Objectives

  1. Investigate a variety of objects to identify that most things are made of parts

Indicator

  • 3. Examine a variety of physical models and describe what they teach about the real things they are meant to resemble.

Objectives

  1. Explain that a model of something is different from the real thing but can be used to learn something about the real thing.
  1. Realize that one way to describe something is to say how it is like something else.

  1. Describe the changes that occur to water found anywhere.

Standard 3.0 Life Science

Topic

C. Genetics

Indicator
