Science

• Gravity


  Attracts objects with mass towards each other, fundamental force of nature
• Friction


  Opposes motion between surfaces in contact, static and kinetic types
• Magnetic Force


  Acts between magnetic objects or fields, strength depends on mass and distance
• Gene


  Unit of heredity, carries information from one generation to the next, DNA sequence
• DNA


  Molecule containing genetic instructions for development and function
• Genetic Code


  Set of rules translating DNA sequence into amino acid sequence in protein
• Exothermic Reaction


  Releases heat energy, often with temperature increase
• Chemical Reaction


  Process converting reactants into products through breaking and forming of chemical bonds
• Endothermic Reaction

• An element is a substance that cannot be broken down into simpler substances by ordinary means.
• A chemical reaction is when two or more substances react to form one or more new substances.
• To calculate the product, we need to know both factors.
• A factor is one of the numbers that can be used to find another number by multiplying them together.
• To calculate the product, we need to know both factors.
• A factor is one of the numbers that can be used to find another number by multiplying them together.
• The product of two numbers is the result when they are multiplied together.
• The formula for finding the product of three numbers is A x B x C = P (product).
• The periodic table organizes all known elements based on their atomic number (number of protons) and electron configuration.
• The periodic table organizes all known elements based on their atomic number (number of protons) and electron configuration.
• The periodic table organizes all known elements based on their atomic number (number of protons) and electron configuration.
• The number of atoms on the left side must equal the number of atoms on the right side.
• The number of atoms on the left side must equal the number of atoms on the right side.
• The number of atoms on the left side must equal the number of atoms on the right side.
• The Law of Conservation of Mass states that matter can neither be created nor destroyed, only changed from one form to another.
• Atoms are the smallest particles of an element that can exist independently.
• A compound is a substance made up of two or more elements chemically combined together.
• What is the definition of force?


  A force is a push or pull that can change an object's motion.
• Inheritance

  The passing of DNA traits or characteristics from parents to offspring through genes
• Gene

  A unit of heredity passed from parents to offspring, comprising a sequence of DNA that carries information to create a specific trait or characteristic
• Sex Cells (Gametes)

  Specialized cells responsible for reproduction, containing half the number of chromosomes as the parent cell (sperm or egg cells)
• Electromagnetic Spectrum

  A range of electromagnetic energies, including radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays
• Magnetic Domains

  Small regions within a magnet where the magnetic domains are aligned, creating a strong magnetic field
