Different Types of Chocolate Melting

Science experiment to see what kind of chocolate melts the fastest.

This science project was done by Janice and Marta, who are students at Texas School for the Blind and Visually Impaired (TSBVI).


Which Hershey’s chocolate will melt the fastest:  milk, dark, or cookies and cream?


The dark chocolate will melt fastest.



Purchase chocolates and find a lamp.

Which chocolate will melt fastest?

  1. We will put 3 pieces of chocolate candy on a white paper towel.
  2. We will put chocolate pieces about 5 centimeters away from a 60 watt bulb.
  3. We will test the chocolate every 15 sec by touching it with a finger to see if it melted.
  4. We will make a tally how many seconds it will take for each one to melt.  We also make notes on how it looks as it melts.
  5. We will eat the melted chocolate!reese cup

Data and Results

Time to melt:

Our hypothesis was not correct because the milk chocolate melted faster.


Several other variable can be tested and were considered.  These include brand of chocolate and various specialty chocolates. We didn’t test these variables for this experiment, though.
