My Scientific Fair Test Investigation
Áine Reynolds Carroll
A fair test investigation
see video above for a further explanation
what is a fair test investigation?
A fair test investigation is a controlled experiment which is carried out in order to test a hypothesis or a prediction about a certain event. A fair test only changes one variable and keeps all other variables constant.

the experiments
we completed two experiments
  1. does temperature effect the rate at which an ice cube melts ?
  2. which material works best as an insulator ?

predictions ??
Ice Cube Investigation
Investigation no. 1
how long does an ice cube take to melt in a room temperature setting?
equipment needed:
  1. chronical flask
  2. thermometer
  3. ice cubes
  4. fridge

steps in the Investigation:
  1. freeze water in a ice cube maker.
  2. collect the frozen ice cubes.
  3. place the ice cube into the chronicle flask.
  4. use the timer to record the time it takes until the ice cube has completely melted in room temperature.
  5. also record the time it takes for an ice cube to melt in a fridge.
  6. record results.

The ice cube melted quickest in the room temperature setting.

It took longest to melt in the cold fridge setting
insulation investigation
investigation 2 : which type of material will insulate Guzzlers hot chocolate?
equiment needed:
  1. thermometer
  2. cotton wool
  3. tinfoil
  4. coffee cups
  5. rubber bands
  6. timer

steps in the investigation:
  1. using a kettle, boil some water
  2. measure the same amount of water, using a chronical flask and seperate into three different coffee cups
  3. insulate 2 cups with tinfoil and cotton wool and secure with rubber bands, leave one cup insulation-free
  4. record the temperature of each coffee cup with a thermometer at the beginning
  5. continue recording the temperature every 2 minutes until you have reached a total of 10 minutes
  6. compare results and conclude as to which material acted as the most effective insulator
