The task involves filling in the blanks related to the
Law of Conservation of Mass. Let's solve it step by step and explain the solution.

The Law of Conservation of Mass
The Law of Conservation of Mass states that
mass cannot be created or destroyed in a chemical reaction. This means that the total mass of the reactants (starting materials) must equal the total mass of the products (resulting materials).

Filling in the Blanks
Here is the text with the blanks:
> The law of conservation of mass says…
>
> - You cannot _______ matter.
> - You cannot _______ matter.
> - You can _______ matter into a new form.
> - The new form will have the _______ amount of mass as the old form.
#### 1.
You cannot _______ matter.
- According to the Law of Conservation of Mass, matter cannot be created out of nothing. Therefore, the first blank should be filled with
"create."
#### 2.
You cannot _______ matter.
- Similarly, matter cannot disappear or be destroyed. Therefore, the second blank should be filled with
"destroy."
#### 3.
You can _______ matter into a new form.
- Matter can change its form through chemical reactions or physical processes (e.g., melting, freezing, burning). Therefore, the third blank should be filled with
"change."
#### 4.
The new form will have the _______ amount of mass as the old form.
- Since mass is conserved, the total mass before and after the change remains the same. Therefore, the fourth blank should be filled with
"same."

Completed Text
After filling in the blanks, the text reads:
> The law of conservation of mass says…
>
> - You cannot
create matter.
> - You cannot
destroy matter.
> - You can
change matter into a new form.
> - The new form will have the
same amount of mass as the old form.

Explanation Using the Image
The image shows two scenarios:
1. A sealed container with a total mass of
98 grams.
2. After some process (e.g., a chemical reaction), the contents are separated, but the total mass of all parts still adds up to
98 grams.
This demonstrates that even though the matter has changed form, the total mass remains constant, reinforcing the Law of Conservation of Mass.

Final Answer
$$
\boxed{\text{create, destroy, change, same}}
$$
