Basic Science Vocabulary

Learn the English words used in science!

📖 Let’s Learn Science Words!

Science is the study of the world around us — how things work, why things happen, and what things are made of. Every scientist uses special vocabulary to describe their discoveries!

Learning science words helps you understand your EVS/Science textbook, ask smart questions, and describe how the world works. These words connect English to what you learn in Science class!

💡 The Rule

Science words describe things in nature (planet, seed, leaf), forces and energy (gravity, magnet, solar), and processes (evaporation, germination, photosynthesis). Group them by topic!

🎯 Key Concept

🪐 Planet = a large body orbiting a star
🧲 Magnet = attracts iron and steel
🌱 Germination = when a seed starts growing
💧 Evaporation = water turning into vapour

📋 Science Word Categories

🧲
Forces

Gravity, magnet, friction, push, pull

🌱
Plants

Seed, root, stem, leaf, flower, fruit

💧

Space & Earth

planet
a large body that orbits a star
“Earth is the third planet from the Sun.”
solar system
the Sun and everything orbiting it
“Our solar system has 8 planets.”
orbit
the path a planet takes around the Sun
“Earth’s orbit around the Sun takes 365 days.”
star
a ball of hot gas that shines in space
“The Sun is the nearest star to Earth.”
gravity
the force that pulls things down
“Gravity keeps us on the ground.”

Energy & Forces

energy
the ability to do work or make things happen
“The Sun gives us light and heat energy.”
solar
related to the Sun
“Solar panels convert sunlight to electricity.”
magnet
attracts iron and steel objects
“A magnet sticks to the fridge door.”
friction
force that slows down moving objects
“Friction makes the ball stop rolling.”
electricity
form of energy for lights and machines
“Electricity powers our TV and computer.”
🌱

Plants & Growth

seed
the tiny part from which a plant grows
“Plant the seed in soil and water it.”
root
the part of plant underground
“Roots absorb water from the soil.”
stem
the main body of the plant
“The stem carries water from roots to leaves.”
leaf
the flat green part that makes food
“Leaves make food using sunlight.”
germination
when a seed starts to sprout and grow
“Germination needs water, warmth, and air.”
💧

Water Cycle & Weather

evaporation
liquid water turning into water vapour
“Heat causes evaporation of water.”
condensation
water vapour turning back into liquid
“Condensation forms clouds in the sky.”
precipitation
water falling from clouds as rain/snow
“Rain is a type of precipitation.”
temperature
how hot or cold something is
“The temperature today is 35 degrees.”
thermometer
instrument to measure temperature
“The doctor used a thermometer to check my fever.”

1

Earth is a planet that orbits the Sun.

2

Gravity is the force that pulls everything down.

3

A magnet can attract objects made of iron.

4

Roots absorb water and the stem carries it to the leaves.

5

Evaporation turns water into vapour, forming clouds.

6

Solar energy from the Sun can make electricity.

🧠

Memory Trick

Remember the Water Cycle: Evaporation (water → vapour) → Condensation (vapour → clouds) → Precipitation (clouds → rain). E-C-P! Up, form, fall!

Fun Facts

India’s space agency ISRO successfully sent a spacecraft to Mars (Mangalyaan) in 2014 — on its very first try! And it cost less than making a Hollywood movie!

The word “science” comes from the Latin word “scientia” meaning “knowledge”. A scientist is simply a person who seeks knowledge!

🧠 Tips for Parents

🔬

Kitchen Science

Do simple experiments at home: magnet test (what sticks?), germination (grow a bean in cotton). Hands-on learning!

🪐

Stargazing

Look at the night sky together. Point out the Moon, planets, and stars. Connect to vocabulary: orbit, gravity, solar system.
