Title: Seed Germination and Growth Purpose: To determine if fish nutrient water affects the germination and growth of a _________ seed Research Question: Does watering a _______ seed 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

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

Materials Water (5 ml) Fish Nutrient Water (5ml) 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 Label one petri dish top and bottom set with: Period, Group #, Control Period, Group #, Fish H2O Cut the paper towel into eight, 8cm x 8cm size pieces Place two paper towel squares in each petri dish with 2 seeds in each (use forceps to carefully place seeds) Cover the seeds with two more paper towel squares Pour 10 ml of tap water into a beaker

Procedure continued… 7. Measure 5ml of tap water (Control) with the pipet, and pour it into the Control petri dish 8. Empty tap water in the sink and Pour 10 ml of fish nutrient water into the beaker 9. Measure 5ml of fish nutrient water with the pipet, and pour it into the fish nutrient 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
