matter term for anything that takes up space and has mass
particles the small bits of material that make up matter
liquid matter that has definite volume and takes the shape of its container
gas matter that has no definite shape and takes up no definite amount of space
solid matter that has definite volume and shape
Adding Heat They start moving faster!!!! Adding heat makes the particles act differently!

volume amount of space that matter takes up
VolumeVolume is the amount of space that matter takes up. The volume of something can be measured using math and a graduated cylinder, a ruler, or a tape measure. volume = Length X Width X Height
Think about these two methods for calculating a solid’s volume. Which one would be used to find the volume of... volume = Length X Width X Height This one because it is a nice, straight shape that can easily be measured with a ruler. This method is better because it is an irregular shape.
Look at these containers. One is filled with cotton balls and one is filled with white sand. Do they have the same volume? Yes!!!! Since both containers are the same size, they both take up the exact same amount of space, so they have the exact same volume! With volume, it doesn’t matter how heavy the matter is! white sand cotton balls
Look at these cups! Compare their mass and their volume. They both have the same volume because they are both the same container. However, their masses are different. Mashed potatoes would be heavier than Rice Krispies! mashed potatoes rice Krispies
mass amount of matter something contains
MassMass is the amount of matter something contains. The mass of something can be measured using a triple beam balance.
Think about the mass of these objects. Put them in order from least to most in your mind. Then click to check.
Look at these containers. One is filled with cotton balls and one is filled with white sand. Do they have the same mass? No!!!! They have the same volume, but not the same mass. White sand has a lot more matter than cotton balls, therefore, it is heavier, and has more mass! white sand cotton balls
density compares an amount of matter to the amount of space it takes up
Density compares the volume of something to the mass of something! WHITE SAND IS MORE DENSE!!! Mass: 100 grams Volume: 136 cubic centimeters Mass: 200 grams Volume: 136 cubic centimeters white sand cotton balls Density= mass divided by volume! 200/136= 1.47 Density= mass divided by volume! 100/136= .74
What conclusion could you draw about density from this information? Each measuring cup is filled with a certain food. It’s mass is given. The chips are the least dense. The mashed potatoes are the most dense, and the Rice Krispies are in between. mashed potatoes 216 g. Chips 83 g. Rice Krispies 104 g.
If you wanted to measure the density of these items, which tools would you use? length X width X height
If you wanted to measure the density of these items, which tools would you use? length X width X height
If you wanted to measure the density of these items, which tools would you use? length X width X height
buoyancy ability of matter to float in a liquid of gas
The less dense an object is, the more buoyant it is! Which of these items do you think is buoyant? Bobbers float on water when you’re fishing! Wood also floats! That’s why boats are made of wood!
Solution forms when different particles of matter mix evenly inliquid
If I mixed these together, would it be a solution? YES! You could NOT un-mix it!
If I mixed these together, would it be a solution? NO! You could un-mix it using your hands or a magnet!
If I mixed these together, would it be a solution? YES! You could NOT un-mix it!
If I mixed these together, would it be a solution? NO! You could un-mix it using your hands or a filter!
solubility measures the amount of one material that will dissolve in another material
dissolves what happens when one material forms a solution with another material
Some things dissolve easily in water!Which ones do you think? I tricked you! Ice doesn’t dissolve, it melts! Plus, ice is the same thing as water, so it’s not a different material. Chocolate will dissolve, but not as easily as sugar! Leaves won’t dissolve. Salt will dissolve, but not as easily as sugar! Sugar dissolves VERY easily– especially in warm water!
