Energy All Around

Forms of energy and where it comes from

Energy is not a substance, which is why it is hard to teach. It is a quantity that stays constant while changing form, and most of this unit is about tracking those changes.

It covers the forms energy takes, where the energy people use actually comes from, food as the body's fuel, electrical safety, and why saving energy is worth doing.

This unit breaks down into 21 short steps and 127 questions, starting at difficulty 1 and building to 3. Below you can see exactly what it covers, how the path is structured, and worked examples with explanations.

What this unit covers

  • Where Energy Comes From
  • Using Electricity Safely
  • Forms of Energy
  • Saving Energy
  • Food as Fuel

Where this fits

Pairs with Forces and Movement. Physics's Energy and Its Forms takes the same material further.

Where people slip

Energy is not used up. It changes form and spreads out, and what people call wasted energy has usually just become heat that is too dispersed to be useful.

How the unit is structured

Energy All Around runs as 21 short steps that unlock in order. 15 are practice rounds and 6 are challenge rounds that pull together everything before them. Questions start at difficulty 1 and climb to 3 as you progress.

    • Lightcorrect
    • Heatcorrect
    • Soundcorrect

    Each object releases a different form of energy, such as light, heat, sound, or motion.

  • Odd one outLevel 2

    12. Which of these does NOT give off heat?

    • A mirrorcorrect
    • An oven
    • A campfire
    • A light bulb that is on

    A mirror only reflects light and stays cool, while the others give off heat.

Saving Energy

  • Build the sentenceLevel 1

    13. Build a helpful energy-saving tip.

    Answer: Open the curtains to use daylight

    Opening the curtains lets you use free daylight instead of turning on lamps.

  • Guess the numberLevel 1

    14. How many lights should be left on in a room that nobody is in?

    Answer: 0 lights

    An empty room needs no lights, so turning them all off saves energy.

  • Choose all that applyLevel 2

    15. Which of these help save energy at home? Pick all that apply.

    • Unplug devices you are not usingcorrect
    • Turn off the heat when you leave homecorrect
    • Take shorter showerscorrect
    • Leave the fridge door open

    Unplugging, turning off the heat when out, and shorter showers all save energy.

  • Fact or fibLevel 2

    16. Opening the curtains to let in daylight lets you switch off some lamps and save energy.

    Answer: True

    Free daylight means you can turn off lamps and use less electricity.

  • Fill the blankLevel 2

    17. ____ bulbs give the same light but use much less energy than old bulbs.

    • LEDcorrect
    • Bigger
    • Hotter
    • Older

    LED bulbs give bright light while using far less energy.

  • Multiple choiceLevel 2

    18. Why is saving energy good for the planet?

    • It reduces pollution from making energycorrect
    • It makes more trash
    • It uses up fuel faster
    • It heats the Earth faster

    Using less energy means less fuel is burned, which makes less pollution.

Using Electricity Safely

  • Fill the blankLevel 1

    19. When unplugging a device, pull the ____, not the cord.

    • plugcorrect
    • wall
    • wire
    • switch

    Pulling the plug instead of the cord keeps the cord from getting damaged.

    20. Why should you keep water away from electrical outlets?

    • Water can carry electricity and give a shockcorrect
    • Water makes the outlet stronger
    • Water cleans the electricity

    21. Which of these are safe electricity habits? Pick all that apply.

    • Keep water away from outletscorrect
    • Pull the plug, not the cord
    • Tell an adult about a damaged cordcorrect

    Safe habits keep water, forks, and damaged cords away from electricity.

  • Fact or fibLevel 2

    22. It is safe to use a charger with a torn, damaged cord.

    Answer: False

    A damaged cord can cause a shock or fire, so it should not be used.

  • Match the pairsLevel 2

    23. Match each electrical situation to the safe response.

    Answer: A cord looks cracked or damaged = Do not use it; tell an adult; You want to unplug a charger = Pull the plug, not the cord; You finished toasting bread = Unplug the toaster before cleaning it; A cord stretches across a doorway = Move it so no one trips

    Knowing the safe response to each situation keeps you safe around electricity.

  • Odd one outLevel 2

    24. Which of these is NOT a safe way to use electricity?

    • Put metal objects into a socketcorrect
    • Ask an adult for help
    • Keep cords away from water

    Putting metal into a socket is very dangerous and can cause a shock.

Where Energy Comes From

  • Fact or fibLevel 1

    25. A battery is a store of energy you can carry around.

    Answer: True

    A battery holds stored energy so a device can work without being plugged in.

  • Multiple choiceLevel 1

    26. Where does most of Earth's energy first come from?

    • The Suncorrect
    • The Moon
    • The wind

    They are called fossil fuels because they formed from ancient living things.

  • Guess the numberLevel 2

    29. Most large wind turbines that make electricity have how many blades?

    Answer: 3 blades

    Most modern wind turbines use three blades, which is a steady and efficient design.

  • Match the pairsLevel 2

    30. Match each power source to what it uses to make energy.

    Answer: Solar panel = Sunlight; Wind turbine = Wind; Hydro dam = Moving water; Wood stove = Wood

    Each of these gets its energy from a different natural source.

Where these questions come from. Each unit starts as a plan of the concepts it should cover and the difficulty it should span. Questions are written against that plan with AI assistance, then checked by a validator that rejects anything without a single defensible answer, an explanation, or plausible wrong options. How we write questions sets out the whole process, and corrections are fixed in the bank and reach the site and the app the same day.
