The Characteristics of a Humid, Tropical Climate
Climates around the world are classified according to the Köppen Climate Classification System. The classifications in this system are based on temperature and precipitation averages on a monthly and yearly basis. One of the classifications is that of tropical wet climates, or rainforests. Humi
Exterior Sanding
Wood plays a vital role in indoor and outdoor structures, but being a product of nature, wood tends to weather and deteriorate when exposed to the elements. Sanding exterior wood smooths the grain, reduces the risk of splintering and removes grayed surface wood to reveal fresh-looking wood beneath.
Recipe for a Kids Volcano Science Experiment
One of the joys of being a kid involves exploring the surrounding world and figuring out how things work. Add in a good dose of creativity and imagination and the result is magic. Creating a volcano science experiment is a classic and fun science project that most kids enjoy. It can be the perfect p
How to Build Salt Crystals
Making salt crystals is an engaging way to teach students about the formation of crystals, evaporation and saturation. Salt crystals will form cubes or hexagon columns when water from a saturated solution evaporates. You can make salt crystals using household materials. Ensure that younger students
How to Do the Rain Drop Faux Painting
A faux rain drop painting is a decorative way to weatherize a piece of artwork without damaging the overall structure and detail of the piece. Paint drops on a piece of art create a sense of texture and realism that cannot otherwise be expressed in a plain painting. Adding paint drops to a painting
How to Check Recent Earthquake Occurrences Anywhere in the World
If you're interested in the dynamic nature of our planet, up-to-the-minute reports on earthquake occurrences around the world may also pique your curiosity. The U.S. Geological Survey offers this information to the public through its website. The site gives information not only on where temblors oc
Jumping Spiders Diet
There are several thousand species of jumping spiders (family Salticidae) found all over the world. Jumping spiders are the largest group of spiders on the planet and come in many different shapes and colors and exhibit diverse behavioral and ecological functions. Scientists have had difficulty clas
How To Match Wavelength With Color
Electromagnetic radiation in the visible spectrum, also known as visible light, ranges from 400 to 700 nanometers in wavelength. This range corresponds to all the colors from violet to red. Light with a longer wavelength has a lower frequency and therefore less energy. Light with a smaller wavelengt
How to Turn Green Wood Mugs
Turning with green wood is an economical alternative to buying seasoned billets. It's also a time-saver over gluing up your own project blocks. While green wood is something to be avoided by most woodworkers, for turners, it can be the answer to a prayer. It is cheap (free if you're willing to cut i
What Constellations are Close to Orion's Constellation?
The constellation Orion is also known as the Hunter after the story of Orion the hunter from Greek mythology. The Orion constellation includes the stars Betelgeuse, Rigel, and Bellatrix, as well three other stars that form a distinct line, known as Orion's belt. This line is often used to spot the c
How to Use a Wood Biscuit
Wood biscuits are oval-shaped wooden discs that are used in biscuit joinery. A tool called a biscuit or plate joiner is used to cut two crescent-shaped cuts into the ends of the two parts to be joined together. The wood biscuit is then glued and inserted into the crescent-shaped cuts as the joint is
How to Build a Double Pendulum
Double pendulums, also known as chaos machines, are physics wonders. These pendulums feature one pendulum arm with a second pendulum arm secured to the bottom of it. When spinning, the first arm moves in a rhythmic rotation while the second flails and flings itself about at random. These random move
Introduction to Linear Equations
Linear equations contain variables, or letter representations of unknown quantities, and numbers combined using algebraic operations. The general form of linear equations is ax + by = c where "a" and "b" are numerical coefficients, "x" and "y" are the variables and "c" is a constant. Linear equation
How to Calculate Milliamps
Ohm's Law is the basic formula for electronics. With it, we may calculate Resistance (Ohms), Voltage (Volts) or Current (Amps) by knowing any two of the three values.
How to Calculate the Distance Between Two Points in 3-D
Finding the distance between two points in three-dimensional (3-D) space is a common problem in mathematics (for example, in linear algebra) and in programming. A programmer would want to find the distance between two points for collision detection---for example, you might want to find out when a ba
How to Make a Hobby Rocket With a Parachute
Everyone knows the countdown that leads to a rocket launch: 3, 2, 1, lift-off. Building model rockets is a fun activity for kids and adults of all ages. Model rockets come in a variety of sizes and for different skill levels. Model rockets can be built from kits or built from scratch out of supplies
How to Color a Metal Chain
Metal chains come in a variety of sizes from quite tiny, such as jewelry chain, to quite large, such as the anchor chain on boats. Many types of chain change color over time due to rust, environmental exposure, or other reasons. There are several ways to change the color of metal chain including pai
How to Melt the Black Ice From My Driveway?
When temperatures turn to freezing and black ice forms a dangerous coating on the driveway, it’s imperative that the problem be taken care of quickly. Black ice is sometimes also referred to as “glare ice” or “clear ice.” Black ice is clear, not black, but is given its
How to Secure Heavy Items in a Shadow Box
Preserving memorabilia in a decorative manner has become a popular hobby. Many items are displayed on shelves or arranged in scrap books. Shadow boxes are an alternative for showing off mementos. Smaller items can be arranged in a shadow box using pins or tacks to attach them to the backboard. Secur
