da Vinci was a great inventor he made machines that could go through air water and land. For example he sketched the first submarine, also he sketched flying machines, also he made the first tank. da Vinci had many great skills like building and drawing, I hope to study him and be able to improve my drawing and building skills when the armored car is being built I hope to only use materials that were available to da Vinci. Although I am a little concerned about David and I, I don’t think that time is going to be enough for us to build the armored car so instead we might make a collage or something of the sort.

I mentioned that da Vinci made the submarine sketch so here is a link to a web-site with the information.

http://didyouknow.org/submarine.htm

Now this web-site may not look to good it might not look trustable. But there is always some ways to check if the web-site is trustable. First always poke around and look at some other things that you might know if the facts are wrong then they are not facts.

Two: Always double check the info with another site if they coincide then they are probably right, if they don’t then one of them is wrong.

Three: don’t always trust wikipedia.org this is because anyone can post there.
