An example of a change caused by heating or cooling that can be reversed would be the melting of a candy bar and then putting it into the refrigerator to reset the chocolate.
An example of a change caused by heating or cooling that can be reversed would be the melting of a candy bar and then putting it into the refrigerator to reset the chocolate.
The statement above is a true statement and example of how heating and cooling can be reversed. If you melt a candy bar, the chocolate goes from a solid to a liquid. This can be reversed, and the candy bar can be returned to a solid-state by freezing or cooling it. Some changes cannot be reversed, but this example can be reversed.

Today is the 4th of July, and Sammie's dad celebrated with fireworks. He lit them in the yard for everyone to see. His dad asks them if the changes made to the fireworks can be reversed or not. Sammie says the changes cannot be reversed, and his dad says the changes can be reversed. How can Sammie's dad prove the changes can be reversed?

If Sammie's father wants to prove that he can reverse the changes to the fireworks, then he would need to return them to their original state. He needs to reverse anything that has been done to them in the process of lighting them or during the explosion.

Becca says that some heating changes can be reversed. She gives the example of melting butter. She says that you can turn a solid piece of butter into a liquid and then turn it back to a solid. Her friend Melva disagrees and says butter cannot be changed back and forth.
Who is correct, and why?

Who is correct, and why?
Butter is an excellent example of a heating change that can be reversed. Becca can melt butter and then cool it to reverse the effects. Melva disagreed with her but is unfortunately wrong in this case. Some heating and cooling changes can be reversed.

Which material can be heated or cooled, and then have the changes reversed?
Which material can be heated or cooled, and then have the changes reversed?
Some objects or materials can be heated or cooled, and the changes caused can be reversed. An ice cube could have the changes applied to it reversed. If you heat an ice cube it will melt, you can refreeze it to turn it back to a solid. If you toast bread, bake a cake, or cook an egg, that change cannot be reversed.

Will says some changes caused by heating cannot be reversed. Angelo says some changes can be reversed.
Their father takes a popsicle out of the freezer and sets it on the counter. The popsicle begins to melt. He gets a call and puts it back into the freezer.
Using this example who is correct, Will or Angelo, and why?

Using this example who is correct, Will or Angelo, and why?
In the situation presented, Angelo is correct. The changes to the popsicle can be reversed. Once it has been heated up and starts to melt, there is a change. In this case, their father puts it back into the freezer when he gets the call; this would cause the popsicle to refreeze. In some instances, these changes can not be reversed, but in this example, it is possible.

Which photo represents a heating or cooling change that can be reversed?
Which photo represents a heating or cooling change that can be reversed?
The photo that represents a heating or cooling change that can be reversed is the candle with melting wax. Once the candle is no longer lit, the wax will reharden and no longer will be a liquid. Baking a cake, heating toast, and lighting fireworks are all examples of applying heat in a way that cannot be reversed.

In the situation presented, Annie is correct. The changes to the bread are not able to be reversed once it has been heated up and turned into French toast. In some instances, these changes can be reversed like an ice cube or chocolate bar. If these items are melted, they can be cooled and will return to a solid. Once the bread is cooked, it cannot be changed back.

Sammie is correct in this situation. Once the fireworks are lit and the explosion happens, there is no way for this change to be reversed. The firework cannot be "unlit" and put back into the container once the heat has been applied. Something like a chocolate bar can have heat applied and then reversed once it is cooled, but fireworks are an example of something that cannot be changed.

The statement in the question is correct. Some changes can be reversed when something is heated or cooled, and others cannot. Boiling water can be reversed, once the steam cools it is liquid water again. Lighting a piece of paper on fire cannot be reversed; the paper cannot be returned to its original state.

The photo that demonstrates a change that cannot be reversed is the pan of brownies. Writing with markers can be erased and reversed, ice cubes can be heated and cooled multiple times between states, and a puzzle can be taken apart and put back together. Once the ingredients are mixed into a batter and then heated, the brownies cannot be turned into mixture again.

Some changes caused by heating or cooling cannot be reversed. This statement is true, so in the cases of Becky and her sister Maddy, Becky is correct. Some changes caused by heating, like cooking a potato, can't be reversed. There is no way to take the potato from cooked and get it back into its raw form.
