Genetic Mutations: Helpful or Harmful?
What Are Genetic Mutations? Genetic mutations are changes in the DNA sequence that can impact traits in various ways. Types of mutations: Point Mutation: A single base change (e.g., sickle cell anemia). Deletion/Insertion: Adding or removing DNA bases. Frameshift...
Cellular Respiration
What Is Cellular Respiration? Cellular respiration is the process by which cells convert food into usable energy, breaking down glucose (sugar) in the presence of oxygen to release energy in the form of ATP (adenosine triphosphate). Three Stages of Cellular...
The Carbon Cycle & Climate Change
What Is the Carbon Cycle? The carbon cycle describes how carbon moves through the Earth’s systems Key Steps in the Carbon Cycle: Photosynthesis: Plants take in carbon dioxide (CO₂) from the air and convert it into oxygen and sugars. Respiration: Animals release CO₂...
Newton’s Laws of Motion: How Objects Move
Newton's First and Second Laws Newton's First and Second Laws explain how objects resist changes in motion and how force affects acceleration. First Law (Law of Inertia): An object will stay at rest or move at a constant speed in a straight line unless acted upon by...
Electricity & Magnetism: How They Work Together
The Science Behind Electricity Electricity is the flow of electrons (tiny particles in atoms) through a conductor like a wire. Example: Batteries and power outlets provide electricity. Current Types: Direct Current (DC): Flows in one direction (e.g., batteries)....
The Invisible World of Microorganisms
What Are Microorganisms? Microorganisms are tiny living organisms visible only under a microscope. Types include: Bacteria: Single-celled organisms found everywhere (e.g., in soil, water, and our bodies). Viruses: Non-living particles that infect living cells to...
Rock Cycle
Types of Rocks There are three main rock types, with rocks changing between each type over millions of years. Igneous rocks are formed from the cooling of molten rock (magma & lava) Magma cools underground → forms intrusive igneous rocks (e.g., granite). Lava...
The Big Bang Theory
The Big Bang – What Happened? 13.8 Billion Years Ago: The universe began as a tiny, hot, and dense point called a singularity. This singularity suddenly expanded in an event called the Big Bang, releasing enormous energy. In the first fractions of a second, the...
