3.LS3.B.1 Use evidence to construct an explanation for how the variations in characteristics among individuals of the same species may provide advantages in surviving and finding mates.

Lessons: Survival Clues: Fossils, Groups and Changing Habitats (Why do some animals in a family survive better?)

Practice: Survival Clues: Fossils, Groups and Changing Habitats workbook

3.LS3.C.1 Construct an argument with evidence that in a particular ecosystem some Organisms -- based on structural adaptations or behaviors -- can survive well, some survive less well, and some cannot.

Lessons: Who Lives Here? (Who can live here, and who can't?)

Practice: Who Lives Here? workbook

3.LS3.D.1 Make a claim about the merit of a solution to a problem caused when the environment changes and the types of plants and animals that live there may change.

Lessons: Survival Clues: Fossils, Groups and Changing Habitats (What happens when a habitat changes?)

Practice: Survival Clues: Fossils, Groups and Changing Habitats workbook

3.PS1.B.1 Construct an argument with evidence that some changes caused by heating or cooling can be reversed and some cannot.

Lessons: Earth and Sky at Home (How do crystals grow?, How does a cloud form?) (partly) · Winter Science at Home (Can you make frost in a can?, Why does salt melt ice?) (partly)

Practice: Earth and Sky at Home workbook · Winter Science at Home workbook

3.PS2.B.1 Plan and conduct investigations to determine the cause and effect relationship of electric or magnetic interactions between two objects not in contact with each other.
