General Science Quiz

How materials change size due to temperature changes.

The movement of energy from one place or object to another.

A path for electricity to flow through.

The path a comet takes around the sun.

How forces cause objects to move or fall.

The total length covered by a car's movement in a given timeframe, when traveling at a constant speed.

A solar eclipse happens when the Moon passes between the Sun and Earth, casting a shadow on Earth. A lunar eclipse occurs when the Earth passes between the Sun and the Moon, casting a shadow on the Moon.

Information gathered through direct sensing of phenomena using the five senses (sight, hearing, touch, taste, smell).

Wool is a poor conductor of heat, meaning it doesn't easily transfer heat. This makes it excellent for keeping warm in cold weather.

When heated, metals increase in size because the atoms move further apart. Conversely, they contract (get smaller) when cooled.

This measures the volume of a liquid by determining the amount it takes up within the cylinder.

Density is the mass of a substance per unit volume. A denser substance has more mass packed into the same space.

The speed of a rocket at a certain time after it's launched, based on the provided model rocket launch data.

A relationship between two different species where both benefit.

The curved path an object takes when thrown or launched, influenced by gravity.

The overall force acting on an object, considering all forces and their directions.

A scale used to measure the relative scratch resistance of minerals.

The total energy in an isolated system remains constant, though it can change forms.

The product of an object's mass and its velocity, representing its motion.

A principle describing the conservation of mass in fluid flow, stating that the mass flow rate remains constant.

A state where the electric field inside a conductor is zero, indicating no net charge movement.

Simple cells lacking a nucleus and membrane-bound organelles, such as bacteria and archaea.

Complex cells with a nucleus and membrane-bound organelles, found in plants, animals, fungi, and protists.

Cellular structures responsible for protein synthesis, present in both prokaryotic and eukaryotic cells.

A coenzyme that carries electrons in cellular respiration, accepting electrons to become NADH.

A process where cells break down glucose to produce ATP (energy) using oxygen.

The process by which plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

The second stage of photosynthesis where carbon dioxide is converted into sugar using the energy produced in the light reactions.

The first stage of photosynthesis where light energy is captured and converted into chemical energy (ATP and NADPH).

The process by which cells break down glucose to release energy in the form of ATP.

A group of single-celled organisms that are similar to bacteria but have some unique characteristics, such as living in extreme environments.

A chemical reaction that removes a water molecule from two molecules, joining them together.

A group of subjects that do not receive the treatment being studied, used as a baseline for comparison.

States that the entropy of a closed system always increases over time, meaning that energy is dispersed and becomes less useful.
