THE PROBLEM

Hypothesis The seeds would cease to germinate after 2.5% salinization

Variables Our group measured the experimental variable, (salt) in increments of .5% per Petri dish, increasing until we reached a maximum measurement of 3.5%.  The salt was mixed in distilled water so that every gram would be congruent with its percentage ex. 5%, 10%, etc.

Materials Petri dishes Ten radish seeds per dish Table salt Paper towels Distilled water Tape Balances Test tubes Labels Graduated cylinder Beaker Permanent marker

Graph

Results At 2.5% the growth was not remarkable and all measurements past 2.5% did not germinate but grew mold over time.  The results therefore were conclusive with our hypothesis:  Water with a salt content greater than 2.5% is not conducive to plant germination or growth.
