200
This is how many days it takes for the Earth to revolve around the Sun.
What is 365 days?
200
This is the earth material that quickly absorbed the solar energy and released it just as fast.
What is dry soil?
200
This is to reflect.
What is to bounce back.
200
This is the effect of using a cover on a solar heater.
What is an increase in temperature?

What is Y-axis?
300
This is where your shadow is in relation to the light source.
What is the opposite side of the light source?
300
This is an example of a great heat sink.
What is water?
300
This is to absorb.
What is to take up, soak in, or capture.
300
This is the effect of using a light colored, uncovered solar collector?
What is a result of minimal temperature increase?
300
This is the direction of your shadow in the morning.
What is west?
400
This is the reason why the sandbox at a local park can have sun in the morning, but shade in the afternoon.
What is the result of an opaque object (building, trees, etc) being to the west of the sandbox.
400
This is the process of when solar energy passes through space and through Earth's air, hits earth materials, and warms up each material.
What is energy transfer?
400
This is one way to change our water heater design to make the water even hotter.
What is to increase the surface area or cover the container.
400
This is the axis of the independent variable. The information we knew before we started the experiment.
What is the X - axis?
400
These are the two experimental variables in our solar water heater investigation.
What is the color of the collector and covered vs. uncovered?
500
This is the reason that the sun appears to move across the sky from morning to noon to afternoon.
What is the earth rotating on it's axis.
500
This is a heat sink. (definition)
What is a material that gains a large amount of solar energy for it's volume and slowly releases it?
500
This is the best example of a solar water heater. (3 parts)
What is a large surface area, dark color (like black) and a clear covered container.
500
This is what happens to temperature when you increase the surface area of a solar collector.
What is the temperature increases?
500
This is the two part definition of surface area.
