1. Life

●Animals

The unit Animals helps students discover what makes animals

similar and what makes them different. Understanding the diversity

among animals helps students appreciate and enjoy the uniqueness of

all creatures. Topics include habitat, diet, body parts, movement,

special abilities, and more.

Students need to think about how they treat animals and how are

they fit into the animal kingdom.

●Living/Non-Living

This unit helps students explore the important differences between

the two. It also addresses topics such as: Non-living components of

living things, nurse logs, sea stars, babies and parents, and cells.

●Plants

This unit helps students explore what plants require for survival,

how plants grow, plant parts and their functions, how people and

other animals use plants, special types of plants, where different

kinds of plants can be found, and other plant-related topics.

Students may gain an appreciation for the amazing diversity of plant life on Earth and the extensive roles that plants play in their

lives.

●Senses

This unit helps students explore how and why humans use their five

senses. It addresses the body parts used for each sense, as well as

how these senses communicate with the brain to make meaning of

the incoming information. The unit also addresses how each sense

keeps us safe.

It is important for students to appreciate and protect their senses

so they can learn from the world around them and have a lifetime full

of rich experiences.

2. Earth & Space

●Earth, Moon, and Sun

This unit helps students understand that Earth rotates on its axis,

Earth revolves around the Sun, and the Moon revolves around

Earth. Humans have an ever-growing understanding of how the

Earth, Moon, and Sun move and interact. This understanding

helpsstudents make sense of what they see in the sky, both by day

and by night.

An understanding of our nearby space neighborhood can also

inspire future exploration deeper into space, which may someday

even include the discovery of life on distant planets.

●Weather

This unit helps students explore weather's many different aspects,

including temperature, wind, clouds, precipitation, and storms.

Certain unit materials address what causes the weather to occur. The

unit also draws connections between the seasons and their weather

patterns.

This unit provides opportunities for students to learn more about

natural weather phenomena they observe in their everyday lives.

Understanding the weather can also prepare us to take precautions

that will keep us safe in the event of severe weather.

●Earth’s surface

This unit helps students explore the land and water that make up

Earth's surface. Earth's surface is shaped into various landforms by

gravity, wind, water, and the movements of Earth's crust. Earth's

surface provides everything needed for life to thrive, including shelter,

food, and water.

Understanding Earth’s surface will help students appreciate the

uniqueness of our planet and may encourage them to take action to

protect it.

3. Physical

●Doing work

This unit helps students explore the concepts of work and force.

Students will learn that the amount of work required to perform a task

depends on the amount of force needed to move it, as well as the

distance an object will be moved.

●Energy

This unit helps students understand what energy is. Unit materials

focus primarily on five important types of energy: light, sound, motion,

heat, and electrical. Each energy type is defined and supported with

everyday examples.

It’s important to understand where energy comes from, how it

behaves, and why it is valuable to us. By becoming familiar with

different types of energy, students can better appreciate having the

energy sources they rely upon in daily lives.

●Light

This unit helps students explore the properties of light: where it

comes from, how it moves,and how it interacts with objects.

Understanding the physical properties of light helps us anticipate

how light will behave as we use it and interact with it. Light also adds

to the beauty and complexity of the world around us.

●Properties

This unit explains how shape, color, texture, weight, state of matter,

and other properties can be used to identify, describe, and compare

matter. The unit also explains that we choose to make things out of

materials that have the properties we need or want.

Identifying properties of objects helps us make decisions and

communicate with precision. Practicing careful observation will

prepare students to become successful scientists and citizens. It may

also allow them to appreciate the special qualities of the things

around them that they might normally take for granted.

●Magnets

In this unit, students will learn that magnets behave in predictable ways, making them reliable and valuable tools.

Things move

This unit explains these forces, and it describes the movement of objects, including how forces can move things, stop them, and change their speed and direction. Knowing how and why things move allows us to work, play, get around, and complete everyday tasks.

4. Process

Tools

1. Thermometers

Thermometers are tools used for measuring temperature.

By using the resources below, students will learn about this

important science tool and practice using it in meaningful

ways.

2. Balance Scales

Thermometers are tools used for measuri …… 此处隐藏:6029字,全部文档内容请下载后查看。喜欢就下载吧 ……
