Even though the Sun has a mass 27 million times greater than the Moon, the Moon has a greater impact on the Earth’s tides. This is because:

The Moon is much closer to the Earth.

The Moon has more gravitational force than the Sun.

The Moon is made of solid elements instead of gases.

The Moon has a faster orbital period.

Which of the following scenarios is an example of an unbalanced force?

a golf ball being hit with a club

a car traveling constantly at 50 mph

a big truck stopped at a red light

Which of the following statements is NOT true about the organism that completes this food chain?

It derives its energy directly from the sun.

It depends on other animals for energy.

It can move from one place to another.

Which does not describe a predator/prey behavior?

A barnacle attaching itself to a whale.

Dolphins working in a team to roundup a school of fish.

An eagle soaring above a field looking for a mouse.

A polar bear walking on the sea ice searching for a seal.

Which of the following is an example of selective breeding in order to enhance a particular genetic trait?

Horses with fast gallops are chosen to produce offspring equipped for racing.

Rabbits with larger back legs and muscles are more adapted to escape predators.

Eagles with sharp claws are adapted to catching fish from a lake.

Owls have keen eye sight in order to spot prey at night.

Suppose you pull Nick, who is standing on a skateboard, using a rope at a constant acceleration. Nick’s friend, who weighs the same as Nick, then gets on the skateboard too. How is the force you have to apply to the rope affected to maintain the same constant acceleration?

The amount of force required is doubled.

There will be no change to the required amount of force.

The amount of force required is slightly increased.

The amount of force required is four-times as great.

Henry is investigating the properties of elements in section A. What are the general characteristics of elements from section A?

conducts heat and electricity, shiny, and solid

mostly gases and are very reactive

share properties of metals and nonmetals

liquids that are stable in pure form

CH 4 +2O 2 → CO 2 +2H 2 O How many atoms are there on the left side of the equation compared to the right side?

The left and right side have the same number of atoms.

The left side has more atoms than the right side.

The right side has more atoms than the left side.

It is impossible to know because it depends on the reaction speed.

Use this model of the Hertzsprung-Russell diagram to answer question. An astronomer discovers a new star that is very hot, but not very bright. What type of star did she discover?

an old star on the main sequence

Our Sun is a middle-aged star with an average temperature and brightness. What type of star is our Sun according to the Hertzburg-Russell diagram?

a star in the middle of the main sequence

a star on the upper left portion on the main sequence

Which of the following statements best describes the subatomic particle at location X?

The charge of the subatomic particle at location x is opposite of the charge at location y.

It has a very large mass and is negatively charged.

It has almost no mass and no charge.

It has a positive charge similar to location y.

How does the mass of location y compare to the mass at location x?

Location y has a mass multiple thousand times larger than location x.

Location y has a mass only slightly larger than location x.

Location x and y have the same mass.

Location x has a mass twice as large as location y.

Which of these atoms will be more reactive and why?

Atom B, because it gives up a valence electron.

Atom A, because it has fewer electrons.

Atom A, because it has unequal charges.

Atom B, because it more neutrons.

Felipe is observing how acetic acid (vinegar) and sodium bicarbonate (baking soda) react with one another in a volcano model. What evidence can Felipe look for to indicate a chemical reaction has taken place?

The volume of the acetic acid increases.

The density of the baking soda decreases.

During a science lab, Jessica records the following data when Liquid A (clear) and Liquid B (clear) are combined in a beaker: Did a chemical change occur? Why?

Yes, a new yellow liquid is formed

Yes, mixing any two unknown liquids will cause a chemical change

No, there was no change in temperature

No, there was no change in the state of matter

Which of the following pictures is an example of a chemical change?

ice melting in water in a beaker

Which of the following chemical equations for a reaction between carbon dioxide and water is considered balanced?

6CO 2 + 6H 2 O --> C 6 H 12 O 6 + 6O 2

3CO 2 + 6H 2 O --> C 6 H 12 O 6 + 3O 2

3CO 2 + 2H 2 O --> C 6 H 12 O 6 + 6O 2

CO 2 +H 2 O --> C 6 H 12 O 6 +O 2
