3-LS1 From Molecules to Organisms: Structures and Processes
3-LS1-1
Develop models to desribe that organisms have unique and diverse life cycles but all have in common birth, growth, reproduction, and death.

- Changes organisms go through during their life form a pattern.
3-LS2 Ecosystems: Interactions, Energy, and Dynamics
3-LS2-1
Construct an argument that some animals form groups that help members survive.
Construct an argument that some animals form groups that help members survive.
- Being part of a group helps animals obtain food, defend themselves, and cope with changes. Groups may serve different functions and vary dramatically in size.
3-LS3 Heredity: Inheritance and Variation of Traits
3-LS3-1
Analyze and interpret data to provide evidence that plants and animals have traits inherited from parents and that variation of these traits exists in a group of similar organisms.
Use evidence to support the explanation that traits can be influenced by the environment.
Analyze and interpret data to provide evidence that plants and animals have traits inherited from parents and that variation of these traits exists in a group of similar organisms.
- Patterns are the similarities and difference in traits shared between offspring and their parents, or among siblings. The emphasis will be on non-human organisms.
Use evidence to support the explanation that traits can be influenced by the environment.
- An example of the environment affecting a trait could incldue normally tall plants grown with insufficient water are stunted.
- Another example would be a dog being given too much food and too little exercise may become overweight.
3-LS4 Biological Evolution: Unity and Diversity
3-LS4-1
Analyze and interpret data from fossils to provide evidence of the organisms and the environments in which they lived long ago.
Use evidence to construct an explanation for how the variations in characteristics among individuals of the same species may provide advantages in surviving, finding mates, and reproducing.
Construct an argument with evidence that in a particular habitat some organisms survive well, some survive less well, and some cannot survive at all.
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.
Analyze and interpret data from fossils to provide evidence of the organisms and the environments in which they lived long ago.
- Data can include type, size, and distributions of fossil organisms.
- Fossils could include marine fossils found on dry land, tropical plant fossils found in Arctic areas, and fossils of extinct organisms.
Use evidence to construct an explanation for how the variations in characteristics among individuals of the same species may provide advantages in surviving, finding mates, and reproducing.
- Cause and effect relationships could be plants that have larger thorns than other plants may be less likely to be eaten by predators and animals that have beeter camouflage coloration than other animals may be more likely to survive and therefore leave offspring.
Construct an argument with evidence that in a particular habitat some organisms survive well, some survive less well, and some cannot survive at all.
- Evidence could include needs and characteristics of the organisms and habitats involved. The organisms and their habitat make up a system in which the parts depend on each other.
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.
- Environmental changes could include changes in land characteristics, water distribution, temperature, food, and other organisms. This will not inlcude climate change.
