Sunflowers and Acid Rain Talent 21 Project By Jermaine Philo Date 5/10/12 Period 8th
Introduction • The purpose of this experiment was to find out … (Include background information about requirements for plant growth and plant needs- your textbook would be a good place to begin gathering background information. Include information about the plant or the variable you used to help make your plant go and its importance in this experiment. Include background information which you might have used to develop your hypothesis.) • The control in this experiment was to see if the project with vinegar water. • The variable in this experiment was vinegar water
Materials • Materials • Plastic cup • super growing pellets • Triple beam balance scale • Sunflower seeds • Water or 10% vinegar water • Ruler • Data sheet
Methods • Add super growing pellets to cup. • Add 3 tablespoons of water to expand. • Plant 3 seeds per cup. • Weigh cup on triple beam balance. Record weight. • Add tap water or vinegar water to cup. Weigh again and record data. • Cup will be placed under grow light. • Observe the container daily and note any indications of growth(by observations and measurement) and compare to other containers in the experiment. While observing indicate any special care given to the plant. (Did you need to add more or less water? Did you need to rotate the plant?) • Record observations, measurements, and comments in the plant growth diary. Once the plant begins to grow, you will need to draw a detailed picture of the plant including the appearance of leaves and stems. • Each day , repeat steps 3 through 8.
Scientific Method • Ask a Question • State Your Hypothesis • Identify Control & Variable • Test Your Hypothesis • Collect & Record Your Data • Interpret Your Data • State Your Conclusion
Ask a Question • The purpose of this experiment was to find out … (Include background information about requirements for plant growth and plant needs- your textbook would be a good place to begin gathering background information. Include information about the plant or the variable you used to help make your plant go and its importance in this experiment. • My question: why wouldn’t it grow with vinegar.
State Your Hypothesis • If I plant a sunflower seed it wouldn’t grow because of the 10% of water
Identify Control & Variable • By putting in tap water and the variable is acid water
Test Your Hypothesis • If I add vinegar water to my sunflower seed, then it will not grow because of the acid in the vinegar.
Collect & Record Your Data • (Insert your data here, including any pictures, drawing, graphs)
Interpret Your Data The results showed that the vinegar water didn’t make it grow. • As part of this experiment there may have been variables or scientific errors that could have affected the growth of the plants and the outcome of this experiment. The variables affecting the results may have been that it had too much waterScientific errors that could have occurred and affected the results include 10% vinegar water.
State Your Conclusion • The results of this lab did support the initial hypothesis is Some things that were learned from this experiment were it would grow if it has vinegar water in it. This experiment could be extended in the future by if id put water not vinegar water.
