PART 2 • ACADEMIC VOCABULARY
The Building Blocks of Matter
8th-Grade Scientific Reference
MATTER Materia
Anything with mass and volume (takes up space). All matter is composed of basic particles called atoms.
Key Rule: If it has weight & takes up space, it is matter!
ATOM Átomo
The smallest particle of an element and the fundamental basic building block that makes up all matter.
Key Rule: Cannot be broken down chemically into smaller parts!
ELEMENT Elemento
A pure substance made entirely of only one specific type of atom (such as pure carbon, oxygen, or hydrogen).
Examples: Carbon (C), Oxygen (O), Hydrogen (H)
All non-living and living structures begin with atoms of specific elements! Matter ➔ Elements ➔ Atoms
PART 2 • ACADEMIC VOCABULARY
Bonds, Molecules & Stored Energy
8th-Grade Scientific Reference
CHEMICAL BOND Enlace
The physical attraction connecting two or more atoms together securely in a molecule.
Key Action: Bonds act like chemical glue holding atoms in place.
MOLECULE Molécula
A particle formed when two or more atoms connect by chemical bonds (examples: water H₂O, glucose sugar C₆H₁₂O₆).
Examples: Water (H₂O), Carbon Dioxide (CO₂), Sugar
CHEMICAL ENERGY Energía
The form of energy stored in chemical bonds holding atoms; released when cells break those bonds.
Living Function: Released during cellular respiration to make ATP!
Atoms connect with Bonds ➔ Creates Molecules ➔ Bonds Store Chemical Energy! Essential for All Life

PART 4 • 10 MIN MINI-LESSON
Law of Conservation of Matter
Core Science Principle
Fundamental Law of the Universe:
“Matter cannot be created or destroyed in chemical reactions.”
La materia no se crea ni se destruye en reacciones químicas.
Atoms Only Rearrange
During chemical reactions, bonds break and atoms are simply rearranged to form new molecules. No atoms are lost or gained.
The Sugar & Water Evidence
The combined mass of water and sugar before stirring equals the exact combined mass after stirring them together.
Total Count of Carbon, Hydrogen & Oxygen in Inputs = Total Count of Carbon, Hydrogen & Oxygen in Products

Q5 • NYS June 2018, Q51 Verbatim [1 Pt] Core Life Function
“Explain why organisms break down food molecules during cellular respiration.”
Explica por qué los organismos descomponen moléculas de alimentos en la respiración celular.
Step 1: Chemical Bonds
Food molecules like glucose contain energy stored in their bonds.
Step 2: Breaking Bonds
Cells break down these bonds during respiration to release that energy.
Step 3: Powering Life
The released energy is transferred into ATP to power all cellular life functions.
Packet Response Key: “Organisms break down food molecules to release stored chemical energy needed to carry out life processes and build ATP molecules.”
