• Introduction to biology, chemistry, earth & space, and physics
• Full-colored student workbook
• Student assessments
• Supplies and equipment needed for experiments
• Real-world application

No prior teaching or science experience is needed! Teachers and parents, you will be well-equipped. Science Unlocked detailed teacher guides will help guide you through assisting with hands-on science curriculum learning experiences with:

• Context and answers to student questions
• Options for including children of different ages and abilities
• Step-by-step experiment instructions
• Lesson planning timeline

The Wonder Year 2 (Grades K-2) Science Unlocked homeschool elementary science curriculum bundle includes the following kits:

Unit 1: Physical Science (3 Kits)

Brick by Brick

Properties and Purposes of Building Materials

Learn how small things stick together to make big things, make rocks bubble, and design a tiny house to explore chemistry.

A-Maze-ing Mirrors

An Introduction to Light

Investigate the world of light and discover what happens when it hits different objects with a periscope, mirror maze, and more.

That's a Sound Idea

Sound, Vibration, and Communication

Make some noise! You’ll be cheering with delight when you do these hands-on experiments about sound and vibration.

Unit 2: Earth and Space Science (2 Kits)

Go with the Flow

How Dams Impact the Environment

Build and test dams and a watershed to learn how animals and people impact the environment by changing the flow of water.

Not-So-Solid Ground

Fast and Slow Changes on Earth’s Surface

Learn how Earth’s surface features are changed by natural and human-caused events with sand castles and landform models.

Unit 3: Life Science (1 Kit)

Keys to Life

Food, Water, Shelter, and Space

What are the four keys to life for plants and animals? Sprout seeds, dissect an owl pellet, and build animal homes to find out!

More information about the learning objectives in each kit can be found in the contents section below. This NAPPA award-winning curriculum is based on NGSS science standards for kindergarten through 2nd grade science education. Read below in the contents section to learn more about the standards met in each kit. Find out why Science Unlocked is considered the best elementary homeschool science curriculum.
