Science: Third Grade
This course offers an in depth study of four main areas scientific areas. These areas include rocks
and minerals, chemical tests, plant growth and development with a special focus on designing hand
pollinators. Throughout the year, the students will have opportunities to investigate scientific
questions using inquiry based strategies. This includes, but not limited to, the use of texts, hands on
experiments, and the use of multimedia.

3.1.3. C3. CONSTANCY AND CHANGE Recognize that fossils provide us with information
about living things that inhabited the Earth long ago
Standards: 3.2.3. B4. Identify and classify objects and materials as magnetic or nonmagnetic
3.3.3. A2. Identify the physical properties of minerals and demonstrate how minerals can be
tested for these different physical properties
Field Tests- tests we performed on our minerals; Geologist- a person who studies rocks and
minerals; Igneous- rock produced under conditions involving intense heat, as rocks of
volcanic origin or rocks crystallized from molten magma; Luster- another word for shine;
Metamorphic- rock that was once one form of rock but changed to another under the
influence of heat, pressure or some other agent without passing through a liquid phase;
Vocabulary: Observable Color- the color you see with your eyes; Opaque- when you cannot see any light
through it; Penlight – a tool we used for the light and luster test; Rock Cycle- the process,
by which rocks are formed, altered, destroyed, and reformed by geological processes and which
is recurrent, returning to a starting point; Sedimentary- rock that has formed through the
deposition and solidification of sediment; Translucent- the object looks cloudy when light
shines through it; Transparent- light shines clearly through the object

Observe and record the changes that occur during the heating and cooling process
Observe and record changes in the properties of matter
Investigate the temperature changes that result from the addition. or removal of heat
Describe, identify and classify objects based on their properties
Make observations based on the changes that occur as a result of the addition or removal
of heat.
Interpret the changes that take place due to basic reactions.
Record the observable changes that take place.
Analyze and record the temperature change that occurs during hearing and cooling.
Given an object, students will identify its properties.
Resources: Chemical Tests
3.2.3. A1. Differentiate between properties of objects such as size, shape, and weight and
properties of materials that make up the objects such as color, texture, and hardness.
Differentiate between the three states of matter, classifying a substance as a solid, liquid, or gas
3.2.3. A3. Demonstrate how heating and cooling may cause changes in the properties of
Standards: materials including phase changes
3.2.3. A4. Use basic reactions to demonstrate observable changes in properties of matter (e.g.,
burning, cooking)
3.2.3. B3. Explore temperature changes that result from the addition or removal of heat
Acid- a type of chemical that is usually sour, reacts with many metals, can be poisonous and
can burn (examples: lemon juice and vinegar); Base- is a type of chemical that tastes bitter,
feels slippery, and is found in household cleaners, detergents, cements, and medicines;
Chemical Property- a substance is its ability to change into a new material; Controlunchanged part of an experiment used to compare the changed part with it; Crystal – is a solid
substance with a regular geometric pattern; Dissolved- it is spread evenly throughout another
Vocabulary: substance and is not visible; Evaporation- is the process by which a liquid changes into a gas;
Filtration- the process of passing a liquid through a substance with small holes in it, in order
to separate any solids from that liquid; Mixture- a combination of two or more different
substances that keep their own properties and can readily be separated; Neutral- type of
chemical that is neither acid nor base (example: water); Physical Properties- properties that
can be observed without changing the chemical makeup of the material (such as shape, color,

size and texture); Property- an object describes how it looks, feels, smells, or sounds; Salt- is
an example of a crystal with a cubic geometric pattern; Solution- a kind of mixture that is
evenly mixed, you cannot see the parts that make it up, and it is usually clear; Suspension- an
unevenly mixed kind of mixture in which the parts can be easily seen and it is cloudy

Use a specific set of steps (process) consistently to recognize what plants and animals
need to grow
Observe plant growth over an extended period of time
Compare and contrast the growth of a plant exposed to light vs. a plant that is not
exposed to light
Prove the cause and effect relationship of plant survival through adaption
Distinguish the relationship between plant and animal characteristics from parent to
offspring
Generate and compare/contrast models and diagrams of various animal and plant life
cycles
Recognize the structures on plants that are responsible for food production, support,
water transport, reproduction, growth, and production
Describe, identify, and classify differences in life cycles
Describe, identify, and classify predictable life cycles
Describe, identify, and classify the basic needs of living things
Describe, identify, and classify living things
Construct a set of steps previously used to investigate what animals and plants need to
grow.
Make observations based on the growth of a plant over an extended period of time.
Give an example of an adaptation and the causal relationship between the adaptation and
the need of that adaptation (Ex. Root growth in water scarce areas).
Construct a graphic organizer that formulates the outcome of characteristics from parent to
offspring.
Design and refine a model that represents the various animal and plant life cycles.
Identify the structures through the use of labeling and accurately connecting the
appropriate part with its function.
Given a graphic organizer (Venn diagram, etc.) students will be able to identify the life
cycles of plants and animals.
Given the steps, students will be able to identify, and classify predictable life cycles that
include birth, growth, development, reproduction, and death.
Given a living thing, students are able identify and classify the basic needs of living things.
Given a living thing students are able to accurately identify and classify it.
