Jessica conducted an experiment to test the preferred habitat of crickets in a terrarium. She placed potting soil in the terrarium then created different environments in each section. In one section she placed wet paper towels to simulate a humid habitat, a small heater in another section to simulate a warm dry environment, and small pieces of bark in another to simulate a habitat with shelter. The final section she left as just plain soil. She released 24 crickets into the center of the terrarium which was covered with a black cloth. After 4 days, Jessica removed the cover and counted the number of crickets in each section, then repeated this process every other day for 3 weeks. Jessica consistently found more crickets in the section with wet paper towels.

What is the independent variable?

• The amount of soil in the terrarium

• The type of habitat being simulated

• The number of crickets placed in the terrarium

• The lighting in the environment

David, an ornithologist, notices that a particular group of robins appears during the spring months near his research station and disappears during fall months. David hypothesizes that the robins migrate south to warmer regions with more insects during the winter months. Which procedure should David use to test his hypothesis?

• Observe the direction the robins travel when they depart in the fall

• Set up observation stations in the south to verify the time of year that robins arrive

• Tag the robins with GPS transmitters and track their movement

• Survey local and southern residents about robin sightings in their areas

Tyler believes that he memorizes vocabulary words better and faster when he listens to classical music. His parents say that music is distracting when studying. Tyler decides to test the impact of classical music on his vocabulary memorization. On Monday, Wednesday, and Friday he studies vocabulary words while listening to classical music and in silence, then counts the number of words memorized in each scenario. He recorded his results in the data table to the left.

• His hypothesis that classical music increases his memorization ability was not true

• His hypothesis that classical music increases his memorization ability was proven

• His hypothesis that classical music increases his memorization ability was not supported

• His hypothesis that classical music increases his memorization ability was supported

Amanda tests a hypothesis that the darker of two paper materials will absorb heat from a lamp better than the lighter material. She places equal amounts of ice cubes on two different colored papers under identical heat lamps. One paper is white, and the other paper is black. She records her results in a chart.

How are these experimental results valuable to Amanda?

• The hypothesis was not supported, so other materials should be tested

• The hypothesis was not supported, and no further experimentation needs to be conducted

• The hypothesis was supported, and no further experimentation needs to be conducted

• The hypothesis was supported, so other materials should be tested

Lily has done an experiment to find out whether bean plants grow faster under fluorescent lighting or incandescent lighting. She found that fluorescent lighting made the plants grow three centimeters faster over a period of four weeks. She gave her notes to Antonio, who did the same experiment with very similar results.

• repetition

• plagiarism

• replication

• pseudoscience

Grace and William have performed an experiment and are not sure their results are valid. What should they do to check their results?

• change their lab report

• change their hypothesis to match their results

• average their results

• repeat the same experiment multiple times

Each student recorded data showing the amount of rainfall in centimeters that fell in each of four weeks at school. Based on this data, why is it important to use replication in scientific investigation?

• to provide the same results by the same person during investigations

• to find inconsistencies during investigations

• to ensure accuracy during investigations

What are models used for in science?

• Represent an idea, object or process that cannot be experienced in daily life

• It is the controlled variable in any experiment

• To test a hypothesis written as an if, then, because statement

• Perform an experiment and graph the results

Two types of models can be used to show the details of volcanic eruptions. Physical Model: A 3D foam and clay model showing volcano structure Computer Simulation Model: A digital animation showing magma flow and eruption processes Which of the following best describes a limitation of the physical model but NOT the computer simulation model?

• a) It does not contain the correct information about the structure of volcanoes

• b) It cannot represent the actual movement that occurs during eruptions

• c) It does not represent the main parts of volcanic systems

• d) It cannot represent the different temperatures involved in eruptions
