Which column headings should the students use for their table?

• 
• 
• 
• 

The table lists some physical properties of two objects...

Based on their properties, which of the objects is most likely a metal?

• Object 1, because it is a solid that is less dense than water

• Object 2, because all metals float in water

• Object 2, because metals conduct thermal energy and electricity

• Object 1, because it can be used to provide insulation for thermal energy

Yohana stirs 15 grams of each substance listed below into 200 milliliters of water to form four different mixtures. Yohana then tries to separate the water from each mixture by pouring the mixture through a kitchen tea strainer. Which mixture can Yohana separate most easily with the strainer?

• Salt and water

• Gravel and water

• Shampoo and water

• Sugar and water

A student places 250 g samples of clay, sand, gravel, and silt in separate flower pots. The pots are set on a wire rack, and dishes are placed beneath the pots so that water can drip through holes and collect. The student then pours 100 mL of water over the sample in each pot. The student measures the time it takes for water to begin dripping from the bottom of each pot.What property of soils is the student most likely examining with this procedure?

• The amount of time it takes different soils to dry

• How well different soils retain water

• How much water is needed to dissolve different soils

• The differences in texture between wet and dry soils

A student helped his father prepare soup for dinner. His father asked him to use a wooden spoon to stir the soup as it heated.

Why would the student's father ask him to use a wooden spoon?

• The wooden spoon is able to float in the soup

• the wooden spoon is able to sink in the soup

• the wooden spoon is a good conductor of thermal energy

• The wooden spoon is a good insulator of thermal energy
