5th Grade RP3 Benchmark Practice

A cracker weighed 200 g.  The cracker is broken into 4 even pieces, then into 8 pieces. The cracker is then weighed again, ensuring that every piece of the cracker is on the scale. A student decides to graph the weight after each break. 

Which graph best shows the mass of the cracker over the time?

• 
• 
• 
• 

Marina is trying to make a model that shows Terrance that even though the water was no longer in the pot, it was not destroyed. She wants to show the principle of Conservation of Mass. Which model should she use to help Terrance understand that matter isn't destroyed when it changes?

• Water evaporating from a puddle

• burning a log into ash

• mixing oil and water

• weighing a piece of paper, ripping the piece of paper into many pieces and weighing it again

In 2011 Hurricane Irene caused severe damage to houses, beaches and cities in New Jersey. The hurricane's wind and heavy rain created large powerful waves that caused erosion to the beaches.

People living in a Ocean City want to protect their beach from a hurricane that is headed their way in one week.. They have collected $1000 for project supplies.

Which of the following best describes the problem for their project?

• We need to fix the beach in one week

• We will use the $1000 to buy sand and pile it on the beach to protect the shoreline from erosion

• We need to learn more about hurricanes and beach erosion

• We need to design a solution to beach erosion in One week and using only $1000

On a nature walk by Cooper River, JC noticed that several dead fish washed up on the river bank. He researched this problem, and learned that a New Housing development was being built across from the river. He concluded that this housing project may be polluting the water.

JC wants to design a filter that can catch the pollutants before they wash into the river.

Which of the following is an example of criteria he might use in developing this design?

• The filter design should be tested many times.

• The filter must collect a large amount of pollutants before it gets to the river.

• The filter can only be built with materials in JC's house

• The filter can only cost around $30

Water is constantly recycled through many different processes on Earth, called the water cycle. This process allows for freshwater to be recycled for human use. Human's rely on freshwater for drinking, and it is a very limited resources. 

Which of the following statements describe paths that water can take that add to our supply of fresh water? SELECT ALL THAT APPLY.

• Snow falls on the top of a mountain, freezes and becomes a glacier 

• Rain water runs off the ground and into streams and rivers into a local lake or pond

• Rain falls to the ground and seeps into the ground into a groundwater reservoir well

• River water flows through streams and rivers ending up in the ocean.

JC creates an initial design for his filter, He placed the filter in a drain that flows from the Housing development to the river. He collected data and found that his design help keep the water clean, but it was harmful to the turtles. 

What should JC do next? 

• Start from scratch, redesign the whole filter

• Place the filter in every drain that flows to cooper river.

• Collect more data about how the filter affects the biosphere and make improvements.

• Collect more data about how the filter affects the hydrosphere and make improvements.

Said poured 5 cups of water in an bowl two weeks ago and placed it in the freezer. He took the ibowl out of the freezer yesterday and accidentally left it on the counter while he was at school. When he returned home from school, the ice had melting in the bowl.

Said measured the amount of water that came from the melted ice. Which should be the amount of water that is in the bowl?

• 7 cups

• 5 cups

• 4 cups

• 6 cups

John wants to create a model that explains the rain shadow effect. He wants to make sure he has the steps in the correct order 

Label the events below from 1 to 4.

What is the FIRST STEP in the rain formation process?

• Clouds fall lower in the atmosphere on the other side of the mountain and carry small liquid water droplets over land. 

• Clouds are redirected higher in the atmosphere by mountains produce rain. 

• Water warms and evaporates into the air. 

• As the water vapor rises in the air, it cools and condenses to form clouds.
