What is Energy?
Have you ever wondered why a ball rolls, why a lamp glows, or why your
tummy growls when you're hungry?
The answer is energy! Energy is the power that makes
things move, glow, grow, and heat up. You can't see
energy, but you can always see what it does! ๐
Here's the most amazing thing โ energy is never destroyed.
It just changes from one form into another. Let's discover how! โกโจ
Energy โ The Power to Do Things!
Energy is what makes everything happen in the world!
When you jump, you use energy. When toast pops out of the toaster,
that's energy. When a bird sings, that's energy too! ๐ฆ
๐ Kinetic energy is energy of movement โ like a
rolling ball or a running cheetah!
๐ Potential energy is stored energy โ like a ball
sitting at the top of a slide, ready to roll!
๐ก๏ธ Heat energy makes things warm โ like the Sun
heating your face on a summer day!
Fun fact: Even when you sleep, your body uses energy
to keep your heart beating and lungs breathing! You are never
really "switched off"! ๐ดโก
Electricity โ The Magic Power!
Electricity is the flow of tiny, tiny particles called
electrons through a wire โ like water flowing
through a pipe! We cannot see electrons but we can see what they do! ๐ก
๐ก Lights glow because electricity flows through them!
๐ฑ Your phone and tablet run on electricity!
โ๏ธ The refrigerator that keeps your food cold
uses electricity!
Fun fact: Lightning is a giant
spark of electricity in the sky! One lightning bolt is hotter than
the surface of the Sun โ about 30,000ยฐC! โ๏ธ๐ฉ๏ธ
Renewable Energy โ Power from Nature!
Some energy comes from sources that never run out
because nature keeps making more! We call these
renewable energy sources! ๐
โ๏ธ Solar energy comes from sunlight โ solar panels
on rooftops capture it!
๐จ Wind energy spins giant wind turbines to make
electricity!
๐ง Hydroelectric energy uses flowing water in rivers
and dams to generate power!
Fun fact: Coal and oil are non-renewable
โ they took millions of years to form and are running out fast!
That's why renewable energy is so important! ๐ฟ
Batteries โ Energy in a Little Box!
A battery is like a tiny energy storage box! It
stores chemical energy inside, and when you connect
it to something, it releases that energy as electricity! ๐ช
๐ฆ Small batteries power your torch and toys!
๐ Big batteries power electric cars โ some can drive
over 500 km on a single charge!
๐ Dams are like giant batteries โ they store
potential energy in water until it's needed!
Fun fact: Your body is like a battery too! The
food you eat is your fuel. Eating a banana gives
you enough energy to walk for about 30 minutes! ๐๐ช
Every time you eat food, you are using ancient solar energy! ๐ Plants capture sunlight through photosynthesis and store it as energy. When you eat a plant โ or eat an animal that ate plants โ that energy goes inside you! Then your muscles use it to run, jump, and play. The Sun is the ultimate source of almost all energy on Earth. We are all powered by sunshine! โ๏ธ๐ฑ๐
