1. Gas laws - Correct Answer: -Charles' law: as temperature goes up, the volume goes up
(this is why the saucepan lid rattles when you're boiling water)
-Boyle's law: as pressure goes down, volume goes up (as a balloon floats up and goes thru less
pressure, the balloon gets so large that the rubber rips)
2. pH - Correct Answer: Stands for "the potential for hydrogen". Acidic <------> basic
(alkaline)
-pure water is neutral (ph 7)
-ocean water, hand soap, ammonia, bleach, lye is basic
-coffee, beer, vinegar, gastric acid, lead battery acid is acid
*acid is usually food or biological
*alkalines are usually cleaning products
3. The law of gravity - Correct Answer: The more massive two things are, the greater the
gravitational force between them. However, the further apart two things are, the lesser the
gravitational force is.
G (mass of object 1 X mass of object 2 / distance between the two squared ^2)
4. Newton's laws of motion - Correct Answer: 1) inertia: an object in motion, stays in
motion. An object in rest stays in rest.
,2) acceleration: the more mass, the more force. The more acceleration, the more force.
(force=mass x acceleration)
3) reciprocal actions: for every action, there is an equal and opposite reaction.
5. Kinetic energy - Correct Answer: Energy in motion
6. Potential energy - Correct Answer: Stored energy (like when a ball is thrown up and is
about to come back down)
7. Shamus can paint the barn in 6 hours, and Ishmael can paint the barn in 7 hours. How long
will it take them to paint the barn together? - Correct Answer: 1/6+1/7=1/x
8. Quantum theory - Correct Answer: Matter and energy have the properties of both
particles and waves
9. How can electricity be used to power a light bulb? - Correct Answer: Electrons want to
ground out (bond with other atoms). Give electrons a good conductor (type of wiring) that
creates their path. When the light switch flips on, it closes a path in the conductor and electrons
are forced into the light bulb. The filament in the light bulb is made of a metal that provides
resistance (makes it harder for electrons to travel through). Electrons really have to push their
way through and this causes friction on the metal and it gets so hot that it creates a light.
10. Electrolysis - Correct Answer: Method of separating ions by passing electrical current
through the substance. The anode (positively charged) attracts negatively charged ions. The
cathode (negative) attracts positive ions.
11. Ways that heat is transferred - Correct Answer: -conduction: occurs when fast moving
molecules collide with slower ones (this is why the handle of a spoon in a bowl of hot soup
carries some warmth)
-convection: a hotter portion moves up and a cooler portion fills that space.
,-radiation: when heat is transmitted in the form of electromagnetic waves. High intensity
reaction.
12. Wave lengths - Correct Answer: -longest wavelength-----> shorter
radio waves -->infrared (heat)--> visible light (red-> orange-> yellow-> green-> blue-> violet)-->
ultraviolet light-->xray-->gamma rays
13. Reflection vs. refraction - Correct Answer: Reflection: light strikes an object and
bounces off it
Refraction: bending of light waves. (this is why we have rainbows) (this is why objects in a tank
of water looks different)
14. Light that we see - Correct Answer: The color that we see (for example, a yellow flower)
is actually the light/wavelength that is NOT absorbed
If something is white, it is reflecting all wavelengths of light. If it appears black, it is either
producing no light or it is absorbing every wavelength of light (this is why black asphalt gets so
much hotter than white cement)
15. Sound waves - Correct Answer: Are different from light waves in the sense that they
require a medium to travel and they travel much slower than light waves.
Doppler effect: why a car driving by you creates a higher pitch frequency driving past you and a
lower frequency as it passes you. The waves in front of the car are closer together (higher
frequency) and the waves behind are further apart.
16. Animal cells - Correct Answer: Comprised of a number of organelles:
, -nucleus: the brain of the cell. Houses the DNA. The control center.
-mitochondria: powerhouse of the cell. Create energy
-ribosomes: house RNA. Help to translate DNA to create proteins.
-cytoplasm: everything that's inside the cell membrane (goo)
-cell membrane: "selectively permeable"- can choose what to let in or out.
17. Plant cells - Correct Answer: *has every organelle that the animal cell and also has
-vacuole: storage container. Like the bag on a vacuum cleaner. Also helps with cell movement
-chloroplast: green (because of chlorophyll).
-cell wall: thick outer layer that protect the structure. This is why humans and animals need
skeletons (because our cells are soft) and plants don't.
18. Mitosis (PMAT) - Correct Answer: -prophase: chromosomes of the cell duplicate
-metaphase: lines up across the center and a spindle starts to grow
-anaphase: cell begins to split. Genetic material moves to opposite sides of the cell.
-telophase: cutting action completes and cell pulls apart into two child cells.
19. Diploid vs. haploid - Correct Answer: Diploid cells (created after mitosis) can begin the
process again whereas haploid cells (after meiosis) must join with another gamete in order to
continue division.
20. The nervous system - Correct Answer: Brain, spinal cord, and other nerves. The nerve
cells all look like brooms. The end whiskers of the broom are called dendrites-they receive
information and pass it through what looks like the broom handle (the axon). The axon is
wrapped with the myelin sheath.
-cerebral cortex: wrinkly outer layer of brain. Made up of 4 lobes. Responsible for things like
spacial awareness, conscious reasoning, language ability, and ability to process vision. Houses
the thalamus amygdala, and the hippocampus
