📚 The 10 Essential Science Words
Everyday phenomena explained in clear, natural English.
Light and Air
| Word | Simple Meaning | Common Collocations | Word Forms | Everyday Example | 💡 Memory Tip |
|---|---|---|---|---|---|
| atmosphere | The layer of gases surrounding Earth or another planet. | Earth's atmosphere, upper atmosphere | atmospheric (adj) | Meteors burn up as they enter Earth's atmosphere. | Think of a "sphere" of air wrapped around the globe like a coat. |
| particle | A tiny piece of matter such as dust, smoke, or water droplets. | dust particle, tiny particles | – | You can see dust particles floating across a beam of sunlight. | Sounds like "part" — just a microscopic part of a bigger thing. |
| scatter | To spread or throw light, objects, or energy in many different directions. | scatter light, scatter in all directions | – | Air molecules scatter blue sunlight more than red sunlight, turning the sky blue. | Imagine dropping a box of beads that roll everywhere across the floor. |
| absorb | To soak up liquid, take in heat, or hold energy instead of letting it bounce off. | absorb heat, absorb moisture | absorption (n) | Black shirts feel warmer on sunny days because they absorb light and heat. | Think of a sponge sucking in water until nothing leaks out. |
How Light Behaves
| Word | Simple Meaning | Common Collocations | Word Forms | Everyday Example | 💡 Memory Tip |
|---|---|---|---|---|---|
| reflect | To bounce light, heat, or sound off a surface without absorbing it. | reflect sunlight, reflect off the water | reflection (n) | Calm lake water can reflect mountain peaks like a giant mirror. | Prefix "re-" (back) + "flect" (bend): bending rays right back at you. |
| visible | Able to be seen clearly by the human eye. | clearly visible, barely visible | visibility (n), visibly (adv) | Stars are more easily visible when streetlights are turned off. | Root "vis-" relates to vision; "-ible" means able to be seen. |
| faint | Weak, dim, or barely perceptible to the senses. | faint glow, faint sound | faintly (adv) | We noticed a faint green glow from fireflies in the tall grass. | A faint signal is like a whisper: you must pay close attention to catch it. |
Scientific Thinking
| Word | Simple Meaning | Common Collocations | Word Forms | Everyday Example | 💡 Memory Tip |
|---|---|---|---|---|---|
| observe | To watch something carefully and record changes over time. | observe behavior, carefully observe | observation (n), observer (n) | Students observe how ice melts under different lamp colors. | More than casual looking: you serve as an active watcher taking notes. |
| explanation | A clear statement or reason that makes a fact understandable. | scientific explanation, plausible explanation | explain (v) | The textbook gives a simple explanation of why puddles evaporate. | To explain is to make "plain" and easy to see. |
| evidence | Facts, signs, or measurements proving whether a statement is true. | clear evidence, gather evidence | evident (adj) | Tree rings provide evidence of wet and dry seasons centuries ago. | "Evidence" makes the truth self-"evident" to everyone. |
