Adaptations In Animals: Structural And Behavioral Adaptations

Introduction

• Focus on animal adaptations as per Singapore Primary 6 Science syllabus.
• Two main types of adaptations:
  • Structural Adaptations
  • Behavioural Adaptations

Adaptations

• Adaptations refer to changes that help an organism survive and thrive in its environment.
• Aid in coping with physical factors, obtaining resources, protection from predators, and reproduction.
• Two main types:
  • Structural Adaptations: Physical characteristics aiding survival.
  • Behavioural Adaptations: Ways of behaving that enhance survival.

Structural Adaptations

• Involve specific physical features that enhance survival.
• Examples:
  • Hummingbird: Long beak to reach nectar.
  • Tree Lizard: Long tail for balance.
  • Giraffe: Long neck to reach high vegetation.
  • Duck: Webbed feet for efficient swimming.
• Include features like camouflage, speed, and blending into surroundings to avoid predators.

Behavioural Adaptations

• Changes in behavior that aid in survival.
• Examples:
  • Migration: Birds migrating to warmer climates during winter.
  • Hibernation: Bears conserving energy in winter.
  • Social Behaviour: Primates forming groups for predator protection.

Conclusion

• Adaptations are crucial for survival and interaction with the environment.
• Important for students to understand these as part of the PSLE science syllabus.

Assessment Questions

Question 1

• Context: Identifying which bird can feed from a flower based on beak shape.
• Answer: Bird with long narrow beak.

Question 2

• Context: Fly mimicking a bee to avoid predators.
• Answer: Mimicry tricks predators into thinking it is a harmful bee.

Question 3

• Context: Determining which animal covering is better for cold environments.
• Answer: Covering with highest temperature retention (R) is best for cold environments.

Question 4

• Context: Frog adaptations unrelated to survival.
• Answer: Laying eggs instead of live birth is not directly an adaptation for survival.

Question 5

• Context: Bird folding wings for streamlined shape when diving.
• Answer: Streamlining reduces water resistance, aiding in catching prey.
