Content Source:

 PBS
Type: Audio/Video

Overview:

In this audio clip, students ask the question: Does air have weight? This is a great clip to engage students in a discussion on mass and density. 

Content Standard(s):
Science
SC2015 (2015)
Grade: 5
5 ) Construct explanations from observations to determine how the density of an object affects whether the object sinks or floats when placed in a liquid.

NAEP Framework
NAEP Statement::
P4.3: Matter exists in several different states; the most common states are solid, liquid, and gas. Each state of matter has unique properties. For instance, gases are easily compressed while solids and liquids are not. The shape of a solid is independent of its container; liquids and gases take the shape of their containers.

Unpacked Content
Scientific And Engineering Practices:
Constructing Explanations and Designing Solutions
Crosscutting Concepts: Cause and Effect
Disciplinary Core Idea: Matter and Its Interactions
Evidence Of Student Attainment:
Students:
  • Use data from observations to explain how the density of an object affects whether an object sinks or floats when placed in a liquid, like water.
Teacher Vocabulary:
  • density
  • volume
  • buoyancy
  • data
  • observe
  • explain
  • sink
  • float
  • mass
Knowledge:
Students know:
  • Objects are made of many tiny particles to small to be seen.
  • Some objects have many tiny particles compacted close together that causes the object to sink while other objects the same size may float because their tiny particles are less compact.
  • Some objects of the same size sink when others float.
  • Buoyancy is the ability of an object to float.
Skills:
Students are able to:
  • Predict the results of different types of objects being placed in water. Test the objects and communicate the results.
  • Use appropriate tools (Scale, balance, ruler, or graduated cylinder) to measure the weight, mass, and/volume of an object.
  • Construct an explanation to describe the observed relationship between density and the ability of an object to sink or float.
  • Identify the evidence that supports the explanation that density affects the ability of an object to sink or float.
Understanding:
Students understand that:
  • Cause and effect relationships are routinely identified and used to explain phenomenon like sinking and floating.
