Scientific Process
Variable that you as the experimenter are changing in an experiment
Independent Variable
Two or more different elements chemically combined
The law of conservation of matter states:
Matter cannot be created nor destroyed
What equation allows you to calculate force acting on an object?
F=ma
How a massive star ends its life cycle
Becoming a black hole or neutron star
When finding what basketball brand bounces the highest, what would the dependent variable be?
How high the ball bounces
Two or more different elements/compounds physically combined (evenly mixed)
How many atoms in this chemical formula:
CaCO3
5
Newton's three laws are:
1 - An object in motion/rest will stay in motion/rest until an unbalanced force acts upon it
2 - F=ma
3 - For every action there's an equal/opposite reaction (action/reaction)
Where are the hottest, brightest stars located on the HR diagram?
Top Left Corner
What's this called: If the wilson ball is used then it will bounce the highest because it's made of better materials.
A hypothesis
Two or more elements/compounds physically combined (not evenly mixed)
How many atoms are in this chemical formula:
2(NH4)2SO4
30
What's the mass of a bicycle pushed by a force of 120N and accelerating at 10 m/s2?
12 kg
What are the 3 main pieces of evidence we discussed that are used to support the Big Bang Theory
1. Doppler Effect (galaxies moving away, universe expanding)
2. Composition of the universe (hydrogen/helium)
3. Cosmic Background Radiation (leftover heat/energy/radiation)
What's this called: How does the basketball brand affect how high the ball will bounce?
Testable Question
Name the PH levels of acids, bases and neutral substances
Acids: PH < 7
Bases: PH > 7
Neutral: PH = 7
Balance this chemical equation:
_Mg + _O2 --> _MgO
2Mg + 1O2 --> 2MgO
What's the relationship between frequency and wavelength? (high f = _ , low f = _)
High frequency = Short wavelength
Low frequency = Long wavelength
Most abundant elements found in stars (%)?
Hydrogen & Helium
What's the difference between qualitative and quantitative variables?
Qualitative: Observation describing an object (color, size, shape, etc.)
Quantitative: Amount of something using numbers
What's the difference between cohesion, adhesion and surface tension?
Cohesion: Like substances sticking together (water/water)
Adhesion: Different substances sticking together (water to bottle/anything else)
Surface Tension: Force called by water molecules holding together at the surface
Balance this chemical equation:
_CO2 + _H2O --> C6H12O6 + _CO2
6CO2 + 6H2O --> C6H12O6 + 6CO2
What are all of the waves on the electromagnetic spectrum (including ROY G BIV) in order?
Radio
Micro
Infrared
Visible Light (Red, Orange, Yellow, Green, Blue, Indigo, Violet)
Ultraviolet
X-Ray
Gamma Rays
What are the 3 galaxy types and what do they look like?
Spiral: Like pinwheel
Elliptical: Like a clump of light (football/oval shaped)
Irregular: Like a weird cloud (no definite shape)
