5th Grade Science: EOY Assessment Part 1

A student sets up an experiment to mix solid sugar into warm water until it completely dissolves. They record the initial masses in the table below.

Using mathematical thinking, what is the best prediction for the total mass of the mixture, and why?

• 150 grams, because the sugar disappears when it dissolves in the water.

• 175 grams, because matter is conserved even though the sugar is no longer visible.

• Less than 175 grams, because some of the sugar evaporates into the air.

• 200 grams, because dissolving creates new matter.

Analyze the food web model provided. If a sudden disease causes the rabbit population to severely decrease, how will this most likely affect the other populations in the ecosystem?

• The grass population will increase, and the hawk population will have to rely more on mice and snakes.
• The grass population will decrease because there are fewer rabbits to spread its seeds.
• The snake population will increase because they have less competition from rabbits.
• The hawk population will immediately die out.

A student analyzes data showing the average shadows cast by a meter stick at noon over a year.

Which explanation best uses this model to describe Earth's movement?

• The data shows the Sun moves closer to Earth in June and farther away in December.

• The data shows Earth spins on its axis faster in the winter than in the summer.

• The data shows Earth's tilted axis changes the angle of sunlight throughout its yearly orbit around the Sun.

• The data shows the meter stick shrinks and expands depending on the seasonal temperature.

A scientist collects data on two groups of identical plants after two weeks in different conditions.
Which statement best explains these results?

• Plants get all their energy from soil; Group B must have had bad soil.

• Plants use energy from light to make their own food for growth; without light, Group B could not produce food.

• Plants do not need light to survive; the pale color is an inherited trait.

• The dark room caused the water to evaporate too quickly for Group B to grow.

A student releases a toy car down a ramp covered with different materials and records the time it takes to reach the bottom.
Which explanation best interprets this data?

• Ice has the highest amount of gravity, pulling the car down the fastest.

• Wood exerts the most magnetic force on the car.

• Sandpaper exerts the most friction on the car, slowing its speed the most.

• The mass of the car changes depending on the surface it is touching.

Using computational thinking, a student analyzes rainfall data for a coastal city and an inland city at the same latitude.
Which model best explains this difference?

• Inland cities are closer to the sun, causing rain to evaporate before hitting the ground.
• The ocean blocks rain clouds from moving inland, trapping all the rain on the coast.
• Coastal cities have more mountains that produce rain.
• Oceans provide a major source of water vapor; winds carry this moisture to nearby coastal areas, increasing precipitation.

A dog breeder analyzes trait data from three generations of dogs.
Which explanation accurately distinguishes between inherited and acquired traits based on this data?

• The injured tail is an inherited trait that skipped a generation.
• All traits observed in the dogs, including the injured tail, are inherited from the environment.
• Fur color and length are inherited traits passed from parents to offspring, but the injured tail is an acquired trait that is not passed down.
• The long tails on the puppies are an acquired trait learned from the mother.

Look at the model of a simple circuit containing a battery, a switch, and a lightbulb connected by wires. The switch is currently OPEN. Which statement explains what will happen according to the model?

• The bulb will light up because the battery still has chemical energy stored inside.

• The bulb will not light because the open switch breaks the continuous loop needed for electrical energy to transfer.

• The bulb will light up but only at half brightness because the energy can only travel halfway.

• The battery will overheat because the energy has nowhere to go.

A student interprets a model of the human body. They note that the respiratory system brings in oxygen and removes carbon dioxide, while the circulatory system uses the heart to pump blood. Which explanation best describes how these systems interact?

• The respiratory system provides oxygen to the blood, and the circulatory system delivers that oxygen-rich blood to all cells in the body.
• The circulatory system digests food to give energy to the respiratory system.
• The respiratory system controls the beating of the heart using electrical signals.
• The two systems work completely independently to keep the organism alive.

A student analyzes a model of the Earth and the Sun to explain why stars appear to move across the night sky. Which statement correctly explains this phenomenon using the model?

• The stars are attached to a sphere that rotates around the Earth once a day.

• The stars appear to move from east to west because the Earth rotates on its axis from west to east.

• The Earth revolves around the Sun every night, making different stars visible.

• The stars physically travel through space past the Earth each night.
