Scientists are searching for life on planets outside our solar system, called exoplanets.
Science, Earth & Space Science
The solar system is a large neighborhood in space with a star, planets, and moons.
Ecosystems are communities where living and non-living things interact, cycling matter and transferring energy.
Mechanical waves need a medium to travel, like air or water, while electromagnetic waves can travel through empty space.
Gravity is a force that pulls objects together, keeping planets in orbit around the Sun.
The Arctic Ocean is a cold environment that is home to many living things, from tiny algae to huge whales.
Magnetism is a force where objects attract or repel each other through a magnetic field.
Sound is a vibration that moves as a wave through air, water, or solids.
Stars have life cycles that last millions or billions of years, which astronomers study using tools like the Hertzsprung-Russell diagram.
Gravity is a force that pulls things together and shapes galaxies and solar systems.
To survive winter, some animals migrate to warmer areas where food is easier to find, while others hibernate to conserve energy.

Your immune system is a complex network that protects you from germs and helps you heal from injuries.
Fireflies use light to attract mates, with males flashing unique patterns to signal females.
At high altitudes, the human body struggles due to less oxygen in the air.
Adaptations are traits that help animals survive and reproduce in their environment.
Penicillin was discovered in 1928 and, by 1950, scientists developed a way to mass produce antibiotics to fight deadly infections.
The human brain is a complex organ that controls everything we do, think, and feel.
Biologists classify living things based on shared characteristics to understand relationships between life forms.
Cells are the basic building blocks of all living things.
The cell membrane protects the cell and controls what goes in and out.
The nervous and endocrine systems are the body's communication networks.
A lab is studying a protein called ACTN3 to see if it affects running ability.
Oxygen is usually a gas, but it can become a liquid if it gets cold enough.
Science, Chemistry
Matter is made of atoms and molecules and exists mainly as solids, liquids, or gases.
Naming compounds is like learning a new language, but it can be simple if you follow the rules.
Nuclear fission is when an atom's nucleus splits, releasing a lot of energy.
Elements are pure substances that can't be broken down, like gold or carbon.
Physical changes alter the appearance of a substance without changing its chemical composition.
Physical changes alter a substance's appearance without creating a new substance.
The periodic table organizes elements by their atomic number and properties.
Gases can be identified by their unique properties, like color and smell, and how they react with other substances.
Decantation is a way to separate mixtures by letting heavier parts sink and pouring off the lighter parts.
Science, Science, Chemistry
Atoms connect through chemical bonds, like ionic bonds, where ions play a key role.
Atomic bombs are strong bombs that use nuclear reactions to make big explosions.
