NOTES: MATTERScience ch. 3

LOL After taking notes, I will be able to identify and analyze the essential properties of matter.

Key Vocabulary: 1. Matter: solid, liquid, gas, plasma

2. Volume3. Particles4. Mass5. Weight

What is matter? Matter is anything that has mass (volume) and takes up space.

All matter takes up space.

How can matter be described?

1. Matter can be described as an object’s volume, mass, and weight.

2. Matter has 4 states.

What are the 4 states of matter?

The 4 states of matter are:

1. solids 2. Liquids3. Gases4. plasma

What makes up matter?

Matter is made up of particles: atoms and molecules.

Particles are always moving

How do particles move?

Particles move in a random motion.

Particles can move in any direction and at different speeds.

NOTES: MATTER AND VOLUME

L.O. I will be able to measure the volume of regularly shaped objects.

What is volume? 1. Volume is the amount of space an object takes up.

2. Things that have volume cannot take up the same space at the same time.

How do we measure liquid volume?

Measure liquid volume in liters (L).

The liter is the SI unit for volume

How do you measure a liquid correctly?

Measure the volume of a liquid at the meniscus.

What is a meniscus?

The surface of any liquid is curved.

The meniscus is the curve at the surface of a liquid.

How is volume measured using the meniscus?

Measure volume at the lowest point of meniscus at eye level.

How do you measure the volume of a solid object?

Measure volume of a solid object use cubic units.

Cubic = 3 dimensional or 3D

How do you measure the volume of a cube?

Volume of a rectangular solid (formula)

V = volumel = lengthw = widthh = height

V = (L)(w)(h)

How do you find the volume of an irregular solid?

To find the volume of an irregular solid measure the amount of water it displaces.

Formula:V2 – v1 = Volume of

irregular solid object

V2=5.5l V1=4.75 5.5-4.75=1.25 volume of dinosaur

NOTES: MATTER AND MASS

L.O. To identify the difference between mass and weight

What is mass? Mass is the measure of the amount of matter in an object.

Mass = amount of matter in an object.

What are the characteristics of mass?

Characteristics of mass:

1. Mass of an object is constant no matter the location. Mass = size

2. Mass changes only when the amount of matter changes.

3. Mass is expressed in grams (g), kilograms (kg) and milligrams (mg)

4. Mass is measured using a balance scale.

What is weight? Weight is the measure of the gravitational force on an object.

Weight = force

What are the characteristics of weight?

Characteristics of weight:

1.Weight is measured by using a spring scale

2. Weight is expressed in newtons (N).

3. Weight is not constant but varies depending on where the object is in relation to Earth.
