SSA Quiz #1 - NOS & Properties of Matter

[7.N.3.1] What is the difference between a scientific law and a scientific theory?

• Theories are upgraded into laws once they are proven.

• Laws use mathematical explanations and theories do not.

• Laws describe what happens, but theories explain how or why.

• Theories combine several laws into one.

[8.N.1.2] Which statement below is an example of repetition?

• Pour 50 milliliters (mL) of water down four inclined surfaces.

• Roll a marble down the ramp from a height of 10 centimeters (cm), 20 cm, and 30 cm.

• Take the mass of five rocks separately and then determine the average mass in grams (g).

• Conduct four trials of counting bubbles produced by a water plant for one minute (min) each.

[7.N.2.1] Scientists began exploring the ideas that make up the current atomic theory more than 2,500 years ago. Since that time, many models of the atom that were once accepted by scientists have been abandoned and replaced. Which explains why atomic models have changed over time? 

• A model is abandoned when it is discovered to have limitations.

• New models have been developed as new information is discovered.

• The microscope allowed scientists to closely inspect insects.

• The telephone allowed scientists to communicate much more easily.

[8.N.1.3] Which statement is the BEST argument for a hypothesis that has evidence to reinforce its claim?

• The results prove the hypothesis is correct.

• The results create the hypothesis.

• The results support the hypothesis.

• The results change the hypothesis.

[6.N.1.4] Austin and Jose are trying to understand water tension. They are trying to rest paper clips on the surface of a cup of water as shown below. Austin wants to put all of the paper clips on the water himself. Jose wants to take turns placing paper clips on the water’s surface. Austin argues that Jose’s plan introduces uncontrolled variables. Why does Jose’s method introduce uncontrolled variables?

• A scientist always conducts an experiment by himself or herself.

• If both students add paper clips, they will use twice as many paper clips.

• It will be difficult to record the results if both students are adding paper clips.

• The results will be inconsistent because each student’s technique will be different.

[7.N.2.3] Examine this model of the planets in our Solar System.  Which information does this model NOT give about the planets?

• order of the planets

• relative size of the planets

• appearance of the planets

• relative distances between planets

[8.N.1.1] Keesha did an experiment to study the rate of photosynthesis in the water plant Elodea. She placed a piece of Elodea in a beaker of water and set the beaker 10 centimeters (cm) from a light source. She counted the bubbles released from the plant every minute for five minutes. She repeated the process two more times. First, she moved the light to 20 cm from the beaker, and then she moved the light to 30 cm from the beaker.  Keesha’s setup and data are shown in the picture. What is the dependent variable (outcome variable) in this experiment?

• The number of bubbles produced.

• The type of plant placed in the beaker.

• The distance of the light source from the plant.

• The amount of time the bubbles were counted.

[6.N.2.2] Scientific knowledge may change as new evidence or information is discovered. Which of the following would NOT be a result of new scientific research and information?

• The process of binomial nomenclature is used to assign a name to a recently identified plant species.

• An endangered monkey species is put in a reserve for protection from extinction.

• A newly discovered chemical element will be added to the periodic table of elements.

• A nonnative plant species will begin to reproduce rapidly after being introduced into a swamp ecosystem.

[7.N.1.5] The model in the picture represents a rocket in flight. Which would be the BEST use of this model by a scientist?

• To model one-directional forces, as the rocket is affected only by one force.

• To model the idea of zero gravity, as the rocket is not affected by gravity.

• To model the transition between the kinetic and potential energy of the rocket.

• To model the effects of wind resistance on the rocket’s descent to the ground.

[7.N.1.3] Scientists do many types of work. Their work often included making field observations, conducting surveys, creating models, and carrying out experiments.  Which description characterizes an experiment?

• Observation of plants and animals in their natural environment.

• Physical or mathematical representation of an object or process.

• An organized procedure to study something under controlled conditions.

• Collection of data from an unregulated source for comparative purposes.
