About this resource

What's inside this resource

Students start in a sporting-goods store, where balls, tents and shoes each have their own aisle, and learn that this sorting has a name: classification. The free one-page reading passage then turns to matter, explaining that it is anything with mass that takes up space, and sorts it two ways. One way is by state, as a solid, liquid or gas. The other sorts elements into metals and nonmetals by their properties. Two tree-style charts on page 2 show both systems, and iron appears in each.

Five question pages follow, with 22 questions in eight parts. Students answer multiple-choice questions, sort nine everyday items by state and complete word-bank sentences. Element clue cards for gold, bromine, nitrogen and carbon ask them to check a state and group and copy proof words. Later parts have students explain why gold and diamond land in different groups, fix three mistakes in a classmate's chart, build a classification chart of their own and re-sort it another way.

  • Grades 4–6: physical science reading on states of matter and classification
  • Eight pages: a passage, five question pages and a two-page answer key
  • Two PDFs: full color and print-friendly black and white

In the classroom

Teaching tips & learning objectives

Learning objectives

  • Define classification and matter in their own words.

  • Classify objects as solids, liquids or gases.

  • Sort elements as metals or nonmetals using their properties.

Teaching tips

  • Have students keep page 2 open while they work; questions across the set refer to both charts.

  • For the element clue cards, tell students to underline the electricity sentence first; the shape sentence decides the state.

  • If students stall on Part G, point back to how the passage splits "Sports" into "Ball sports" and "Water sports."

Skills covered

  • Classification: students group items by shared traits and explain the rule they used.

  • States of matter: students sort items such as maple syrup, a baseball bat and helium in a balloon.

  • Properties of elements: students use clues about shine and electricity to place gold, bromine, nitrogen and carbon.
