Biology
This is considered to be the smallest unit of life.
What is a cell?
This state of matter has no fixed shape but has a definite volume.
What is an liquid?
This force keeps us on the ground and makes apples fall from trees.
What is gravity?
The gas required for photosynthesis to occur.
What is Carbon Dioxide (CO2)?
This scientist developed the theory of gravity after watching an apple fall from a tree.
Who is Isaac Newton?
This body system allows for gases, nutrients, and other materials to be transported through the body.
What is the circulatory system?
This element, with the symbol C, is the basis of all living things.
What is carbon?
This force opposes motion and creates heat.
What is friction?
This layer of Earth’s atmosphere protects us from harmful ultraviolet radiation.
What is the ozone layer?
This French mathematician and inventor created an early mechanical calculator and has a unit of pressure named after him.
Who is Blaise Pascal?
This molecule carries genetic information in all living things.
What is DNA?
This is a cloudy mixture in which droplets or tiny pieces of one substance are held within another substance.
What is a suspension?
This phenomenon causes light to bend when it passes from air into water.
What is refraction?
This process describes the gradual increase in Earth’s average temperature due to greenhouse gases.
What is global warming?
This pioneering scientist discovered radioactivity and won two Nobel Prizes in Physics and Chemistry.
Who is Marie Curie?
This process in plants releases water vapor through the stomata in their leaves.
What is transpiration?
This type of acid is found in your stomach and helps digest food.
What is hydrochloric acid?
This type of lens curves outward and makes light rays spread apart.
What is a convex lens?
This cycle describes how carbon moves between the atmosphere, oceans, soil, and living things.
What is the carbon cycle?
This biologist pioneered the theory of evolution and natural selection. He used finches to support his theory.
Who is Charles Darwin?
These feet-like projections found on cells or single-celled organisms can be used to move around or grab food.
What are pseudopods?
This type of reaction releases heat, like burning wood in a fireplace.
What is an exothermic reaction?
This type of heat transfer does not require matter and can travel through empty space, like the warmth we feel from the Sun.
What is radiation?
This process describes the buildup of toxic chemicals in organisms higher up the food chain.
What is biomagnification?
This scientist proposed the heliocentric model of the solar system, suggesting the Earth revolves around the Sun.
Who is Nicolaus Copernicus?
