I HAVE DECIDED. THIS IS FINAL!!!

The title well states it already.
Which Tropical Fruit Will Survive In the Hottest Conditions?

So I am going to use 5 different tropical fruits for this experiment (10 of each fruit)
- Mango
-Banana
-Lychee
-Lemon
-Pineapple
-Kiwi ( as a spare alternative)

I am going to leave these fruits out in the sun for a number of hours. I am going to take before and after diagrams of the fruit with the exposure of the sun. I am going to see if it has gotten softer/harder after the sun, turned a different colour. The tropical fruit that is least effected will be the ''winner''.

It is hard to keep this consistent at times however I am going to try as hard as possible. I will buy all these fruits on the same day and start the experiment the following day. I will go to Centennial Park, where sunlight is plenty and leave it in an area where sun light is fully exposed (without any shade at all).

I will observe it like this: fruit after 2 hours of sun, after 4 hours and over 6 hours. Its changes will be recorded. I think this might be not too complicated so if Ms thinks its too easy then I will rise the difficulty of my analysis. I might include tasting it, e.g. if the fruit changed in taste, turned sour, or flavourless due to heat.

As emntioned before I am buying 10 of each kind of fruit. So altogether basically 50 fruits =)

Nope.... I Havent Forgotten About This!!

Heyy everyone =) I've been thinking  more and more of my SRP. I think if I had food wraps then I wouldnt have to buy so much equipments as I have them already (household supplies). However, If i use nail polish then I'll have to buy different removers and different nail colorus and also acryllic nails.

Those 2 ideas are completely not revelant to each other, so Im still deciding to do food science or nail polish/chemical reactions.

Another Idea To Share =)

Aim: In what conditions do nail polish removers work best with nails?


Independent: Different brands of nail polish remover (with different amounts of acetone), different colours of nail polish and different applicators to take it off (e.g. cotton bud or cotton wool).

Dependant: the number of coats each nail polish is applied on (2 coats for all nail polishes), the temperature at which its applied (room temperature), the length of time from the nail polish applied to the nail polish removed (1 day after its been applied).

Controlled: The experiment will be conducted on my acrylic/ fake nails.

Method and Other Thoughts..

Okay.  This is like a continual psot from my previous idea about food wraps.

I think that the following variables should be controlled in this experiment:
- the size of each food wrap
-the food itself should be consistent(e.g. meat or fish)
-the length of time that each food is left in a frost-free environment (e.g. 2 or 3 days? before it goes off and become unfresh).

I also have a sketchy method in my mind:
1) go to supermarket and buy cling wrap, foil wrap, paper bag and a plastic wrap (e.g. fitted palstic bag)
2) cook some dinner with meat and scoop leftovers in 4 different plats wrapped with 4 different food wraps.
3) make sure it is away from a frost-free environment and leave it there for 2-3 days
4) Observe the freshness of the meat by smelling (if it went off) or observing moles forming.
5) Repeat experiment using fish
6) Then continue experimenting for the next 6 weeks alternating between fish and meat.

I know the above was suppose to be written in past tense form and in parag. I'l be editing my method for my atcual experiment. Which I'll probably start on soon!

Further Update!

Hey.

So SADLY I have discarded my ideas from Thursday. The apple concetration one, was tempting to do, however I did not have the right equipments nor could I obtain those easily.

Good side is I'm going to do soemthing, I might change BUT so far:

Which food wrap keeps food fresher in a frost - free fridge?

Some food wraps include:
-cling wrap (palstic wraps)
-foil wrap

Plastic wrap was first made from PVC, which remains the most common material. Not only am I comparing the types of wraps BUT also the different brands of wraps in each kind.

Hope my expeirment will work!

Further Investigation on My SRP

Hey everyone. Its Thursday afternoon, and I'm thinking on ideas for my SRP. I've kind of abandoned the idea of doing plant related research. However, I've come up with some other ideas e.g.
 
- Do all brands of orange juice contain the same amount of absorbic acid?
- How does the sugar concentration vary in different brands of Apple Juices?
- Do different types of orange juice contain different types of Vitamin C?

AS you can see, all 3 ideas relate to liquid/juices. I might be doing ideas 1 OR 2. I'm not sure yet, as I have not thought of a method for my experiment yet.

Ms Zhang, if you're reading this, are these ideas too easy? do they meet with high school standards?

Going to finalise my decision and update soon. !

Ideas for SRP

Hi everyone. I've started researching for some experiments to do. Right now, I've been looking in the area of biology e.g. growing plants and also food science (such as testing out certain food and how fast it takes it to rot or grow moles). I'll update soon, still looking!
