Sea Turtles

I've been working closely with the Department Of Environment in the Cayman Islands. They have a beach monitoring program to track turtle nests because they were almost extinct from our islands. I was wondering if it would be a good idea to make a science fair project on this and if so how? I'm really bad with coming up with the hypothesis for my projects. I was thinking how sensitive are sea turtles to light? But I need a lot of help with this.

If I can't do this then my back up plan would probably have something to do with the environment like creatng an experiment using wind or solar energy. e.g. Does light intensitiy and temperature affect solar cells. However, I'm not as enthusiastic about that project.

I think that it would definitely be possible for you to come up with a science fair project related to the turtles. But, you are going to have to be careful because, as you say, these animals are endangered. So, you may need special permissions to work with them--I suggest speaking with your teacher about that.

I would also suggest speaking with your boss about the possibility of doing a science fair project, and getting some ideas from him/her. You will probably not be able to determine how sensitive they are to light, for example, since you could potentially harm them in the process.

Could you tell us more about the exact data you are collecting? If you can tell us more, we may be able to help you come up with a question and a hypothesis. In the meantime, I would suggest reading through Science Buddies' guide for completing science projects, here: https://www.sciencebuddies.org/science- ... l?From=Tab

Good luck!

We have a date collection sheet that says:
*Date
*Beach ID
*Crawl Type
*Species
*umm I can't remember the column name but it included the answers of a false crawl attempt, a potential nest or a nest.
*Shaded?
*GPS mapping
*Triangulation mapping
*Date layed

I was watching a video on the internet saying that different temperatures could cause a different sex ratio. I was thinking of doing a project on that but then again these are endagered species or I would just disect the dead babies turtles to find out their gender or something like that. But if that wasn't possible then I was thinking of doing it on a different species. Do you know any other species that can do that? Whichever would be easier. Or I would just think of a different hypothesis all together.

Hi! Since you are enthusiastic about the sea turtles, I would focus on finding a good project on that topic, instead of the solar ideas you have. I am sure we can help you do that.

As you realize, since they are endangered species, we don't want to do any experimentation that will cause stress on the animals and possibly affect their survival in a negative way. Since you are working witht he DEC there already, have you tried to dicsuss this with yor contact there to see if theyhave any ideas you can pursue? They may have something that is already integrated in their current reasearch program.

Another idea is, instead of studying the turtles themselves, perhaps study something the turtles leave behind and don't use again - like their nest in the sand or their leftover eggshells. You could ask a question such as "does clutch size affect the number of hatchlings?" and collect data about clutch sizes (egg #s) and hatch rate for comparison. I am not sure if their nesting and hatching schedule is in line with your prohect due date, so you will have to think about that.

I will see if I can think of anything else to give you ideas.

Do you have access to the completed forms? If so you can analyze whether there is a trend of the beaches where you find the most turtles. Do the turtles prefer some beaches over others?

Yes. I do have access. Sometimes I even fill them out. So most turtles prefer to go on one beach than the others.

They don't have any ideas I would like to do. I like the clutch size/hatch rate idea too.

Thank you all for your help so far.

Hi groberts00 -- I saw your post and the advice already offered by our Experts as you work toward a project, and I talked with one of our staff scientists a bit to see if she had some additional advice for you. She did! I'm posting her reply below. She's offered some great input in terms of resources to check on the Science Buddies site as well as some specific help in terms of where you are in the process of designing your project.

Here is her response to your query here at Ask an Expert:

It looks like you're in the idea position to conduct a fantastic observational science project. I say "observational" because as you and the others have all commented, interacting and manipulating these sea turtles is likely to be forbidden given that they're an endangered species. But you can still collect a lot of information about them and use that information to look for trends and correlations. I have a couple of suggestions to get you started on your process.

1) Given your age (6th form) and the amazing opportunity you have to gather some cutting edge data, you could work towards an advanced science project that you might be able to enter into some of the world's top science competitions. The Science Buddies Advanced Project Guide [https://www.sciencebuddies.org/science- ... ndex.shtml] has a wealth of information for you. Most critical at the moment is the Roadmap: How to Get Started on an Advanced Science Project [https://www.sciencebuddies.org/science- ... dmap.shtml]. You're already on Step 3: narrowing your idea (learning more about sea turtles) into a testable question and hypothesis. So go read this section and the roundtable discussion from other students on "Finding an Idea for an Advanced Science Project" [https://www.sciencebuddies.org/science- ... 2008.shtml]. What you'll notice is that one of the key things is finding out more about what has already been published about sea turtles. As you do this, you'll also learn what isn't known....and that will lead you to a question and a hypothesis.

2) As we already stated, your project will be "observational." Here is a summary of the different types of observational studies: https://www.sciencebuddies.org/science- ... tion.shtml. There is a long, and noble, tradition of observational animal science research. Jane Goodall's famous work studying chimpanzee social structures in the wild is an excellent example! Here are two Science Buddies' animal observation studies which may help to give you a general idea of how to structure your project and thoughts: Bat Detector: Listen to the Secret Sounds of Bats [https://www.sciencebuddies.org/science- ... p024.shtml] and Where, Oh Where Do the Wild Wolves Wander [https://www.sciencebuddies.org/science- ... p056.shtml].

3) As I mentioned in point #1, reading the literature is really what is going to help you figure out a question and hypothesis. But I really like one of the ideas you came up with: dissecting the eggs that fail to hatch. Perhaps you could look in the literature to see what has been published about why some eggs hatch and others don't. What is known to effect that? Temperature? Location in the nest...i.e., middle vs. edge? Number of eggs laid? What is "wrong" with the ones that don't hatch? Are they fertilized? Do they start to develop? If so, at what point do they arrest? Is there a trend? A particularly vulnerable window of development? Do they appear to be normal and arrested, or do they have physical abnormalities? There are a lot of questions here. Look at the literature, see what has been discovered already, and then use that to develop a more focused question and an outline of what you'll need to answer the question.

4) As you move forward don't hesitate to reach out to scientists to ask your questions. This forum is a good resource, so are the researchers you're working with (and they're more likely to know specifics about sea turtles). As you read the literature and focus in on a question you might find that one particular researcher's work is central to your project. You can try to contact them too. Or if you get involved in dissections etc. reach out to developmental biologists who might be able to help you identify what you're seeing. Remember, science is collaborative - it is important to go out there and ask people what they know. Be respectful, but don't hesitate to ask. Some people might not have time to help; but if you keep reaching out you WILL find a great mentor.

Best of luck - I really think you have an amazing opportunity in front of you and you may be able to make a novel scientific contribution to sea turtle biology and conservation!
I hope this helps! I look forward to seeing what direction you take with the project. Our Experts are here to help as you move forward.
