PRoject with Arduino and BMP180,TSL2561

Hello to everyone i am making a sketch with 2 sensors BMP180 and TSL2561, when i use them separeted it isn't a problem but when i use them both in one sketch i can't because my Arduino Mega 2560 has only 1 SCL and 1 SDA, how can replite these exits to use the "virtual" ones on the other sensor?

You can connect multiple sensors to an I2C bus, provided that they have different addresses. Some I2C sensors can be configured for specific addresses, by jumpers or software.
