- During this last double lesson I have gathered information about point number seven from my Investigate. I have now concluded this point that was to gather information about 2-way communication. I collected information from the following websites:
- http://en.wikipedia.org/wiki/Radio_frequency
- http://en.wikipedia.org/wiki/Mobile_phone
- http://en.wikipedia.org/wiki/Walkie-Talkie
- http://na.blackberry.com/eng/services/internet/
With these four weblinks I have been able to obtain information about communication at sea, related to the signal and frequencies. In particular, I researched about cellular phones, Radio frequencies, Blackberries, Walkie-Talkie and Propagation distances. I will 
use this to create my future communication at Guincho beach.
Now, to finish my project I will only have to wait for Danny to go to the Guincho beach to collect imformation about the contacts of the lifeguards, as he has offered himself to do so.
