Nature of Science
This EXPLAINS WHY something happens in the world. They improve when we have better evidence.
What is a theory?
Water/wind/ice/gravity break landforms or rocks down into smaller pieces.
weathering
Helpful traits allow some individuals to __________ long enough to reproduce.
What is survive?
The force of attraction that pulls us towards the Earth (and Earth towards the sun, etc).
What is gravity?
This DESCRIBES WHAT happens in the world. It often has a formula, like Ohm's says V = IR.
What is a science law?
We use these in science to visualize and study scientific concepts that we can't easily observe in real life (like the movement of tectonic plates).
What is a model?
One type of evidence for past life that can be found in rocks is _________ (can be bodies or footprints, etc).
What are fossils?
The universe contains _(five/hundreds/ billions)___ galaxies.
What is billions (or maybe even 2 trillion)?
This is the variable I test. I can only change 1 in a fair test.
What is the independent/test variable?
This process formed Florida's beaches. It's when sediment & rocks are placed in a new location.
What is deposition?
The Law of Superposition says that newer fossils are found closer to the ________.
What is surface of the Earth?
We measure distances across our galaxy in ________ ___________.
What is light years?
The data I collect during my experiment (it's the outcome I'm measuring).
Plate Tectonic _______ explains that moving crustal plates cause volcanoes, earthquakes and mountain-building.
What is theory?
If there's change in the environment, a species that doesn't have adaptations for the change may go _____________________.
What is extinct?
There are often __(tens, hundreds, billions)__ of stars in a galaxy.
What is billions?
When we do multiple trials & find the best value, that's an example of ________. A complete re-do of the experiment is called ________.
What is repetition & replication?
Here are some examples:
-sediment is compressed into rock
-lava cools into igneous rock
-heat & pressure compress sedimentary rock into metamorphic
What is the rock cycle?
Cell Theory: All living things are made of ________. Cells are the basic unit of life and come from ___________ ____________.
This is the reason that sound does not travel through space.
What is 'sound moves through molecules, and space is mostly a vacuum'?
