I have finally finished my SRP report that I have put so much work and effort in. I went to the library yesterday to do some research and find some books that gave me more information on water evaporation. It was quite helpful. I found parts of my report a bit challenging, especially when I had to repeat myself in the different sections. The sheets and past reports were very very useful because I always referred to them when I had trouble and they acted as guidelines when I was stuck.
Now, I will go and print off the report and have it ready for tomorrow. Looking back, I'm glad that I spread it out and didn't save it until the last minute.

I've finally finalised and completed the practical part of my experiment. Now, I need to put the photos up and start my SRP Report. I really don't know where to start, this is so muddled up. I'm going to go and write everything that I know first, and then tackle each section down one by one. Hopefully, Ill make some progress!

Okay, so re-posting my method. I had it written out last time, and there wasn't many things wrong with it. I'll just touch it up according to how I did it. Also, my first experiment was alright. I'm not sure if I did it correctly with the correct timing/procedure/placement of containers etc. etc. So I'm going to do it again over the next week or so, and then maybe a third time round? I also took a few photos, which will probably be up soon.
Anyway, here's the method:
1. Pour 250mL of water into container
2. Cut out a 30cm x 30cm sheet of plastic.
3. Place plastic over the container and securely wrap it around all edges
4. Clearly label your container
5. Wait 4 days
6. Take off sheet of plastic and measure the amount of water left in container
7. Record observations
8. Repeat steps 1-6 with the different brands of plastics

Yes! I was fiddling around with the timezone and I think I finally managed to get it right. Let's hope this turns out to be like 7:30pm ish. :)
I managed to finish my climatic graph last night, yay! I decided to hand draw it and it didn't take long at all! My scanner is having problems with itself these days, so I just took a photo of it. Let's hope this turns out okay:

Woops. I just realised I made two mistakes in my experiment.
1. I had initially forgot to label my containers with which plastic wrap was on which container, and when I had gotten around to doing it I have a feeling I got confused with a few of them and labelled them wrongly.
2. I found a little crack in one of my containers.
Guess that didn't go well. I'm starting it up again soon, and this time I hope I remember eveything I forgot.

During the time my containers are sitting outside, I'm regularly checking them about every 6 hours to see if the level of water has changed in the containers. So far, nothing dramatic has changed enough for me to write anything, but I can see that little condensation bubbles are appearing on the inside surface of some of the plastic wrap.
In this time that I'm waiting, I've been doing some research on water evaporation to make my understanding of this experiment more clear. "Evaporation continuously moves water from the surface to the atmosphere." So in this case, because the atmosphere is blocked by a layer of different brands of cling wrap, it would change the process of evaporation.
Evaporation is when water is changed from liquid to a form of gas. This change requires heat, and is called the "latent heat of condensation". When water evaporates, it removes heat, lowering the temperature of the surface.

The amount of water evaporated from a certain place depends on the temperature in the water and air and the humidity and velocity of the air above the surface.
Maybe.. I should have placed my containers by the window so evaporation would occur faster? But then it wouldn't really be a fair test, because they would get different amount of sunlight and each day would not have the same amount of sunlight, too. I'll just leave them where they are and see how this goes.
