Describe a waste stream.

• Identify sources of waste derived from the use of natural resources.
• Identify those items that can be recycled and those that can not.
• Describe how everyday activities may affect the environment

Explain how living things are dependent upon other living and nonliving things for survival. 

• Explain what happens to an organism when its food supply, access to water, shelter or space (niche / habitat) is changed.
• Identify similarities and differences between living organisms, ranging from single-celled to multi-cellular organisms through the use of microscopes, video, and other media.

Explain how freshwater organisms are adapted to their environment. 

• Explain the life cycles of organisms in a freshwater environment

PATTERNS

Identify observable patterns in the physical characteristics of plants or groups of animals.

• Distinguish between scientific fact and opinion.
• Ask questions about objects, organisms, and events.
• Understand that all scientific investigations involve asking and answering questions and comparing the answer with what is already known.
• Plan and conduct a simple investigation and understand that different questions require different kinds of investigations.
• Use simple equipment (tools and other technologies) to gather data and understand that this allows scientists to collect more information than relying only on their senses to gather information.
• Use data/evidence to construct explanations and understand that scientists develop explanations based on their evidence and compare them with their current scientific knowledge.
• Communicate procedures and explanations giving priority to evidence and understanding that scientists make their results public, describe their investigations so they can be reproduced, and review and ask questions about the work of other scientists.

Identify differences in the life cycles of plants and animals.

MODELS

Construct and interpret models and diagrams of various animal and plant life cycles.

• Distinguish between scientific fact and opinion.
