Identify the test and outcome variable from the prompt.
A consumer group wants to find out which of two new car models gets the best gas mileage. A car’s gas mileage is the number of miles a car can go for each gallon of gas it uses. They decide to fill the gas tanks of each car with the same amount of gas and compare how far each car goes. They use “regular” grade gas in both cars.
test variable- type of car model
outcome variable- number of miles a car can go for each gallon of gas it uses (gas mileage)

Name one landform found in Florida and name one landform not found in Florida.
Found in Florida= coastline, lake, delta, river, dunes,
Not found in Florida = glaciers, mountain

Scientists studying a breed of tuna noticed that some of the tuna could swim faster than others. After 10 years, the number of these "fast swimming" tuna outnumbered the slower tuna.
What could account for this population change?
slow swimming tuna were hunted and eaten by predators, fast swimming tuna were able to survive.

Jayden was observing a specific spot in the night sky with his telescope. He could tell an object was in the area he was observing, but couldn’t figure out what it was. He wrote down his observations below:
Made of mostly Hydrogen gas and dust
Larger than a solar system
Smaller than a galaxy
What object was Jayden observing?
Nebula

Krystal, Alyssa, and Jeff are doing an experiment to check how far a paper plane can fly. They all make their own paper plane using the same paper and each student throws their plane. Krystals plane flew the farthest, Alyssa plane was second and Jeff's plane was last.
What is the error in their investigation?
too many test variables, not enough constant to male each trial fair.

Explain how a river is formed.
River water flows and carries all the sediment to the mouth of the river and deposits the sand.

Millions of years ago, a mass extinction of nearly all the dinosaurs occurred. This extinction included the herbivore Protoceratops. Many scientists think that a massive meteorite crashed into Earth. The impact of this meteorite sent up large clouds of dust that blocked out sunlight for months or even years.
Explain how the impact could have caused Protoceratops to become extinct?
No sunlight means plants cannot grow so all herbivores starved to death.

What is the definition for apparent magnitude?
AND
What number represent the brightest of objects on the apparent magnitude scale?
How bright a star appears from Earth.
-30 represents the brightest object for apparent magnitude
