At what temperature does chocolate go from a solid to a liquid? Is it different for white and dark chocolate? Give this fun science experiment a try and find out!
What you’ll need:
lSmall chocolate pieces of the same size (chocolate bar squares or chocolate chips are a good idea)
lPen and paper to record your results
lPut one piece of chocolate on a paper plate and put it outside in the shade.
lRecord how long it took for the chocolate to melt or if it wasn’t hot enough to melt then record how soft it was after 10 minutes.
lRepeat the process with a piece of chocolate on a plate that you put outside in the sun. Record your results in the same way.
lFind more interesting locations to test how long it takes for the chocolate pieces to melt. You could try your school bag, hot water or even your own mouth.
lCompare your results, in what conditions did the chocolate melt? You might also like to record the temperatures of the locations you used using a thermometer so you can think about what temperature chocolate melts at. At a certain temperature your chocolate pieces undergo a physical change, from a solid to a liquid (or somewhere in between). On a hot day, sunlight is usually enough to melt chocolate, something you might have unfortunately already experienced. You can also reverse the process by putting the melted chocolate into a fridge or freezer where it will go from a liquid back to a solid
