Identifying Material Properties - 5th Grade Science

The answer is "-30 degrees Fahrenheit"

Standard units are used to measure and describe physical quantities such as weight, time, temperature, and volume. The standard unit for temperature is degrees Fahrenheit. Volume is measured in Liters, weight in pounds, and time is measured in minutes, seconds, or hours.

The answer is liquid number 2. Density is a measure of the amount of "stuff" in a given volume. More dense objects sink and less dense objects float.

The answer is 45 because there are 10 millimeters in a centimeter and the ruler is measuring 4.5 centimeters.

The answer is "at number 3" because you measure volume at the meniscus.

This data table provides observations and measurements of two mystery samples. Properties of materials can be used to determine what objects are or the qualities of them. In this case, we are looking for the property that would allude to these samples being solids instead of liquids, and that property is the shape of the samples. Liquids or solids can be measured for mass and volume and described by color, but cannot be characterized by shape. Liquids take the form of the container that they are in, whereas solids maintain a specific shape. These samples are solids because they are a cube and pyramid.

This data table lists what each student observed when they were looking at their material. Some of the properties that describe this material can be gathered through observation, while others are through measurement. In this case, what type of matter the student is looking at comes down to the shape. A gas, liquid, or solid can be any color, mass, or volume, so those characteristics are less helpful in identifying what these materials are. Gases have no shape, liquids take the form of the containers they are in, and solids have a definite figure. Mildred and Dolly look at solids because the material is described as a pyramid and a sphere, which are definite shapes. Edmund and Betsy look at materials with no shape, which means they are gas or liquid, so the only answer choice that matches is "Betsy observed a liquid.".

The statement "The physical properties of matter can only be gathered through measuring." is false. The physical properties of matter can be gathered through measurement AND observation. Using the five senses to collect information about the material or matter is just as crucial as taking concrete measures like the mass or volume. Classification and categorization of material are best done through a combination of observation and measurement.

All of the physical properties listed below can be determined through measurement. A material's freezing point can be determined by keeping track of the temperature the material is exposed to colder and colder temperatures until it freezes. The temperature this happens is decided after multiple trials determine its freezing point. A material's boiling point is discovered by measuring a rising temperature until the material comes to a rolling boil. Both of these physical properties are measured with a thermometer. Finally, whether a material conducts electricity depends on what the sample is made up of. Things like wood, plastic, and cloth do not conduct electricity well, while metal and copper do. The electrical conductivity can be calculated by measuring the resistance, area, and length of the test material. You can also use a four-terminal ohmmeter for greater accuracy.

The statement "Texture is a physical property that is determined through measurement." is false. Texture cannot be measured with a tool but is a physical property that is gathered using one of the five senses. Our sense of touch allows us to feel materials and make determinations about what we are observing. We would not use a ruler or thermometer to determine a material's texture.

Based on your observation of the liquid, you know a few things to be true:

1. The liquid is clear. Since cola is brown in color and not clear, this eliminates cola.

2. The liquid has an odor. Since water is odorless, this eliminates water.

Given the available answer choices, this means that the liquid COULD be bleach, but of course you haven't proven that, you just haven't eliminated it as a possibility. There are many clear liquids that have an odor, so you can't definitively say it's bleach, but you can rule out odorless or colorful liquids. That's why the answer is that the liquid could be bleach, and cannot be cola or water.

The answer is baking soda. Baking soda is a common household product that is a base. Vinegar is an acid. Acids and bases react chemically when combined.

The answer is "it can be used to make other things." This is not a property of matter. Some common properties of matter are: color, luster (how shiny it is), texture, inertia, mass, weight, volume, density and specific gravity.

The answer is "all of these." This is not a property of matter. Some common properties of matter are: color, luster (how shiny it is), texture, inertia, mass, weight, volume, density and specific gravity.

The answer is a staple, because a staple has all of the properties listed. An ice cube does not exist as a solid at room temperature. A wagon is not 1 cm long and cannot be bent with your hand. A pair of scissors is also not a centimeter long.

Water vapor is a gas, and you may have heard the term when discussing the water cycle or evaporation. When thinking about the three states of matter that can describe a substance, it can be either a solid, liquid, or gas. These can be hot or cold by definition, colorless, light or heavy, but only one ca spread through their air with no definite shape; that is a gas. A gas has no shape and would spread throughout the air; if it is trapped in a container, it will continue to move about the container and not remain stationary.

Two properties that describe both liquids and solids are a definite mass and volume but not a definite shape. The liquid takes the shape of the container it is placed within, while solids have an actual fixed shape. If you put water in a bowl, it will be bowl-shaped. If you put liquid in a bottle, it will be bottle-shaped. If you place an ice cube in these same containers, they will remain an ice cube shape unless they melt into a liquid.

None of the physical properties listed below can be determined through measurement. A material's freezing point can be determined by keeping track of the temperature the material is exposed to colder and colder temperatures until it freezes.

The electrical conductivity can be calculated by measuring the resistance, area, and length of the test material. You can also use a four-terminal ohmmeter for greater accuracy. All of these physical properties require testing and the use of measurement to determine.

The statement "Color is a physical property that is determined through observation." is true. Color cannot be measured with a tool but is a physical property that is gathered using one of the five senses. Our sense of sight allows us to see color and make determinations about what we are observing. We would not use a ruler or thermometer to determine a material's color.
