Vocabulary
This term means anything that has mass and takes up space.
What is matter?
If an object can be bent without breaking, it has this property.
What is flexibility?
This tool is used to measure mass.
What is a triple bean balance?
This is when two or more substances are mixed but not chemically combined.
What is a mixture?
This tool separates solids from liquids using a screen.
What is a filter?
This word describes how something feels or looks, like smooth or rough.
What is texture?
This property explains why some objects are pulled by magnets.
What is magnetism?
This unit is commonly used to measure volume of liquids.
What is milliliters (mL)?
This type of mixture is evenly mixed and looks the same throughout.
What is a solution?
This method separates materials using a magnet.
What is magnetic separation?
This is the amount of space liquid inside an object takes up.
What is volume?
This property helps determine whether an object will sink or float in water.
What is density?
This tool is used to measure the volume of a liquid accurately.
👉 What is a graduated cylinder?
In a solution, this is the substance that gets dissolved.
What is the solute?
This method uses evaporation to separate a dissolved solid from a liquid.
What is evaporation?
This word describes matter that cannot be seen through.
What is opaque?
An object has a lot of mass packed into a small space, causing it to sink in water.
What is high density? (More dense)
(DO THE MATH)
A student measures the volume of water in a graduated cylinder at 50 mL. After placing a rock into the cylinder, the water level rises to 68 mL. The student records the volume of the rock.
What is 18 milliliters?
This is the substance that does the dissolving.
What is the solvent?
This tool or method separates particles based on size using holes or mesh.
What is a strainer (or a sieve)?
This is when matter changes into a new substance with new properties.
What is a chemical change?
A student notices a substance bubbling and changing color when mixed with another substance. This shows a change where a new substance is formed.
What is a chemical change?
A student measures the mass of an object and its volume using water displacement, then divides the two values to compare substances. What measurement are they finding?
What is density?
student mixes sugar and water until the sugar completely disappears. The mixture looks the same throughout and cannot be easily separated.
What is a solution
A mixture of sand, salt, and iron filings needs to be completely separated. The student first removes the iron, then separates the sand from the saltwater, and finally recovers the salt.
What is using magnetic separation, filtration, and evaporation?
