Re-reading the criteria


Yes, I am re-reading the blog submission right at this hour, checking that I have met it.
I have my climate graph, and I have remained somewhat active on my blog, mind you I did go away to New Caledonia, and I will re-visit my method in this post, half of it anyway.

My method, as previously posted, will be starting hopefully this weekend.
I have finally bought the food colouring but I am unsure whether I should buy more than three different types of dye. I currently have two fabric dyes, RIT and Dylon, so I am still thinking about which one to use, or maybe to use both. I may use organic dye or ochre as my fourth and fifth dyes for the experiment.

As for my method, with my equipment being all fully purchased by end of this week, I should be able to attempt my first lot of the experiment.

This is my plan so far; with notes here and there:

Aim: To investigate which dye is the most effective in dying eggs.
In the experiment, I will change various factors such as length of time period soaked in the dye, as well as the type of concentrate the dye is in. At this point in time, with some further research, I will be adding substances such as lemon juice and water to the dye to see the effect on the dyeing process.

Equipment:
Fabric dye
A dozen eggs (hard boiled)
Food colouring
Lemon juice
Water
Plastic cups
Glad wrap
Organic dye
Ochre dye

Method:
1. Collect all equipment
2. Set up equipment as follows:
- One egg per cup, one type of dye in each cup
- Make sure cups are labelled with a sharpie as to which dye it contains
3. Place all equipment in the same conditions, preferably room temperature, possibly consider placing one in the sun to change variable?
4. Record all observations.

Now, obviously this is just a draft of my method, and it will need to be revised again later today.
