Life Cycles
Animal & Plant Life Cycles
Build and compare life-cycle models to explain how organisms begin life, grow and change, reproduce, and eventually die while offspring begin a new generation.
46 min · ~10 min prep · 6 materials
Traits
Inherited Traits & Variation
Use plant and animal data to find inherited-trait patterns, variation among similar organisms, and evidence that environmental conditions can influence how traits develop.
45 min · ~8 min prep · 5 materials
Survival & Environment
Adaptations & Survival in Habitats
Use repeated camouflage data and organism-needs evidence to build a calibrated habitat-survival argument.
45 min · ~10 min prep · 3 materials
Animal Behavior
Why Animals Live in Groups
Analyze repeated observations and build an argument about how some animal groups can help members survive.
45 min · ~8 min prep · 4 materials
Animal Diversity
Animal Classification: Vertebrates & Invertebrates
Use body-structure evidence to classify animals as vertebrates or invertebrates and then compare familiar groups such as mammals, birds, insects, arachnids, mollusks, and crustaceans.

Ecosystems and Survival
Changing Habitats: When a Need Is Missing
Use organism-and-resource evidence to explain why the same habitat change can help some organisms, challenge others, and make survival impossible for others.
