Let’s go through each question one by one, carefully and clearly.

Question 1: When measuring liquid use
Liquids are measured by volume. Common units for liquid volume include milliliters (mL) and liters (L).
- mL is a standard unit for small amounts of liquid (like medicine or water in a cup).
- cm³ (cubic centimeters) is also equal to 1 mL — so it *can* be used, but it’s more common in science for solids or precise lab work.
- Inches and centimeters measure length, not volume → wrong.
But the question says “use” — meaning what do we typically use? In everyday life, especially in cooking or drinking, we say “mL” or “liters”. Between A and C, both are technically correct, but
A (mL) is the most direct and commonly taught answer for liquids at this level.
✔ Best answer:
A

Question 2: Meters, millimeters and centimeters are all ways to measure
These are all metric units for distance or size from end to end → that’s
length.
- Weight is measured in grams/kilograms.
- Volume is in liters/mL.
- Density is mass/volume → not these.
✔ Answer:
A

Question 3: Speed is measured in
Speed = distance over time. So any unit that shows how far something goes in a certain time works.
- meters per second → yes (scientific)
- miles per hour → yes (common in US)
- kilometers per hour → yes (common worldwide)
→ So “all answers are correct” is true!
✔ Answer:
C

Question 4: Grams is a unit of measurement for
Grams measure how much stuff is in an object → that’s
mass.
- Not density (that’s g/cm³)
- Not height (that’s cm/m)
- Mass ≠ weight (weight depends on gravity)
✔ Answer:
A
---
Question 5: Mass and weight are the same exact thing.
NO! This is a common mistake.
-
Mass = amount of matter (doesn’t change if you go to space)
-
Weight = force of gravity pulling on that mass (changes if you’re on Moon vs Earth)
So they are NOT the same. The option says “Falsey falsey false false” — which is just a funny way of saying FALSE. And “True!” is obviously wrong.
✔ Answer:
A

Question 6: Inches, feet, yards, meters and miles all measure
All of these are units of
length/distance.
- Mass? No → that’s grams/pounds
- Volume? No → that’s cups/liters
- Seth’s boogers? 😂 Funny, but no.
- Length? YES.
✔ Answer:
D

Question 7: The amount of matter in an object is
That’s the definition of
mass.
- Weight is how heavy it feels due to gravity.
Example: Your mass is the same on Earth and Moon, but your weight is less on Moon.
