Nature of Science
We know more about science than we did 500 years ago. This tells us what?
What is that scientific knowledge changes over time based on evidence?
These large piles of silt can be found at the mouth of a river?
What are deltas?
Potential energy transforming into kinetic energy as a roller coaster goes down a hill expresses this Scientific Law
What is the Law of Conservation of Energy?
Order the following terms from least complex to most complex:
Organs, Molecules, Organisms, Atoms, Tissues, Cells, Organ Systems
Atoms, Molecules, Cells, Tissues, Organs, Organ Systems, Organisms
An air mass coming from Gulf of Mexico brings what kind of air?
warm, moist air
The observations, measurements, and other types of data that people gather to test, and support, and evaluate scientific explanations?
What is empirical evidence?
These spheres are involved when glaciers change from warming
What are cryosphere and hydrosphere?
If two basketballs are thrown at the hoop at the exact same time and they hit one another, this happens to the the ball's speed and this happens to the ball's direction
What is a change in both speed and direction?
Describe the three parts of the Cell Theory.
1 - All life is composed of cells
2 - Cells are the basic unit of life
3 - Cells arise from other cells
As the altitude increases, explain what happens to air pressure?
Air pressure decreases. There are fewer air particles as you go higher.
This is an orderly procedure carried out with the goal of verifying, refuting, or establishing the validity of a hypothesis.
What is a scientific experiment?
This tells us the weather conditions in an area over a long period of time
What is climate?
This occurs on a distance time graph when a person or object stops moving at a constant speed
What is a straight line?
In what three ways do cells maintain homeostasis?
1 - Extracting energy from food (CELLULAR RESPIRATION)
2 - Getting rid of waste
3 - Reproducing (MITOSIS)
What kind of weather is associated with high pressure system?
(Happy weather) – Sunny skies, clear day, few clouds
This is the process of obtaining information by using the senses
What is observation?
This heat transfer method occurs as warm air rises and displaces cooler air
What is convection?
This force occurs when the moon pulls on Earth's water creating tides
What is gravitational force?
What are the main differences between plant and animal cells?
Plant cells have chloroplasts and cell walls, while animal cells do not.
What does a barometer measure?
Air pressure
This is defining a problem, forming a hypothesis and making a prediction, then planning an investigation, identifiying variables, collecting and organizing data, interpreting data and analyzing information, and defending conclusions.
What is the scientific method?
What is conduction?
The Law of Universal Gravitation tells us that the amount of gravitation force exerted depends on these two factors
What are mass and distance?

What causes wind?
Movement of air from high to low pressure areas
