From our teachers' playbook

Roots, fins, fur and five senses

What do 1st graders learn in life science?

First graders look closely at living things and ask, "How does this help it survive?" They learn that plants have parts with jobs, roots drink · stems hold up · leaves make food, and that animals use body parts like claws, fins and shells to find food and stay safe. They notice that baby animals look a lot like their parents, but not exactly, and that parents help their young survive. They sort animals into groups and use their five senses to observe. The click moment is when kids start inventing their own ideas from nature, like a helmet shaped like a turtle shell.

Our favorite ways to teach life science

First grade science should be hands-on, loud and full of questions. These moves make that happen.

Sing about mammals

Play the Mammal Song and have kids stand up every time they hear a feature, like fur or drinking milk. Afterwards, they list the features they remember and check them against the song.

Why it works: a catchy, repeating tune gives the brain a hook to hang words on, so sung text is remembered better (Wallace, 1994).

Sort the animal cards

Give each group animal pictures and three labels: mammals, fish, birds. Kids sort, then explain one clue that made them decide. The worksheet afterwards shows who really got it.

Why it works: kids understand an idea best when they touch it, then draw it, then write it, the order the U.S. Department of Education recommends for elementary math.

Snack-time plant parts

Bring in carrots, celery, lettuce and seeds. Kids match each snack to the plant part it comes from, then draw a plant and label the parts we eat. Delicious science!

Why it works: pairing a picture with each word gives kids two ways to remember it, a well-tested principle of how people learn (Mayer, 2009).

Questions teachers and parents ask

What is life science in 1st grade?

First grade life science covers plant and animal parts and their jobs, how young animals resemble their parents, how parents care for their young, animal groups and using the five senses to observe living things.

What are the parts of a plant for 1st grade?

First graders learn roots, stems, leaves, flowers and seeds. Roots take in water, the stem holds the plant up, leaves make food, flowers make seeds and seeds grow new plants.

How do animals use their body parts to survive?

Animals use body parts to eat, move, protect themselves and stay warm. A bird uses its beak to crack seeds, a turtle hides in its shell and a fish uses fins to swim.

How can I teach life science at home?

Go on a backyard or park walk and look for living things. Ask your child to describe them with their five senses and guess how each part helps the plant or animal survive.
