Baking a cake is a change that is caused by heat. The batter is mixed together, and heat is applied to create a chemical change while the food is baking. It cannot be reversed and returned to a mixture or the individual ingredients.

Heating and cooling is a process that can be reversed. I melted a popsicle and then put the popsicle back in the freezer, and it froze into a solid popsicle again. I did this multiple times, and it always worked. This is an argument based on evidence.

Heating and cooling is a process that cannot be reversed. I had a candy bar in my pocket, and it melted. I was so angry that I had wasted it, so I threw it out. This is an argument based on evidence.

The statement above is a true statement and example of how heating and cooling can be reversed. If you melt a crayon, it goes from a solid to a liquid. This can be reversed, and the crayon can be returned to a solid-state by freezing or cooling it. Some changes cannot be reversed, but this example can be reversed.

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?

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.

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?

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.

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.

The statement above is a false statement and an example of how heating and cooling can NOT be reversed. If you bake a cake, a chemical change has occurred when the heat was applied. This cannot be reversed, and the cake cannot be returned to a batter or individual ingredients.

The statement above is a false statement and an example of how heating and cooling can NOT be reversed. Once a match is struck and lit, it cannot be reversed. The match can be put out, but it cannot "unlit" or brought back to its original state.

Today Patrick and Annie's mother made French toast for breakfast. She asks them if the changes to the bread can be reversed or not. Annie says the changes cannot be reversed, and Patrick says the changes can be reversed. Using this example, who is correct, Annie or Patrick, and why?

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.

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.

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.

The photo is an example of a change that CAN be reversed. If the large block of ice starts to melt and the temperature drops again, it will refreeze. If the Sun comes out and it warms up, it will begin to melt again.
