Look at the pictures of Posh below - what differences can you see? What could cause these differences?

The main differences seen (except hair colour) is that her hair length and her weight vary greatly in the pictures. These features are affected by environmental factors
**be careful with hair colour - this is inherited, however we can temporarily change its appearance using dyes

Characteristics of animals and plants can be affected by factors such as climate, diet, accidents, culture and lifestyle
If you eat too much you will become heavier, and if you eat too little you will become lighter
A plant in the shade of a big tree will not be able to photosynthesise as quickly as one in the sunshine, so it will be smaller
Variation in a feature as a result of the surroundings, is called environmental variation

Variation & VarietyVariation & Variety Variation can occur within a species (i.e. some people have
blue eyes, others have brown eyes)
A great amount of variation also occurs between species (i.e. guerillas are generally hairier than humans)!
Your task is to look at two different species of potato, and identify some characteristics (e.g. size; colour; mass). You then need to identify how these characteristics vary between the two species, i.e. how does colour vary between the two species? how does size vary between the two species?
Once you have decided on the characteristics you are to measure, design a results table in your book…

Species Characteristic 1 (e.g. colour)
Characteristic 2 (e.g. size)
Characteristic 3 (e.g. mass)
Potato species 1
Potato species 2
Remember, look at a few examples from each species so you can record an accurate representation of that characteristic
The write a conclusion in your book, identifying how one species is different from the other.
Why do you think this variation exists (have you collected enough data)?
