100
This is the number of stars in our solar system.
What is One? (The Sun)
100
This physical property can be described as a measure of the amount of matter in an object.
What is mass?
100
These are properties that can be measured or observed only when matter undergoes a change to become an entirely different kind of matter.
What are chemical properties?
100
The vertical columns on the periodic table.
What are groups?
100
This is an educated guess during the scientific method.
What is a hypothesis?
200
These objects can be classified as a celestial body resembling a small planet but lacking certain technical criteria that are required for it to be classed as such.
What are dwarf planets?
200
This physical property of matter is described as a measure of the compactness of a substance, expressed as its mass per unit volume.
What is density?
200
This image is an example of what chemical property?
What is rust?
200
The horizontal rows on the periodic table.
What are periods?
200
This is the first step in the scientific method.
What is "make an observation"?
300
These celestial objects consist of a nucleus of ice and dust and, when near the sun, a “tail” of gas and dust particles pointing away from the sun.
What are comets?
300
This is the formula for how to calculate for the density of an object.
What is D=M/V (Density=Mass/Volume)?
300
This chemical property is is the ability of matter to burn.
What is flammability?
300
The atomic number of an element tells us this about an atom of that element
What is number of protons?
300
This is usually written as an "if..., then...." statement.
What is a hypothesis?
400
This is a theoretical spherical layer of icy objects surrounding our Sun, a star, and likely occupies space at a distance between about 2,000 and 100,000 astronomical units (AU) from the Sun.
What is the Oort Cloud?
400
This physical property is the amount of space that an object takes up.
What is volume?
400
This chemical property is the amount or degree in which a substance is needed to be poisonous.
What is toxicity?
400
All of the elements in group 1 on the periodic table have this many number of valence electrons.
What is one?
400
This is the variable that you change during an experiment.
What is the independent variable?
500
We get the term AU (Astronomical mass unit) from this general distance of measurement.
What is the distance between the Earth and the Sun?
500
This is how you can find the volume of an irregular shaped object.
What is water displacement?
500
This chemical property is the ability of matter to combine chemically with other substances.
What is reactivity?
500
When an atom has a different number of neutrons.
What are isotopes?
500
This is the variable that changes during your experiment/is being measured.
What is the dependent variable?
