What is the electrical charge of a single electron?
Negative (-1)
This is the primary gas that humans inhale from the air to survive, which is then carried by red blood cells to all parts of the body.
Oxygen
This is the outermost, rocky layer of the Earth that we live on, which is broken up into tectonic plates.
The Crust
This is the invisible pulling force that keeps our feet on the ground and causes dropped objects to fall toward the Earth.
Gravity
This popular block-building game allows players to explore infinite worlds, mine materials, and escape Creepers.
Minecraft
Which subatomic particles are found grouped together in the central nucleus of an atom?
Protons and Neutrons
These disc-shaped blood cells use a protein called hemoglobin to carry oxygen from your lungs to the rest of your body.
Red blood cells
This gas makes up roughly 78% of Earth's atmosphere, making it the most abundant gas on the planet.
Nitrogen
This type of material, like copper or aluminum, allows electricity or heat to easily flow through it.
A Conductor
This mega-pop star broke records worldwide with her massive, record-shattering "Eras Tour."

How do the particles in a gas behave compared to the particles in a solid?
Gas particles move quickly/rapidly and spread far apart.
This is the largest organ of the human body, serving as a primary defense against pathogens and regulating temperature.
Despite being hot enough to melt, this innermost layer of the Earth remains a solid ball due to the immense pressure squeezing it.
Inner core
This stored energy is what an object has due to its height above the ground, before it starts falling.
Gravitational Potential Energy
This Pixar sequel, released in 2024, became the highest-grossing animated movie of all time by introducing new teenage emotions like Anxiety and Envy.
Inside Out 2
An uncharged (neutral) atom has 8 protons in its nucleus. How many electrons does this neutral atom normally contain?
8 Protons
This tough, flexible tissue acts as a cushion between bones at a joint to prevent them from rubbing together.
Cartilage
This thick, semi-solid layer sits directly beneath the crust and makes up the bulk of Earth's total volume.
The mantle
This is the scientific term for when light bounces off a smooth surface, like a mirror, allowing you to see your image.
Reflection
This is the only country in the world that is also home to the ancient hidden city of Machu Picchu, high up in the Andes Mountains.
Peru
What term describes the phase change when a solid turns directly into a gas without passing through the liquid state?
Sublimation
These tiny, microscopic air sacs in the lungs are wrapped in blood vessels and are the exact location where oxygen enters your blood and carbon dioxide leaves it.
Alveoli
This is the scientific term for the giant pieces of the Earth's crust and upper mantle that slowly move and crash into each other, creating earthquakes and mountains.
Tectonic plates
This basic physics rule states that energy cannot be created or destroyed, only transformed from one type to another.
Law of Conservation of Energy
Garnering over 17 billion plays, this incredibly repetitive, aquatic children's song and dance video is officially the most-viewed YouTube video of all time.
