Who says you are too young to learn about science? This experiment is focused at young children, even toddlers can learn something from this one, and have fun doing it too! It’s a super simple experiment and can be done using all sorts of bits and bobs that you have lying around the house or classroom. All you need is a hot summers day and some time to spare!

What Melts In The Sun?  

This experiment is used to showcase the fact that firstly, heat causes things to melt and secondly, that all things have different melting points. 

To Run The Experiment, You Will Need The following:  

• Some fresh and eager young minds 
• A hot summer’s day 
• Time 
• A muffin pan 
• Food stuffs and items that you have found around the house/classroom 

FOR EXAMPLE, YOU COULD USE A VARIETY OF THE FOLLOWING:

• A coin 
• An ice-block 
• Crayons 
• A piece of Lego 
• A blob of butter 
• A piece of cheese 
• A wooden block 
• A marble 
• A piece of chocolate/marshmallow 
• Some jelly 

This is just a suggested list, get the kids to help you choose the items, but make sure that some can melt from the heat of the sun alone.

Instructions:  

After you have selected your 12 various items/food stuffs, get the kids to place each one into each of the separate muffin holders in their tin/pan. If you are doing the experiment with older children, then let them write down the items in a list and allow them an opportunity to guess if each item will melt in the sun or not, they can even try and guess which item will melt first, second, third etc. Then it’s time to place your pan and its goodies into the direct sunlight, preferably outdoors. You have two choices here, you can either leave the pan and come back in a few minutes/hours (depending on how hot the day is) or you can hang around with the kids to witness which of the objects start to melt first, second, third etc.

The Explanation  

All objects have a melting point, some can melt by the heat of the sun while others need more extreme temperatures to melt. Water is known to reach melting point at zero degrees Celsius (32 degrees Fahrenheit). Objects that hold more water will melt faster e.g. an ice cube or blob of butter. The solid coin on the other hand needs a more extreme temperature to reach melting point, same goes for the marble and Lego etc.  

The lesson: heat makes things melt, different objects melt at different temperatures, the more water an object holds, the faster it melts. 

Did you know: The melting point of a primarily copper coin is 1082.778 degrees Celsius (1981 degrees Fahrenheit).

Cleaning up! End this experiment in an even more super fun way by allowing the kids to scoop up and eat the melted treats i.e. Marshmallows, chocolate, fudge, toffees. This can be a fun experiment from start to finish and can pass a good  couple of hours of the day. Enjoy it with little ones young and old!
