About this worksheet

What students practice

  • Students sort samples by observed color, texture, hardness, and flexibility.
  • Students combine property observations to judge materials for stated design needs.
  • Students use sample evidence to check sorting rules and claims about materials.

How to use

Read the test record together and keep it visible. Have students trace each sample letter through the four checks before comparing design choices.

Curriculum

Seven Samples at the Key Shop

Imani runs a key shop on a busy city street. She is planning tags, curved trim, and padding for a key pickup board. Before choosing materials, she checks seven safe samples with finished edges. She changes the sample but keeps her checks the same. She looks at each color and gently feels each surface. Then she uses the same gentle press and the same gentle bending test. She does not force a sample to bend. She records its color, texture, whether it dents, and whether it bends.

Color check
Purple: A foam sheet, D plastic strip, G fleece piece.
White: B foam sheet, E plastic tile.
Gray: C rubber pad, F plastic tile.

Texture check
Smooth: A, B, D, E.
Bumpy: C, F.
Fuzzy: G.

Press check
Dented (soft): A, B, C, G.
Did not dent (hard): D, E, F.

Bend check
Bent easily: A, B, C, D, G.
Stayed straight: E, F.

1.
Compare foam samples A and B. Which property would put them in different groups?
  • A. Texture
  • B. Hardness
  • C. Color
  • D. Flexibility
2.
Imani wants to compare matching colors for the board. Sort the seven samples by color.
A: foam sheetB: foam sheetC: rubber padD: plastic stripE: plastic tileF: plastic tileG: fleece piece

3.
Complete the sorting rules. Use the word bank. Two words will not be used.
Word bank: color · texture · hardness · flexibility

To separate pieces by how their surfaces feel, sort by  .
To separate pieces by how easily they bend, sort by  .

4.
Imani makes a tray for bumpy samples. Circle the two samples that belong.

ABCDEFG

Check the Material Plans

Use the test records to sort samples and judge which materials meet each plan.

5.
The shop needs separate trays for hard and soft samples. Sort by the press check, not by color or texture.
F: gray plastic tileB: white foam sheetD: purple plastic stripG: purple fleece pieceC: gray rubber padE: white plastic tileA: purple foam sheet
Hard: did not dentSoft: dented
6.
A curved trim design needs a purple, smooth sample that bends easily but does not dent. Which sample meets these needs?
  • A. D: plastic strip
  • B. A: foam sheet
  • C. G: fleece piece
  • D. E: plastic tile
7.
Imani makes three design trays. Ignore color and texture. Use the hardness and bending rules on the tray labels.
C: rubber padE: plastic tileA: foam sheetD: plastic stripG: fleece pieceF: plastic tileB: foam sheet
Padding samples: softCurved trim samples: hard and bend easilyFlat tag samples: hard and stay straight
8.
A new sample arrives. Which plan would let Imani compare its hardness fairly with the tested samples?
  • A. Use the same gentle press and check for a dent.
  • B. Use a stronger press and check for a dent.
  • C. Use the same bending test and check for a curve.
  • D. Use a gentle touch and check for a bumpy surface.
9.
One padding plan calls for a gray, bumpy material that dents under a gentle press. Should Imani choose C or F? Name the sample and use the records to explain why it fits better.

Find Mistakes and Missing Evidence

Check each claim against the records. Think about which property each test shows.

10.
A worker puts the smooth samples A, B, D, and E in a tray labeled “Soft.” Which correction agrees with the press check?
  • A. Move A and B to the hard tray.
  • B. Move B and D to the hard tray.
  • C. Move A and E to the hard tray.
  • D. Move D and E to the hard tray.
11.
A worker makes these groups:
Group 1: A, B, C, D, G
Group 2: E, F
Which rule fits the groups?
  • A. Group 1 is soft; Group 2 is hard.
  • B. Group 1 bends easily; Group 2 stays straight.
  • C. Group 1 is smooth; Group 2 is bumpy.
  • D. Group 1 is purple; Group 2 is gray.
12.
Imani records that a new sample is purple, dents, and bends easily. What should she do next to finish checking the four properties?
  • A. Press it gently to check for a dent.
  • B. Bend it gently to check for a curve.
  • C. Feel its surface gently to check its texture.
  • D. Look at it again to check its color.
13.
A worker says, “This new purple sample will be soft because A is purple and soft.” Is its color enough to decide? Use samples A and D as evidence. Tell what the worker should do next.
