Habitats and Adaptations Target 3rd Grade
Content Topics Biomes (Habitats) Adaptations Inheritance
Biome (Habitat) A biome is a major terrestrial or aquatic life zone, characterized by: the physical environment including vegetation and precipitation
Tropical Rainforest: Temperature range Precipitation
Savanna: Temperature range Precipitation Fire
Desert: Temperature range Precipitation
Chaparral (Specific to California): Temperature range Precipitation Fire
Temperate grassland: Temperature range Precipitation Fire
Temperate Deciduous Forest – Fall season Temperature range Precipitation
Deciduous Forest in winter
Coniferous Forest: Temperature range Precipitation
Tundra: Temperature range Precipitation
Sample Questions: Which Biome do you think has the most animals and plants? Why? Do you think animals and plants need to have special features (adaptations) to live in different habitats?
Adaptations Adaptations are features of animals and plants that make them survive longer in their environment. Organisms adapt to their environment to become better fitted to survive and pass their genes on to the next generation through reproduction.

Animal Camouflage
Sample Questions: Can you see any animals in these pictures? If you were a predator would you be able to pick out your dinner easily in these pictures?
Inheritance and Survival Inheritance - is the process of genetic traits being passes from parent to offspring. Survival – is to live or exist.
Inheritance and Survival What do you notice?
Predator captures easy prey Remaining mice reproduce
Higher proportion of white mice in successive generations Surviving individuals reproduce Killed by predator Higher proportion of white mice in successive generations
Sample Questions What if the environment changes? What will happen to the population of mice?
NGSS Standard: 3-LS4-3 - Construct an argument with evidence that in a particular habitat some organisms can survive well, some survive less well, and some cannot survive at all.
