Monday Homework: Answer the following questions./Study for Test
1. Name the steps of the scientific method in order.
1. State the problem
2. Make observations
3. Form a hypothesis
4. Experiment or Test the hypothesis
5. Record and analyze data
6. Draw a conclusion
7. Communicate your results

Suzie Q wants to know how different colors of light effect the growth of plants. She
believes that plants can survive the best in white light. She buys 5 ferns of the same
species, which are all approximately the same age and height. She places one in
white light, one in blue light, one in green light, one in red light and one in the
closet. All of the ferns are planted in Miracle-Grow and given 20 mL of water once a
day for 2 weeks. After the two weeks, Suzie observes the plants and measurements.
3. What is the independent variable? Different colors of light
4. What is the dependent variable? Growth of plant
5. What is the control variable or constant? Same species of ferns, same age and
height, 20 mL of water, and Miracle-Grow
Control Group: White Light
6. What are the SI unit for the following: Length, Mass, Volume, Time, and Temperature
a. length- meters (m)
b. mass- grams (g)
c. volume- milliliters (mL) or Liters (L)
d. time-seconds (s)
e. temperature- Kelvin (K)
7. What is the thickest layer? What is the thinnest layer?
Thickest layer: Mantle Thinnest layer : Crust
8. Name the layers that are completely solids( 3) and name the layers that are not completely solids (3).
Completely Solids
Not completely solids
Crust
Mantle (soft solid)
Lithosphere
Asthenosphere (soft solid)
Inner Core
Outer Core (liquid)
9. Which wave cannot travel through the outer core? Explain why?
The Secondary or S-wave cannot travel through the outer core because it cannot travel liquids.
It only travels through solids therefore it STOPS at the outer core, which is a liquid.
10. Create a chart depicting the difference among the 3 types of seismic waves. (include the wave’s motion, speed,
position, and what states of matter it can travel through.
Position

Tuesday Homework: Answer the following question./Study for Test
1. What is the difference between the focus and the epicenter of an earthquake?
Focus is where the earthquake starts and it releases the energy (seismic waves).
Epicenter is located right above the focus and releases the greatest amount of energy.
2. Illustrate and explain the triangulation process.
Triangulations is a process that locates the epicenter using 3 circles.
epicenter
Epicenter
3. Could the epicenter be on or in a circle? Explain your answer.
The epicenter Is ON the circles because it is located where the 3 circles meet.
4. What process can all rocks go through? When rocks go through that process, what do they turn into?
All rocks can go through weathering and erosion and when it goes through that process,
The rocks are broken down into sediments.
5. Create a chart depicting the difference among the 3 types of rocks. (include the rock’s processes and where
they form)
Rock A
Rock B
Rock C
Process
Heat & Pressure
Type of Rock
Metamorphic Rock
Forms Form
Underneath Earth
Surface
Cooling,
Crystalizations &
Melting
Igneous
Volcanoes
Compaction &
Cementation
Intrusive-inside,
magma, large
crystals, cools slowly
Extrusive-outside,
lava, small or no
crystals, cools quickly
Sedimentary
Near bodies of water
(fossils & Layers)
Rock D
Weathering & Erosion
Any type of rock
6. Why do humans use fossil fuels? To burn energy
7. What is the difference between renewable and nonrenewable resources? Give examples as well.
RENEWABLE RESOURCE
NONREWABLE RESOURCE
DEFINITION
RESOURCES that can be renewed or
Resources that can not be renewed or
replaced
replaced
EXAMPLE
Water, Wind, and Sun
Fossil Fuels (Natural Gas, Oil, and
Coal)/ Diamonds
8. Explain what occurs during a subduction zone? (Include what crust sinks and why)
Subduction zone includes both the oceanic and continental crust. The oceanic crust sinks because
It is more dense and continental crust is less dense.
9. Which crust is oldest and which crust is the youngest? Explain why?
The oldest crust is continental and the oceanic crust is the youngest because it is being recycled
In the mantle by the convection currents.
10. What is the difference between a mountain and a volcano?
A volcano is a mountain with a vent or hole on top of it.
11. Illustrate a hill or mountain on how it would look on a topographic map and identify the following: peak,
contour lines, and contour intervals.
