Designing an Absorbency Test

Learning Resource Type

Classroom Resource

Subject Area

Science

Grade(s)

2

Overview

Students will plan and conduct an absorbency test on four different materials and be able to explain that when testing materials to learn about their properties, the materials need to be tested in the same way. Students will be able to explain that since the materials are made from different substances, they absorb different amounts of water.

Knowledge

Students know:
  • Properties of materials (e.g., strength, flexibility, hardness, texture, absorbency) Different uses for the materials.
  • The relationship between properties of materials and some potential uses (metal is strong, paper is absorbent, etc.).

Skills

Students are able to:
  • Conduct simple tests to collect and display data about the physical properties of various materials.
  • Analyze data to identify and describe relationships between properties and their potential uses.

Understanding

Students understand that:
  • Simple tests can be designed to gather evidence about the relationship between properties of materials and their intended uses.
