Mini Lesson

An adaptation is a physical feature or behavior that helps a living thing survive in its environment. Adaptations develop over many generations through a process called natural selection — organisms with useful traits are more likely to survive and pass those traits on.

Plant Adaptations

  • Thick waxy leaves — desert plants like aloe lose less water through a waxy coating; cacti store water in thick stems.
  • Deep roots — grassland plants reach underground water supplies.
  • Broad leaves — plants on the shaded rainforest floor capture limited sunlight filtering through the canopy.
  • Thorns — sharp spines deter herbivores from eating the plant.

Animal Adaptations

  • Camouflage — a chameleon blends into its surroundings to hide from predators.
  • Thick fur — an Arctic fox stays warm in freezing temperatures.
  • Sharp claws — an eagle grips and catches prey effectively.
  • Long neck — a giraffe reaches leaves high up in tall trees.

How Adaptations Develop

  • Adaptations develop over many generations, not in a single lifetime.
  • Natural selection: organisms with helpful traits survive longer and reproduce more.
  • Over time, the useful trait becomes common in the population.

Words to know

adaptation

A physical feature or behavior that helps a living thing survive in its environment.

natural selection

💡

Tip: think about the environment first, then ask — what feature would help an organism survive there? That feature is an adaptation.

Guided Practice

Pick a word from the Trace menu and look carefully — after 3 seconds the ghost letters fade and you write the word from memory. Tap 🔁 Show again to bring the model back, or 🔍 Bigger for a fullscreen practice canvas.

Tracing Pad

Tip: Say each word aloud as you copy it.

Now type any 3 different words from the Trace menu above. Look back if you need to — this is typing practice, not a memory test.
