Overview

In this lesson, students will be able to plan and carry out an investigation to discover and compare the properties of liquids. Students will develop an understanding that liquids, like solids, have their own characteristic properties.

Students investigate three clear colorless liquids: water, mineral oil, and corn syrup. Students place drops of each liquid on the surface of a zip-closing plastic bag and see that the liquids look and act differently. Students tilt the bag and see that the liquids move down the plastic at different rates. Finally, students see a demonstration in which a drop of food coloring is placed in each liquid, and students make observations about the different ways the food coloring looks in each.

SC15.2.1

Conduct an investigation to describe and classify various substances according to physical properties (e.g., milk being a liquid, not clear in color, assuming shape of its container, mixing with water; mineral oil being a liquid, clear in color, taking shape of its container, floating in water; a brick being a solid, not clear in color, rough in texture, not taking the shape of its container, sinking in water).

Knowledge

Students know:
  • Different kinds of matter exists.
  • Properties of both solids (opaque, transparent, translucent, rough, smooth, float, sink, has its own shape) and liquids (color, assumes shape of container, opaque, transparent, translucent).
  • Many types of matter can be either solid or liquid, depending on temperature.

Skills

Students are able to:
  • Plan and conduct an investigation to produce data that is used to describe and classify substances according to physical properties.

Understanding

Students understand that:
  • Observable patterns in the properties of materials provide evidence to classify the different kinds of materials.
