**Topic: Adaptation** **Objective: WALT Understanding adaptations, types of adaptations and its importance to living things.** **Keywords: environment, behavioural,** ***Adaptations are special features or behaviors that help living things survive in their environments. Every animal and plant you see around you has adaptations that allow it to live, grow, and thrive.*** **What Are Adaptations?** - Adaptations are changes in the physical structure, behavior, or function of an organism that help it survive in its specific environment. - These changes can happen over a long time through a process called evolution. For example, animals that live in cold climates may have thick fur to keep them warm, while those in hot areas might have thin fur or features that help them cool down. **Types of Adaptations.** 1. 2. 3. **Why Are Adaptations Important?** Adaptations are crucial for the survival of species. They allow organisms to: - **Find Food**: Adaptations help animals find and gather food. For example, some birds have strong beaks that can crack open nuts, while others have long beaks to reach nectar from flowers. - **Escape Predators**: Many animals have adaptations to avoid being eaten. For instance, some frogs can change color to blend into their surroundings, making it harder for predators to spot them. - **Reproduce**: Adaptations can also help organisms reproduce successfully. Bright colors in male birds can attract females, increasing their chances of mating. - **Survive Environmental Changes**: As environments change, species with helpful adaptations are more likely to survive. For example, plants in dry areas have deep roots to reach water, allowing them to live even when it's hot and dry. **Examples of Adaptations in Everyday Life** 1. **Cacti**: Cacti have thick, waxy skin that helps them retain water, making them perfect for desert environments where water is scarce. 2. **Polar Bears**: These bears have white fur that helps them blend into the snowy environment, making it easier to hunt seals. 3. **Chameleons**: Chameleons can change their color to match their environment, which helps them hide from predators and sneak up on prey. 4. **Frogs**: Some frogs have sticky pads on their feet that allow them to climb trees and stay safe from ground predators. 5. **Fish**: Many fish have fins and tails that help them swim quickly in water, which is essential for catching food and escaping danger. 1.

Match the correct adaptation to the correct animal picture. **Objective: WALT understand Adaptations in Hot Environments** In our world, some places are very hot, like deserts. Plants and animals that live in these hot environments have special traits, called adaptations, which help them survive. **[Plant Adaptations]** **1. Water Storage** Many plants in hot areas, like cacti, have thick, fleshy stems that store water. This helps them survive long periods without rain. For example, the saguaro cactus can hold a lot of water, allowing it to thrive in the dry desert. **2. Waxy Coating** Plants such as succulents often have a waxy coating on their leaves. This coating reduces water loss, keeping the plant hydrated even when temperatures rise. The wax acts like a shield, preventing moisture from escaping. **3. Deep Roots** Some plants, like mesquite trees, have very deep roots. These roots can reach underground water sources that other plants cannot, allowing them to survive in extreme heat. Deep roots help these trees find moisture even when there is little rain. **[Animal Adaptations]** **Objective WALT: know how Plants and Animals Adapt to Cold Environments** **Cold environments,** like the **Arctic** and **Antarctic**, present unique challenges for plants and animals. To survive in these chilly places, many living things have developed special adaptations. - One of the most noticeable adaptations in cold environments is the **thick fur or blubber** found in animals. For example, polar bears have a thick layer of fat called blubber that **keeps them warm**. - Their fur is also very thick and helps trap heat. Similarly, seals have a layer of blubber that provides insulation against freezing temperatures. - **Plants** also have unique adaptations to survive the cold. For instance, many **plants** in the Arctic have **small, waxy leaves.** This waxy coating helps **prevent water loss** and shields them from harsh winds. Some plants, like mosses, can even survive under a layer of snow. - Another interesting adaptation is **camouflage.** Animals like the Arctic fox change their fur color with the seasons. In winter, their **fur turns white,** helping them **blend** in with **the snow.** - This **camouflage** protects them **from predators** and helps them **sneak up on prey.** **Objective WALT know the amazing Adaptations in Wet Environments** **Wet environments**, like **swamps,** **marshes,** and **rainforests,** are home to many unique plants and animals. These living things have special features, called adaptations, that help them survive in their watery homes. - **Plants** in wet environments often have **wide, flat leaves**. This helps them collect sunlight even when they are surrounded by water. For example, the water lily has large leaves that float on the surface of the water, allowing it to absorb sunlight while its roots are submerged in the mud. - Some plants also have **special roots that can breathe air.** The mangrove tree, found in coastal areas, has roots that stick out of the water, allowing it to take in oxygen. - **Animals** also show amazing adaptations to thrive in wet habitats. Frogs, for instance, **have smooth, moist skin** that helps them **absorb water**. This is important because they live in areas where they can easily dry out. - Some frogs, like the poison dart frog, even use **bright colors** to **warn predators that they are toxic**. - Additionally, animals like the otter have **webbed feet** that make **them excellent swimmers**, allowing them to catch fish and other prey in the water. **Topic: Adaptations of Predators and Prey.** **Objective; WALT understand how Animals Adapt to Survive** In nature, Predators and prey have different adaptations to meet their needs. - **Predators** are animals that hunt other animals for food, while **preys** are animals that are hunted. - **Predators** often have **sharp teeth and claws** to catch their prey. For example, a lion has strong jaws and sharp claws that help it grab hold of its food. - They may also have **keen eyesight** and **good hearing** to **spot** their **prey from a distance**. - Some predators, like the chameleon, can **change color to blend** in with their surroundings. This helps them **sneak up on their prey** without being seen. - Prey animals have adaptations **to avoid being caught**. Many prey animals are **fast runners**, like gazelles, which can quickly escape from predators. - Others, such as rabbits, have **strong hind legs** to **leap away quickly.** - Some animals, like certain species of frogs, are **good at hiding.** They **can blend** into their environment, making it hard for predators to find them. In wet environments, such as swamps or rainforests, adaptations are even more important. - For instance, **fish have fins and gills** that help them **swim and breathe underwater**. - Similarly, some plants, like water lilies, have **wide leaves** that float on the surface, allowing them to **get sunlight** while their roots stay in the mud. **[Think like a scientist. ]** **Circle true or false to answer these questions.** 1. **True or False**: Predators often have sharp teeth and claws to catch their prey. 2. **True or False**: Predators have dull eyesight and good hearing to spot their prey from a distance. 3. **True or False**: Some predators, like the chameleon, can change color to blend in with their surroundings. This helps them sneak up on their prey without being seen. 4. **True or False**: Many prey animals are slow runners, like gazelles, which can quickly escape from predators. 5. **True or False**: Prey animals, such as rabbits, have strong hind legs to leap away quickly. 6. **True or False**: Some animals, like certain species of frogs, are good at hiding and can blend into their environment, making it hard for predators to find them. 7. **True or False**: Fish have fins and gills that help them swim and fight underwater. 8. **True or False**: Water lilies have thin leaves that float on the surface, allowing them to get sunlight
