drawings from a 5-year old:

This exciting new giant-screen filmbrings audiences into amazingly small places and introduces them to incredibly big ideas.

The Molecularium® Project has produced an entertaining, animated science film for young people, families, and school groups. It’s a magical, musical adventure into the nanoscale world of atoms and molecules.

Catch a ride with Oxy and her atom friends aboard Molecularium® – the most fantastic ship in the Universe – as they explore the secret worlds within everyday objects.Blast through the far reaches of space, discover the elements of the Earth’s atmosphere, fly through the molecular structure of a snowflake, escape the polymer tangle of chewing gum, get lost in the metallic maze of a penny, and explore the inner workings of a human cell.

To the delight of school teachers and parents alike, it has been clearly demonstrated that kids of all ages genuinely learn and retain an amazing amount of the educational content and thoroughly enjoy this entertaining experience.

So just how small is small ?• There are 1 million nanometers (nm) in 1 millimeter (mm).• An average sheet of paper is over 1.5 million atoms thick.• A penny has over 2 x 1022 atoms of copper and zinc. • A stack of 2 x 1022 pennies would be over 1 trillion kilometers high.

EVERY THING IS MADE OF ATOMS !Anything that takes up space and can be weighed is made of atoms.Atoms are the incredibly small, basic building units of matter. Every thing in the Universe - this page, every book, person, planet and star, even the air - is made of trillions and trillions of atoms!

Even atoms have parts, called subatomic particles: protons, neutrons, and electrons.At an atom’s center is the nucleus, a dense core that contains 99.9 % of it’s mass.

The nucleus is made of positively charged protons and neutrons with no charge.

Much smaller negatively charged particles, electrons, are attracted to the positively charged nucleic mass and orbit it in a “cloud” at nearly the speed of light.

This illustration is NOT to scale. Atoms are 99.9% empty space.Protons and neutrons are about 2000 times larger than electrons and the distance between them is vast.

If an atom’s nucleus were the size shown here, the closest electrons would be over 100 meters away.

Try This:Cut a sheet of paper in half. Cut it in half again.Do this 29 more times and it will be as small as an atom !

The Hydrologic CycleH2O on Earth is continually circulating between the oceans,

the atmosphere, and the land as part of the Hydrologic Cycle, also called the Water Cycle. The total amount of H2O in this continuous cycle doesn’t change, it only changes its physical state and location.

Liquid Atoms and molecules in the liquid state are not locked in place and move around. Liquids have a definite volume but change shape based on their container.

Condensation When air begins to cool, it loses the ability to hold as much water vapor, which condenses back into aliquid, forming very small droplets that make up clouds.

GasIn a gas, atoms and molecules are spread out and moving very fast,randomly colliding with each other and with walls of any container. The volume and shape they occupy can easily change. A gas has a very low density compared to a solid.

SolidAtoms and molecules in a solid are tightly packed, often in a regular pattern.While the atoms vibrate, they don’t change their average position in relation to other atoms. Solids have a definite shape and volume. Solids usually have the highest density.

STATES OF MATTERMatter has different physical states at different temperatures. Generally, as temperature rises, atoms move faster. There are three main states of matter: solid, liquid, and gas.

Precipitation As the air gets more moist, the droplets of condensed water vapor in clouds grow larger and larger until they become so heavy they fall back to earth as rain, snow, sleet or hail, depending on the conditions, mainly temperature and pressure.

Evaporation The sun’s energy heats liquid water on the surface

of oceans, lakes, rivers, and even puddles, changing it into water vapor, a gas. Most of the water that evaporates

into the atmosphere comes from the oceans (86%), changing it from salt water to fresh water and keeping the oceans from over-heating.

Some Common Molecules

WATER...is the only natural substance that is found in all three states – solid (ice), liquid (water) and gas (vapor) - at the temperatures normally found on Earth.

Where’s the water ?70% of Earth’s surface is covered by water.97 % of Earth’s surface water is in the oceans.2.4 % is in ice caps and glaciers.0.6 % is in lakes, ponds, rivers, and streams.

When atoms in a solid arrange themselves in orderly repeating patterns, they form crystals, like ice and diamond.

PREDICT and OBSERVE: Take a picture of a dry glass. Fill it with ice water.

Predict what will happen to the outside surface of the glass.

In 10 minutes, take another picture of the surface of the glass.

Compare the photos.

MOLECULESAtoms bond with other atoms to form more complex structures called molecules. An example is 02. Bonds between atoms are formed when they share, or give other atoms, their outermost electrons (valence electrons).

Molecules made of different kinds of atoms are called compounds. Though there are a limited number of chemical elements, there are an unlimited number of molecules that can bemade from them. Chemical formulas are used to easily identify the atoms that make up molecules and to representhow the relationships between those atoms change during chemical reactions.

Grow your own Crystals: You will need:

4 oz of alum (in the spice section of your grocery store) Heat 2 cups of water until almost boiling. Dissolve the alum in the water.

Pour into a small clear cup and cool. After an hour... check for crystals!

Explain what happened and why.

POLYMERS: Plastics, Paper, Cotton, and ProteinsPolymers are large molecules (macromolecules) made of small molecules, monomers (or just mers), repeatedly joined together end-to-end into very long chains. Poly- means “many” and -mers means “parts”.

Plastics are polymers. Plastic bags are made from polyethylene, the simplest polymer structure.A chain of carbon atoms forms a “spine” with hydrogen atoms along the sides.Over 60 million tons of polyethylene is produced worldwide every year. Although it can be recycled, most of it ends up in landfills and the ocean, which is of great environmental concern since it takes many centuries for most plastics to breakdown.

Cotton fiber is nearly pure cellulose, a natural polymer.It’s the structural component of green plants’ cell walls

and the most common organic compound on earth (33% of all plant matter). Paper made from

trees and plants is also mostly cellulose.

Proteins are natural polymers made of amino acids linked end-to-end. They are essential for plants and animals to grow. Most plants andmicroorganisms can make the 20 “standard” amino acids, but animals must get some essential amino acids from the proteins in the food they eat.

Did you know ? Chewing gums contain polymers that make them chewy.

The polymers used in gums are often the same polymers that are used in tires and sneakers.

Here’s how you can find out how much polymer is in a piece of gum: 1) Weigh a piece of gum. 2) Chew until it loses its flavor. 3) Weigh it again.

This is the amount of polymer in the gum. The difference in weight is the amount of sugar and flavoring. You can calculate the percent of polymer by dividing the weight

after chewing by the weight before and multiplying by 100.

DNA is a macromolecule found in the nucleus of living cells that carries genetic information that is copied and passed on from cell to cell and generation to generation. This information, necessary for a living organism to grow and function, is contained in segments of DNA called genes. DNA is made of two long polymer chains that twist together to form a double helix. Each of these polymer chains is made of simpler units called nucle-otides, which contains one of four different bases: adenine (A), thymine (T), guanine (G), and cytosine (C). These bases pair up and form bonds between the two strands of the helix. Adenine only bonds with thymine, and cytosine only bonds with guanine. These base pairs are often pictured as rungs in a twisted helical ladder.The sequences of these base pairs in DNA strands are the keys to the genetic code of all life. Long sequences contain coded instructions which are used by cells to make different proteins that are involved in the many different functions necessary for life.

DNA: The Atomic Code of All Life(Deoxyribonucleic Acid)

TEST YOURSELF:1. How many chromosomes does a human cell have?

2. What is the Y chromosome?3. How many different types of atoms do you think are in DNA?

Answers: 1) Each human cell has 23 pairs of chromosomes for a total of 46. Half of each pair comes from each parent. 2) The male chromosomes. 3) Only 5 - hydrogen, carbon, nitrogen, oxygen and phosphorus

DNA Facts: • Chromosomes are tightly twisted coils of DNA wrapped around protein structures. • Each chromosome contains just a single strand of DNA. • The average human cell contains over 2 meters of DNA. • If you took all the DNA in the human body and stretched it out, it would would reach to the Sun and back over 50 times !

Hydrogen is the simplest, lightest and most abundant element in the universe. It is estimated that 90% of the universe by weight is composed of hydrogen. Most stars are composed mainly of hydrogen.

Nitrogen makes up 78% of Earth’s atmosphere .

Oxygen makes up 21% of Earth’s atmosphere and about 65% of the mass of the human body.

It is the third most abundant element in the universe.

Argon is inert and does not bond with other elements.It makes up almost 1% of Earth’s atmosphere.

Can you find our characters in the Periodic Table ?
