A student is comparing the properties of 2 pieces of matter.  He has a piece of gold and a piece of silver.  Just by looking at them, the student knows which the gold is and which the silver is.  The student can tell because each of these minerals has a different:

Sally was conducting a simple experiment to determine changes in the properties of matter.  The beaker above contains water.  The other container is empty.  Which property of water would change if she poured all of the water from the beaker into the empty container?

Jon was preforming a science investigation using different kinds of matter, water, and a microscope.  If he looked at a drop of water under a microscope, which material would he be able to see if it was well mixed with water?

James was trying to describe some of the physical characteristics of a piece of matter.  He was using both a hand lens and a microscope.  What physical characteristics of matter can you identify with these two scienctific instruments?

Sand, silt, and clay are tiny particles of rock that are found in soil.  Jane was doing an experiment to determine which of these particles had a longer width.  The results of her experiment are shown in the table above.  Which type of particle would you need a hand lens to see in soil?

Jon had some pieces of metal and was experimenting on how to make a magnet.  He took each piece of metal and rubbed it against a very powerful magnet he had borrowed from his science teacher.  Which of these substances did Jon discover made the most powerful magnet?

Sam was experimenting with toys made of different materials.  He was investigating which toy would attract to a magnet.  Which of the following toys did Sam find attracted a magnet?

The science class was working with compasses to observe the force that their science teacher told them surrounds the Earth.  What force did the class determine makes the compass point North?

Sue’s science class discussed the three states of matter.  They made drawing of the action molecules of matter displayed in each state.  Which of the following states (phases) of matter is characterized by the most energetic molecules?

James and his science class were investigating the properties of metal.  James remembered that metal had many important characteristics.  Which of the following would not be used to describe a metal?

The science class was investigating the properties of metal.  They remembered they had made electrical circuits with copper wire, a battery, and a light bulb.  They discovered that electricity flows freely through a copper and determined that copper wire was an example of a good:

The fifth grade science class was experimenting with the characteristics of water.  They filled a beaker with 40 ml of water and placed it outside their classroom in the sunlight on a hot summer day.  An hour later they notice that almost all the water had evaporated.  What caused the water to change from liquid water to water vapor?

The fifth grade science class placed a pan on a picnic table outside their classroom.  It looked just like the drawing above. That morning it rained and the pan had one centimeter of rainwater in it.  The rest of the day was hot and sunny.  By 3:00 PM, all the rainwater in the pan had disappeared.

What most likely happened to the rainwater in the pan?
 

Charles was determining the mass of an ice cube using a balance scale.  He calculated the mass of the ice cube in the drawing above to be 5.0 kilograms.

If the ice cube melts completely what will be the mass of the water in the tray?

Susan was experimenting with different types of matter to determine the buoyancy of each item.  She mixed oil, sand , and vinegar together in a beaker of water.  Which of the following would you expect to float on water?

Students in science class were discussing the different phases of the water cycle.  They remembered that as water vapor in the air rose high in the sky the air cooled; the water vapor cooled and began to change into water droplets forming clouds.  Because water is made of atoms, a supply of water does not condense all at once.  Instead, what happens when water condenses?

Ben and his classmates were working with the thermometers pictured.  The were investigating the different temperatures of water.  Use the thermometers below to answser questions 17 - 20.
    

On the Fahrenheit scale the boiling point of water is:

On the Celsius scale the boiling point of water is:

On the Celsius scale the freezing and melting point of water is:

On the Fahrenheit scale the freezing and melting point of water is:

A student in the fifth grade science class decided to make a cake for her teacher.  She combined flour, baking powder, and salt in a large bowl and stirred the ingredients.

This combination of ingredients is a:

The science class was working with many different types of mixtures discussed in class.  One group made a mixture and then thought about how they could separate the components that made up the mixture.

Which mixture could be separated into its component parts with a magnet?

The lab for the fifth grade science class will be working with mixtures of matter.  The students plan to mix a different material into each of the beakers pictured above.

Based on the students understanding of mixtures, which material will dissolve in the water?

Separating mixtures into their individual components can be sometimes easily done using a funnel and filter paper.  The picture above shows a funnel with filter paper inside it.  The fifth grade science class will be using these tools in their mixture lab.

Based on the students understanding, which of the following mixtures can be separated using a funnel and filter paper?

In science lab a student mixed together oil and vinegar to make salad dressing.  The student added too much oil and wants to remove some of it from the mixture before adding the rest of the ingredients.  How can the student best remove some of the oil?

The fifth grade science class was investigating the properties of “dry ice”.  They learned that dry ice was really solid carbon dioxide that was kept at very low temperatures.  Students were to try and discover what happens to dry ice when it is exposed to room temperatures.

As the fifth grade science class was learning about the three states of matter they discussed what changes caused a liquid to change into a solid.  Which of these processes best causes that change to happen.
