Question

Explain how would you use the scientific method to determine the effect of acid rain one sprouting of seeds?

Answer 1

First make a hypothesis: If acid has a negative effect on the plants, then the plants will die.

Second make a list of materials you'll be needing for the experiment.

Third, make a procedure. The procedure is supposed to be a step by step guide telling people how you did your experiment and how they can try out your experiment too.

Your procedure would propbably be something like this, but with a lot more finesse and better wording:

Grow four plants of the same size, species, and age. Get some kind of simply plant (ie: gerainium[spelling's off, but read it out and you'll be able to get it]) that's easy to take care of and that doesn't thrive in acidic conditions.

After making sure the plants all have the same environmental conditions (ie: same amount of sunlight, temperature, soil quality), water two of your plant specimens with DISTILLED water (not water from the tap!! Water that DOESN'T have chlorine and other chemicals floating around in it). Water the other two plants with a bit of hydrochloric acid mixed in with water. Use seperate watering cans to avoid contaminating your experiment. You can start at a low concentration of acid in your water to see how your plant adjusts to the acid intake. Record your findings.

Another way to go about this would be to start growing several plants at once and giving each a higher concentration of acid water. If the plants die faster as the amount of acid in the water goes up, then you just proved your hypothesis.

Fourth step is to record your observations. Write down any changes in your plants. Make sure you record which plants did what.

Fifth step would be to analyze your findings. Here you would ask and try to answer questions you could encounter when taking a look at your observations: for example, did your plant really die because it was being watered with acid or did it die because it didn't have enough sunlight? <---Try to reason out why things happened like they did.

After that, cite your sources of error. Since people tend to be people, they make mistakes and thus no experiment performed at a highschool level is absolutely perfect. List all the things that you might have made a mistake on, for example: maybe you weren't always precise when measuring the amount of acid poured onto each plant. Maybe you forgot to buy distilled water and used tap water instead (tap water being filled with chemicals to keep the water clean might have been dangerous to your plant).

After citing your sources of error, write up a conclusion. Basically, you say your hypothesis was either right/wrong, and list the reason why you're right/wrong. There's many ways to write a conclusion for scientific papers, and a quick search on the internet will be able to give you an idea of how to do it properly.

WARNING: Hydrochloric acid is the nastiest acid out there and can give some major burns. ALWAYS add the acid into the water. If you pour water onto a lot of acid, the water will boil and splash acid water onto your face = not good.

Good luck! Sounds like a fun experiment.

Answer 2

It causes them to be super powered mutants.

Answer 3

You must determine your hypothesis to answer this question.

Use the visual organizers to help you write the steps.  It is easy this way:

1-Ask a Question

2-Do Background Research

3-Construct a Hypothesis

4-Test Your Hypothesis by Doing an Experiment

5-Analyze Your Data and Draw a Conclusion

6-Communicate Your Results

Another way to express it:http://www.makeitsolar.com/science-fair-...

1. Identifying a Problem

2. Forming a hypothesis

3. Designing and Performing Experiments

4. Collecting and Analyzing Data

5. Formulating Conclusions about the Hypothesis

You have a big project.  More detailed than what you can expect from Yahoo! Answers.  Good luck!
