MaterialsThe materials required for this experiment are as followed: · 10Ziplock Bags· 1000radish seeds· 10coffee filters· tapwater· distilledwater· MortonIodized Salt· teaspoon· 10cups (any size)· 8oz. measuring cup Methodology (procedure):First, select ten separate cups. Then using a marker, label the cups Athrough J. Next, fill them as follows, stirring to dissolve solutions withsalt.Solution A: 8 fl oz. tap waterSolution B: 8 fl oz distilled waterSolution C: 8 fl oz distilled water with ½ teaspoon of table salt.
Solution D: 8 fl oz. distilled water with 1 teaspoon of table salt.Solution E. 8 fl oz. distilled water with 1 ½ teaspoons of table salt. Solution F.
8 fl oz distilled water with 2 teaspoons of table salt. Solution G. 8 fl oz.
distilled water with 2 ½ teaspoons of table salt. Solution H. 8 fl oz. distilled water with 3 teaspoons of table salt. Solution I: 8 fl oz.

distilled water with 3 ½ teaspoons of table salt. Solution J: 8 oz. distilled water with 4 teaspoons of table salt.Secondly, place the 10 plastic bags down in an area where there issunlight at room temperature. Label the top and bottom of each plate with theletter of the solution to be used in each one (A through J). Unzip the bags andput a coffee filter in each one. Using a tablespoon, pour each givenmeasurement of table salt onto the filter in the bag with the same label,making sure it soaks the whole coffee filter. Divide the 1000 seeds into groupsof 100.
Put 100 seeds on the filter of each Bag. Make sure the seeds arescattered evenly over the filter. Zip up the Bags. Place all 10 dishes at roomtemperature out of direct sunlight (seeds don’t need light to germinate andlight can cause fungus to grow). Observe the dishes daily and record number ofseeds that have germinated in each dish and any other changes in the seeds. Safety, ethical orenvironmental issues:You need goggles for the salt water splashing inyour eyes, and gloves so you do not transfer bacteria to the seeds.
