Clues for every answer

A one-line clue for every answer, easy to hard. They're the same clues the game's 💡 Hint shows, so you can read them out when you run your own game.

Atom

Basic particle of a chemical element, with a nucleus surrounded by electrons.

Sun

The star at the centre of our solar system.

Moon

Earth's only natural satellite, whose pull helps cause the tides.

Earth

The third planet from the Sun and the only one known to hold life.

Water

Clear liquid with the chemical formula H2O.

Fire

Burning: the rapid reaction of a fuel that gives off heat and light.

Wind

Air moving across the surface of the Earth.

Rain

Drops of water that form in the air and fall to the ground.

Snow

Ice crystals that fall from clouds and build up on the ground.

Root

Part of a plant, usually underground, that takes in water and nutrients.

Flower

Part of a plant used for reproduction, with petals that often attract pollinators.

Seed

Part of a plant holding a tiny embryo that can grow into a new plant.

Blood

Red liquid pumped by the heart that carries oxygen around the body.

Bone

Hard tissue that makes up the skeleton.

Skin

The body's outer covering, which protects everything inside.

Force

A push or a pull that can change how something moves.

Wave

A disturbance that carries energy from place to place, like ripples on water.

Heat

Energy passing between an object and its surroundings in a way other than doing work.

Light

Electromagnetic radiation that our eyes can see.

Sound

Pressure waves travelling through air, water or solids that our ears can hear.

Oxygen

Gas with the chemical symbol O that we need to breathe.

Carbon

Element with the symbol C, found in all known life and in diamond and graphite.

Gravity

The force that draws objects towards each other.

Eclipse

When one object in space blocks the light from another, like the Moon passing in front of the Sun.

Erosion

Wearing away of soil and rock by water, wind or ice, which then carry it away.

Photon

A tiny packet of light energy.

Neuron

Nerve cell that passes electrical signals around the body.

Bacteria

Tiny living things usually made of a single cell; some cause illness.

Cell

The basic unit of life; every living thing is made of them.

Circuit

Loop of electronic parts joined by wires, with electric current flowing round it.

Isotope

Version of an element with a different number of neutrons in its nucleus.

Molecule

Group of two or more atoms held together by chemical bonds, like H2O.

Hormone

Chemical messenger sent to distant parts of the body to control what they do.

Enzyme

Protein that speeds up chemical reactions in living things.

Comet

Icy object that can grow a tail of gas and dust as it nears the Sun.

Magnet

Object that pulls on iron and has a north and a south pole.

Fossil

Preserved remains or traces of a living thing from long ago.

Nucleus

Tiny dense centre of an atom, made of protons and neutrons.

Friction

Force that resists two surfaces sliding against each other.

Electron

Tiny particle with a negative charge, found in every atom.

Photosynthesis

How plants use sunlight, water and carbon dioxide to make sugar and give off oxygen.

Ecosystem

All the living things in an area together with their surroundings, working as one.

Chromosome

Long strand of DNA carrying genes, found inside cells.

Metabolism

All the chemical reactions that keep a living thing alive, like turning food into energy.

Thermodynamics

Branch of physics about heat, work and energy.

Electrolysis

Using a direct current to drive a chemical reaction that would not happen on its own.

Astrophysics

Science that uses physics and chemistry to explain stars, galaxies and the universe.

Magnetism

Invisible force made by moving electric charges, the one that turns a compass needle.

Crystallography

Science that studies how solids are built at the level of atoms, often using X-rays.

Geomorphology

Study of how the shape of the land forms and changes over time.

Biochemistry

Study of the chemical processes inside living things, from proteins to DNA.

Neurology

Branch of medicine that deals with the brain and nerves.

Spectroscopy

Measuring how matter absorbs or gives off light at different wavelengths.

Tectonics

Study of how the Earth's crust is built and how it changes over time.

Geophysics

Study of the Earth's physical processes and properties, from its magnetic field to earthquakes.

Refraction

Bending of a wave, like light, as it passes from one material into another.

Combustion

Chemical reaction in which something burns, giving out heat.

Microbiology

Study of microscopic living things such as bacteria.

Seismology

Study of earthquakes and the waves they send through the Earth.

Nanotechnology

Working with matter at the scale of single atoms and molecules.
