6th,
7th,
and 8th
Grades.
6th Grade Science
Students hoping to do well on Friday's test on Chapter 21 (Stars,
Galaxies & the Universe), should be able to do the following:
-
Name the 7 main sections of the EM spectrum, in order, from lowest frequency
to highest frequency.
-
Define the terms: wavelength, spectrograph, apparent brightness (or
magnitude), absolute brightness (or magnitude), parallax, and nebula.
-
Identify two different types of optical telescopes and how each type collects
light.
-
Identify other types of telescopes besides optical telescopes.
-
Name 5 different characteristics used to classify stars and describe the range
for each of those features. (For example, star color is one feature, which
ranges from red (coolest stars) to blue (hottest stars).
-
Locate and name the four main areas on the Hertzprung-Russell diagram.
-
Describe the life cycle of both a low/average mass star and that of a high
mass star from beginning (proto star) to end (black dwarf / neutron star or
black hole).
-
Distinguish among binary stars, eclipsing binary stars, trinary
(triple) stars, and multiple star systems and give an example of each.
-
Name and describe basic features of two types of star clusters and give an
example of each.
-
Describe basic features of bright, dark, and planetary nebulae.
-
Identify two types of bright nebulae.
-
Name and describe basic features of 3 different types of galaxies.
-
Name and describe the main feature of a sub-class of spiral galaxies.
-
Give a general description of the "Big Bang" theory and two pieces of evidence
that support the theory. (We'll cover this on Wednesday).
Official Disclaimer: As always, keep in mind that any material
presented in class may also appear on the test, even if it isnadvertently left
off of the study-guide. ☺
7th Grade Science
Students hoping to do well on Friday's test on Genetics and Heredity
(Sections 4-1 to 4-3) should be able to do the following:
-
Define the terms: Genetics, heredity, trait, allele, gene, genotype,
phenotype, dominant allele, recessive allele, co-dominant allele, homozygous
(purebred), heterozygous (hybrid).
-
Give a summary of the main points of Mendel's investigation of the traits of
pea plants.
-
Given a pair of parent organisms and a description of traits for each parent,
determine the genotype of each parent for each trait and make a Punnett square
for each trait.
-
Use one or two Punnett squares to determine the likelihood of a single trait
or a combination of traits to appear in an offspring.
-
Complete a diagram showing the distribution of chromosomes at different stages
during the process of meiosis.
Official Disclaimer: As always, keep in mind that any material
presented in class may also appear on the test, even if it is inadvertently
left off of the study-guide. ☺
8th Grade Science
Student's hoping to do well on this week's test on Chapter 12: Work and
Machines, should be able to do the following:
-
Define the terms: work and power, give an equation for
calculating each, and state the units used for stating work and for power.
-
State what a machine is and list the 3 main ways that machines make work
easier to do.
-
Calculate the input or output force, distance, or work of a machine knowing
two of the three related amounts.
-
State the formula for determining any machine's mechanical advantage, given
the machine's output and input forces.
-
State the formula for determing the efficiency of a machine given the
machine's output and input work.
-
Calculate the mechanical advantage, input force, or output force of a machine,
given two of the three amounts.
-
Calculate the efficiency, input work, or output work of a machine, given two
of the three amounts.
-
State and utilize the formulas for determining the mechanical advantage for an
inclined plane, wedge, lever, wheel-and-axle, and pulley.
-
Determine the input force/distance, output force/distance or mechanical
advantage of a simple machine based on sufficient given information.

presented in class may also appear on the test, even if it is inadvertently
left off of the study-guide. ☺
