1.
Wood is matter.
Correct Answer
A. True
Explanation
Wood is considered matter because it has mass and occupies space. Matter is anything that has mass and takes up space, and wood meets both of these criteria. Wood is made up of various elements and compounds, such as cellulose and lignin, which are arranged in a specific structure. It can be physically and chemically changed, indicating its matter properties. Therefore, the statement "Wood is matter" is true.
2.
Air is not matter.
Correct Answer
B. False
Explanation
Air is made of gases and water vapor.
3.
Sound is matter.
Correct Answer
B. False
Explanation
Sound is a vibration that typically propagates as an audible wave of pressure, through a transmission medium such as a gas, liquid or solid.
4.
Light is not matter.
Correct Answer
A. True
Explanation
Light is electromagnetic radiation within a certain portion of the electromagnetic spectrum. In other words, it's energy, not matter.
5.
Rocks are matter.
Correct Answer
A. True
Explanation
The statement "Rocks are matter" is true because rocks are composed of solid material and have mass and volume, which are characteristics of matter. Matter refers to anything that occupies space and has mass, and rocks fulfill these criteria. Therefore, rocks can be classified as matter.

[Blank 1] is everywhere around us. On Earth, we find matter in the [Blank 2], water, living things and rocks.
Matter is anything that has [blank 3] and volume.
Mass is the [blank 4] of matter within an object. The measure units are [blank 5] (kg) or [blank 6] (g). We measure mass with a [blank 7].
Volume is the [blank 8] that a substance takes up. The measure units are [blank 9] (l) or [blank 10] (ml). We measure volume with a [blank 11] tube.
Correct Answer
matter
air
mass
amount
kilograms
grams
scale
space
litres
millilitres
measuring
Explanation
Matter refers to anything that has mass and takes up space. In the given context, matter is described as being everywhere around us, including in the air, water, living things, and rocks. Mass is the amount of matter within an object, and it is measured in kilograms or grams using a scale. Volume is the space that a substance takes up, and it is measured in liters or milliliters using a measuring tube.
7.
What are we measuring in the picture?
Correct Answer
A. Volume
Explanation
In the given picture, we are measuring the volume. Volume refers to the amount of space occupied by an object or substance. It is typically measured in cubic units.
8.
What are we measuring in the picture?
Correct Answer
A. Mass
Explanation
The correct answer is Mass. In the picture, we are measuring the mass of an object. Mass is a measure of the amount of matter in an object and is often measured using a scale or balance. It is different from weight, which is the force exerted on an object due to gravity.
9.
Select the correct measure units of volume:
Correct Answer(s)
A. Litres
C. Millilitres
Explanation
The correct measure units of volume are litres and millilitres. Litres are commonly used to measure larger volumes, while millilitres are used for smaller volumes. Kilograms and centilitres are not units of volume, but rather units of weight and smaller units of capacity, respectively.
10.
Select the correct measure units of mass:
Correct Answer(s)
A. Kilograms
B. Grams
Explanation
The correct answer is kilograms and grams. Kilograms and grams are both commonly used units of mass. Kilograms are used for measuring larger masses, while grams are used for smaller masses. Litres and millilitres, on the other hand, are units of volume and not mass. Therefore, they are not the correct measure units of mass.
11.
We can measure the volume of an object by putting it into a measuring tube and subtracting the resulting volume from the first one.
Correct Answer
A. True
Explanation
This statement is true because when we put an object into a measuring tube, the volume of the object displaces the liquid in the tube. By subtracting the initial volume of the liquid in the tube from the final volume after adding the object, we can determine the volume of the object.
12.
How can we measure the mass of an object?
Correct Answer
A. By putting it on a scale and seeing the grams it has.
Explanation
The mass of an object can be measured by putting it on a scale and seeing the grams it has. This is because scales are designed to measure the force exerted by an object due to gravity, which is directly proportional to its mass. The reading on the scale indicates the weight of the object, which can be converted to grams using appropriate units.
