Let's go through each question one by one and solve them with explanations:

1. The smallest unit of matter is:

Answer: C) atom

Explanation:
An atom is the smallest unit of matter that retains the chemical properties of an element. It consists of a nucleus (protons and neutrons) surrounded by electrons. While molecules are made of atoms, and mass and gram are measurements, the atom is the fundamental building block of matter.

> ✔ Correct answer: C) atom

2. When you bake cookies, what kind of reaction is occurring?

Answer: B) chemical reaction

Explanation:
Baking cookies involves heat causing changes in the ingredients — such as proteins denaturing, sugars caramelizing, and starches gelatinizing. These changes result in new substances being formed, which means it's a chemical reaction, not just a physical change.

> ✔ Correct answer: B) chemical reaction

3. Anything that has mass and takes up space is called

Answer: C) matter

Explanation:
The definition of matter is anything that has mass and occupies space. This includes solids, liquids, gases, and plasmas.

- Density = mass/volume
- Volume = amount of space something takes up
- Atoms are parts of matter

So, matter is the correct term.

> ✔ Correct answer: C) matter

4. How much "stuff" is in something is called its:

Answer: C) mass

Explanation:
"Stuff" refers to the amount of material present. Mass measures how much matter is in an object, regardless of gravity.
- Volume is the amount of space it takes up.
- Atoms are particles.
- Matter is the general term for substance.

So, mass is the best answer.

> ✔ Correct answer: C) mass

5. Which is not a state of matter?

Answer: D) helium

Explanation:
The three main states of matter are:
- Solid
- Liquid
- Gas

Helium is a gas at room temperature, but it is an element, not a state of matter. So, while helium *can be* in a gaseous state, “helium” itself is not a state.

> ✔ Correct answer: D) helium

6. Which property of matter tells what something feels like?

Answer: A) shape

Wait! Let’s think carefully.

Actually, shape is not directly about how something *feels*. That would depend on texture, hardness, temperature, etc.

But among the choices:
- Shape: describes form (e.g., round, square), not necessarily how it feels.
- Color: visual property.
- Texture or hardness would better describe "how it feels", but those aren't options.

However, if we consider shape as part of tactile sensation (like feeling a sharp edge vs. smooth curve), it might be relevant.

But none of the options perfectly fit "what something feels like." However, if we must choose from these, shape could influence feel, but none are ideal.

But let's re-evaluate: perhaps the intended answer is A) shape, assuming they mean "physical characteristics that affect touch."

Alternatively, maybe there's a typo or missing option. But based on standard science curriculum:

👉 The best possible choice here is A) shape, though it's not perfect.

But wait — actually, texture or hardness would be better. Since those aren't listed, and color is visual, shape is likely the intended answer because it contributes to how something feels when touched.

Still, this is ambiguous.

But let's suppose the test expects shape as the answer.

> ✔ Most likely expected answer: A) shape

(Though note: This is a weak question. Better answers would include "texture" or "density.")
