The control in this experiment was to find out if the vinegar would grow better than the tap. The variable in this experiment was

Introduction

Materials

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

Methods1. 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.

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: How come the plants grow at different speeds it’s the same thing.

State Your Hypothesis If I plant a sunflower seed it will grow at

a much faster rate than that vinegar water.

Identify Control & VariableThe control is the Tap water

The Variable is the vinegar water.

TEST YOUR HYPOTHESIS

If I add Tap water to my sunflower seed, then it will grow at a much faster rate then the vinegar water. because the vinegar water is a substitute for acid rain water.

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 )

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.)
