Which type of rock is made from pieces of broken rock fragments?
Sedimentary Rock
Name the rock types in order in the rock cycle.

2. sedimentary
3. metamorphic
What is another name for a mini-model of a large design?
Prototype
How many things you you test or change during an experiment?
ONE
(keep everything else constant)
What do you call it when a river drops off pieces of rock and sediment in a new place?
Deposition
Which type of rock was formed by magma and lava?
Igneous Rock
What created the Grand Canyon?
The Colorado River (weathered & eroded it)
What is the first step in the engineering process?

Find a need
What do you call something in an experiment that you are either testing or controlling?
variable
What is it called when water, wind, or ice move broken fragments of rock?
Erosion
Which type of rock was changed due to a large amount of pressure and heat?

Give one input and one output of a laptop.
Inputs: electricity, keyboard, mouse
Outputs: heat, what appears on the screen or on your search engine
A scientists filled a test tube with lake water, took the temperature, and recorded it on her laptop and wrote it in her data journal. (field work)
Name all the pieces of technology she used
Test tube
Thermometer
Pen/pencil
Laptop
What created the Great Lakes?
Glaciers
Which rock type has crystals.
AND name an example of that type of rock.
Igneous:
basalt, obsidian, pumice, granite, gabbro
Some scientists do field work and lab work. If a scientist is studying the effects of rain on a lake, where would you find him in his field work?
Lab = in a science lab
Field = at a lake
What do you call a test that tests the strength of material?
Tensile test
What do you call the thing you're testing or changing in an experiment?
ex: if you're testing the effects of gatorade
Independent Variable
the athletic performance is the dependent variable since it depends on the gatorade
