Natural Sciences - Term 4 - Week 7

Plants and animals are essential parts of our ecosystem. Plants produce oxygen and food through photosynthesis, while animals depend on plants for food and shelter. In this lesson, we will explore different types of plants, such as trees, flowers, and grasses, and various animals, including mammals, birds, and insects. Understanding how these organisms interact helps us appreciate the balance of nature.

Let’s look at a few examples. A sunflower is a type of plant that grows tall and has bright yellow petals. It attracts bees, which are animals that help pollinate flowers. Another example is the oak tree, which provides shelter for many animals, such as squirrels and birds. By observing these examples, we can see how plants and animals rely on each other for survival.

In groups, discuss the plants and animals you see in your neighborhood or schoolyard. What types of plants grow there? What animals do you notice? Share your observations with the class. As you talk, use the vocabulary words we’ve learned, such as 'habitat,' 'photosynthesis,' and 'ecosystem.' This will help reinforce your understanding and improve your ability to explain these concepts.

For your mini-project, create a poster that showcases a specific plant and an animal that interacts with it. Include pictures, labels, and descriptions of how they depend on each other. For example, you could choose a bee and a flower, explaining how the bee collects nectar while helping the flower to reproduce. Be prepared to present your poster to the class and explain your findings.

• Respiration
• Photosynthesis
• Digestion
• Pollination

Answer: Photosynthesis

Photosynthesis is the process by which plants use sunlight to convert carbon dioxide and water into glucose and oxygen.

• Eagle
• Shark
• Elephant
• Frog

Answer: Elephant

Elephants are mammals because they are warm-blooded, have hair, and nurse their young with milk.

Answer: Animals depend on plants for food.

Many animals eat plants directly, while others eat animals that have eaten plants.

• A type of plant
• A place where an organism lives
• A food chain
• A type of animal

Answer: A place where an organism lives

A habitat is the natural environment in which an organism lives and thrives.

Answer: A bee and a flower.

Bees collect nectar from flowers, which helps the flowers to reproduce.

• Fern
• Rose
• Goldfish
• Cactus

Answer: Goldfish

Goldfish are animals, while ferns, roses, and cacti are all types of plants.

Answer: It helps maintain the balance of the ecosystem.

Interactions between plants and animals ensure that both groups can survive and thrive in their environment.

• Providing shelter
