Scientific Method
Where do we record our data during an experiement?
Data table
What is the basic unit of living things?
A cell
What the basic unit of matter?
What do we call water or ice falling from the sky?
Precipitation
What are tectonic plates?
Large sections of the Earth's crust that are broken apart
What do we call a test that is done to prove a hypothesis?
An experiment
Name the levels of body organization from smallest to largest.
Cells, Tissues, Organs, Organ Systems, Organism
Which way does heat flow or energy move?
From warmer objects (high energy) to colder objects (low energy).
Amount of water vapor in the air
humidity
Explain one evidence that continents used to be touching.
Coastlines fit like puzzle pieces
Fossil Distribution
Ancient Climate
What is a hypothesis?
An educated guess to explain the scientific question
What is the cell organelle that acts as a boundary of the cell, letting things in and out?
The cell membrane
What happens to particles when they gain energy?
They move faster and spread apart
What creates the largest convection currents that forms powerful storms, like a Kona Low?
Large temperature differences between the surface temps and air temperatures
Where is new crust formed?
At mid-ocean ridges and divergent boundaries
What is the variable you manipulate, control, or change in an experiment?
The independent variable
Name two components of the blood and explain their function
Red blood cells - deliver oxygen
White blood cells - fights infections
Plasma - delivers nutrients and takes away waste
Platelets - stops bleeding
Describe the three main types of thermal energy transfer.
Conduction - through particle contact
Convection - particles rising and falling in a fluid
Radiation - Electromagentic waves (like from the sun)
Explain why we need water vapor, cold temperatures, and cloud condensation nuclei to form clouds.
Water vapor - clouds are made from water droplets
Cold temperatures - to force water vapor to condense into water vapor
Condensation nuclei - water droplets must condense onto a solid surface
Age of rocks become older as you move away from the mid ocean ridge
Explain why changing only one variable at a time in an experiment is important.
To isolate the effect of the independent variable so you can tell what has caused the change.
What does a cell replicate during mitosis in order to create a new, identical daughter cell?
The DNA in the nucleus
What is the different between thermal energy and temperature?
Thermal energy is the TOTAL kinetic energy in a substance, but temperature is the AVERAGE kinetic energy
Explain one way how low pressure creates storm systems
Explain how a subduction creates a volcano.
The crust gets pushed in the mantle during subduction, melts into magma, and then the magma gets pushed up to form a volcano.
