A teacher sets up an experiment using five jars. The teacher keeps one jar unwrapped, and the other four jars are wrapped with equal thicknesses of four different materials. Which property of the materials wrapping the jars are the students most likely investigating? (5.5A)
State of matter
Thermal energy insulation
Thermal energy production
Ability to conduct electricity
Objects that blow into a swimming pool or that are dropped into the pool by swimmers need to be removed. These objects include foam cups, keys, and coins. Which of the following explains a useful method for removing some of these objects? (5.5A)
The keys and coins are less dense than water, so they can be easily picked up off the bottom of the pool by divers.
The foam cups have the same density as water, so they can crumbled up for removal by the pool filter.
The foam cups are less dense than water, so they can be removed from the surface with a pool cleaning net.
The keys and coins have the same density as water, so they can washed away when the pool is drained.
A cook uses the ingredients listed to prepare a meal. Which table correctly show the physical properties of these ingredients when placed in hot water? (5.5A)
Some students investigate the properties of four objects using a hand lens, a magnet, and a beaker containing water. Their observations are recorded in the table. Which statement identifies a property that could be used to classify these objects into two different groups? (5.5A)
Density can be used to separate objects that sink in water from objects that do not.
Magnetism can be used to separate objects that are attracted by a magnet from objects that are not.
Solubility can be used to separate objects that dissolve in water from objects that do not.
Physical state can be used to separate objects that are solids from objects that are not.
A student made observations about several substances when mixed with water. Her observations are recorded in the chart shown. Which substances proved to be insoluble?
Substances S and U
Substances T, U & V
Only Substance T
Substances S, U, V
A student needs to separate a mixture. He notes that some of the items are less dense than water while other items are more dense. What would be the best way to separate the items using relative density?
Use a magnet to remove the items that are more dense.
Use a hotplate to evaporate the items that are less dense.
Add water to see which items dissolve.
Add water to separate the less dense items first.
Check all of the phrases below that represent physical properties.

A student has a graduated cylinder with different substances of different densities. If the student adds more oil, to the graduated cylinder, what would be the most likely result?
The volume of the oil will decrease
The volume of all the substances will increase
The volume of the oil will increase
The volume of all the substances will decrease.
