Todd observes that his strawberry plant has grown little green strawberries. Which of these is a prediction Todd might make about his strawberry plant?
The green berries will ripen into red berries.
The strawberry plant is growing under an oak tree.
The strawberry plant doesn't have enough water.
The green berries are a new type of strawberry.
The green berries will ripen into red berries.
Letter B is not a prediction. Letter C is not correct because a plant with not enough water would die and not grow berries at all. Letter D does not make sense because Todd purchased a strawberry plant and strawberries are red.

Which of these is a conclusion rather than an observation?
This bear lives in a cold climate.
This bear has big teeth.
This bear has black claws.
This bear has small ears and eyes.
The bear lives in a cold climate.
This is a conclusions because you cannot see the bear’s climate in the picture. Observations are based only on what you can figure out using your senses. Conclusions involve putting those observations together to form or support an idea.

the eye is quicker than the ear
the thunder occurs much later than the lightning
sound travels faster through the atmosphere than light
light travels faster through the atmosphere than sound

An anemometer is used to show--
the speed of the wind
changes in temperature
the amount of rainfall
changes in air pressure
the speed of the wind
Changes in temperature are measured by a thermometer.
The amount of rainfall is measured by a rain gauge.
Changes in air pressure are measured by a barometer.

How is the Earth different from all of the other planets?
It has a breathable atmosphere.
It has a rocky surface.
It is warmed by the sun.
It rotates on its axis.
It has a breathable atmosphere.
Earth is the only planet in our solar system with a breathable atmosphere. Many of the other planets have a rocky surface. All planets are warmed by the sun (some more than others) and they all rotate on an axis.

a. radiant
b. reflected
c. refracted
d. radar
b. reflected
Reflected light bounces back. Refracted light bends.

Which type of plate boundary involves two plates moving away from each other?
Convergent
Divergent
Transform
Ocean trench
b. Divergent
Convergent- two plates move toward each other
Transform- two plates slide side to side

When a warm air masses gently slides on top of a cold air mass, and you have drizzly rain and then beautiful sunny weather, what front is it?
Cold front
Warm front
Occluded front
Stationary front
b. Warm front
A front is a boundary between 2 air masses (a warm and a cold)
A cold front is when a cold air mass moves into a warm air mass, it will get colder and we will have severe weather.
In an occluded front, a warm air mass is trapped between two cooler air masses.
In a stationary front, a warm and cold air pass push against one another and neither can move.

The color of his dog’s food dish
The kind of food he gives his dog
The amount of food he gives his dog
The time of day he feeds his dog
b. The kind of food he gives his dog
The manipulated variable is the variable that is being changed. Sandy is changing the kind of food he gives his dog to see which one his dog likes best.

Sandy grows roses along her walkway. The roses close to the street had more blooms than the roses close to the house. Which statement is a hypothesis Sandy could make about her roses?
There were many blooms on the roses near the house and fewer blooms on the roses closest to the street.
The roses near the house were taller but had fewer blooms.
The roses closest to the street had more blooms because they received more sunlight.
The roses close to the house had fewer blooms and leaves
c. The roses closest to the street had more blooms because they received more sunlight.
The other answer choices are observations. A hypothesis must be a testable statement; an idea about why something is occurring.
