Students perform an investigation to compare the relative specific heats of sand, water, and soil. They fill plastic cups with the same mass of each material, place a temperature probe in each sample, and put the samples the same distance beneath identical flood lamps. Students record temperature data for 2 minutes while the lamps are on, and continue recording data for 1 minute after the lamps are turned off. Which of the following is the dependent variable in this experiment?

the change in temperature of the materials

the amount of time the lamps are turned on and off

During a lesson on waves, Ms. Chavez asks her students to stand side-by-side in a long line and link elbows. She asks them to be ready to squat when someone tugs their elbow down and stand back up when someone tugs their elbow up. Ms. Chavez goes to one end of the line, links elbows, squats and stands back up. As she squats, she naturally tugs downward on the elbow of the student next to her, who then tugs downward on the next student and so on. As she stands again she naturally tugs upward on the student next to her, and the signal moves down the line. The result is a wave that starts with Ms. Chavez and travels down the line of students. Each student squats and stands as the wave passes. Which of the following concepts about waves is Ms. Chavez most likely trying to teach?

the nature of a transverse wave

the nature of a longitudinal wave

Which of the following activities best helps students practice the process skill of observing?

using a magnifying glass to inspect the small features on the surface of a leaf

using a thermometer to determine the temperature at which water boils

making a table to show the relative hardness of minerals

sorting rocks by the size of their crystals

Susanne and Xavier are workers on a road construction crew. When lifting a rock, Xavier lifts the rock straight up, but Susanne uses a lever, as shown. Neglecting any friction, which worker does the most work lifting the same rock to a height of 2 inches off the ground? Assume the weight of the lever is negligible.

Both do the same amount of work.

Susanne does more work because she must move the lever farther.

Xavier does more work because he must pull upward, whereas Susanne can push downward.

Xavier does more work because he uses only his muscles to lift the rock.

Which activity would be appropriate for a second-grade class studying the water cycle?

having groups use easily accessible materials (such as rocks, popsicle sticks, etc.) to build a 3D model of the water cycle

completing a worksheet that labels each part of the water cycle and how they work

having students engage with an online website that has various videos explaining the water cycle

researching the impact of global warming on the water cycle and writing a report

Which of the following would result if two objects with opposite electrostatic charges are placed near one another?

Following an investigation on how the length of shadows changes throughout the day, Mr. Vasquez would like to assess his students' knowledge of the relationship between shadow length and time. Which of the following would be the best assessment to use?

having students draw pictures of shadows at various times of the day

questioning the class about when the darkest shadows form

having students explain why shadow lengths change during the day

having students report on how shadows are formed

Heart disease is a major threat to human life in the United States. Which of the following lifestyle changes is the most likely to reduce the incidence of heart disease?`

During a unit on organisms and environments, Mr. Woodland wants his second-grade students to identify factors in the environment that affect plant growth. Students design investigations that involve growing bean plants in paper cups and exposing the plants to environmental variables of their choice. After the beans sprout, the students measure and record the heights of their bean plants. At the end of the investigation, students will be asked to present their data in a way that will be quick and easy to understand. Which of the following is the best way to incorporate technology into this lesson?

Have students record and graph their data in a spreadsheet that they can access each time they make a measurement.

Have students search the internet to help them figure out which environmental variables they can change and control.

Provide students with electronic balances for measuring the masses of their beans each day.

Have students take an online, multiple-choice test of their understanding after the activities are complete.

Which of the following functions are performed by a plant's stomata?

Transpiration of water out of the leaves.

Transport of glucose through the stem.

Absorption of minerals and water from the soil.

Absorption of light energy through the leaves.

Which of the following is true about stars?

Star color is dependent upon their temperature.

Stars generally fall into the same size range.

Stars generate heat and light through endergonic reactions.

Pressures driving natural selection include all of the following EXCEPT:

equal populations of all organisms

Which of the following is an example of a negative feedback system?

contractions during labor and childbirth

A student is struggling to differentiate between artificial selection and natural selection. Which of the following interventions would best help this student?

Asking students to pair up and create a Venn diagram of artificial selection and natural selection together.

Giving students a copy of the notes about the two types of selection.

Asking students to make a list of organisms that experience natural selection and organisms that experience artificial selection.

Having students re-read the textbook section over artificial selection and natural selection and write three sentences about it.

Certain plant species can reproduce asexually through the processes of budding or through spore dispersal. Which of the following is a disadvantage for plants that employ this type of reproduction?

All offspring are genetically identical, so a disease can wipe out an entire population.

High genetic diversity in the offspring makes it difficult for scientists to track mutations.

This method is quick, and many offspring can be produced in a short amount of time.

A large number of offspring can be made from one plant, so populations can be regrown easily.

Which of the following is a key characteristic of scientific inquiry?

Scientific theories are open to change as new information is discovered.

Scientific discovery is relative, depending on who carries out the research.

The results of experiments should only be communicated when scientists are sure the outcome proves a scientific law.

Scientific discoveries are more important than ethical decisions.

Which of the following environmental pressures would not be a primary contributor to the process of natural selection?

predator and prey relationships

Of the following, which contributes the most to water pollution in streams?

carbon dioxide from gasoline-powered vehicles

A third-grade science teacher is teaching a lesson on erosion. He wants to incorporate technology to help students explore these issues across history and in current climates around the world. An example of an appropriate activity would be to:

have students use the internet to find accounts of the Dust Bowl and current farming practices that prevent erosion.

show a short video that shows a graphic of erosion taking place.

have students find pictures of the Grand Canyon and other large landforms that have been created by erosion.

provide students with a list of helpful websites that give examples of erosion in other countries.

Which of the following is the responsibility of the teacher with regard to the use of chemicals?
