Atoms and Molecules
What is the difference between Atoms and Molecules
Atoms make Molecules
What is gravity
force of attraction between all matter
what 2 things happen when light waves pass from the air to water
it bends and slows down
what is the first step
define criteria and constraints
what is the term for light passing through different materials
transmission
What Atoms make H2O
2 Hydrogen and 1 Oxegan
what makes GRAVITY stronger
add mass add proximity
what is in white light
all the colors of the rainbow
what is the second step
researcher and develop model
what is better analog or digital and why
very little interference and noise
what is a example of law of conservation of mass
mass of what you start with you will end with that same mass
what is the difference between Kinetic and Potential Energy
Kinetic=moving=unbalanced
Potential=not moving=balanced
how do we see the color black
all color is absorbed
what is the third step
Analyze data and evaluate competing designs
what forces can effect objects without touching the directly
gravity magnetism and electricity
what is an electromagnet
magnet created with electricity
How can you increase potential energy
increase height or mass
how do we see the color orange
orange light is reflected o our eyes and all the other colors are absorbed
what is the fourth step
redesign to reach optimal design
if you raise the volume of a sound wave what happens
it gets louder
Name two ways to make electromagnets stronger
add more batteries add more coils
How can you increase kinetic energy
increase acceleration or mass
why does the block top get so hot in the summer
all colors absorbed builds up heat
what are all four steps put together
Define criteria and constraints
Research and develop model
Analyze data and evaluate competing design
Resign to reach optimal design
if you raise the wavelength of a light wave what will happen
changes color or type of light
