Overview

When discussing material properties, most of us usually think of solid materials and material properties such as hardness, flexibility, or strength. However, liquids are characterized by distinct properties, too. Some of these properties overlap with those of solids, like density or transparency, but others are more specific to liquids. Viscosity—the resistance of a fluid to flow—and surface tension, are two examples of properties that are specifically used to characterize liquids. In this lesson plan, students will investigate the properties of different liquids by pouring them, smelling them, and investigating their densities by stacking them on top of each other.

NGSS Alignment

This lesson helps students prepare for these Next Generation Science Standards Performance Expectations:
  • 2-PS1-1. Plan and conduct an investigation to describe and classify different kinds of materials by their observable properties.
This lesson focuses on these aspects of NGSS Three Dimensional Learning:

Science & Engineering Practices Disciplinary Core Ideas Crosscutting Concepts
Planning and Carrying Out Investigations.
Plan and conduct an investigation collaboratively to produce data to serve as the basis for evidence to answer a question.
PS1.A: Structure and Properties of Matter.
Different kinds of matter exist and many of them can be either solid or liquid, depending on temperature. Matter can be described and classified by its observable properties.
Patterns.
Patterns in the natural and human designed world can be observed.

Materials


Materials needed for the 'Investigate the Properties of Liquids'  lesson plan.

Materials for each group of 2-3 students:

  • Dark corn syrup, 1 Tbsp.
  • Dish soap, 1 Tbsp.
  • Water, 1 Tbsp.
  • Vegetable oil, 1 Tbsp.
  • Plastic cup, 16-oz
  • Liquid food coloring (green)
  • Mini plastic cups with lids, 2-oz (10)
  • Paper towels

Materials for teacher:

  • Mini plastic cups with lids, 2-oz (4); put 1 Tbsp. of each liquid in its own mini cup
  • Tablespoon
  • One extra mini cup with lid, 2-oz
  • Apple cider vinegar, 1 Tbsp.
