Metric System
This metric unit would be a reasonable choice for measuring the length of your classroom.
What is a meter?
This is the basic building block of matter.
What is an atom?
A substance made of only one type of atom.
What is an element?
This is the substance that gets dissolved when making a solution.
What is the solute?
This term describes how much solute is present in a given amount of solution.
What is concentration?
This metric unit would be appropriate for measuring a very long distance.
What is a kilometer?
These two subatomic particles are found in the nucleus.
What are protons and neutrons?
Two or more atoms chemically bonded together.
What is a molecule?
This is the substance that does the dissolving.
What is the solvent?
If more water is added to Kool-Aid without adding more powder, the concentration does this.
What is decreases?
This is the number of centimeters in one meter.
What is 100 centimeters?
I am outside the nucleus, and my charge is the opposite of a proton's. I am this particle.
What is an electron?
Two or more different elements chemically bonded together.
What is a compound?
This is the mixture formed when a solute dissolves in a solvent.
What is a solution?
Cup A has 1 scoop of drink mix + 1 cup water. Cup B has 3 scoops + 1 cup water. This cup is more concentrated.
What is Cup B?
This is 500 centimeters converted into meters.
What is 5 meters?
Name the charge AND location of a neutron.
What are neutral (or no charge) and in the nucleus?
Two or more substances that are physically combined but are not chemically bonded.
What is a mixture?
In koolaid, this substance is the solvent.
What is water?
A solution contains 20 g of solute and 80 g of solvent. This is the total mass of the solution.
What is 100 g?
Put these units in order from smallest to largest: kilometer, millimeter, meter, centimeter.
What are millimeter, centimeter, meter, kilometer?
Name all three subatomic particles, their charges, AND whether they are inside or outside the nucleus.
What are:
Proton—positive, nucleus
Neutron—neutral, nucleus
Electron—negative, outside the nucleus?
Substance A: Contains two different types of atoms chemically bonded together.
Substance B: contains two different types of particles that are not chemically bonded.
These are the classifications of Substance A and Substance B.
What are a compound and a mixture?
A student mixes sugar completely into water. Name all three:
The solute, the solvent, and the solution.
What are:
sugar = solute
water = solvent
sugar water = solution?
A solution contains 30 g of solute and 120 g of water. This is its percent concentration.
What is 20%?
