Overview

Experiments are cool with a curious baby polar bear and his who, what, when, where, and why questions about the three states of matter. In this interactive lesson, students get hands-on with ice and record their observations through drawing and writing.

ELA21.2.4

Orally answer who, what, when, where, why, and how questions about a text or conversation, using complete sentences to provide key ideas and details.

UP:ELA21.2.4

Vocabulary

  • Orally
  • Who, what, when where, why, and how questions
  • Complete sentences
  • Key ideas
  • Key details

Knowledge

Students know:
  • Key ideas and details should be included when answering questions.
  • Complete sentences, which contain a subject and a predicate, should be used when answering questions.
  • Who, when, and where questions will have a concrete, objective answer.
  • What, why, and how questions may have a more abstract, subjective answer.

Skills

Students are able to:
  • Orally answer questions about a text or conversation using complete sentences that provide information about key ideas and details.
  • Orally answer who, what, when, where, why, and how questions about a text or conversation with appropriate key ideas and details.

Understanding

Students understand that:
  • When answering who, what, when, where, why, and how questions they should provide key ideas and details from a text or conversation to demonstrate their comprehension.
  • Speaking in complete sentences helps them clearly communicate their message and their understanding.

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).

Vocabulary

  • Solid
  • Liquid
  • Physical Properties
  • Investigate
  • Classify
  • Opaque
  • Transparent
  • Translucent
  • Rough
  • Smooth
  • Float
  • Sink
  • Shape
  • Various
  • Substances
  • Conduct
  • Describe

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.

SC15.2.4

Provide evidence that some changes in matter caused by heating or cooling can be reversed (e.g., heating or freezing of water) and some changes are irreversible (e.g., baking a cake, boiling an egg).

UP:SC15.2.4

Vocabulary

  • Properties
  • Evidence
  • Change
  • Matter
  • Heating
  • Cooling
  • Reversible
  • Irreversible

Knowledge

Students know:
  • Characteristics of materials before heating or cooling.
  • Characteristics of materials after heating and cooling.
  • Characteristics of materials when heating or cooling is reversed.

Skills

Students are able to:
  • Analyze evidence to support a claim that heating and cooling causes change in matter.

Understanding

Students understand that:
  • Heating or cooling a substance may cause changes that can be observed. Sometimes these changes are reversible and sometimes they are not.
