The picture shows two steep valleys and two rivers that join together and become one larger river in a wider valley. A student claims that both valleys have been formed by the same process over a long period of time. (See image. Click on it to enlarge.) Which argument BEST explains why the student’s claim is correct or incorrect?

• The student’s claim is correct; the evidence in the picture shows that both valleys were formed by the constructive force of deposition because flowing water carries large rocks from far away and drops them along a river, making the banks taller.

• The student’s claim is correct; the evidence in the picture shows that both valleys were formed by the destructive forces of weathering and erosion because flowing water breaks down rock and carries the small pieces downstream.

• The student’s claim is not correct; the evidence in the picture shows that valley 1 was formed by the constructive force of deposition because flowing water carries large rocks from far away and drops them along a river, making the banks taller, but valley 2 was formed by the destructive forces of weathering and erosion because flowing water breaks down rock and carries the small pieces downstream.

• The student’s claim is not correct; the evidence in the picture shows that valley 1 was formed by the destructive forces of weathering and erosion because flowing water breaks down rock and carries the small pieces downstream, but valley 2 was formed by the constructive force of deposition because flowing water carries large rocks from far away and drops them along a river, making the banks taller

Which question can be asked to find out which characteristic is a learned behavior?

• Do all eastern box turtles like the same food?

• Do all eastern box turtles hide in their shells when they are frightened?

• Do eastern box turtles in other states have the same color of spots?

• Do eastern box turtles in other states live for 50 years?

A student is comparing two types of magnets The student asks five questions and then finds the answers to the questions by experimenting with the magnets The results are shown in the table.

Based on the evidence, which TWO arguments correctly match a magnet to its best use?

• Magnet 1 should be used to pick up magnetic objects in one location and drop them off in another location because temporary magnets can be turned on and off

• Magnet 1 should be used to pick up magnetic objects in one location and drop them off in another location because temporary magnets can be turned on and off

• Magnet 2 should be used to pick up magnetic objects in places where there is no power supply because permanent magnets do not run out of energy

• Magnet 2 should be used to pick up large magnetic objects because permanent magnets are stronger than temporary magnets

Students are investigating chemical changes that occur in different materials. (DOK 3)

Which TWO investigations would provide evidence of a chemical change?

• Placing a liquid in a freezer until the liquid becomes a solid would provide evidence of a chemical change because the state of matter changes

• Using a saw to cut a solid into two different pieces would provide evidence of a chemical change because the pieces cannot be put back together

• Using a hot plate to heat a solid until it changes color and releases an odor would provide evidence of a chemical change because the particles cannot be changed back

• Using a magnet to remove a magnetic solid from a mixture that also contains nonmagnetic solids would provide evidence of a chemical change because the mixture cannot be mixed together again

• Placing two different liquids together in a beaker and observing that a solid forms when they mix would provide evidence of a chemical change because a new material is formed

The picture shows a hot spring in a forest.

The bacteria in this hot spring form mats that can serve as homes to insects. The heat from the spring allows insects to live on these mats even during cold winters. Which argument best supports that bacteria are beneficial to the forest ecosystem?

• The bacteria prevent snow from falling during the coldest months of the year.

• The bacteria produce nutrients for nearby trees during the coldest months of

  the year.

• The bacteria provide water for communities of fungi during the coldest

  months of the year.

• The bacteria protect food for birds and small mammals during the coldest

  months of the year.

Which of the following best describes the difference between static electricity and human-harnessed electricity? 

• Static electricity is a static discharge, while harnessed electricity is a continuous flow of charge.

• Static electricity is a natural phenomenon, while harnessed electricity is a natural phenomenon.

• Static electricity is a controlled flow of charge, while harnessed electricity is a build-up of charge on objects. 

• Static electricity is a build-up of charge on objects, while human-harnessed electricity is generated and controlled to power devices.

When one bulb in a series circuit containing several light bulbs burn out:

• the other bulbs burn brighter.

• 
  nothing changes in the rest of the circuit.

• none of the other lights bulbs will light up
