Natural Sciences - Term 1 - Week 3

Plants and animals are essential components of our ecosystem. Plants are living organisms that typically produce their own food through photosynthesis, while animals are organisms that consume other living things for energy. In this lesson, we will explore the unique characteristics of both groups, such as their structures, functions, and roles in the environment.

For example, consider a sunflower. It has a tall stem, broad leaves, and bright yellow petals. The stem supports the plant and transports water and nutrients from the roots. The leaves are where photosynthesis occurs, and the petals attract pollinators. Understanding these characteristics helps us appreciate how plants grow and thrive.

Let's have a class discussion about different animals. Think about your favorite animal and describe its characteristics. For instance, if you choose a lion, you might mention its mane, sharp teeth, and social behavior in prides. As we share, let's use vocabulary words like habitat, diet, and adaptation to enhance our descriptions.

For your mini-project, choose either a plant or an animal and create a profile. Include its name, habitat, diet, and interesting facts. You can draw a picture or find one online to include in your profile. Be prepared to present your profile to the class, explaining why you chose that particular plant or animal and what you learned about it.

• Photosynthesis
• Respiration
• Digestion
• Transpiration

Answer: Photosynthesis

Photosynthesis is the process by which plants convert sunlight into energy, using carbon dioxide and water.

• They can photosynthesize
• They consume food
• They can move
• They have specialized senses

Answer: They can photosynthesize

Animals do not have the ability to photosynthesize; they rely on consuming other organisms for energy.

Answer: Thick leaves or deep roots.

Thick leaves help reduce water loss, while deep roots can access underground water sources.

• Support the plant
• Store nutrients
• Conduct photosynthesis
• Attract pollinators

Answer: Conduct photosynthesis

Leaves are primarily responsible for conducting photosynthesis, where sunlight is converted into energy.

Answer: Animals may develop camouflage to blend in with their surroundings.

Camouflage helps animals avoid predators and increases their chances of survival.

• Lion
• Elephant
• Wolf
• Eagle

Answer: Elephant

Elephants are herbivores, meaning they primarily eat plants.

• Ecosystem
• Habitat
• Biome
• Niche

Answer: Habitat

A habitat is the natural environment where a species lives and thrives.
