The statement presented in the question is false. You can take an object, break it into small pieces, and then put it back together to create something new. If you were to build a castle with blocks, you could knock it down and build something else instead. This is a simple example of making something new out of the pieces of something else.

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.

Let's take a look at the tools given in the answer choices:
A thermometer is used to measure the temperature of something, or to determine how hot or cold something is.
A scale is used to determine the weight of an object.
A measuring cup is used to determine the amount of something. Measuring cups are often used in baking. For example, if a recipe called for two cups of sugar, you would use a measuring cup to measure out two cups of sugar.
A ruler is used to measure the length of something.
Based on the question, we are trying to determine how hot the hot chocolate is, so we would use a thermometer.

An observable property is something that describes an item or material and is gathered using the five senses. A dirty sock is an irregular shape, soft, white, and smelly. Someone could touch, smell, and see a dirty sock and find all of these properties are true.

The item that is most likely describing the seashell is "Item 1". A seashell has all of the matching observable properties, so it could be classified in the same category. A seashell is hard, does not bounce, is irregularly shaped, tan, and would feel rough to the touch. None of the other items would be a match.

"Item 2" is described as hard, not bouncy, square, green, and smooth to the touch. When reviewing the answer choices, they are all green but have other observable properties that would not allow them to be classified as "Item 2". The tennis ball is round, the block is rough on top and rectangular, and the leaves are irregular shaped. The only answer choice that matches the characteristics is the cube.

When looking at items or materials, we can classify them based on their observable properties. If we look at the different descriptions of all four items and then think about a tennis ball, some similarities can be found between item 4 and a tennis ball. They can be described with the same properties, so they fall into the same category.
