In this Grade 5 lesson from Science: A Closer Look, Chapter 2, students explore how adaptations help organisms survive in their ecosystems, distinguishing between structural adaptations like camouflage, protective coloration, and protective resemblance and behavioral adaptations like migration and traveling in herds. Students also conduct a hands-on inquiry using sow bugs to test hypotheses about how animals are suited to their environments. The lesson connects to key science standards on how organisms' needs and behavior patterns relate to their ecosystems.
Section 1
Organisms Develop Adaptations to Survive
Plants and animals develop structural and behavioral adaptations that help them survive in their environments. These include physical features, behaviors, and defense mechanisms that evolve over time.
Section 2
Animals Use Camouflage to Hide
Animals blend into their surroundings through protective coloration and resemblance. This adaptation helps predators sneak up on prey and helps prey animals hide from danger.
Section 3
Plants Adjust Features for Different Environments
Plants develop specialized adaptations like drip-tip leaves in rainforests, waxy stems in deserts, and specialized stomata in water. These features help plants survive in their specific habitats.
Section 4
Animals Mimic Others for Protection
Some animals copy the appearance of dangerous or unpleasant species. This mimicry tricks predators into avoiding harmless animals, while predator mimicry helps them catch prey more effectively.
Section 5
Animals Change Behaviors with Seasons
Animals migrate to find food or hibernate during harsh weather. These behavioral adaptations help them survive seasonal changes in temperature and food availability throughout the year.
