• Our planet is rich and abundant in natural resources
• Natural resources play an important role in our survival
• The location of a country is related to its natural resources
• Natural resources in the Philippines

  • Water resources
  • Fertile soil
  • Diverse plants and animals
  • Precious metal deposits
• Water


  Makes up 71% of our planet Earth, exists in different forms like lakes, rivers, streams, and is essential to life
• Soil


  Plays a vital role in the life of plants, provides water and nutrients, home to many burrowing animals and crawling insects, needed for food production
• Rocks, stones, gravel, sand


  Used to make roads, buildings, monuments, and art objects
• Fossil fuels


  Include coal, petroleum, and natural gas, used to produce energy
• Alternative energy sources


  • Solar energy
  • Wind energy
  • Hydropower
  • Geothermal energy
• Natural resources play a vital role in our survival, but they are not endless in supply
• Lack of environmental awareness, human greed, and carelessness are threatening natural resources to depletion and extinction
• Sustainability of natural resources

  Conserving them to make them last for future generations
• Ways to conserve natural resources

  • Reduce
  • Reuse
  • Recycle
  • Turn off faucets when not in use
  • Stop dumping waste in water bodies
  • Unplug electric appliances when not in use
  • Plant more trees
  • Reduce use of fertilizers and chemicals
  • Practice crop rotation and vermicomposting
  • Prefer walking for short distances over using vehicles
  • Say no to plastic
• Natural resources


  Materials created and gathered from nature that humans use to survive and satisfy their needs
• Examples of natural resources


  • Plants
  • Animals
  • Rocks
  • Minerals
  • Bodies of water
  • Sunlight
  • Wind
• Man-made resources


  Things created from natural resources that provide utility and value to our lives
• Man-made resources


  • Chairs
  • Tables
  • Roads
  • Buildings
  • Light
• Types of natural resources

  • Renewable
  • Non-renewable
• Renewable resources


  Resources that can grow again or be replaced after being consumed, can be generated quickly, and are found in large quantities
• Renewable resources can be depleted


  If not properly managed or conserved
• Non-renewable resources


  Resources that cannot be replaced once consumed, found in nature in small or limited quantities, and take long periods of time to generate
• Both renewable and non-renewable resources must be used wisely and properly
• It has taken many thousands and millions of years to develop and accumulate these natural resources
• If natural resources are not conserved, there will not be enough for life in the future and for future generations
• Who is the teacher in the video from Ilocos Norte?

  Teacher MJ
• What is the main topic of discussion for the week?

  The relationship between the amount of force applied and the mass of the object to the amount of change in the object's motion
• What is the purpose of the quick drill at the beginning of the lesson?

  • To test students' knowledge about forces
  • To engage students before the main discussion
• What is the correct answer regarding the presence of force when pulling an object?

  Yes, force is applied when you pull an object
• Is force present when weaving?

  Yes, force is applied when weaving
• Can force be present even if an object is not in motion?

  Yes, force is still present even if an object is not in motion
• What is displacement?


  The gap between the initial position and the final position of an object
• How is velocity defined?

  Velocity is the speed at which something moves in one direction
• What is acceleration?


  Acceleration is the time rate of change of the velocity of an object
• What is the definition of force?

  Force is generally defined as the push and pull applied to an object
• What happens to a closed door without force applied?

  The door will remain closed unless a force acts on it
• How does kicking a soccer ball relate to force?

  Kicking a ball requires force and the strength of the kick affects the ball's speed
• What is the relationship between the amount of force applied and the velocity of an object?

  The stronger the force applied, the faster the object moves
• What is the effect of pushing a toy car to the right?

  The toy car will move in the same direction as the force applied
• How can you stop a moving toy car?

  You have to apply a force opposite to the direction it is going
• What is the effect of applying an additional push to a moving toy car?

  The toy car will go faster in the same direction
