This week i had to design my experiment, organise the equipment and set the controls for my experiment. I also had to identify the dependent and independent variables.
These included:
Dependent- time it takes for the chocolate to melt
independent- the quality of the chocolate (brand and flavour)
controls- amount of chocolate and temperature of the water (boiling point/100 degrees celsius)
The aim of my experiment is to find out what type (brand and flavour) of chocolate melts the fastest at boiling point.
Equipment: thermometer, tooth pick, stopwatch, Bain marie (a pot of water and bowl can be used if a Bain marie can not be used) and a stove.
I will be taking photos to show that I conducted my experiment and will being using a table to collect my results.
Some safety precautions that I had to be aware of were:
-being very carful around a hot stove and a pot of boiling water
-being carful not to burn myself when testing if the chocolate is melted using a toothpick
-being carful not to burn myself when testing the temperature of the water before putting the chocolate on
