4How many more drops did the higher material bar absorb?
5Which rule makes an absorbency comparison fair?
6Which property word belongs in the observation record for clear plastic?
7How can a class check the claim that clear plastic is transparent?
8What evidence-based reason supports using metal spoon in a design?

About this worksheet
Materials can be described by properties that we observe or test: hard or soft, rough or smooth, stiff or flexible, absorbent or waterproof, transparent or opaque. First graders often name the object instead of the material, or choose a favorite material without connecting it to a purpose. This worksheet keeps those ideas separate. Students identify the property shown by a short test, compare results, sort materials, and select a useful property for a simple design need. Support versions feature large contrasts such as soft cloth and hard metal. Challenge versions use properties that require evidence, such as absorbency or flexibility, and ask for a fair comparison. Exact graphs appear only when they display actual recorded test results. The page does not claim that every object made from a material behaves identically. Encourage your child to use comparison language: more flexible than, less absorbent than, or smoother than.
What your child will learn
Describe observable material properties
Use test results as evidence
Sort materials by one stated property
Choose a property that fits a purpose
Worked example
A paper towel gains more water than wax paper in the same test. That evidence shows the paper towel is more absorbent.
Common mistake
Choosing a material by its color or familiarity when the design problem requires a different useful property.
Helpful hint
Name the test result, then connect it to the property.
