The following Unit Studies are included in this E-Book:

Earthquakes Unit Study
Earthquakes are frightening events of nature that have terrible aftereffects for mankind. How do earthquakes happen? What have been the major earthquakes in history, and how can we protect ourselves from them? Join HLN in this cross-curriculum thematic unit on earthquakes.

Volcanoes Unit Study
Volcanoes are powerful forces of nature! Molten rock from inside the earth makes its way to the surface to relieve the pressure and shifts happening below the earth's surface. Learn more about the basics of where volcanoes come from in this unit for all ages!

Solar System Unit Study
When you look at the sky on a clear day, you see the Sun, shining light and giving off heat. When you look at the sky on a clear night, you see the Moon, stars and maybe some planets. Many of these objects are part of our solar system! Learn about our solar system in this unit with lessons that will take you out of this world!

The Sun Unit Study
The Sun is the closest star to Earth and is the main supply of energy for sustaining life on this planet. Research on our closest star allows scientists to learn more about how solar system began, about Earth's own atmosphere, and about other stars outside of our solar system.

Stars and Stargazing Unit Study
Summertime is the perfect time of year for stargazing, whether you do it the back yard, sitting on a mountaintop, or lying in a sleeping bag on a camping trip. The summer sky has many easy to recognize constellations and planets that even beginners can find without difficulty.

Moon and Tides Unit Study
Orbiting the Earth from an average distance of 384,403 miles, the moon plays an important role in how the Earth is shaped. Do you know the phases of the moon? Can you predict the tides? Learn more about how Earth's only satellite affects our planet today in this cross curricular journey to the moon!

Meteorology Unit Study
Each day, we turn on our televisions and radios, link onto the Internet and read our local newspapers to learn about the weather. The information we find out helps us decide what clothes to wear and what actions to take for the day. The science behind our daily weather reports is part of a science called meteorology! Explore meteorology in this HLN unit packed with fun-filled lessons and activities!

Hurricanes and Storms Unit Study
Hurricanes. Thunderstorms and lightning. Blizzards. They are types of dangerous storms that can wreak havoc over the areas that they strike. What causes those storms? How can you stay safe in extreme weather? Learn the answers to those questions and much more in this HLN unit about hazardous storms.

Understanding Wind Unit Study
Who has seen the wind? Neither I nor you: But when the leaves hang trembling, The wind is passing through. - Christina Rossetti. Here's a whirlwind of activities and lessons related to wind and wind power to explore!

Tornadoes Unit Study
Many people call tornadoes killer storms. Tornadoes can pack the strongest and fastest winds of any storm on Earth, whirling and twirling with powerful, frightening energy. Tornadoes strike with a violent force that can demolish homes, toss cars into the air, uproot trees and destroy whole towns -- in a matter of seconds!

Snow Unit Study
Snow is a fascinating and amazing form of precipitation. Did you know that it is commonly thought that no two snowflakes are identical? Have you ever wondered how much water is in snow? Are you puzzled by the fact that snow is white? If you have pondered these questions and are ready to quench your appetite with a snow-related menu, then this is the unit for you!

Aurora Borealis Unit Study
In this unit you will look at amazing images of the northern lights and find out the science behind their appearance. What causes it? When does it appear? You and your child can plan an imaginary (or real) trip to spot the aurora borealis and experience the magic and wonder captured by folktales of the past!

Archaeology Unit Study
Archaeology includes the study of the biologic and cultural evolution of man, the development of civilizations, and the study of time periods both through the study of written words and archaeological finds. Just like in other fields of study, archaeology has its own special fields. An archaeologist may be a specialist in ecology (how organisms interact with the earth), physical anthropology (human biology and anatomy), geology (study of the earth), and dimatology (the study of weather patterns).

Rocks and Minerals Unit Study
Rocks. We often think of them as nuisances or obstacles, yet they contain the essence for our survival-minerals. Rocks are composed of one or more minerals necessary to sustain life as we know it. Rocks also act as an impenetrable skin, shielding us from the molten hot magma that resides inside the earth. It is the weathering of these rocks that provides us with rich soils so that plants and animals can exist on Earth. Were it not for rocks, we simply would not exist.

Ozone Unit Study
Ozone can be found in two very different layers of our atmosphere, the troposphere and the stratosphere. Learn the terminology and skills used by today's scientists while focusing on one of Earth's most pressing environmental problems - ozone in our environment.

Earth Day Unit Study
Nothing is more crucial to the survival of any living organism than the health of the environment it lives in. Celebrate Earth Day by introducing your children to Earth's wonders, to the dangers that threaten them, and to the human actions that can protect them.

Chemistry Unit Study
Chemistry is defined by Webster's Dictionary as: The science of the composition, structure, properties, and reactions of matter, especially of atomic and molecular systems.A complex definition for a science that surrounds us every day! Join HLN today, as we become a catalyst to help your child understand chemistry…for all ages!

Tidal Zone Unit Study
What is the intertidal zone? What kind of animals and plants live in the regions we call tidepools? How have these organisms adapted to the environment they live in? Join HLN as we peer into tidepools and explore the life found in these rocky ocean zones!

Kites Unit Study
National Kite Month is celebrated in April with kite activities all around the country. Come learn more about the many surprising uses of kites in throughout histor and throughout and modern times!

Optical Illusions Unit Study
Did you know that going to the movies is a great way to experience an optical illusion first hand! When we go to the movies, our brains tell us that there is movement occurring on the screen in front of us. Come with us to explore illusions and their secrets!

Original electronic
Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
