- Sometimes these changes are reversible and can be changed back.
- Sometimes these changes are non-reversible and cannot be changed back.

Discussion Questions
- Before VideoWhat causes chocolate to melt?ANSWER
Heat causes chocolate to melt. When something melts it changes from a solid to a liquid.
Ice, ice cream, popsicles, chocolate and crayons all melt when heated up. Even metal can melt when heated, but it has to get extremely hot.
It freezes into ice. Freezing is when something cools down and changes from a liquid to a solid.
A reversible change is a change that can be undone or changed back. Melting and freezing chocolate is an example of a reversible change.
Observable means we can see it with our eyes. Scientists use their senses to make observations and understand the world around us.
- After VideoWhat are some examples of heating?ANSWER
Heating up marshmallows in a fire and heating up clothes with an iron are both examples of heating.
Cooling down a drink with ice and cooling your breath due to the cold air outside are both common examples.
Butter changes from a solid to a liquid when it is heated.
A reversible change means the change can be undone. If the object that changed can go back to its original form, then it is reversible.
Melting butter then cooling it and melting an ice cube then re-freezing it in the freezer are both common examples.
Popcorn popping, cooking eggs, making cupcakes, and lighting something on fire are all common examples. You know it’s non-reversible because it cannot change back to the original form.

Heating raises the temperature of something.
When things heat up, they get warmer. We heat food to make breakfast, lunch and dinner. Heating coffee or tea can make it more enjoyable. People also heat clothes to take out the wrinkles.

A marshmallow can change from a solid to a liquid when it is heated. Sometimes that marshmallow just gets soft and warm and sometimes it can get burned.

In places where it is very cold, a cup of water left outside can turn into ice. Changing from a liquid to a solid is called freezing. You can keep food in a freezer which keeps it very cold.

Common ways to cool things down are to put them in ice or taking them some place where it is cold. This will lower the temperature. On a hot day, a cold cup of lemonade can taste refreshing!

Reversible means that the change caused by heating or cooling can be undone. One example of this is when you melt butter. After melting, you can cool it down and it will become solid again.

Non-reversible means that the change from heating or cooling cannot be undone. One example of this is when you cook an egg. After heating, it cannot go back to the way it was before.
