you matter <3
What is matter?
anything that has mass and takes up space
what is periodic table, ya?
table that arranges elements in clear patterns based on similar properties
universe
everything that exists: all matter, energy, space
law of electric charges states...
opposite charges attract, like charges repel, charged objects attract neutral objects
photosynthesis
water + carbon dioxide + sun's energy into chemical energy for plants
joins metal components and is made of tin + lead
solder
Noble gases
group 18:
stable, don't react, colour/odour/tasteless
glow brightly when electric current passed through
solar nebula theory
solar system formed 5 B years ago from solar nebula that began to contract
your hair is frizzy...define static electricity
imbalance of positive and negative charges on object
levels of organization in ecosystem
organism, population, community, ecosystem, biome, biosphere
pure substance made of two/more elements chemically combined
chemical symbol
abbreviation for element's name
solar prominences...but sing it i guess
low energy gas eruptions from Sun's surface, extending into space
charging by friction
charge neutral object by rubbing it with charged object; contact allows electrons to be transferred
biogeochemical cycles...but say it like how someone in your class would explain it
movement of matter through biotic and abiotic environment (water, carbon, nitrogen)
Quick! If your science teacher gives you a true/false question, what do you write on the line if it's false?
The correct answer
Water is "odd", just like you! Why is that so?
solid form floats on liquid (ice is less dense)
difference between globular and open star clusters
glob: ball shaped collection of very old stars (thousands to millions)
open: young stars (six to thousands)
electrostatic series
chart that shows which materials are more likely to gain/lose electrons (top +; bottom -)
secondary succession
happens in partially disturbed ecosystem, like after forest fires
5 particle theory points...but do it in the accent.
All matter is made of tiny particles w/ empty space
Particles of one substance are the same
Particles in constant random motion
More energy = more faster movement
Particles attract each other
what is the isotope?
atom with the same number of protons but a different number of neutrons
light year, au, and light second calculations / km equivalents
ly: 9.46 x 10 ^ 12 km
au: 1.5 x 10 ^ 8
ls: 3 x 10 ^ 5
explain grounding...but do it in the accent
charged object comes into contact with large neutral object like earth and loses its net charge
acid precipitation and its impacts
caused by release of sulfur dioxides and nitrogen oxides
depletes nutrients from soil, respiratory problems, $
