What is an independent variable?
How many hours are there in a day?
24 hours
Name the 3 states of matter.
Solid, Liquid and Gas
What is a pattern?
Something we observe to be similar over and over again.
What is a dependent variable?
The variable the scientist focuses his or her observations on to see the effect of the independent variable
Why can't we see stars during the daytime?
The sun is the only star we see during the daytime due to its brightness. Additionally, the sun is closer to Earth
These particles only vibrates in place and move very slowly because they are locked together.
Solid particles
Define orbit. How long does it take the earth to orbit the sun?
The path the earth follows around the sun. It takes the earth 1 year to orbit the sun.
What are constants?
If I see the moon now, how long will it take me to see the moon again?
24 hrs
Gas particles
Define gravity
The pull between earth and other objects, which acts without touching.

What is the IV, DV and Constant in the question below?
Esther did an experiment to test how the amount of salt affects the amount of time it takes for the water to boil. She used three different pots and put 500 mL of water into each pot. She put 20 g of salt into Pot 1, 40 g of salt into pot 2, and 60 g of salt into pot 3. She used the same type pot and the same type of salt. All of the water came from the same sink. Nina measured the amount of time it took for the water to boil in minutes.
IV= Amount of Salt
DV= Time to boil water
Constant= Type of pot, type of salt, type of water
What are yearly start patterns caused by? Why don't se see the same constellations each night?
Yearly star patterns are caused by the earth's orbit around the sun. The constellations we see throughout the year change because of where the earth is in its orbit around the sun.
Define volume
The amount of space a object takes up
What format do we use to write our Scientific explanations?
