Experimental Design
This is a testable prediction that explains what you think will happen in an experiment.
What is a hypothesis?
A liquid has a density of 1.25 g/mL and a mass of 87.5g.
What is the volume of the liquid?
what is 70mL
What unit of measurement is used for mass?
What is grams?
This is anything that has mass and takes up space.
What is matter?
This subatomic particle has a positive charge.
What is a proton?
This type of spectrum shows the band of colors?
What is a emission spectrum?
DAILY DOUBLE:
This variable is purposely changed by the scientist during an experiment.
What is the independent variable?
A solid object occupies 35.0 cm³ and has a density of 2.70 g/cm³
What is 94.5 g
What unit of measurement is used for density?
g/cm3 or g/mL
DAILY DOUBLE:
This term describes the ability to do work or cause change.
What is energy
This subatomic particle has no charge.
What is a neutron?
Dark lines in a star’s spectrum indicate this.
What is absorption of specific wavelengths by elements?
This variable is measured or observed as a result of the experiment.
What is dependent variable?
A metal cube has a mass of 54.0 g and a volume of 20.0 mL.
what is 2.7 g/mL?
DAILY DOUBLE:
What is the unit of measurement for energy?
What is a joule?
As wavelength decreases, frequency and energy do what?
What is increases?
DAILY DOUBLE:
The atomic number tells you the number of these particles in an atom.
What are protons?
What determines the fate of a star?
What is its initial mass?
These are factors that are kept the same to ensure a fair test.
What are constants?
A student measures a rock by water displacement. The water level rises from 75.0 mL to 92.0 mL. The rock’s mass is 44.2 g.
a. What is the volume of the rock?
b. What is its density?
What is 17cm3
What is 2.6g/cm3
A block of aluminum occupies a volume of 15.0 mL and weighs 40.5 g. What is its density?
2.70g/mL
ROYGBIV represents which area of the EM spectrum?
What is visible light?
This process combines hydrogen atoms to form helium and releases energy.
What is nuclear fusion?
DAILY DOUBLE:
Fusion of this element marks the beginning of the end of a star’s life cycle.
What is Iron?
Explain why controlling variables is important in experimental design.
What is to ensure that results are due to the independent variable and not other factors?
What are Mr. Willis' two favorite sports that he does?
hehe good for you for choosing the hardest question here's a freebe :)
What is biking and skiing?
What is the mass of the ethyl alcohol that exactly fills a 200.0 mL container? The density of ethyl alcohol is 0.789 g/mL
157.8g
Put the electromagnetic spectrum in order from lowest to highest energy.
What are radio, microwave, infrared, visible light, ultraviolet, X-rays, gamma rays?
Why does a large amount of hydrogen and helium indicate a young star?
What is because it has not yet fused much of its fuel into heavier elements?
What are the three different paths a star can take when it dies?
What is Blackhole, Neutron Star, Dwarf Star
