This is the way scientists gather information using their senses and tools.
What is observation?

These materials are solid, nonliving, naturally formed, and have a crystalline structure. Gold, silver, and halite are examples.
What is a mineral?
100
The asteroid belt lies between these two planets.
What are Mars and Jupiter?
100
This part of a plant is where pollen is made.
What is the anther.
100
This property, demonstrated during a lab which involved placing cans of diet and regular soda into an aquarium full of water, can be calculated with this formula:
D= m/v
What is density?
200
This educated guess is often tested by a scientist in a controlled experiment.
What is a hypothesis?
200
This scale measures the hardness of mineral, or its resistance to being scratched.
What is the Mohs Scale of Hardness?
200
This characteristic of Earth causes seasonal change.
What is the tilt of Earth's axis?
200
This part of the plant is a sticky landing pad that catches pollen.
What is the stigma?
200
This cycle between plants and humans/animals helps to make sure living things have the right balance of the gases that they need.
What is the carbon dioxide/oxygen cycle?
300
This is the one thing that changes during a controlled experiment.
What is a variable?
300
This type of plate boundary is located where two tectonic plates are sliding alongside each other.
What is a transform boundary/
300
During this type of eclipse, the Earth comes between the sun and the moon.
What is a lunar eclipse?
300
These tubes inside plant stems carry water upward from the root throughout the rest of the plant.
What is xylem?
300
These materials are good conductors of heat and electricity.
What are metals?
400
This tool might be used by a scientist to measure the volume of a liquid.
What is a graduated cylinder?
400
This theory, formed by scientist Harry Hess, was used to prove that plate tectonic movement and continental drift are possible. It also explains how mid ocean ridges form.
What is sea-floor spreading?
400
This type of tide occurs when the Earth, sun, and moon are in a right-angle formation.
What is neap tide?
400
These tubes inside plant stems carry sugar produced during photosynthesis from the leaves downward to the rest of the plants.
What is phloem?
400
During this process of heat transfer, cold air sinks while hot air rises.
What is convection?
500
These units of liquid volume are equal to cubic centimeters.
What are mls?
500
This type of lava is thick, glossy, and slow-moving.
What is pahoehoe lava?
500
An asteroid that hit Earth in this location may have contributed to mass extinction of animals including dinosaurs.
What is the Yucatan Peninsula in Mexico?
500
These are pore-like structures in leaves that control water loss during transpiration.
What are stoma?
500
All waves on the electromagnetic spectrum, including light, are this type of wave.
