1. Experimental Design SEED GERMINATION OUT OF THE 100 BEAN SEEDS I PLANTED IN MY GARDEN, ONLY 35 GERMINATED INTO HEALTHY PLANTS? HOW CAN I INCREASE THE PERCENT OF BEAN SEEDS THAT GERMINATE?

2. Variables in Seed Germination

3. Temperature of Soil Amount of Light Amount of Water Percent of seeds that germinate Amount of Time Type of Seed

4. THE HYPOTHESIS CHANGE ONLY ONE INDEPENDENT VARIABLE, WHICH SHALL IT BE? o C, H 2 O, Light, Time IF ___(independent variable)_____ IS __(describe change)___ IF THE IS INCREASED THEN __(dependent variable)___ will __(describe change)__ THEN THE WILL INCREASE

5. THE EXPERIMENT Levels of the IV (Drops per hour) Number of Trials IV: Amount of Water DV: Percent of Seed Germination Constants: 1. 2. 3. 4.

6. SIMULATION CLICK TO LAUNCH Gizmo Log On using your Username and Password Type ‘Seed germination’ in Search box then Launch Gizmo SET SEED TYPE TO ‘B’ SET LIGHT TO 50 SET TEMPERATURE TO 25 o C SET WATER TO 25 DROPS/HOUR RUN FOR 5 DAYS CLICK ON GRAPH TAB RECORD RESULTS ON DATA TABLE CHANGE WATER TO 50 (75, 100) REPEAT.
