Hot & Cold

 Wednesday 17th of March was my photo day and the year 7/8 Tech day. Since I was in Science we did an experiment. The experiment was based on temperature and degrees. Here are the instructions:

Fill the measuring cylinder with cold water up to 50 ml then pour it in the beaker, do this once more. Once the beaker is filled all the way up to 200 ml, put the thermometer in making sure it does not touch the bottom of the beaker. the temperature Charles and I got was 25.5 degrees. write the number you got on to your book then continue. Grab the weighing scale, put the petri dish on and weigh 10 grams. Once done get your partner to time how long it will take for the sugar to dissolve in the cold water with the stopwatch while your mixing it. Our time was 1 min 9 sec. When we did the same thing to the hot water our temperature was 80 degrees and time was 30 sec. Time difference - 39 sec
