Arajena™ Learning / Semester 1
Designed by a Registered Nurse and Homeschool Mom
Bring human biology to life with Arajena™ Learning Semester 1, a complete, open-and-go homeschool science bundle featuring five hands-on investigations comprising 30 engaging lessons, prepared lab materials, and guided digital learning. Designed to make discovering the human body exciting, interactive, and unforgettable, Arajena transforms science education into an immersive, hands-on learning adventure.
What makes Arajena different?
Four complete components work together so you can open the box and start learning.
A full-color, illustrated curriculum guide with five structured anatomy investigations, labeling exercises, and reinforcement worksheets.
Every supply for the five core investigations is prepared and included — from the wearable brain hat and modeling compound to the stethoscope build kit.
A comprehensive planner with step-by-step lesson layouts, educator guidance, answer keys, and review activities — no lesson planning required.
Prerecorded video lessons, interactive anatomy games, and 3D organ models reinforce every investigation for self-paced learning.
Each investigation builds on the last, guiding students through the body's most amazing systems.
Investigation 1
Discover the body's remarkable command center! Explore the major lobes of the brain, the left and right hemispheres, the corpus callosum, and how different brain regions contribute to memory, movement, sensation, and communication.
A wearable brain anatomy hat, anatomical labeling exercises, and building colorful brain models using modeling compound.
Investigation 2
How does your brain communicate with your toes? Investigate neurons, nerve impulses, myelin, and the fascinating communication network connecting the brain, spinal cord, and body.
Students construct educational neuron models, explore a hands-on nerve signal demonstration, and reinforce scientific vocabulary using reusable anatomical learning materials.
Investigation 3
Did you know your brain produces electrical activity even while you sleep? Discover EEG (electroencephalography), neurofeedback concepts, and the fascinating patterns of delta, theta, alpha, and beta brainwaves.
Students create colorful brainwave models, investigate EEG electrode placement, explore brainwave patterns, and learn how brain activity can be observed through specialized technology.
Investigation 4
What keeps your blood moving every minute of the day? Explore heart anatomy, chambers, valves, blood circulation, and the cardiovascular system.
Students build an educational stethoscope model, investigate the path of blood through the heart, construct anatomical models, and complete interactive heart-labeling activities.
Investigation 5
Take a deep breath and discover the science behind breathing! Explore the respiratory system, trachea, bronchi, lungs, inhalation, exhalation, and gas exchange.
Students construct an interactive lung demonstration model, identify respiratory structures, explore breathing mechanics, and reinforce their understanding through hands-on anatomical investigations.
Arajena™ Learning brings anatomy and physiology to life through exciting, hands-on discoveries! Designed for elementary-aged learners, our curriculum combines engaging lessons, interactive activities, 3D models, educational games, and creative investigations to make complex science concepts fun and easy to understand.
Younger learners benefit from guided, hands-on exploration, while older students dive deeper into scientific vocabulary and how the human body works. With easy-to-follow parent scripts and all essential supplies included, learning science at home has never been easier!
Think Explore Create Discover
How It Works
Your bundle includes the curriculum, parent planner, and every physical supply for the core investigations.
Use the illustrated curriculum, parent planner, and Nurse Rachel’s videos to guide each investigation.
Explore anatomy together through hands-on activities, curiosity-driven discovery, and memorable learning experiences.
Discover what homeschool families loved about Nurse Rachel's interactive anatomy and physiology classes. Her uniquely memorable teaching style has inspired deep curiosity and helped children understand exactly how the human body works.
“They even were able to answer some Jeopardy questions thanks to her class. My boys are only 8 & 9 years old.”

Homeschool Parent
“She has such a gift for taking what could easily be a complicated subject and making it fun, engaging, and memorable for the kids.”
Stephanie V.
Homeschool Parent
“Each class he would come home with a project based on the class, and he would come home and completely explain how it worked”
