Pat and Terry believe the color yellow attracts hummingbirds. They decided to test their hypothesis by doing an experiment in which they set up four hummingbird feeders with the same amount of food and placed them in locations only hummingbirds could reach. One feeder was yellow, one was red, one was blue, and one was clear. Each day for one week, Pat and Terry measured and recorded the amount of food left in each of the feeders. At the end of the experiment the red feeder had the least amount of food left in it. What conclusion should Pat and Terry reach?
A. The results support the theory that hummingbirds only like the color red.
B. The results could prove the theory that hummingbirds do not like the color yellow.
C. The results could support a hypothesis that hummingbirds do not like the food used.
D. Their results failed to support the hypothesis that hummingbirds are most attracted to the color yellow
D. Their results failed to support the hypothesis that hummingbirds are most attracted to the color yellow

Two objects have a certain gravitational force between them. What would happen if the mass of one of the objects suddenly increased?
A. The mass of the other object would increase
B. The distance between the objects would increase
C. The gravitational force of the objects would remain constant
D. The gravitational force between the objects would increase
D. The gravitational force between the objects would increase

A measure of the amount of matter present in a given volume of substance.
Density
200
what is the difference between mass and weight?
mass is the amount of matter in an object
weight is the force of gravity acting on that object
200
A _______ is a state of matter with a fixed shape and volume.
solid

A rocket burns fuel to create hot gases that explode violently out of the rocket engine. This explosion creates thrust. Thrust is a force that pushes the rocket upward. What force must thrust overcome in order to send a rocket up into space?
A. Gravity acting on the rocket
B. Gravity acting on the exploding gases
C. Friction between the rocket and the ground
D. Friction between the rocket and the exploding gases
A. Gravity acting on the rocket

Marcie wanted to find the density of a silver bracelet. She found that its mass was 21 grams and its volume was 2 cm3 . What was the density of the silver bracelet? Density = Mass/Volume.
A. 21 g/cm3
B. 10.5 g/cm3
C. 19 g/cm3
D. 2 g/cm3
B. 10.5 g/cm3
because...
Density = Mass/Volume
D= 21 g / 2 cm3 = 10.5g/cm3

C. temperature
D. volume
B. mass

A student heats a beaker of water. She measures the amount of time it takes the water to increase in temperature by 5 degrees Celsius. What type of scientific investigation is the student conducting?
A. comparative study
B. theoretical prediction
C. hypothetical analysis
D. observation experiment
D. observation experiment
because they are actively manipulating a variable (heating the water) and observing the resulting change in temperature over time.

A. Density
B. Mass
C. Volume
D. Weight
D. Weight

A. Hydrogen ions are found in acids.
B. Hydrogen gas is highly flammable.
C. Hydrogen ions react with oxygen ions.
D. Hydrogen gas is less dense than oxygen gas
D. Hydrogen gas is less dense than oxygen gas
because... this is the only statement describing a PHYSICAL PROPERTY

B. The two objects are made of the same substances.
C. The two objects are attracted by different amounts of gravitational force.
D. The two objects are measured by using a balance and a spring scale.
C. The two objects are attracted by different amounts of gravitational force.

For a laboratory exercise in class, a student is given a mixture of small pieces of iron, sand, water, and salt. What physical property could be used to best separate the iron from the other ingredients?
A. solubility
B. magnetism
C. melting point
D. electrical conductivity
B. magnetism
because... iron is magnetic, meaning it will be attracted to a magnet, allowing you to easily separate it from the other components in the mixture which are not magnetic.

Which of these is most needed for a study to be a valid scientific experiment?
A. results
B. observations
C. a control variable
D. a graph of the data
C. a control variable
because... to be considered reliable, as it allows for comparison between the experimental group and a group where the independent variable is not manipulated, ensuring the observed effects are truly due to the variable being tested
