Nature of Science
The act, practice, or power of NOTICING.
Energy is defined as _______________________.
When liquid water heats up enough to change into a gas.
Evaporation
The Earth is ________________ due to human activity.
*heating
*cooling
*staying the same
*becoming windier
HEATING
The smallest unit of life is _________.
a CELL
A statement that has been proven to be true.
Fact
The energy of MOTION.
Kinetic Energy
The movement of water between the atmosphere, Earth's oceans, and land.
The Water Cycle
Greenhouse Gases...
*allow heat to escape to space
*don't have an effect on heating/cooling
*trap heat near Earth's surface
*have no effect on Earth anymore
Greenhouse Gases.... trap heat near Earth's surface.
Name 2 organelles that are found in PLANT CELLS but not in Animal Cells.
*Cell Wall
*Chloroplast
A statement based on a belief or opinion that can be supported by evidence and data.
CLAIM
Anything that has mass and takes up space.
Matter
When water vapor cools and turns back into droplets of liquid water (like a cloud, or dew on grass).
Condense / Condensation
What is the main Greenhouse Gas affecting the Earth?
Carbonn Dioxide
Which body system controls most others, including involuntary actions like blinking, breathing, and heart beating?
NERVOUS System
What are the 3 types of variables in an experiment?
*Control Variable(s)
*Independent Variable
*Dependent Variable
As temperature of an object increases, the thermal energy _________________, causing the molecules to move ________________.
As temperature of an object increases, the thermal energy INCREASES, causing the molecules to move FASTER.
As you climb higher up a mountain (higher into the atmosphere), why does it become more difficult to breathe?
The higher in the atmosphere, the less DENSE the air, meaning the oxygen molecules are more spread out, causing each breath to have less oxygen.
What are 2 activities humans are doing that create MORE greenhouse gases in our atmosphere?
*Answers will vary*
How can you callcuate the probability that offspring will have (show) a certain genetic trait? (Like having black hair/fur instead of white)
Use a PUNNETT SQUARE
The type of variable being TESTED in an experiment.
INDEPENDENT (Manitpulated) Variable
What is the LAW OF CONSERVATION of ENERGY?
Energy can NOT be created or destroyed.
Earth is a sphere and tilted on its axis, so different regions on Earth receive different amounts of energy from the Sun. This uneven heating causes Earth's surface and atmosphere to be warmer near the equator than near the poles.
What are 2 activities humans are doing that are REDUCING the amount of greenhouse gases in the atmosphere?
*Answers will vary*
Explain the difference between HOMOZYGOUS and HETEROZYGOUS alleles.
Homozygous and heterozygous are terms that are used to describe allele pairs. Individuals carrying two identical alleles (RR or rr) are known as homozygous. While individual organisms bearing different alleles (Rr) are known as heterozygous.
