Also, I've made some slight changes in my method and stuff, but it doesn't really affect anything. So, yeah!
This would be classified as my final blog? It's done and done!
Hopefully there isn't anything else I need to add in this blog?
So, here's the quick update! I've practically finished my report, I'm just adding finishing touches right now! And here are some photos of my experiment. The first picture is the before and after. And the second picture is just a collage of each individual square.

My, my, my!
It has been such a long time since I've even touched my computer! So here I am, posting all the blogs that you haveunfortunately been missing out on...
Just a quick update!
My experiment is close to finishing! (YAY!)
I just need a little longer, and then I can get on to the hard stuff. (This should be fun!)
Well, my results haven't really gone to plan, but what can I do about it? I was expecting something more dramatic... But no, I guess most of the results were similar.
Once I get my information in table/ graph form, I'll consider revealing it to the world..
So, yes. The stress is piling on, as there are 10 days left until our final report is handed in. Yikes. I really am worried.
And here's the perfect word to describe it; ASDFGHJKL.
Alright, that is all for now! I hope everybody else has done much more than I have.
It seems I have come face to face with my old friend, Stress :)
Ahh well.
back to the lab i goooo!

Well, I finally caught up with Ms Zhang today! It’s been a while. I haven’t had her/seen her in quite a while. Whenever I visit the science staff room, she was always gone! So, Luckily I caught up with her today. And she gave me the healthy tick of approval.
I already prepared my method before this, I did it all in advance, I was just unsure before, that’s all. So here is my method, which still needs some improvement, but it’s a start, right?
Equipment:
- 3 sheets of plastic (for this, I used a plastic file sleeve)
- 10 different brands of black nail varnish
- A golf ball.
Method:
1. Draw ten 7cm by 7cm squares on the plastic sleeves. (use a permanent marker pen to draw the squares) Make sure that they are evenly spaced out; leave approximately 3-4cm gaps between each square.
2. Paint a layer of black nail varnish within the 7cm X 7cm square.
3. Repeat step 2 with nine different nail polishes.
4. Leave the nail polish to dry over a 10-24 hour period.
5. Using a ruler, drop the golf ball 3 times (50cm above the ground) onto a painted square.
6. Repeat step 5 with the remaining squares.
7. Measure how much varnish was chipped off. (Use percentages/ratios?)
8. Discuss and analyse the data collected.
Oh, I really hope this is ok for a start? I might make some changes later on. But this is just the basic structure, I guess. I was also thinking, the other day... Maybe I could also test the strengths of the nail polishes if I repeated this experiment, but paint a layer of clear varnish on top... ? I am not entirely sure. I don’t think I should do that, because it would totally change the whole point of the experiment. I hope this is ok for now. I’m off to buy more nail polish.
Oh, and also, if I don’t end up finding enough different brands of black nail polish, I’ll resort to a colour of similar shade... like a dark brown or red. I don’t know, we’ll see!
Behold, my extravagent climate graph! *insert loud jeering* Well, not really. I really wanted it to be scanned in colour! But I don’t know how to function the school scanners properly! It’s sad, because My arm was throbbing from colouring in the graph. And also, for the temperature, the lines are different colours.
I’ve started with painting my plastic sheets. Hopefully, i’ll get my golf ball ASAP, so I can start dropping, measuring and calculating! How Fun! I would upload photos of my progress, however, I don’t have access to my computer right now, and that’s the only way I can upload it! Hopefully, my dearest mother will understand the concept of ‘school work.’
Also, I’ve been trying to find more relevant information on nail polish, specifically on this experiment. Hopefully, I’ll find some good information. For now, I am just reading through the VERY long list of ingredients of these nail polishes! I’m unsure if this is relevant or not, but I’ll just read it for now!

I’m still not sure if my experiment is approved of yet, however I’ve started some progress on this experiment. (I’m pretty sure, i’m okay with this experiment, but I still need to check!)
So, what I’ve done so far is, I bought most of my equipment (which includes: plastic sheets, 4 different brands of black nail polish) NB: this experiment is the reason why I’m currently broke, I forgot that nail polish costs a fair bit of money. I will be starting on this within a few days, I don’t want to be making too much progress and not have it approved.

While thinking through this experiment, I missed one potential factor that could change the results of my experiment. I thought that if I used different coloured nail polishes, the amount of solvent, hardening agents and type of colorants would be a major issue. I then decided to just use the same colour nail polish (but different brands) throughout this whole experiment. I came down to the decision to use black nail varnish.
I’m unsure whether or not the colour of the nail polish affects anything, but I just want to make sure, and make this test as fair and accurate as possible.
I’m unsure whether or not the colour of the nail polish affects anything, but I just want to make sure, and make this test as fair and accurate as possible.
So, I have gone and done some research for this particular experiment. I went and researched the ingredients of nail polish. I found that the ingredients largely affect the strength and durability of a nail varnish. I found out that nail polish has several ingredients, the three main ingredients are: a solvent (dries fast to ensure the varnish dries hard), pigment or colorant (suspends the pigment that is dissolved in the solvent) & hardening agents (makes the plastic harden when exposed to the air. This also helps to trap the pigment in the plastic.)
I also found some useful information here:
Hardeners plasticisers and resins
There are many different nail polish ingredients to make hundreds of different products. The main plasticiser that causes concern is a phthalate. (See below)
Other resins and plasticizers used include castor oil, amyl and butyl stearate, and mixes of glycerol, fatty acids, and acetic acids.
There are many, many ways of combining ingredients to create saleable products with desirable qualities. So many products have huge lists of ingredients.
Nail polish ingredients that cause concern include phthalates (pronounced "thal-ates").
Phthalates are used to keep nail polish from chipping. They do this by having a plasticising effect on the other ingredients.

Now that I’ve made some time over my away-from-home holiday, I just read a little bit about what nail polish is made up of. I found information from books and magazine articles, and of course, the internet (which I so desperately need access to more often) I found this simple information on Wikipedia.
Nail polish has a long history stretching back about 5000 years. It was first developed by the Chinese. They used mainly harmless ingredients such as beeswax, egg white and vegetable dyes.
The ancient Egyptians used henna and other natural products to colour their nails. Only the highest ranking people were allowed to wear bright red nail polish and you could tell a person's social status from the colour they wore.
Modern synthetic nail polishes are a relatively recent innovation.
Nitrocellulose, or gun cotton was developed in the 19th century. It is highly combustible and even explosive but it creates films which can hold other substances in suspension. It is the basis for most nail polishes. It also used to be the main constituent of cine film.
Some early 20th century nail varnishes even used scrapped cine film as the main raw ingredient.

I am still away from home and civilisation, so I have used this time to think about this SRP. I have come to the decision, to do the third idea, which is to test the durability of nail polishes by dropping a hard object on a painted surface to see how much is chipped off.
Because I still need approval from Ms Zhang, if I were to continue with this experiment, the experimental variable would be the type of nail polishes and the controlled variables would be the plastic sheet it is painted on and the amount of varnish applied.
Aim: To find out which nail polish is the most durable
Hypothesis: The more hardening agents in the nail polish, the stronger it is.

So, I was thinking about this SRP right after I got my feedback from Ms Zhang. I realised how confused I was with this whole thing. So, I got home and had a long hard think about it, and now, here I am, with my final decision, and hopefully I have a slightly better understanding of this whole project.
I want to test the strengths of different nail polishes. I’ve thought through many ways that I could possibly test the strengths of the nail polishes. The first method that I considered was to test 15 different nail varnishes, from different brands, on 10 different nails. However, I eliminated this method because the results wouldn’t be accurate.
So, I thought it through, and came up with other ideas. One of them was to paint plastic paddle-pop sticks with 15 nail varnishes, and then soak them in nail polish remover. From this I can test which nail varnish is the strongest, by seeing the amount of nail polish that was stripped off in a specific amount of time.
Another idea was, painting a number of plastic sticks of some sort with different nail varnishes, and rubbing them on different surface. And thus, from this, I can see which nail varnish is the most durable.
One other idea I thought of was to apply nail polish on a plastic sheet, and then drop a golf-ball onto the area, 3 times, and then calculate how much was chipped off. (I would test this numerous times with 10 different nail polishes.)
Hello, well, I was meant to post this a while ago, but I've been caught up, and I haven't been able to use my computer in QUITE a while. I am happy to announce that I have narrowed down my choices for what to do for this labour filled (?) project. So here are the possible experiments, that i may be doing...
1. Testing nail polish strengths.
or...
2. Effectiveness of Blu Tack on holding up a poster in hot dry conditions.
I'd probably do the Blu Tack one, seeing as though the walls of my room are COMPLETELY covered in posters. And I always experience the troubles of sticking posters back on my wall, due to the instantaneous change in weather. It really irritates me.
However.. i really want to test nail polish strengths, because it seems so interesting ♥
So, I'm sorta stumped. But I'll see how it goes, when i further my research with these topics.
I'll just see which one has more background info.
*Kudos to Ms Zhang for the experiment ideas. thank you thank you thank you.
