Free Endocrine System Labeling Worksheet For Kids
The endocrine system labeling worksheet is a hands-on way to introduce kids to one of the bodyโs most important communication networks.
When my son worked on this, the act of placing each label helped him understand that glands arenโt just vocabulary words, they connect to real functions like growth, energy, and mood.
Whether youโre homeschooling or in the classroom, these free science worksheets provide a clear visual guide and come with an answer sheet to make checking quick and easy.

How to Use the Endocrine System Labeling Worksheet
This free worksheet gives students a clear diagram of the endocrine system with space to label each gland.
A word bank is included to support younger learners, along with a separate answer sheet for easy checking.
Iโve found it works best as a quick review after introducing the topic in class or at home. Kids get immediate practice connecting new terms to a visual.
You can also assign it as homework, use it in small groups, or add it to a human body systems unit for reinforcement.
What is the Endocrine System?
The endocrine system is a group of glands that release hormones, chemical messengers that keep your body in balance. These hormones affect everything from how you sleep and grow to how your body handles stress and energy.
Pineal gland
Deep in the brain, the pineal gland acts like a clock, producing melatonin to help you fall asleep and wake up at the right times.
Hypothalamus
The hypothalamus connects your brain to your hormone system, controlling hunger, body temperature, and more. It also tells the pituitary gland when to get to work.
Pituitary gland
Often called the โmaster gland,โ the pituitary sends out signals that control growth, reproduction, and many other essential functions.
Thyroid gland
Shaped like a butterfly in your neck, the thyroid regulates metabolismโhow your body uses energy. It affects your heartbeat, temperature, and overall energy levels.
Thymus
Most active during childhood, the thymus helps train your immune system to recognize and fight germs.
Pancreas
Located behind the stomach, the pancreas controls blood sugar by releasing insulin and glucagon, and it also makes digestive enzymes.
Adrenal glands
Sitting on top of your kidneys, the adrenal glands release adrenaline and cortisol, giving your body a boost during stress.
Ovary (Females)
The ovaries produce estrogen and progesterone, guiding puberty and pregnancy while also releasing eggs.
Placenta (Females, during pregnancy only)
The placenta forms during pregnancy, delivering nutrients and oxygen to the baby and producing hormones to support healthy development.
Testicle (Male)
The testicles make testosterone, which supports male development, and they are also where sperm is produced.
More Body Systems Worksheets
If your kids enjoyed labeling the endocrine system, you might want to keep the momentum going with other body system activities. These are some of the ones weโve used alongside anatomy lessons:
- Body System Word Search โ A fun way to reinforce vocabulary. My son liked using this as a warm-up activity before diving into labeling worksheets.
- Lymphatic System Labeling Worksheet โ A good follow-up once students are comfortable with the endocrine glands. It shows how another system works to protect the body.
- Human Body Organs Worksheet โ Helps students see the bigger picture by connecting individual glands and organs into one complete system. Great for review or end-of-unit practice.
Best Human Body Books for Kids
I like to pair worksheets with books so kids get both visuals and context. These are a few that worked well for us:
- Endocrinology for Kids โ A bright picture book that makes hormones simple enough for elementary learners.
- Know Yourself โ An interactive series with stories and activities. My son enjoyed how engaging it was. (Youโll also get 15% off with my link.)
- Human Body Learning Lab โ Hands-on projects that help kids connect what theyโre reading to real life.
- Human Anatomy for Kids โ A clear overview of different body systems, easy for kids to follow independently.
- Human Body! โ Beautiful illustrations and broad coverage, perfect to keep on hand for reference.
