GA Milestone Review Science

A student is studying the formation of the Himalayas. The student finds a picture and learns that the mountain range formed when the Indian Plate collided with the Eurasian Plate. The student uses a picture to design a model that will show classmates how the Himalayas formed. step 1: Use light-colored clay to make the shape of the Eurasian Plate. step 2: Use dark-colored clay to make the shape of the Indian Plate. step 3: Slowly push the dark-colored plate toward the light-colored plate. step 4: Observe and record how the shapes of both plates change when the edges push against each other. Which data could the student collect using the BEST model from the steps?

• the changing distance between the two plates

• the time it takes for the two plates to collide

• the mass of the materials used to make the two plates

• the changing height of the edge where the two plates collide

• 
• 

• step 5: Connect a test material to the open ends of wire 1 and wire 3.

  step 6: Make observations, and repeat step 5 with a different test material.

  conclusion: If the bulb lights up, the material is a conductor. If the bulb does not light up, the material

  is an insulator.

• step 5: Connect a test material to the open ends of wire 1 and wire 3.

  step 6: Make observations, and repeat step 5 with a different test material.

  conclusion: If the bulb lights up, the material is an insulator. If the bulb does not light up, the material

  is a conductor.

• step 5: Connect the open ends of wire 1 and wire 3 to each other to complete the circuit.

  step 6: Touch a test material to the completed circuit, and record observations.

  conclusion: If the bulb lights up, the material is an insulator. If the bulb does not light up, the material

  is a conductor.

• step 5: Connect the open ends of wire 1 and wire 3 to each other to complete the circuit.

  step 6: Touch a test material to the completed circuit, and record observations.

  conclusion: If the bulb lights up, the material is a conductor. If the bulb does not light up, the material

  is an insulator.

• Magnet 1 should be used to pick up many small magnetic objects at once because the temporary magnet can pick up as many objects as the permanent magnet can.

• 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 can be used in all the ways magnet 2 is used because temporary magnets can be made stronger or weaker and permanent magnets cannot.

• 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.

A student is investigating chemical changes by using different materials. Which investigation would provide evidence of a chemical change and why?

• Melting a solid with fire would provide evidence of a chemical change because the solid would change

  shape.

• Cutting cardboard into many smaller pieces would provide evidence of a chemical change because the

  pieces cannot be put back together.

• Placing a solid into hot water and stirring while the solid dissolves would provide evidence of a

  chemical change because the dissolved material is lost.

• Combining two liquids that give off heat and gas would provide evidence of a chemical change because

  the particles react to make a new material with different properties.

Students are investigating chemical changes that occur in different materials. 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.

• 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.

• Placing a mixture containing a solid and a liquid on a windowsill and letting the liquid evaporate would

  provide evidence of a chemical change because the evaporated material is lost.
