100
These are the building blocks of matter
What are elements
100
This is the smallest particle of an element with properties of that element.
What is an atom
100
These are the three phases of matter and these are what the temperatures at which the phases change from one to another are called.
What are solid, liquid, and gas. What is solid to liquid - melting point, liquid to solid - freezing point, liquid to gas - boiling point.
100
This is how elements are held together in compounds and this is how they are held together in mixtures.
What is elements are bonded together in compounds but they are mixed in but not bonded together in mixtures.
100
This is the density of an object which has a mass of 100 grams and occupies a volume of 50cc.
What is 100/50 = 2 grams/cc
200
This is how density is measured in metric units and this is how it is compared to buoyancy.
What is divide mass in grams by volume in cubic centimeters and whether a material floats in a liquid determines whether it is buoyant or not. Material with density less than the liquid's density will be floating (buoyant) and density more than the liquid's density will sink. Buoyancy depends on the density of the material and liquid
200
This is the particle in the atom's center with no charge, this is the particle in the center with positive charge, and this is the particle in the atom with negative charge.
What is neutron, proton, and electron.
200
This is what happens when materials undergo changes in temperature. This is what happens when materials cool and this is what happens when materials heat up.
What is materials change size. Particles become slower and space between particles become less and materials get smaller when cooled. Particles move faster and more space between particles lead to materials becoming larger when heated up.
200
This is what happens to elements when a compound is formed and this is what happens when a mixture is formed.
What is elements change their properties when they form compounds and they retain their own properties when mixtures are formed.
200
This is an example of a simple mixture. This is what a mixture of solid elements/metals is called. This is an example of a mixture of solid elements.
What is salt and pepper (can be separated easily). What is an alloy. Steel (mixture of iron and carbon), Brass (mixture of copper and zinc)
300
This is the measure of the pull of gravity on an object, this is the amount of matter contained in an object, and this is the amount of space occupied by an object.
What is weight, mass, and volume.
300
This is the type of matter made of more than one element and this is the smallest part of this matter.
What is a compound and what is the molecule.
300
This is what happens when clouds in the sky and dew on the ground is formed.
What is condensation. Condensation happens when gas turns to liquid. Gas particles cool down and slow down. The cold objects attract and trap more gas particles and form drops of liquid. Water vapor cools down and condenses to form clouds and dew.
300
This is what forms when the materials in a mixture are distributed evenly. This is what the material that spreads out is called and this is what the material in which the substance dissolves is called. This is an example.
What is a solution. What is a solute and what is a solvent. Mixing salt and water forms a salt solution, the salt is the solute and water is the solvent.
300
These are the similarities between mixtures and solutions.
What is the elements or compounds are mixed together but not bonded. Mixtures are where different materials come together but do not form compounds and retain the properties of each component material.
400
This is how you measure the volume of a solid cube and this is how you measure the volume of a liquid
What is measure and multiply the length, width, and height of the cube and what is measure the liquid in a graduated cylinder.
400
The formula for a water molecule is H2O. This is the number of elements it has and this is the number of atoms of each element it has.
What is 2 elements with 2 atoms of hydrogen and 1 atom of oxygen
400
This is what happens when liquid changes to gas. These are the two phase change temperatures that are the same.
What is evaporation. Freezing point and melting point are the same temperature.
400
This is the type of solution where no more solute can be dissolved in the solvent without changing the temperature.
What is a saturated solution.
400
These are the differences between mixtures and solutions.
What is the simple mixtures can be easily separated. Solutions are special kinds of mixtures where the substances are evenly spread out and will not settle. In a solution, the solute is dissolved in a solvent and the solubility (amount of solute dissolved) is a property of the substance.
500
This is how you compare the density of pure silver in the form of jewelery and pure silver in the form of a coin.
What is the density remains the same no matter what the silver is used in as long as it is pure.
500
This is a type of compound formed where molecules are held together by opposite charges and this is what the regular geometric pattern it forms is called.
What is a salt and it forms crystals.
500
This is what happens to the freezing point and boiling point of water when another material like salt is added.
What is the freezing point will lower and the boiling point will elevate (become higher).
500
This is the type of solution where there is a lot of solute and the solution is nearing saturation, and this is the type of solution where there is very little solute and far from saturation.
What is a concentrated solution and a dilute solution.
500
These are the elements that are most similar to Carbon (C) in the periodic table.
What are Silicon (Si), Germanium (Ge), Tin (Sn), Lead (Pb) - same group.
