100
Give an example of a physical property.
What is texture, color or state of matter.
100
What is mass?
What is the measure of the amount of matter in an object.
100
What is the basic particle of an element?
What is the atom.
100
What is a pure substance that cannot be broken down into anything else.
What is an element.
100
What are the three states of matter?
What is solid, liquid and gas.
200
Give an example of a chemical property.
What is the ability to burn, rust or tarnish.
200
What is weight?
What is the measure of the force of gravity on an object.
200
What particles make up an atom?
What is protons, neutrons and electrons.
200
What is made up of two or more elements chemically combined in a set ratio?
What is compound.
200
What system of units do scientists use to measure the properties of matter?
What is metric system.
300
What is a physical change?
What is a change where the substance is still the same substance after the change.
300
Why do scientists use the term mass instead of weight?
What is mass doesn't change and weight does.
300
What charges do the particles carry, electrons, neutrons and protons?
What is electrons=negative, protons=positive and neutrons=neutral.
300
What is a substance with two or more elements, compounds or both that are in the same place but not chemically combined?
What is a mixture.
300
What is water displacement?
What is a method for finding the volume of an odd shaped object. You measure a specific amount of liquid in a graduated cylinder, place the object in the liquid and the difference between your starting volume and your ending volume is the volume of the object.
400
What is a chemical change?
What is a change that occurs when a new substance is created.
400
What is the density of an object with a mass of 180 grams and a volume of 30 cubic centimeters?
What is 6 g/cm3
400
What part of the atom makes up most of the mass?
What is protons and neutrons (the nucleus).
400
What is a heterogeneous mixture.
What is a mixture where you can see the separate parts. Example: Salad
400
What is the volume of a cube with the length of 15 cm, a width of 2 cm and a height of 3 cm?
What is 90 cm3 (cubic centimeters)
500
Melting ice is a physical change. Heating table sugar until it becomes caramel is a chemical change. Compare and contrast the two types of changes.
What is they are both going through a type of change. The difference is that the melted ice is still the same substance where as the caramel is a new substance.
500
Why does a kilogram of sand take up less space than kilogram of feathers?
What is the sand is more dense than the feathers. The particles of sand are tightly packed giving it a larger mass and a smaller volume. The feathers particles are loosely packed giving it a smaller mass in a larger volume.
500
Draw a diagram of an atom and label all the parts. Protons, neutrons, electrons, nucleus and electron cloud.
What is look at white board.
500
What is a homogeneous mixture and give an example of one.
What is a mixture where you can not see the separate parts. Examples: salt water, solutions, coffee, tea
500
If I have two liquids (corn syrup and water) both having the same mass of 10 grams. The corn syrup having a volume of 2 mL and the water having a volume of 10 mL, what are their densities and how would they stack in a graduated cylinder? Which would be on top and which would be on the bottom?
What is corn syrup density: 5 g/mL water density: 1 g/mL The water would be on top of the corn syrup because it is less dense.
