Based on this data chart, which statement correctly describes one of the materials?
Tap to reveal answer
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.

A physical change is a change is a substance that does not change what the substance is. In contrast, in chemical change a new substance is formed.
Let's look at our options:
When wood is burned, the wood turns into ash. We can't get the piece of wood back once it's been burned; thus, wood burning is a chemical change.
When a cake is baked, the ingredients combine and turn into a cake once it's baked. Once we have a cake, we can't get the ingredients back; thus, baking a cake is a chemical change.
When a nail rusts, pieces of the metal nail have turned into rust. We can't get the original nail back; thus, a nail rusting is a chemical change.
Ice is made up of water, and when the ice melts we are left with a puddle of water. If we freeze the water, it will turn back into ice; thus, melting ice is a physical change.

Which of the physical properties listed below can be measured?
Which of the physical properties listed below can be measured?
Tap to reveal answer
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.

The answer is "all of these."
A substance is anything that takes up space and has mass. Substances can exist in solid, liquid, and gas form. When you mix two substances and you might or might not create something new, and it all depends on what two substances you are mixing. Ripping, tearing, smashing, stirring, squishing, and changing the shape of a substance by mixing it with another is called a physical change. Chemical changes occur when a new, third substance is created by combining two substances. Signs of a chemical change include, release of heat, bubbles, a color change, and smells!

A mixture is when two or more substances are combined to create something new. The substances can remain separate like a salad or trail mix, but still, something new is formed. Another type of mixture is a solution when one substance dissolves into another like salt being stirred into water.

Many people have the misconception that once a substance has been mixed into a liquid that it cannot be separated. When something like salt is stirred into water, it seems to disappear, so the thought of separating it can be hard to imagine. There is no way to sift the salt out or remove the salt pieces with forceps. If the water is set in the sunlight, it will begin to evaporate and leave behind the salt that was mixed in.

The answer is Monica because she is moving more matter (tiny particles) into a balloon and even though we cannot see them, we can see how the balloon gets larger. Deontay is correct that he could keep breaking things apart, but he has a hypothesis and is not conducting an experiment or a demonstration. Celeste's project is about photosynthesis.
Matter is anything that takes up space. Matter is in the form of solid, liquid, or gas. Solids, liquids, and gases are made of tiny particles called atoms and molecules. In a solid, the particles are very attracted to each other. They are close together and vibrate in position but don’t move past one another. In a liquid, the particles are attracted to each other but not as much as they are in a solid. The particles of a liquid are close together, always moving, and can slide past one another. In a gas, the particles have very little attraction to each other. They are very far apart compared to the particles in a solid or liquid, and are constantly moving. The particles don’t interact with one another but just hit and bounce off of each other when they collide.

Electrons have a negative charge. The proton moves around the nucleus of an atom, which is in the center. The charge of an electron is opposite but equal to the charge of a proton. Atoms have the same number of electrons as protons. We cannot see these with our eyes, and even with a high-powered microscope, they are too tiny and too low in mass to see.
