Yes due to lack of time and shifting our home now, my mom recommended to take the project I have already did and make enhancements to it.
I took this project idea from the below link
http://www.virtualsciencefair.org/2010/zhenxm2

Based on that please let me know if the below information looks good or if any changes required.

Title: Using Banana Peels to Zoom Fast

Are Banana Briquettes an energy efficient and eco-friendly Bio-fuel?
(The degree of rise of temperature and the amount of joules of energy for every fuel with Time)

Question: When Banana Briquettes are heated, will it be more energy efficient and environmentally friendly substitute than Coal?

Independent Variables: Time of Observation (in min)
Dependent Variables : Degree of rise of Temperature and the amount of joules of energy for every fuel (coal vs banana briquettes vs co-firing)
Constant: Enviornmental location, amount of water for heating, weight of fuel
Control group: coal

Hypothesis: If Banana Briquettes are heated and measured for a period of time, then the degree of rise of temperature and heat energy is high and hence could be an alternative energy source for coal and more ecofriendly.

Can you please provide me catch title if you think otherwise. I have to submit the science fair project on Jan 18. it is already late :-(

Thanks,
Lakshu
Hey Lakshu,

Okay, now I understand why you switched directions! (I'm sorry that you are short on time; I thought you had a good start on the 1st project :) ). This looks like a solid outline!

As for titles, because it's going to be judged in science fair competition(s), I would suggest a more formal title as opposed to silly/more catchy ones like "An Alternative Energy Source Better than Coal? That's Bananas!".
A more appropriate title would perhaps be in this format: Comparing Energy Efficiency of Banana Briquettes and Coal (or "Are Banana Briquettes As Energy Efficient as Coal?")!

Hope this helped,

JSK

Dear JSK,

Thanks for your mail. I am working on Broadcom. Can you please help me with the below questions.
1. How did you collect your data?
I am writing something as : Data was recorded at the end of each step for 3 individual trials and values were written down as experiment progressed. Information was measured on variables of interest.
Please correct me if I need to provide more details here.

2. How did you analyze and interpret your data?
My answer is : he data recorded was analyzed and interpreted to compare the results observed when heating with Coal vs. Banana Briquettes vs. Co-firing.
Coal showed a consistent increase of temperature with time. The initial rise in temperature was less compared to heating with Banana Briquettes & Co-firing and about the same amount of heat energy was produced. The initial rise in heat energy was less than produced with Banana Briquettes & Co-firing.
Banana Briquettes showed a consistent increase of temperature with time. There was a high initial rise in temperature than using Coal but almost the same as with Co-firing. It produced high heat energy initially than heating with Coal, but almost the same as with Co-firing and then remained consistent.
Co-firing (Banana Briquettes and Coal) showed a consistent increase of temperature with time. There was a high initial rise in temperature than with Coal but almost the same as with Banana Briquettes. It produced high heat energy initially than heating with Coal, but almost the same as with Banana Briquettes and then remained consistent.

3. What lessons did you learn from doing your project? What lessons did you learn from presenting your project?
Can you help me how to answer this question.

Thanks,
Lakshu

Hi JSK,

How are you.. Long time. Now again science fair time and I started my project which we started last year but i switched to another project at the last minute.
I really need your guidance for successful completion of this project. I am doing the below project
"CO2 and Global Warming": http://www.all-science-fair-projects.co ... 121_1.html

I already started the documentation and experiment. Can you please help me with below topics and check if I am right and suggest me if any changes.
Title:
Will an increased level of Carbon dioxide in the atmosphere contribute to rise in Global Temperatures?
(The effect of different levels of Carbon dioxide concentration on the rate at which the temperature of the air cools down in 1 hour)
Question:
When Carbon dioxide levels from different sources like Normal Air, Air from lungs, and Car Exhaust are compared for the temperature variation, will the rate at which the temperature of the air cools down in 1 hour be slower for the high Carbon dioxide level percentage, thus contributing to the rise in the average temperature of the Earth’s atmosphere which results in Global Warming?
Hypothesis:
If Carbon dioxide levels from different sources like Normal Air, Air from lungs, and Car Exhaust are compared for the temperature variation, then the rate at which the temperature of the air cools down in 1 hour will be slowest for the high Carbon dioxide level percentage from Car Exhaust compared to the Carbon dioxide level percentage from the other two sources.
Variables:
Independent Variables: Carbon dioxide source (Normal Air, Air from lungs, Car Exhaust)
Dependent Variables: Rate of Temperature variation (in degree Celsius) in 1 hour
Constants: Environmental location, Initial temperature of the air in the tank, Type of the soil, Amount of the soil at the base of the tank, Volume of the tank

Controlled Variables: Normal Air

Please let me know ASAP so i can start documenting. Thanks so much for all your help you have done so far.

Thanks,

Hi Lakshu,

My apologies, I was just notified of your replies to this thread! Yes, you have a good grasp on this project, and all of the topics you've listed (Title, Question, Hypothesis, and Variables) are correct. My only suggestion (and if you don't have any more time to spare on this project, please do not worry about this minor detail) would be to add some kind of rationale for your hypothesis. Why do you predict that the rate at which the temperature of the air cools down in 1 hour will be slowest for car exhaust?

Please do let me know if you have any other questions/concerns. I apologize again for responding so late!

Hope this helped,

JSK

Dear JSK,

Thanks for your reply. NP for your late response. But glad you are here to guide me. I don't get you how you meant to add Rationale to Hypothesis. I already mentioned, the temperature of the air cools down in 1 hour will be slowest for Car Exhaust (which has the highest Carbon dioxide concentration level). We have separate section for Rationale to mention why I want to do this project.
I added like below:
I wanted to do this project because Global Warming is a highly debated subject. During my research, I found that the rising average of annual temperatures have caused scientists to speculate on the possible causes and consequences. While many scientists analyzing historical trends believe Global Warming is a natural process (Earth undergoing cycles of rising temperatures and periods of cooling), some scientists have correlated rising Carbon dioxide levels to Global Warming. NASA scientists measure Carbon dioxide in the atmosphere and monitor increases in Carbon dioxide levels. As the human population grows, the burning of Fossil fuels increases evolving Carbon dioxide gas into the atmosphere. Rising Carbon dioxide levels is correlated with rising temperatures because Carbon dioxide is believed to trap natural heat caused by the surface warming of the Earth by the Sun. The natural heat usually escapes into space during night time. The Carbon dioxide is believed to blanket the atmosphere and trap the heat causing the Earth’s surface to become insulated and causing temperatures to rise. This project attempts to simulate the processes on Earth and collect data to lend support to see if increased levels of Carbon dioxide in the atmosphere contribute to a rise in Global temperatures.


Please let me know how you want to make change in Hypothesis and if this Rationale makes sense.

Thanks,
Lakshu

Hi Lakshu,

That rationale for why you want to do the project and your hypothesis make complete sense! There was one grammatical error that I bolded in your rationale, but other than that, excellent work!

Let me know if you need any additional help,

Re: Greenhouse gases

Hi JSK,

Thanks for all your help. I have been selected at school level to take to regionals on March 3rd. I have some clarification. there is one thing I realized I missed in conclusion:
I didn't take limitations of this project into account in my conclusion. Can you please help me to write the limitations.

Currently my conclusion looks like:

The purpose of the hypothesis was to check “If Carbon dioxide concentration levels from different sources ( Normal Air (natural surrounding air), Air from lungs, and Car Exhaust) are compared for the temperature variation, then the rate at which the temperature of the air cools down in one hour will be slowest for Car Exhaust (which has the highest Carbon dioxide concentration level) compared to that of the other two sources.”
After the completion of the experiment, it was found that the hypothesis was correct due to the following observation:
The data table shows that the average temperature of the fish tank with Normal air (the lowest Carbon dioxide concentration of about 0.04%) was 24.9°C at one hour. The average temperature of the fish tank with the Air from lungs (Carbon dioxide concentration of about 4%) was 27.8°C at one hour. The average temperature of the fish tank with the Car Exhaust air (the highest Carbon dioxide concentration of about 12%) was 30.1°C at one hour. Hence it can be concluded that the rate at which the temperature of the air cooled down in one hour was the slowest for Car Exhaust (which has the highest Carbon dioxide level) compared to that of the other two sources. Based on the data, it could also be concluded that the rate at which the temperature of the air cooled down in one hour was the quickest for Normal air(which has the lowest Carbon dioxide level) compared to the other two sources.

This experiment simulates the process on the Earth for Global Warming. It was demonstrated that the heat released by the black soil in the fish tank was captured by the Carbon dioxide molecules. Since the tank with Car Exhaust air had the highest Carbon dioxide concentration, the rate at which the temperature of the air cooled down in the tank was the slowest which resulted in the average increase in the tank’s temperature.

Please write to me asap so I can modify my log book and project board.

Lakshu

Hi Lakshu,

I am extremely sorry for the delay! Congratulations on making it to Regionals!!
Your conclusion, disregarding the absence of limitations, looks great. When addressing limitations, always take into account the extent in which the procedures can be applied and how accurate they are, and the materials used and how they limit the degree of accuracy of the data produced from the experiment. You should also keep in mind how reproducible/precise your procedures are.

For your limitations, if you haven't already (again, apologies for such a late response), consider writing on the limitations on utilizing a fish tank as the device in which CO2 levels were measured in, the car exhaust piping, etc. (There are always uncontrollable variables relating to the materials used (ex. can't control the level of car exhaust emitted)). Again, these are some examples related to <i> materials </i> only, but the procedures & their limitations on reproducibility + accuracy should also be noted.

Hope this helped,

JSK
