A group of students have a block of aluminum 10cm by 10cm by 10cm. They conducted some tests and records their results. The students found a smaller block of aluminum that is only 1cm by 1cm by 1cm. Which property do we expect to observe in the smaller block? The smaller block will-

• Have a mass of 2.8kg

• Float in water

• Conduct electricity

• Be attracted to a magnet

Students filled a graduated cylinder with water and oil. Next they placed two samples, Substance X and Substance Y, in the same graduated cylinder. The illustration shows the final positions of all these materials. What conclusion can be drawn from this observation?

• Water is less dense than oil

• Substance Y is less dense than oil

• Oil is more dense than water

• Substance X is less dense than water

The table lists some properties of three labeled objects. Based on their properties, which of these tables properly identifies the objects?

• 
• 
• 
• 

A team of students listed the properties of two mystery substances for another team to identify. Based on their properties, which of the objects is most likely aluminum?

• Substance Y, because aluminum is always a solid

• Substance Z, because aluminum is a thermal insulator

• Substance Y, because aluminum is a good thermal conductor

• Substance Z, because aluminum always floats in water
