Measurement
What is one type of measurement you can make?
Length, Mass, Volume
How many planets are in the solar system?
8 (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune)
What are the three subatomic particles?
Proton, Neutron, Electron
Name an example of a conductor from the conductivity lab
Paper clip, Lead/Graphite, Nails
What is the charge of a neutral atom that gains 3 electrons?
-3
What is volume?
How much space matter takes up
Name one fact about the gas giants that makes them different from the terrestrial planets.
Furthest from the sun, very large, low density, made of gases (Hydrogen and Helium).
How many valence electrons do Halogens have?
7
A neutral object and a positively charged object will:
Attract
What is the overall charge of an object with 6 protons and 4 electrons?
+2
What is the equation used to calculate density?
Density = Mass/Volume
What celestial body originates at the edge of the solar system and often has a "tail" coming off of it?
Comet
What element is found in Group 2 Period 3 on the periodic table?
Magnesium (Mg)
List two examples of Non-Renewable Energy Sources
Oil, Coal, Nuclear, Natural Gas
0.51 g/mL
Object A sinks in water faster than object B. Is object A more or less dense than object B?
More dense. The densest object sinks the fastest.
What is the difference between a solar eclipse and a lunar eclipse?
Solar - moon passes between sun and earth
Lunar - earth passes between sun and moon
How many neutrons are in a neutral atom of Carbon?
6 neutrons
(Atomic Mass = 12, # of Protons = 6)
12 - 6 = 6
Name the three components required for a circuit
Power source, load, wires
How many of each element are present in the compound C2H5OH?
Carbon - 2
Hydrogen - 6
Oxygen - 1
Describe the displacement method for measuring volume.
- Fill up container with water
- Submerge object
- Measure amount of water displaced (This is the volume)
What is the greenhouse effect?
Some of the light from the sun bounces off the surface of the planet, but gases in our atmosphere (mostly carbon dioxide) prevent it from escaping back into space. This is called the Greenhouse Effect, and it is also responsible for warming the planet.
Counting the amount of trees planted in a scientific experiment is an example of what type of observation?
Quantitative
What is the load in a circuit?
Something that converts the electrical energy into useable energy (e.g. light bulb)
How many of each element are present in the compound Be2(SO4)2?
Beryllium - 2
Sulfur - 2
Oxygen - 8
