Title: Seed Germination and Growth  Purpose: To determine if fish nutrient water affects the germination and growth of a Mung bean  Research Question: Does watering a Mung bean with fish nutrient water affect its germination and growth?  Background Information:  Germination – When a plant emerges from a seed  Factors that affect germination and growth of a plant  Air  Light  Moisture  Temperature  Substrate or Medium  Type of seed

Hypothesis If… (cause) Then… (effect) Because… (rationale)  If…_______________________________________________  Then… ____________________________________________  Because… _________________________________________ Seed Germination and Growth

Materials  Water (10 ml)  Fish Nutrient Water (10 ml)  Pipet  Petri Dishes  8 Paper Towel Squares (8 cm x 8 cm)  4 Seeds of ______  Forceps  Magnifying Lens  Labels  Ruler  Scissors  Beaker  Erlenmeyer Flask

Procedure 1. Petri Dishes should be labeled for you already, with Group # and Period # 2. Cut the paper towel into eight, 8cm x 8cm size pieces 3. Label the paper towel to identify the location of seed #1 & #2 & another set of paper towels with seed #3 & #4 4. Place two paper towel squares in each petri dish with 2 seeds in each (use forceps to carefully place seeds) 5. Pour 20 ml of tap water into a beaker 6. Measure 7ml of tap water (Control) with the pipet, and pour it into the Control petri dish

Procedure continued… 6. Empty tap water in the sink and Pour 20 ml of fish nutrient water into the beaker 7. Measure 7ml of fish nutrient water with the pipet, and pour it into the fish nutrient petri dish 8. Take measurements in millimeters and draw each seed 9. Cover the seeds with two more paper towel squares, and cover with the petri dish lid (make sure that the napkin does not stick out of the petri dish) 10. Rinse the pipet and beaker 11. Place both petri dishes on the class period’s tray 12. Clean up your area and reset your lab station
