Which parts of the water cycle carries air pollution from the atmosphere to the lithosphere?
Precipitation carries air pollution from the atmosphere to the lithosphere.
100
According to most scientists, the source of energy that sustains life comes from where?
Most scientists believe the source of energy that sustains life comes from the sun.
100
What is the variable that the experimenter changes so that he/she can measure the results?
The independent variable
100
What is an example of stored energy?
A dog sleeping is an example of stored energy.
100
What is technology?
Technology is anything that extends human capabilities.
200
Solar energy directly powers which transformation of the water cycle?
Evaporation from oceans and transpiration from plants is directly powered from solar energy.
200
Why is it important to protect Earth's water resources from pollution?
It is important to protect Earth's water resources from pollution since polluting the Earth's water resources makes water unavailable or unsuitable for sustaining life.
200
What variable is measured?
The dependent variable is measured.
200
How many paths does a parallel circuit have?
A parallel circuit has more than one path.
200
What are constraints & list them.
Constraints are limiting factors; cost limits, times limits, supply of materials, and environmental effects.
300
In which parts of the water cycle does gravity transport water?
Precipitation and run-off is transported by gravity in the water cycle.
300
What would not a typical problem experienced when an ecosystem is over populated?
Many resources would be available (such as food, shelter and water).
300
Which variable is kept the same throughout the experiment?
The constant variable is kept the same.
300
What energy transformation takes place in a Newton's cradle?
The energy transformation that takes place in a Newton's Cradle is Potential>>kinetic>>>>potential.
300
Name an undesirable & desirable effect of technology.
Undesirable effects of technology: pollution, warfare, automation. Desirable effects of technology: entertainment, faster production, automation.
400
In which parts of the water cycle does water change from liquid to gas?
Transpiration and evaporation changes liquid to a gas.
400
Name two abiotic factors and two biotic factors living and interacting in the ocean.
Plants living in the sand & fish breathing oxygen.
400
I kept the amount of sunlight, temperature, fertilizer and water the same for my three green plants. What might I be testing?
What type of soil do plants grow best in?
400
(DOUBLE JEOPARDY) What kind of weather does a cold front bring?
A cold front brings rain & cooler temperatures.
400
Name a problem that CANNOT be solved by scientific research.
A moral problem.
500
List the four steps of the water cycle and describe what takes place at each step.
Run-off- water that run offs the land into a body of water Evaporation-water that evaporates into a gas Condensation-water collected in clouds Precipitation-rain that falls to the Earth as rain, sleet, hail, or snow

In 1989, the oil tanker Exxon Valdez spilled oil off the coast of Alaska. The oil covered aquatic plant life and small birds and animals. Describe the effects an oil spill, such as the Exxon Valdez oil spill, has on the transfer of energy in an ecosystem.
One, the oil may kill the plant life making it impossible for plants to perform photosynthesis. Second, the animals that eat plants will have less to eat and will have to move. Lastly, the other animals that eat the small animals will have less to eat too and will need to find something else to eat or move on.

Mrs. Hansgen played different types of music in during testing for her students. The different types of music is the independent variable. What is the dependent variable?
The scores on the tests would be the dependent variable.
500
What is the energy transformation found in an battery-operated hand-held fan?
Chemical>>electrical>>>heat (battery)...>>>>mechanical (fan blades turning)>>>heat
500
Why is automation considered an undesirable AND desirable effect of technology?
Automation caused people to lose jobs and also it created jobs.
