Tuesday's Question of the Day
Sexual reproduction involves the combination of genes
from two parents.
Asexual reproduction creates a genetically identical
offspring to the parent (one parent)
The illustration below shows how a strawberry plant
reproduces by asexual reproduction to form a new plant.
Describe how the new plant compares genetically with the
parent plant. Identify one advantage that asexual
reproduction might offer the strawberry plant. (2 points)

Sexual reproduction involves the combination of genes from two parents.

The illustration below shows how a strawberry plant reproduces by asexual
reproduction to form a new plant. Describe how the new plant compares genetically
with the parent plant. Identify one advantage that asexual reproduction might offer
the strawberry plant. (2 points)
Answer = The parent & the offspring
should be genetically indentical
(unless there is a mutation). One
advantage to reproducing asexually is
that since the parent has been able
to survive to reproduce in this
environment, it must be well-adapted,
so the offspring should be as well.

Thursday's Question of the Day
Topic: Mineral Identification
Mineral - a naturally occurring, inorganic (not made of
living material) solid that has a crystal structure and a
definite chemical composition
Minerals are identified according to several observable
characteristics: Color, Streak, Luster (how light reflects
from its surface), Density, Hardness (using Mohs Hardness
Scale), Crystal Structure, Cleavage/Fracture (how the
mineral breaks apart)
Rock - a solid mixture of minerals and other materials
March 19, 2013
Identify each mineral and provide two reasons to support
your answer. (3 points each)
Mineral #1
• Will scratch all common
minerals.
• A streak test can’t be preformed
because it doesn’t leave residue.
Mineral #2
• This mineral can be scratched
by a copper penny.
• Streak = white
• Distinguishing characteristic is
that this tastes like salt.

Mineral #2 HALITE
• This mineral can be scratched
by a copper penny.
• Streak = white
• Distinguishing characteristic is
that this tastes like salt.

Friday's Question of the Day!
The moon takes about 28 days to orbit the Earth, a length of time called a
lunar month. Because the same side of the moon is always illuminated by the
sun, it appears differently to us on Earth throughout the lunar cycle. A full
moon occurs when the entire face of the moon is lit up (from the Earth's
perspective). Quarter moons occur when the moon in our sky appears to be
half-lit. When none of the moon facing the Earth is lit, it is called a new
moon.
In what phase of the moon would it be on Days 1, 7, 14, and 21?
You may draw or write your answer.

Wednesday's Question of the Day!
BACKGROUND INFORMATION:
Cold fronts (look like icicles) bring
cooler air masses and usually drier
(as opposed to humid) air; they
often are accompanied by brief,
heavy downpours & gusty winds
Warm fronts (look like suns rising) bring
warmer air masses that are usually more
humid; they are often accompanied by light
precipitation for a day or two with a good
chance of overcast skies.
Stationary fronts mean the air
masses on both sides of the front
are not moving. Stationary means
not moving; weather would stay the
same for this area until one front
becomes unbalanced and causes a
change.
High pressure = clear skies, dry weather, gentle winds (there is high
pressure on Mother Nature for nice days)
Low pressure = cloudy, wet weather with strong, gusty winds (low
pressure means low chance for playing outside)

Wednesday's Question of the Day!
Using the weather map shown below, predict the sky conditions and
the chance of precipitation for Columbus, Ohio in the near future.
(2 points)
You can expect that Columbus, Ohio will get increasingly cloudy
skies as the cold front approaches (1 point). There will be a high
chance of rain after the cold front moves through Columbus with the
possibility of strong, gusty winds as the temperature drops (1 point).
