What Your Child Will Learn

Match everyday examples to Newton's three laws, measure how force changes acceleration, and launch balloon rockets of different sizes.

  • Newton's laws explain inertia, how force causes acceleration, and action-reaction pairs.
  • Acceleration grows with force: for a 1 kg cart, 8 N gives 8 m/s².
  • Balloon rockets show action and reaction. More air gives a bigger push and a longer flight.

Why it matters

Why This Matters for Kids

  • How everything moves

    Newton's laws explain motion in sports, cars, rockets and playgrounds.

  • Force and acceleration

    Measuring force and acceleration builds data and math skills in science.

  • Engineering and space

    Rockets and seat belts are designed using Newton's laws.

Inside Newton's Laws of Motion

How the Course Works

Each level has a short read-aloud lesson, an interactive experiment and a mini quiz.

  1. Step 1 · Lesson

    Three Laws

    Law 1 (inertia): things keep doing what they're doing unless a force acts on them.

  2. Step 2 · Experiment

    Law Match

    Newton's laws are everywhere! Which law does each example show best?

  3. Step 3 · Lesson

    Force and Acceleration

    Acceleration is how quickly speed changes.

  4. Step 4 · Experiment

    Push Meter

    Let's push a 1 kg cart with different forces and measure its acceleration.

  5. Step 5 · Lesson

    Balloon Rockets

    A balloon rocket pushes air backward. The air pushes the balloon forward!

  6. Step 6 · Experiment

    Rocket Launch

    Let's tape balloons to a straw on a string and launch them, blowing them up more each time.

A Peek Inside the Lesson

This is the real lesson text your child hears, read aloud by a friendly voice.

Three Laws

Law 1 (inertia): things keep doing what they're doing unless a force acts on them.

Law 2: force = mass × acceleration. A bigger force gives a bigger speed-up.

Law 3: every action has an equal and opposite reaction.

Force and Acceleration

Acceleration is how quickly speed changes.

For the same mass, double the force gives double the acceleration.

Force is measured in newtons (N), named after Isaac Newton.

Balloon Rockets

A balloon rocket pushes air backward. The air pushes the balloon forward!

That's Newton's third law: action and reaction.

More air pushed out means a bigger push and a longer flight.

For parents

Try It at Home

Learning sticks best when kids use it in real life. Here are simple ideas from this course.

Parent Tip

Tape a straw to a balloon, thread it on a string across a room and let it go. Try different balloon sizes and talk about Newton's third law.

Law Match

  1. Put a coin on a card on top of a glass.
  2. Flick the card away fast.
  3. The coin drops into the glass: inertia!

Newton's laws explain inertia, how force causes acceleration, and action-reaction pairs.

Push Meter

  1. Roll a toy car with one finger flick, then two fingers.
  2. Use a ruler to measure how far it goes.
  3. Add weight to the car and try again.

Acceleration grows with force: for a 1 kg cart, 8 N gives 8 m/s².

Rocket Launch

  1. Thread a string through a straw and tie it across a room.
  2. Tape a blown-up balloon to the straw (hold the end shut).
  3. Let go and measure how far it zooms!

Balloon rockets show action and reaction. More air gives a bigger push and a longer flight.

Frequently Asked Questions

What age is this course for?

Newton's Laws of Motion is a grade 6 science course for kids ages 11–12. That is Year 7 science in the UK and Year 6 in Australia. It also works well for review in the next grade, or as a challenge for a confident younger learner.

What will my child learn?

Match everyday examples to Newton's three laws, measure how force changes acceleration, and launch balloon rockets of different sizes. Along the way they practice: Newton's laws explain inertia, how force causes acceleration, and action-reaction pairs; Acceleration grows with force: for a 1 kg cart, 8 N gives 8 m/s²; Balloon rockets show action and reaction. More air gives a bigger push and a longer flight.

How long does the course take?

About 25 minutes in total, split into 3 short levels. Most kids finish it over two or three sessions. Progress is saved, so they can stop any time and pick up where they left off.

Is this course free?

Newton's Laws of Motion is part of SkillBloom Premium, which unlocks every course in every subject. Each subject also has free courses, so your child can try SkillBloom before you decide.

Does my child need to read well to use it?

No. Every lesson has a friendly read-aloud voice, questions are read aloud too, and the pictures help kids follow along. Confident readers can turn the voice off.

Can we use it for homeschool?

Yes. SkillBloom is built for homeschooling families. Kids work through lessons, games and quizzes on their own, and the parent dashboard shows what they finished and which skills need more practice. It works on phones, tablets and laptops.
