observation
observation-uses 5 senses, inference-something we conclude based on our observations
T/F: the first step of the scientific method is to plan an experiment
false
T/F: tectonic plates are constantly moving
true
rocks formed when pieces of sediment compact and compress together
sedimentary rocks
footprints are example of this type of fossil
trace fossil
Give an example of a qualitative observation
her dress is red, his eyes are blue
variable that is measured in an experiment
dependent variable
scientist who said the continents were once a giant supercontinent
Alfred Wegener
rocks that are formed when lava or magma cools and hardens
igneous rocks
teeth are an example of this type of fossil
body fossil
gathering information using your 5 senses
observation
educated guess based on your observations
hypothesis
boundary in which 2 tectonic plates move towards each other
convergent
fossils are usually found in this type of rock
sedimentary rock
example of evidence for the continental drift theory
continents fit together, fossils and mountains found across oceans
give an example of a quantitative observation
variable that stays the same in an experiment
controlled variable
boundary in which 2 tectonic plates move away from each other
divergent
rocks formed from heat and pressure
metamorphic rocks
Pangaea
give an example of an inference
answers will vary
variable that is changed or manipulated in an experiment
independent variable
boundary in which 2 tectonic plates slide horizontally past each other
transform
T/F: weathering and erosion break down rocks into smaller pieces called sediments
true
false
