An idea that can be replicated, verified, and can be observed and tested is known as a what?
What is a scientific idea?
What does mass measure?
What is the quantity of matter in an object?
Density is...
What is the amount of mass per volume?
The temperature when liquid turns to gas.
What is boiling point?
The rearrangement of atoms by breaking and reforming bonds.
What is a chemical reaction?
A statement that is biased in its results and ignores parts of the method within an investigation is known as a what?
What is a pseudoscientific idea?
What does weight measure?
What is the force of gravity acting on an object?
The formula for calculating density.
What is mass/volume?
The materials ability to dissolve.
What is solubility?
When baking soda and vinegar react, the surface bubbles indicating that this is happening because this new substance is being formed.
What is a chemical reaction because a gas is being formed?
Which of the following does science attempt to explain? Moral values, Biased opinion, meaning of life, or natural phenomenon?
What is natural phenomenon?
The gravitational strength at the poles is greater than the gravitational strength at the equator. What will happen to an object when it moves from the poles to the equator?
What is its weight will decrease?
Object A has a mass of 10 g and a volume of 8 cm3. Object B has a mass of 10 g and a volume of 6 cm3. The object with a greater density.
What is Object B, by 0.42 gram per cubic centimeter?
Magnetism is this type of physical property because it does not depend on how much matter is present.
What is an intensive physical property?
The difference between an endothermic and exothermic reaction.
What is energy is needed for an endothermic reaction to take place but energy is released in an exothermic reaction?
What is the typical, common sense order of the scientific method?
What is the purpose/question, research, hypothesis/proposed explanation, experiment, analysis, conclusion?
Two descriptions about physical quantities are given below:
Quantity A: It remains constant.
Quantity B: It depends on gravitational pull.
What quantities are these most likely describing?
What is Quantity A is mass and Quantity B is weight?
Object A has a density of 10 g/cm3 and a mass of 9 g. Object B has a density of 10 g/cm3 and a mass of 4 g. The object with the greater volume.
What is Object A, by 0.5 cubic centimeter?
Read the list of substances.
Wood, Iron, Glass, Aluminum, Paper
Substances that have high thermal conductivity.
What is Iron and Aluminum.
A reason that a substance may have less mass after the chemical reaction.
What is because some of the product escaped into the air as a gas?
Micah is studying the effect of soil on the growth of plants. Three identical plants having a height of 15 cm were used for the experiment. The first plant was planted in Type A soil in 4 hours of sunlight, the second plant was planted in Type B soil in 6 hours of sunlight, and the third plant was planted in Type C soil in darkness. All other growing conditions of the plants were kept constant. What did Micah do wrong?
What is control the amount of sun that each plant received?
The gravitational strength on Earth is less than the gravitational strength on Neptune. The weight will be greater on this planet.
What is the weight of an object will be greater on Neptune than Earth?
The properties of a cube are listed below:
Density = 40 g/cm3
Length of side = 2 cm
The mass of the cube.
What is 320 grams?
Read the list of substances.
Air, Copper, Glass, Gold, Wood
The substances that have high electrical conductivity.
What is the Copper and Gold?
A reason why the mass of the products might be more than the reactants.
What is because a gas from the air reacted with one of the other reactants?
