Using Multiple Thermocouple on Arduino [HELP!!]

my lecturer gave me a task to make a microclimate data logger to monitor the temperature and RH condition inside the greenhouse, he asked me to use thermocouple for the sensor. I managed to find a tutorial with using max6675

http://henrysbench.capnfatz.com/henrys-bench/arduino-temperature-measurements/max6675-temp-module-arduino-manual-and-tutorial/

but the problem is he asked me to using 60 sensors, on that tutorial it using pin SDA, SCL that only one port exist on each arduino board. and If i use the I2C protocol is it possible to use the multiple max6675 on a same board??. and how can I do that ?

Thanks, really need help!!
