Students examine plants and animals to determine the function of structures such as teeth and beaks. These structures are related to the classification of animals and plans, an organism's ability to adapt to different environments, and its habitat. Students begin to explore how diverse living things are alike and how they are different.
Lesson 1: What Big Teeth You Have
Lesson 1 -What Big Teeth You Have
OBJECTIVE
Students will identify the function of each type of tooth in their mouths and in those of familiar animals.

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.

Organisms interact with one another in various ways besides providing food. Many plants depend on animals for carrying their pollen to other plants or for dispersing their seeds.Individuals of the same kind differ in their characteristics, and sometimes the differences give individuals an advantage in surviving and reproducing. Seeing how a model works after changes are made to it may suggest how the real thing would work if the same were done to it. Make sketches to aid in explaining procedures or ideas.

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.
