Some student put ice cubes on separate plates.  One ice cube has a mass of 40 grams, the other has a mass of 80 grams.  Which result would be the SAME for each ice cube in this investigation?

• the time it took each ice cube to melt
• the temperature at which each ice cube melted
• the amount of liquid produced on each plate
• the total volume of each ice cube

The picture shows the view of the ball from above the table.  The ball is rolling across the table.  A student lightly taps the ball in the direction shown in the picture.  In what direction does the ball most likely move after the student taps it?

• Up
• Up and to the right
• Down
• Same direction

One of the brightest objects in the night sky is a planet that is closer to the Sun than Earth is.  What is the name of this planet?

• Mars
• Jupiter
• Venus
• Neptune

A student conducts and investigation using four identical cans, each with a hole in the bottom.  The student fills each can with a different type of soil and then adds 200 ml of water.  The graduated cylinders in the picture show how much water is drains through the soil and out the bottom of each can.  Which soil would stop water from reaching to the deepest parts of a plants roots? 

• Soil 1
• Soil 2
• Soil 3
• Soil 4

A student studies two maps of Texas that shows the high temperatures for two days in October 2012.  How many degrees Celsius did the high temperature increase in the city that had the greatest change in high temperature? 

• 5 Degrees Celsius
• 1 Degree Celsius
• 0 Degrees Celcius
• 3 Degrees Celcius

A picture of the water cycle is shown.  Which of these observations would most likely be seen at Stage N? 

• Water flowing downhill
• Fog forming along the highway
• Water level of the lake decreasing
• Dark clouds forming in the sky

The graph shows the length of a shadow of a tree during part of the day.  If the day continues to be sunny, what will most likely happen to the length of the shadow from 2 P.M. to 4 P.M.?

• The length of the shadow will stay the same
• The length of the shadow will decrease then increase
• The length of the shadow will increase
• The length of the shadow will decrease

A teacher mixes a white powder into a beaker of water.  The powder cannot be seen in the water.  The teacher then heats the mixture until all the water evaporates and the powder can be seen again.  Which property of the powder is the teacher demonstrating?

• Solubility
• Density
• Conductivity
• Mass

A student uses a spring scale to  pull a 50-gram block horizontally across a wood desk.  Then the student pulls the block the same distance across the surfaces of carpet, sandpaper, and glass.  Which question is the investigation most likely designed to answer?

• How do blocks of different sizes react to force?
• How do different surfaces affect the amount of force needed to move a block?
• How do blocks affect spring scales?
• How does the mass of a block change when its pulled across a desk?

A student classifies the objects shown based on their physical properties.  Which property CANNOT be used to classify these objects into more than one group?

• Magnetism
• Mass
• Electrical conductivity
• Solubility in water
