Valentines Day Science Lab: Melting point of chocolates

I can across this on the Hershey website and thought it would be a fun activity for my class.

Materials:
- Milk chocolate chips
- White chocolate chips
- Dark chocolate chips
- Hot plate
- Bowls
- Stop watch

Objective: To see which type of chocolate will melt the fastest.

Have students make a prediction. You could make a graph as well.

Break class into groups.

Give each group one of each type of chocolate.

Have the groups put the chocolate in a bowl one at a time on the hot plate and time how long it takes to melt.

Have them record their observations.
