Prevention of STI’s, HIV\AIDS.
- Biodegradable Materials:
- These are materials that can be broken down by bacteria or other living organisms over time.
- Example: Food scraps, paper, and certain types of plastics are biodegradable.
- 🌱 Biodegradable materials help reduce pollution and protect the environment.
- Chemical Symbols:
- Chemical symbols are shorthand ways of representing elements.
- Example: “Cu” is the chemical symbol for copper.
- 🧪 Chemical symbols help scientists communicate about elements in a concise way.
- Characteristics of Living Things:
- Living things have certain traits or characteristics that set them apart from non-living things.
- Example: Growth, reproduction, and movement are characteristics of living things.
- 🌱 Understanding these characteristics helps us classify and understand living organisms better.
- Organ Systems:
- The human body is made up of different organs that work together in systems to perform various functions.
- Example: The heart pumps blood to every part of the body in the circulatory system.
- ❤️ Learning about organ systems helps us understand how our bodies function.
- HIV/AIDS Transmission:
- HIV/AIDS is a disease caused by the human immunodeficiency virus (HIV).
- Example: HIV/AIDS can be transmitted through unprotected sex, sharing needles, or from an infected mother to her baby during childbirth or breastfeeding.
- 🦠 Understanding how HIV/AIDS is transmitted helps prevent its spread and protect our health.
- Breastfeeding:
- Breastfeeding is a way of feeding babies with breast milk directly from the mother’s breast.
- Example: Mammals, including humans, breastfeed their young to provide them with essential nutrients and antibodies.
- 🍼 Breastfeeding is important for the health and development of newborn babies.
- Non-living Things:
- Non-living things are objects or substances that do not exhibit characteristics of life.
- Example: Rocks, water, and air are examples of non-living things.
- ⚡️ Non-living things do not grow, reproduce, or respond to stimuli like living organisms do.
- Materials for Electrical Cables:
- Electrical cables are made from materials that can conduct electricity effectively.
- Example: Copper is commonly used for making electrical cables because it is a good conductor of electricity.
- 💡 Using the right materials ensures that electrical cables function safely and efficiently.
- Causes of AIDS:
- AIDS is caused by the human immunodeficiency virus (HIV), which attacks the body’s immune system.
- Example: HIV can be transmitted through unprotected sex, sharing needles, or from an infected mother to her baby during childbirth or breastfeeding.
- 🦠 Understanding the causes of AIDS helps us prevent its transmission and support those affected by the disease.
- Feathered Animals:
- Some animals have feathers, which are specialized structures covering their bodies.
- Example: Birds are well-known for having feathers, which help them fly, regulate body temperature, and attract mates.
- 🐦 Feathers are unique to birds and play important roles in their survival and behavior.

Class Activity Discussion :
- What is a biodegradable material?
- Biodegradable materials are things that can break down naturally over time, like food scraps and some types of plastics.
- What does “Cu” stand for?
- “Cu” is the chemical symbol for copper, a shiny metal often used in electrical wiring and pipes.
- What are the characteristics of living things?
- Living things can grow, reproduce, and respond to their environment. Movement is also a characteristic of many living things.
- Which organ pumps blood to every part of the body?
- The heart is the organ responsible for pumping blood throughout the body, delivering oxygen and nutrients to cells.
- How is HIV/AIDS transmitted?
- HIV/AIDS can be transmitted through unprotected sex, sharing needles, or from an infected mother to her baby during childbirth or breastfeeding.
- Is breastfeeding a characteristic of mammals?
- Yes, breastfeeding is a characteristic behavior of mammals, including humans. It provides essential nutrients and antibodies to newborns.
- What are non-living things?
- Non-living things are objects or substances that do not possess life, like rocks, water, and air.
- What is used for making electrical cables?
- Copper is commonly used for making electrical cables because it is a good conductor of electricity.
- What causes AIDS?
- AIDS is caused by the human immunodeficiency virus (HIV), which weakens the body’s immune system and makes it vulnerable to infections.
- Which animals have feathers?
- Birds are the animals known for having feathers. Feathers help them fly, regulate body temperature, and attract mates.
- What defines a metal?
- Metals are materials that are typically hard, shiny, and can conduct heat and electricity. Copper and iron are examples of metals.
- What material is used for making plates?
- Plates are often made from materials like ceramic, glass, or plastic, depending on their intended use.
- What is stored energy in food called?
- The energy stored in food is called chemical energy, which our bodies use to fuel activities and maintain bodily functions.
- How do organs work together in the human body?
- Organs work together in systems to perform specific functions, such as the circulatory system, which includes the heart, blood vessels, and blood.
- Can HIV/AIDS be transmitted through sharing towels?
- No, HIV/AIDS cannot be transmitted through sharing towels or casual contact. It is mainly spread through bodily fluids like blood, semen, and vaginal fluids.
