Temperature and Capacity

I measured temperature and capacity.  

I first did my measurements on capacity I filled up the cylinders with water using 2 large and 2 small measuring cylinders. 

My measurements were 140 ML, 80 ML, 14 ML, and 8 ML. 

After that I did my temperature measurements. I used thermometers to check the temperatures. I filled up 2 lunch boxes hot and cold and measured the temperature. My Tempertures were 12°C, and 30°C.

I need to improve in reading litre because it looked like 36 ML instead of 30 ML.
