This is the number of stars in our Solar System
What is one (The sun)
This physical property can be described as a measure of the amount of matter in an object
What is Mass
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
The vertical Columns on the Periodic table are called this
What are groups
This is an educated guess during the Scientific Method
What is a Hypothesis
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
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
This image is an example of what chemical property?
What is rust
The horizontal rows on the periodic table are called what?
What are Periods
This is the first step in the Scientific method
What is "Ask a question"
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
This is the formula for how to calculate for the density of an object
What is D=M/V (Density = Mass / Volume)
This chemical property is is the ability of matter to burn
What is Flammability
The atomic number of an element tells us this about an atom of that element
What are the number of protons
This is usually written as an if... then.. statement
What is a hypothesis
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 Ort cloud
This physical property is the amount of space that an object takes up
What is volume
What is toxicity
All of the elements in group 1 on the periodic table have this many number of electrons
What is one electron
This is the variable that you change during an experiment
What is the Independent Variable
We get the term AU (Astronomical mass unit) from this general distance of measurement
What is the distance between the Sun and Earth
This is how you can find the volume of an irregular shaped object
What is water displacement
This chemical property is the ability of matter to combine chemically with other substances
What is Reactivity
When an atom has a different number of electrons we call it this
What are ions
This is the variable that changes during your experiment because of your independent variable
What is a dependent variable
