From our teachers' playbook

Pushes, pulls, and big what-ifs

What do 3rd graders learn in science?

Third grade science gets kids testing like real scientists. They study forces and motion, pushes, pulls, gravity and friction, and predict what happens when one changes. They explore life cycles, how traits pass from parents to young, and how animals survive in their habitats. Many classes also study weather and climate, reading data to compare places. The click comes when kids run a fair test, change only one thing, and see that their prediction was right (or wonderfully wrong).

How we make 3rd grade science stick

Third graders want to touch, test and argue about it. These moves give them all three.

Predict, test, record

Roll a toy car down a ramp on carpet, then on foil, then on sandpaper. Kids predict, test and record the distance each time. The friction lesson teaches itself, and so does the idea of a fair test.

Why it works: going from real objects to pictures to symbols is a core recommendation of the U.S. Department of Education's elementary math guide.

Label the diagram

After a hands-on investigation, kids label a diagram of what they saw: the arrows for push and pull, or the parts of a flower. Connecting the real thing to the drawing locks in the vocabulary.

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

Sing the cycles

Cycles have steps, and steps love a song. A water cycle song a few times that week helps kids remember evaporation, condensation and precipitation in order.

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

3rd grade science questions

What science topics are taught in 3rd grade?

Most 3rd grade classes cover forces and motion, life cycles, inherited traits, animal adaptations and habitats, and weather and climate. Some also include fossils, magnets, and plant parts.

How do you explain gravity to a 3rd grader?

Gravity is a pull that brings things toward Earth. It's why a dropped ball falls instead of floating away. Try dropping different objects and talk about why they all fall down.

What is a fair test in 3rd grade science?

A fair test changes only one thing at a time and keeps everything else the same. If you test which surface makes a car roll farthest, use the same car, ramp and push each time.

How can I support 3rd grade science at home?

Ask lots of "what do you think will happen?" questions while cooking, playing or walking outside. Watch the weather together, plant seeds, or race toy cars on different floors. Curiosity is the biggest skill.
