In the hypothesis above, what is the independent variable?

Different Liquids

MRSTEC stands for 6 types of energy discussed this year. List all 6 energy types. 

Mechanical, radiant, sound, thermal, electrical, chemical

100

Barometer, anemometer, and hygrometer are all weather instruments. Which one measures humidity?

Hygrometer

Our solar system has two types of planets. What are these types and which planets are classified as them?

Terrestrial-Mercury, venus, earth, mars

Gas giants-Jupiter, saturn, uranus, neptune

A hair dryer is plugged into the wall. When it is turned on, what energy transformation occurs. Name the initial energy type and the final energy type. 

Electrical to thermal (some sound and mechanical too)

200

If I give plants different liquids, then they will grow at different rates. 

In the hypothesis above, what is the dependent variable?

Growth rate

200

What are resources that can be used over and over again? Give two examples also.

Renewable. Wind, hydropower, solar, geothermal, biomass

200

Our atmosphere is mostly composed of which gas? List any others you know. 

Nitrogen. Also oxygen and others

200

The term for Earth spinning on its axis, causing day and night. 

Rotation

200

What energy transformation happens with hydropower?

Water pushes a turbine (mechanical), that turbine movement transforms into electrical energy.
300
What variables would stay the same in an experiment where plants were given different liquids then measuring the growth rate?

Constants: plant type, container, soil, sunlight, amount of liquid given

300

What are resources that take millions of year to form and cannot be replaced easily?

Nonrenewable resources: oil, coal, natural gas, nuclear ("clean")

300
What is the relationship between altitude and air pressure?

Inverse. When one goes up, the other goes down.

300

The term for Earth orbiting the Sun. This also causes the seasons and lasts a year. 

Revolution

300

When a deer eats grass, what kind of energy transformation is occuring?

Mechanical to chemical

400

What does independent variable mean?

Independent I change. The one variable in the experiment that I change.

400

What is the term for the amount of energy the Earth absorbs and reflects?

Earth's energy budget

400

One air mass pushing another air mass of a different temperature out of the way is called what?

Weather front
400

List the planets in our solar system in order from distance of the sun.

Mercury, venus, earth, mars, jupiter, saturn, uranus, and neptune

400

The sun gives us what energy types?

Radiant and thermal

500

What does dependent variable mean?

Dependent data. Measurable data.

500

What are the three types of thermal energy and how are they shown?

Conduction- through touch. Radiation- through the air. Convection-through spiral currents of differing wind or water temperatures. 

500

List the 5 layers of the atmosphere in order from the surface up to space. 

Troposphere, stratosphere, mesosphere, thermosphere, and exosphere

500

The moon and the sun are responsible for what on Earth's surface?

Tides
500

Think of an energy transformation that starts with chemical energy and transforms into something else. Write down you example.

Answers vary. Chemical energy from food to mechanical energy to run. Chemical energy from batteries to sound energy for an alarm clock. Etc.
