Good science/engineering programs for a current junior (preferably abroad)

<p>Does anyone know of any decent summer programs in the areas of science/engineering? I'm trying to differentiate between the moneymaking "scam" programs and the programs that colleges actually like to see on an application. Also, I currently live on a US military base in England, so it would be logical to find an overseas program in England/Germany sponsored by a US university/organization. Any ideas?</p>
