Hi Antoi,

Thank you for writing to Education.com.  There are many choices of projects that your sixth grader can choose from!  

http://www.education.com/science-fair/ has many science fair projects ideas and advice for how to complete a science fair project.  

The broad term â��evolutionâ�� can take on many meanings.  Do you mean the evolution of a species (genetics), the evolution of the world around us and the environment, or do you mean the evolution of mankind as a whole?  For example, some animals have evolved to adapt to the world around them so they can better survive in a given environment.  An example of an adaptation is being able to camouflage with the environment so predators would be less likely to find prey.  

Below are science fair projects you should like at:
