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

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!!
