1 SUNFLOWERS AND ACID RAIN Talent 21 Project By classy Bordley Date may, 7 Period 5

2 INTRODUCTION  The purpose of this experiment was to find out if the sunflower seed grow.  The control in this experiment was tap water.  The variable in this experiment was vinegar water.

3  Materials  Plastic cup  super growing pellets  Triple beam balance scale  Sunflower seeds  Water or 10% vinegar water  Ruler  Data sheet MATERIALS

4 1.Add super growing pellets to cup. 2.Add 3 tablespoons of water to expand. 3.Plant 3 seeds per cup. 4.Weigh cup on triple beam balance. Record weight. 5.Add tap water or vinegar water to cup. Weigh again and record data. 6.Cup will be placed under grow light. 7.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?) 8.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. 9.Each day, repeat steps 3 through 8. METHODS

5 SCIENTIFIC METHOD  Ask a Question  State Your Hypothesis  Identify Control & Variable  Test Your Hypothesis  Collect & Record Your Data  Interpret Your Data  State Your Conclusion

6 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 did some people plant grow and we did it on the same day.

7 STATE YOUR HYPOTHESIS  If I plant a sunflower seed  Then it will not grow because the seed does not get enough sunlight.  Because the seed need the acid rain water because that’s how plants normally grow.

8 IDENTIFY CONTROL & VARIABLE  The control water is the tap water. The variable is the vinegar water that we start off with.

9 TEST YOUR HYPOTHESIS  If I add tap water to my sunflower seed, then it will not because the plant need to take acid rain water.

10 COLLECT & RECORD YOUR DATA  (Insert your data here, including any pictures, drawing, graphs) dayDry Wt.Wet Wt.Difference day 159.4949.1939.47 day241.49091.49 day372.382.14.8 day477.880.30 day565.6570.453.8 day668720

11 INTERPRET YOUR DATA  This is where you put your analysis. The results showed that (Describe general trends from your data)  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 (Describe any variables in your particular experiment.) Scientific errors that could have occurred and affected the results include (describe – for example used the wrong type of water )

12 STATE YOUR CONCLUSION  The results of this lab (did/did not) support the initial hypothesis (explain why you think this was the outcome.) Some things that were learned from this experiment were (identify what you learned without using first person) This experiment could be extended in the future by (identify an investigation that would be a natural next step based on your results.)  Add Graphic
