How to Make a Bow and Arrow that would make Robin Hood Proud

Making a bow and arrow in the movies seems easy enough, and it is indeed fairly easy once you get the hang of it. Characters in books, movies, and even online games have archers in it and they are very popular, like Legolas in the Lord of the Rings, the winged Cupid, and Robin Hood of course. So how
How to Calculate the Density of a Molecule

How to Calculate the Density of a Molecule

The study of chemistry requires knowledge of molecules and their properties. In order to understand how elements will react under different circumstances, it can be useful to calculate basic properties of these materials, such as density. The density of a molecule, or mass divided by volume, is an i
How to Convert Integers to a Base-4 System

How to Convert Integers to a Base-4 System

Standard numbers comprise a base-10 system, meaning you count up until you reach 10, at which point the digit is reduced to zero and one is added to the digit to the left. Other base systems work on the same principal, so in a base-4 system, the number 11 is the same as the number five in a base-10
How to Build a Dome Out of Foam

How to Build a Dome Out of Foam

A foam dome can be constructed easily by beginning with a foam ball. Since they vary in size from 1/2-inch diameters to 48-inch diameters, you can select the size that most closely meets your project needs. The surface texture of foam balls varies as well. You can choose a rough surface, such as the
How to Build a Model Railroad Turntable

How to Build a Model Railroad Turntable

A model train, just like a real one, can only travel in two directions: forward or backwards. To be able to switch a model train's engine from one track to another that is not parallel to it, build a basic railroad turntable to rotate the engine. Supplies from a hobby shop or home and garden store w
What Are the Five Biotic Factors of an Aquatic Ecosystem?

What Are the Five Biotic Factors of an Aquatic Ecosystem?

Organisms in an aquatic ecosystem are affected by both biotic and abiotic factors. Biotic factors include other living organisms, such as fish, plants and bacteria. Abiotic factors refer to non-living phenomena like temperature and the amount of sunlight. The five biotic factors in an aquatic ecosys
Abiotic Factors of the Neritic Zone

Abiotic Factors of the Neritic Zone

The neritic zone is the portion of the world's oceans stretching from the edge of the intertidal zone to approximately the edge of the continental shelf. It forms part of the epipelagic zone, the 200 meters closest to the surface, which is also known as the sunlight zone. Accordingly, this is the pr
Altitude for Scorpions in Colorado

Altitude for Scorpions in Colorado

Scorpions are extremely adaptable, as these arthropods can live virtually anywhere there is soil. Commonly found throughout the world's desert regions, scorpions can also live in high, mountainous environments. Of the nearly 2,000 species, three are native to Colorado: the northern scorpion, the nor
How to Make a Solar System Model

How to Make a Solar System Model

The Earth and the other planets revolve around the Sun to make up the Solar System. The nebular theory states that the solar system began as a huge cloud of dust and gas, which then condensed to form the Sun and the planets. Solar System models for physics classes can be made by students in the cla
Information About Quartzite

Information About Quartzite

Quartzite is a metamorphic rock created from changes to the sedimentary rock, quartz sandstone. Unlike quartz sandstone, however, quartzite fractures across its granules, rather than around them, making neat flat breaks. This makes the erosion-resistant quartzite useful for both decorative items and
How to Make a Wind Direction Gauge

How to Make a Wind Direction Gauge

Wind direction gauges--also called "wind vanes" or "weather vanes"--date back as far as 48 B.C.E., with the earliest recorded gauge built by astronomer Andronicus to honor the Greek god Triton. Since then, weather vanes have evolved into an effective means of measuring the direction of oncoming wind
How to Make an Accurate Rain Gauge

How to Make an Accurate Rain Gauge

The amount of rain received during a given time is difficult to judge by simply watching it fall. That is why rain gauges are used to accurately measure the amount of actual precipitation. Rain gauges are tube-like devices that catch the rain as it falls to the ground. A scale on the side of the gau
How to Build a Modern House on "Sims 2"

How to Build a Modern House on "Sims 2"

Modern homes, sometimes called contemporary homes, in "The Sims 2" have a unique style that is very geometric and clean. Roofs tend to be flat and often double as rooftop gardens. They have a lot of single-pane windows that add to the look of the house while providing optimal lighting inside. Doors

It also depends on the number of people doing the job. The more people to help you, the faster the sanding gets done. It will be worth every d
Alternatives to Neon Transformers

Alternatives to Neon Transformers

Neon transformers are commonly used in the making of Tesla coils. A Tesla coil is a resonant transformer circuit. It produces high voltage, low current, and high frequency alternating current electricity. These coils are employed in x-ray technology, electrotherapy, and to transmit electrical energy
