Product description

From the author

Review fifteen fossil and paleontology terms with a word search, a definition-clued word scramble and a crossword. Three two-page PDFs each contain a puzzle and its solution, for six pages total.

Terms include fossil, paleontologist, ammonite, trilobite, dinosaur, bones, mold, cast, trace fossil, carbonization, permineralization, amber, index fossils, extinction and evolution. Use the short definitions for vocabulary review, then invite students to explain a fossil type in their own words.

Teaching tips & learning objectives

Learning objectives

  • Match fossil vocabulary to short definitions, such as identifying a cast as a filled imprint and a mold as an empty one

  • Spell fifteen paleontology terms correctly, including long ones like permineralization and carbonization

  • Recognise the specialist words for extinct organisms and for the scientist who studies them

Teaching tips

  • All three puzzles use the same fifteen words, so run the crossword first and the word search last - by the third pass students are checking spelling rather than recalling meaning

  • The clues are definitions rather than descriptions, so the crossword doubles as a vocabulary check and can be marked as one

  • The scramble prints a blank of the correct length under each item, which quietly gives away word length - useful as scaffolding, worth covering if the sheet is being used to assess

Skills covered

  • Fossil vocabulary - fifteen terms including mold, cast, trace fossil, carbonization, permineralization and index fossils are matched to one-line definitions in the crossword.

  • Spelling long technical words - the scramble asks students to unjumble ENIREAZTNIMLOIARP into permineralization and OAANBTCOIIRZN into carbonization, letter by letter.

  • Visual word recognition - the word search sets the same terms in a letter grid, which asks students to recognise each word by shape after they have met it by definition.

Good to know

Questions teachers ask about this resource

In Fossils and Paleontology Word search, scramble and crossword, do the three puzzles use the same word list?

Yes - all fifteen terms appear in each one. The crossword clues them by definition, the scramble jumbles their letters with the same definitions attached, and the word search hides them in a grid, so the set works as three passes over one vocabulary list.

How demanding is the vocabulary?

It reaches well past dinosaur. Alongside fossil, bones and amber sit ammonite, trilobite, trace fossil, index fossils, carbonization and permineralization - terms from a middle-grade earth science unit rather than an early-years dinosaur topic.

In Fossils and Paleontology Word search, scramble and crossword, how are the clues written?

As compressed definitions, two or three words each: "Filled imprint" for cast, "Empty imprint" for mold, "Dates rock layers" for index fossils, "Species dies" for extinction. That makes the puzzles a vocabulary check rather than a general knowledge quiz.
