From our teachers' playbook

Plants, animals and the amazing human body!

What do kids learn in life science?

Life science is the study of living things. Kids learn what plants need to grow, name the parts of a plant and a flower, and watch life cycles like a caterpillar becoming a butterfly. They group animals into mammals, birds, reptiles, fish and more, and learn how adaptations help animals survive. They also explore their own bodies: bones, muscles, skin and the five senses. As they grow, kids look closer at cells, the tiny building blocks of every living thing. The click moment is when kids see how every living thing fits its environment.

Our favorite ways to teach life science

Life science comes alive when kids can observe, sort and draw. These moves make it hands-on.

Label a real flower

Bring in a real flower and have kids gently pull it apart to find the petals, stem and roots. Then they label a diagram. Matching the real thing to a picture builds strong vocabulary.

Why it works: children learn more from words and pictures together than from words alone (Mayer, 2009).

Animal word match

Quick matching rounds of animal words and pictures keep new vocabulary fresh. Repeat a few times a week as a warm-up.

Why it works: researchers who compared ten study methods found practice testing is one of the two that work best (Dunlosky and colleagues, 2013).

Questions parents and teachers ask us

What is life science for kids?

Life science is the study of living things, including plants, animals and people. Kids learn about life cycles, habitats, body systems and what living things need to survive.

What topics are in elementary life science?

Common topics include plant parts and needs, animal groups, life cycles, habitats and adaptations, the human body and the five senses. Older grades add cells and ecosystems.

How can I teach life science at home?

Plant seeds, watch birds, visit a park or zoo, and talk about how animals live. Simple observations and questions build real science skills.

What is the difference between life science and physical science?

Life science studies living things like plants and animals. Physical science studies matter, energy, forces and motion.
