This process occurs in the leaves of green plants, using sunlight, carbon dioxide, and water to produce sugar and oxygen.

What is Photosynthesis
100

This is the temperature scale used by scientists that is based directly on the freezing and boiling points of water.

What is the Celsius Scale

100

This is the standard scientific unit used to measure weight and internal forces, rather than mass.

What is a Newton

100

This is the thinnest, coolest, and outermost solid layer of the Earth where all life exists.

What is the Crust

200

This sticky structure sits at the very top of the flower's center female stalk and is specifically designed to trap drifting pollen grains.

What is the Stigma

200

This specific type of heat transfer occurs through direct particle-to-particle contact within solid objects, like a metal spoon heating up in hot soup.

What is conduction

200

A beaver dam, brick wall and sand castle could all be categorized as this type of structure.

What is a mass structure

200

This family of rock forms when hot, molten magma or lava cools down and hardens into solid stone.

What is Igneous Rock

300

Unlike a deep, single taproot, this type of root system consists of a massive, shallow network of thin, branching roots.

What are Fibrous Roots

300

 This phase change occurs when a solid turns directly into a gas without melting into a liquid first.

What is Sublimation

300

This internal force acts inside a material when it is being pulled and stretched from opposite ends, like a rope in tug-of-war.

What is Tension 

300

This family of rock forms over millions of years when small pieces of sand and mud are packed and cemented together in layers.

What is Sedimentary Rock

400

This internal plant tissue acts like tiny drinking straws, transporting water and nutrients upward from the roots against gravity.

What is the Xylem

400

This term describes what happens to the temperature of a substance during a flat plateau on a heating curve while a phase change is actively taking place.

What is it stays the same.

400

This temporary, non-permanent weight is added to a structure by nature or people, such as snow piling up on top of a roof in winter.

What is a Live-Load

400

These looping thermal movements take place inside the Earth's mantle, driving the movement of the crust above.

What are Convection Currents

500

This is the process where humans intentionally choose parent plants with desirable traits to breed together, such as crossing a red rose and a yellow rose to make an orange rose.

What is selective breeding

500

This temperature measuring device, commonly used in household thermostats, bends when heated because it is made of two different metals that expand at completely different rates.

What is a bi-metallic strip

500

This type of structural failure happens when a material buckles or folds outward under a heavy crushing or compressive force.

What is Buckling

500

This is the thick, semi-fluid layer of the Earth located directly beneath the crust.

What is the Mantle
