The materials required for this experiment are as followed:
cups (any size)
oz. measuring cup
First, select ten separate cups. Then using a marker, label the cups A
through J. Next, fill them as follows, stirring to dissolve solutions with
Solution A: 8 fl oz. tap water
Solution B: 8 fl oz distilled water
Solution 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 is
sunlight at room temperature. Label the top and bottom of each plate with the
letter of the solution to be used in each one (A through J). Unzip the bags and
put a coffee filter in each one. Using a tablespoon, pour each given
measurement 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 groups
of 100. Put 100 seeds on the filter of each Bag. Make sure the seeds are
scattered evenly over the filter. Zip up the Bags. Place all 10 dishes at room
temperature out of direct sunlight (seeds don’t need light to germinate and
light can cause fungus to grow). Observe the dishes daily and record number of
seeds that have germinated in each dish and any other changes in the seeds.
Safety, ethical or
You need goggles for the salt water splashing in
your eyes, and gloves so you do not transfer bacteria to the seeds.
