Final Method inc. variable etc.

Equipment
1. 3 ice cube trays
2. water
3. timer
4. cooking set with measurements
5. Plastic lids

Method
1. All 3 ice cube trays were cleaned out
2. Each compartment was filled with 7.5mL of water
3. All 3 ice cube trays were put into the freezer at the same time
4. A couple of hours later, all three were taken out at the same time
5. Two ice cubes from each different size was put onto different plastic lids
6. A third ice cube from each different size was also taken out and the surface area of each was measured and noted down.
7. The time was noted
8. Every hour a picture was taken to record results.
9. Step 7 was repeated until the ice cube was almost finished melting.
10. Once the ice cube was almost melted, the total time for the ice cube to melt was recorded
11. Once complete all equipment was washed and put away.
12. All results were documented and recorded
13. A table was drawn up determining if the surface area and shape changed the rate of the ice cube melting.

How the variables were controlled:
1. All ice cube compartments were filled with 7.5mL of water ONLY
2. Two of each ice cube was used to determine the average rate of melting
3. All ice cubes were put into the freezer and taken out at the same time
4. Any water spillages were cleaned up with a cloth
5. Ice cubes were placed on plastic lids so as not to melt on tables
6. All ice cubes were placed in the same room so that the temperature of the room didn't changed the results

Freezing the Water

I have just washed the ice cube trays that I'm going to use so that there is not dirt or foreign material inside the trays.
Also, I have measured and found out that each of the trays easily holds 7.5mL of water each. That is one variable that is being controlled.
The temperature of the water was not able to be found as the thermometer did not work.
The weather today is cloudy and medium rain. I will put the ice cube trays into the freezer after I measure 7.5mL into each compartment and then after a few hours I will take it out.

Photos

I have no idea why but the photos did NOT upload !! ==
I'm going to try again.
Ok so the photos are of rounded and harsh square shaped cubes and long semicircular sticks

Starting

I have just taken all the ice cube trays out of the packaging and taken photos of all of the empty trays to show you how they look (as my explaining of the trays isn't very good). I will attach all 6 images to this post.

Starting the Assignment !!!!

OK, I'm not sure when this assignment is due, but I started thinking about it the other week and decided I should start working on it soon before it gets too late. Anyhow, today I went and bought all the stuff that I need including:

* 3 different ice cube trays - two of them were square shaped; one had curved edges at the bottom the other one had perpendicular edges i.e. not curved. The last one was a rectangular long shaped ice cube tray - very long but at the bottom it curves like a circle.
* Thermometer so I can measure the water that I'm using for my assignment.
* Measuring Cups - instead of a little measuring cup with 1mL intervals, I bought one of those cooking sets that are measured in spoons BUT it also has how many mL's the cup can hold.

Also I will need to make several adjustments to my Method as my assignment is to figure out if the shape of the ice cube will affect the melting rate NOT if the temperature will. In my next post I will write out my final Method all polished and ready to go !

Climate Graph

Here I shall attach the climate graph. I don't know if i did it right or not but at least i made a stab at it. LOL

Draft Method

OK here is my method for now, if this project is allowed to be done. Anyway here is the draft

Equipment
1. 3 Different containers to hold ice cubes - a rectangular one, a circular one and one other shape
2. Water
3. Stopwatch/timer
4. Small medicine cup with measurement at 1mL intervals

Method
1. Fill three little parts within each ice cube container with about 10ml (can be other) of water.
2. Put each into the freezer noting which one went in first
3. Wait a couple of hours until each is definitely frozen
4. Take each out remembering which one went in first.
5. Once all is out start stopwatch
6. After 15 min - half an hour observe and record the results
7. Check again in an hour
8. Check again in two
9. Repeat step 7 until all ice cubes have melted
10. Repeat steps 1-7 on 3 different days with different temperatures

Variables include:
1. The weather
2. Time of day
3. How much water is put into each little compartment
4. The shape of the ice cube

How the variables are controlled:
1. The experiment will be repeated on three separate days with three different temperatures - once during warm weather, cold weather and cool weather
2. All will be done at the same time of day e.g. 5pm or mid day etc.
3. Same amount of water will be measured and put into each ice cube part to be frozen
4. 3 different containers with different shapes will be bought

FINALLY !!!

OMGSH SO HAPPY

I think I've finally decided on the assignment that I want to do.

YAY hehehe

The topic is: does the shape of an ice cube change how fast/slow it melts?

Climate Graphs thingy

Part I - the main points

This is throughout the whole year right? O_o


Minimum Temperature: 8 Celsius
Maximum Temperature: 25.8 Celsius
Minimum Rainfall: 69 mm
Maximum Rainfall:131 mm

I don't know if this is necessary but I'll still add it in just in case
Month with most days of rain: March
Month with least days of rain: August
Month with most hours of sunshine: November
Month with least hours of sunshine: June
