Science Lab ReportTitle: The germanation of plants

Purpose: I want to see how tall a plant grows when there is light or none.

Background information:- pants need water and sunlight to grow- plants are green - plants males their ownb foood during a process called photosynthesis- plants need to grow roots to make food

Hypothesis: I think the plant in the drawer wouldn’t grow because plants need sunlight to make food. I think the plant in the sunlight would grow tall.

Materials: -Two nine ounce cups with one drain hole in the bottom

-Two saucers

-Six zinnia seeds

-Miracle Grow soil

-Water (75ml)

-Beaker

-Ruler

-Data chart

Procedure:Step 1- Fill both cups with soil leaving one inch from the top empty

Step 2- Poke hole in the middle of the soil (1/2 inch)

Step 3- In each cup, put three seeds into the hole and cover with the soil

Step 4- Put 75ml of water in each cup

Step 5- place one cup on a saucer and place it on a windowsill

Step 6- place one cup on a saucer and place it in a drawer

Observations and Data - see attached Chart

Analysis- The plant in the sun grew while the plantin the drawer didn’t.

Conclusion- I learned that plants need sunlight to absorb for there to be photosynthesis to make food for themslefs. I also learned that the hypothesis was true. I learned that water by itslef wouldn’t make theplant in the drawer grow.
