A student collects a sample of pond water in a jar to observe the microscopic algae that live in the water. The student then places a drop of the pond water on a microscope slide and observes it under a microscope. The drawings show what the student observed in the jar and on the slide.
The student observed microscopic algae only on the slide because algae grow larger when placed on a microscope slide.
The student observed microscopic algae on the slide because all of the algae cells were removed from the pond water on the microscope slide.
The student observed microscopic algae only on the slide because algae cells are too small to be seen without magnification by a microscope.
The student observed microscopic algae only on the slide because the water in the jar was too cloudy to see the algae.
- 2. Multiple Choice
A student observed a label found on raw chicken meat sold in the grocery store.
Some bacteria can harm humans because bacteria reproduce faster when they are cooked at high temperatures
Some bacteria can harm humans because bacteria become toxic when cooked at high temperatures
Some bacteria can harm humans because bacteria make food taste bad when it is not cooked properly.
Some bacteria can harm humans because bacteria can cause food poisoning when contaminated food is not cooked properly.
- 3. Multiple Choice
Cell X is shaped like a circle because it is an animal cell, which means it does not have a cell wall, and cell Y is shaped like a rectangle because it is a plant cell, which means it has a cell wall.
Cell X is shaped like a circle because it is a plant cell, which means it does not have a cell wall, and cell Y is shaped like a rectangle because it is an animal cell, which means it has a cell wall.
Cell X is shaped like a circle because it is an animal cell, which means it has a cell membrane, and cell Y is shaped like a rectangle because it is a plant cell, which means it does not have a cell membrane.
Cell X is shaped like a circle because it is a plant cell, which means it has a cell membrane, and cell Y is shaped like a rectangle because it is an animal cell, which means it does not have a cell membrane.

How fast are the cliff's eroding?
How many people live near cliffs?
How old are rock layers at the bottom of the cliff?
How can people stop the erosion of cliffs near the coast?
- 6. Multiple Choice
Which argument BEST describes the student's claim?
The student's claim is correct because water fills small cracks in rocks, freezes, and expands, making the cracks larger over time.
The student's claim is correct because the rock was carried from the top of the volcano to its base by a glacier, creating many cracks over time.
The student's claim is not correct because the rock was picked up by moving water and rolled against other rocks, smoothing its surface and causing cracks in a short period of time.
The student's claim is not correct because large cracks in rocks are caused when lava from a volcano covers the rock so its temperature rises and falls in a short period of time, causing it to break.
- 7. Multiple Choice
Which argument BEST supports the student's claim?
Ice forms because heat is added, causing particles to move faster. This makes the ice flow.
Ice forms because heat is removed, causing the particles to move slower. This makes the ice change its shape.
Ice forms because heat is removed, causing particles to move slower. This changes the water from a liquid to a solid.
Ice forms because heat is added, causing the particles to move faster. This changes the color of the water from clear to white.
- 8. Multiple Choice
Based on the evidence, which TWO arguments correctly match a magnet to its best use?
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 dropping 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.
