Predict and investigate that water can change from a liquid to a solid (freeze), and back again (melt), or from a liquid to a gas (evaporation), and back again (condensation) as the result of temperature changes.
Construct an argument with evidence that some changes caused by heating or cooling can be reversed and some cannot.
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.
Develop a model to compare and contrast observations on the life cycle of different plants and animals.
Construct scientific arguments to support claims that some characteristics of organisms are inherited
from parents and some are influenced by the environment.
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.
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.
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.
Represent data tables and graphical displays to describe typical weather conditions expected during a particular season.
Obtain and combine information to describe climates in different regions of the world.
Make a claim about the merit of an existing design solution that reduces the impacts of a weather-related hazard.
Define a simple design problem reflecting a need or a want that includes specified criteria for success and constraints on materials, time, or cost.
Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem.
Plan and carryout fair tests in which variables are controlled and failure points are considered to identify aspects of a model or prototype that can be improved.
