Which aspect of the space program is most likely to improve technology that would be applicable to improving shock absorption for earthquake-prone buildings?

probes sent to land on other planets

information sent back from solar orbits

Which of the following describes electromagnetic induction?

Forcing a conductor to move through a magnetic field produces a current in the conductor.

Electric charge can be stored on two parallel plates.

A chemical reaction establishes a voltage across two terminals.

Using electricity and a magnetic field will cause a coil of wire to turn.

A generator produces a voltage when a conductor, such as a coil of wire, is turned within the boundaries of a magnetic field. A generator changes the mechanical energy used to turn the coil into electrical energy.

A generator converts mechanical energy to electrical energy.

A generator produces heat energy from electrical energy.

A generator transforms electrical energy into mechanical energy.

A generator uses solar energy to generate electricity.

What is mechanical energy?

Mechanical energy is the sum of potential and kinetic energy in a system.

Mechanical energy is only kinetic energy.

Mechanical energy is the energy stored in chemical bonds.

Mechanical energy is the energy of motion only.

Mr. Sanford would like to show his students how DNA can be used in fields they may not consider "scientific". Which of the following activities would best accomplish this goal?

Lead students through an interactive forensic science activity in which they act as a detective who must match a DNA sample to find who is guilty of a crime.

Show students how a polymerase chain reaction can be used to copy DNA.

Explain the importance of using DNA to predict disorders in the medical field

Ask students to look at bacteria under a microscope. Have students draw what the DNA looks like to them and compare it to plant DNA viewed under a microscope.

A class is learning about the water cycle. Which of the following would be the most appropriate way to use technology to support their understanding of the movement of water through the water cycle?

Use a website that requires students to drag images representing each stage of the water cycle into their correct place on a diagram.

During class, complete a science experiment in which the students observe evaporation, using digital cameras to document and submit the results of their experiment.

Watch a video that describes the water cycle.

Use an app that allows students to digitally submit their answers to pre-assessment questions about the water cycle.

Which of the following is the greatest benefit of using computer simulations in a middle school science class?

Simulations allow students to experiment with materials they might not otherwise get to use due to safety concerns or financial factors.

Computer simulations leave less room for error.

Simulations allow students to work individually instead of in a group. This allows them to earn their own grade instead of depending on others.

The teacher can more easily monitor student progress with computer simulations.

A science teacher has her students run a section of the school track course and determine their speeds from their distances and times. This activity connects which three educational disciplines?

physics, mathematics, and physical education

science, language arts, and social studies

biology, chemistry, and physics
