Hypothesis: If the Mung Beans are watered with a higher salt solution, then less Mung Beans will sprout.
Introduction This experiment was done to test the effect of salt solution on mung bean growth. Generally when you grow mung beans you soak them in water for eight to twelve hours and then put them in a separate container to sprout. Since this experiment was not monitored every hour, and had limited resources, we could not soak the mung beans for that period of time. There are multiple ways to grow mung beans but since the experiment was to test the effect of different salt solutions, one particular way was chosen. Methods 1. Gather two paper towels and two petri dishes, no safety goggles or gloves will be required for this experiment. 2. Place a petri dish on a paper towel and trace the bottom of it so a circle is drawn. Do this twice on each paper towel so there are four separate circles drawn. 3. Separate the top and bottom of each petri dish so they can each be used separately, creating four dishes. 4. Label the petri dishes: Distilled, .25 solution, .50 solution, and .75 solution 5. Cut out the circles that were traced on the paper towel sheets. 6. Place one paper towel circle in the bottom of each dish. 7. Now take a graduated cylinder and place 20 mL of distilled water in it. 8. Pour the 20 mL of water on top of one of the paper towels in the dish so it can soak up the water. 9. Repeat step seven with a .25, .50, and .75 salt solution. Be sure to put each one in a separate petri dish with a paper towel circle in it. 10. Place 20 mung beans in each petri dish; be sure to check that the mung beans are spaced apart from each other. 11. Place the petri dishes on a counter and leave them there for five days. 12. Take measurements each day and record results. Results Table 1: Amount of
