Sample Assessment Ideas

Sample Assessment Ideas

  • Students list three animals that no longer exist on Earth and three animals that now exist.

  • Students watch a movie about prehistoric times. Pick out three things that are not true about our Earth today.

Expanded Sample Assessment Idea

red rule

Expanded Sample Assessment Idea

  • Students use an assortment of pictures or toys, to separate animals that no longer live on Earth from those animals that are now living on Earth.

Procedure

Students will:

  1. Study pictures or toys of animals (some that currently live on Earth and some that no longer live on Earth).

  2. In a group, sort the animals into those currently living on Earth and those no longer living on Earth.

  3. Individually sort a subset of 5 animal pictures or toys into groups of those currently living on Earth and those no longer living on Earth; make a poster using the animal pictures; discuss why they choose to put the animals in each category.

Reflection and Revision

Given 4–5 new animal pictures or toys, how do you decide where they should be placed in the poster?

Standards Cross-References
( Alaska Department of Education & Early Development Standards)

National Science Education Standards

An organism’s patterns of behavior are related to the nature of that organism’s environment, including the kinds and numbers of other organisms present, the availability of food and resources, and the physical characteristics of the environment. When the environment changes, some plants and animals survive and reproduce, and others die or move to new locations. (Page 129)

 

Benchmarks

Different plants and animals have external features that help them thrive in different kinds of places. (Page 123)

Some kinds of organisms that once lived on Earth have completely disappeared, although they were something like others that are alive today. (Page 123)
