General
What do you need for a scientific explanation?
Claim, Evidence, and Reasoning
What is rotation
Earth spinning on its axis
What are constellations?
A group of stars forming a pattern.
What is a pattern?
Something that repeats over and over again.
Name the three states of matter
solid, liquid, gas
The things you keep the same in an experiment.
What is earth's orbit?
The circular path earth makes around the sun.
How many stars are in our solar system and what are they?
One - The sun.
Why do we see our daily patterns?
Earth's rotation
What doe the particles of solid matter look like?
The particles are tightly packed and locked in place.
What is the difference between affect and effect?
Affect (verb): to cause/change something
Effect (noun): the outcome
Why do objects on earth not float off into space?
Gravity; the force that pulls objects toward the center of the earth/ground.
At different parts of the year, we see different _____. This is because of earth's ________ around the ______
constellations, orbit or revolution, sun
Given today's date (Year 2025), how many revolutions has the earth completed?
2023
Close together but can still slide past each other.
Independent variable is the one thing you change in an experiment. The dependent variable is the thing you measure/observe.
How many times does earth complete a rotation on its axis in 24 hours?
Once
What time is the sun directly above you in the sky?
Noon or 12pm
How many complete rotations does earth complete in a year?
365
The particles are far apart and moving really fast.
A teacher wants to test if the amount of sleep students got affected their Science IA scores. Identify the independent and dependent variable and constant.
DV: IA scores
C: Science IA exam
What would happen if the earth rotated but never revolved around the sun?
We'd still see day and night, but we won't be able to see different stars throughout the year.
Give 2 pieces of evidence to support the claim that the sun appears larger and brighter than other stars because it's closer to earth. Make sure to explain the evidence.
a) in the simulation I saw that the sun was the closest star to earth while other stars were farther away. b)In a text I read that the sun is only 8 light minutes away from earth while other stars were lightyears away c) I learned from a classwork packet that objects that are closer appear larger and brighter like car headlights d) In class we did a model of the earth and sun and saw the earth was closer to the sun than other stars.
What pattern does the sun rise and set? Explain why that happens.
Sun rises in the east and sets in the west. We see this because of earth's rotation.
Name 3 properties you can observe about a substance.
Taste, Scent, Texture, Sight, Sound.
