  •  This is defined as anything that has mass and takes up space.

what is matter?

100

In this state of matter, particles are locked in a pattern, strongly attracted to each other, and can only vibrate.

What is a solid?

100

 Heat always travels in this specific direction between objects of different temperatures.

What is from the warm object to the cooler object?

100

These are the non-living parts of an ecosystem that living things interact with.

What are abiotic factors?

100

 This type of ecological succession begins in an area with nothing but bare rock and no existing soil.

What is primary succession?

200

While a scientific law describes what happens in nature, this scientific term explains why it happens.

What is a theory

200

: This state of matter has a fixed volume but no fixed shape, allowing its particles to slide past one another.

What is a liquid?

200

 This type of heat transfer requires direct physical touch between solid matter, like walking barefoot on hot sand.

What is conduction?

200

 Organisms like mushrooms and bacteria belong to this group, which breaks down dead material to create fertile soil.

What are decomposers?

200

 These pioneer organisms are the first to grow on bare rock, slowly breaking it down to begin soil formation.

What are lichens?

300

 Fruit salad, pizza, and dirt are examples of this specific type of mixture where you can see the different parts.

What is a heterogenous mixture

300

 An ice cube melting on a hot day is an example of matter doing this to its heat energy.

What is absorbing heat?

300

This method of heat transfer occurs through waves and does not need any matter to travel through.

What is radiation?

300

This term refers to the specific place or "role" in an ecosystem that a certain organism is perfectly suited to fit into.

What is a niche?

300

 This type of succession occurs after a major disturbance, like a forest fire, in an area that already has nutrient-rich soil.

What is secondary succession?

400

 According to the Particle Theory, this factor directly determines the speed at which particles move.

What is temperature?

400

This term describes the phase change when a gas turns directly into a solid, such as hoarfrost forming.

 What is desublimation?

400

 A hot air balloon rises because of this type of heat transfer, which moves through liquids or gases using currents.

What is convection?

400

 Positioned at the very base of the trophic pyramid, these organisms use sunlight to make their own food via photosynthesis.

What are producers?

400

 Draining wetlands for agriculture or homes is an example of this category of human impact on ecosystems.

What is a negative impact?

500

 This type of uniform mixture looks like a single pure substance and is formed when a solute completely dissolves in a solvent.

What is a solution (or a homogeneous mixture)?

500

 Dry ice turning directly into a gas without becoming a liquid first is an example of this process.

What is sublimation?

500

Of the three main types of heat transfer, this is the only one responsible for bringing the sun's energy through the vacuum of space to Earth.

What is radiation?

500

 On a trophic pyramid, a bear or a human who eats both plants and other animals would be classified as this type of consumer.

What is a secondary consumer (or omnivore)?

500

 Cutting down trees for lumber but immediately planting new ones to replace them is an example of this positive human practice.

What is a sustainable practice?
