass differs in two
separte locations.
2. Wonders why the sea
grass height in the
two locations differs.
3. Suggests grazing by
marine animals is the
cause of the difference
in height.
6. Concludes that
another factor causes
the difference in height.
5. Observes that the
height of sea grass is
uniform in both tanks.
4. Grows samples of
sea grass in two
separate aquariums-one
with marine organisms
and the other
without them.
