AAAS BENCHMARKS COVERED*

Scientific investigations may take many different forms, including observing what things are like or what is happening somewhere, collecting specimens for analysis, and doing experiments. Investigations can focus on physical, biological, and social questions. A great variety of kinds of living things can be sorted into groups in many ways using various features to decide which things belong to which group.Features used for grouping depend on the purpose of the grouping. For any particular environment, some kinds of plants and animals survive well, some survive less well, and some cannot survive at all. Some source of “energy” is needed for all organisms to stay alive and grow.

AAAS BENCHMARKS COVERED*

For any particular environment, some kinds of plants and animals survive well, some survive less well, and some cannot survive at all. Individuals of the same kind differ in their characteristics, and sometimes the differences give individuals an advantage in surviving and reproducing. Keep records of their investigations and observations and not change the records later.

Lesson 4 - Adaptation

OBJECTIVE

AAAS BENCHMARKS COVERED*

Scientists’ explanations about what happens in the world come partly from what they observe, partly from whatthey think. Sometimes scientists have different explanations for the same set of observations.That usuallyleads to their making more observations to resolve the differences.Changes in an organism’s habitat are sometimes beneficial to it and sometimes harmful.Tables and graphs can show how values of one quantity are related to values of another.Use numerical data in describing and comparing objects and events.Things can be done to materials to changesome of their properties, but not all materials respond the same way to what is done to them.

Lesson 5 - Structure and Function

OBJECTIVE

Students will learn the rules of classification and use them to classify objects, animals, and plants.

AAAS BENCHMARKS COVERED*

A great variety of kinds of living things can be sorted into groups in many ways using various features to decide which things belong to which group. Features used for grouping depend on the purpose of the grouping. For any particular environment, some kinds of plants and animals survive well, some survive less well, and some cannot survive at all. Insects and various other organisms depend on dead plant and animal material for food.
