Words sorting logic in Bubble Word Jam Level 688
In this puzzle, you group words that share a common idea. Some categories are broad, while others contain a nested subcategory with more specific words. Here we explain why each word belongs in its group.
TYPES OF SHIELDS
A shield is a piece of personal armor used to block attacks. The four words here are all specific kinds of shields.
- KITE belongs here because a kite shield is a large, curved shield shaped like a kite.
- HEATER belongs here because a heater shield is a medieval shield with a flat top and curved sides, often used in heraldry.
- SECURITY belongs here because a security shield is a modern term for a protective barrier, like a riot shield or a shield used by security forces.
- TOWER belongs here because a tower shield is an extremely large, full-body shield used by ancient soldiers (also called a pavise).
SCULPTING MATERIALS
This category groups materials that artists use to create sculptures. One of the words is also a subcategory.
- STONE belongs here because stone (like marble or granite) has been carved for sculptures for thousands of years. (The word STONE can be split into the chunks “st” and “one” in the game, but in this category it is a solid sculpting material.)
- BRONZE belongs here because bronze is a metal alloy commonly used for casting statues and sculptures.
- MARBLE belongs here because marble is a soft, white stone prized by sculptors like Michelangelo.
CLAY (subcategory of SCULPTING MATERIALS)
Clay is a natural, pliable material that hardens when fired. It is a specific type of sculpting material, so it appears as a nested group under SCULPTING MATERIALS.
- EARTHENWARE belongs under CLAY because earthenware is a type of clay pottery that is fired at low temperatures.
- RAKU belongs under CLAY because raku is a traditional Japanese pottery technique using special clay and rapid firing.
- SLAB belongs under CLAY because slab construction is a method of building clay forms from flat sheets (slabs) of clay.
- FIRE belongs under CLAY because fire is essential for hardening clay – the term “fire clay” refers to clay that can withstand high temperatures. (The word FIRE splits into “fi” and “re” in the game, but here it represents the kiln-firing process.)
ELEMENTARY PARTICLES
These are fundamental building blocks of matter in physics.
- ELECTRON belongs here because the electron is a subatomic particle with a negative charge, found orbiting the nucleus.
- GLUON belongs here because gluons are the particles that hold quarks together inside protons and neutrons.
- LEPTON belongs here because leptons are a family of elementary particles that includes electrons and neutrinos.
- NEUTRON belongs here because the neutron is a neutral particle found in the nucleus of an atom.
ORCHESTRA SECTIONS
An orchestra is divided into groups of instruments. Three words name the main sections. One section (violin) is actually a specific instrument, but here it acts as a subcategory for its parts.
- BRASS belongs here because the brass section includes trumpets, trombones, and tubas.
- PERCUSSION belongs here because the percussion section includes drums, cymbals, and other struck instruments.
- WOODWIND belongs here because the woodwind section includes flutes, clarinets, and oboes.
VIOLIN (subcategory of ORCHESTRA SECTIONS)
The violin is a string instrument, but in this puzzle it is a subcategory that groups the parts of a violin.
- FINGERBOARD belongs under VIOLIN because the fingerboard is the part of the violin where the player presses the strings.
- SOUNDPOST belongs under VIOLIN because the soundpost is a small wooden dowel inside the violin that transmits vibrations.
- TAILPIECE belongs under VIOLIN because the tailpiece holds the strings at the bottom of the instrument.
- SCROLL belongs under VIOLIN because the scroll is the decorative curled carving at the top of the violin’s neck.
THE AGE OF TECHNOLOGY
