This is another exciting way to teach kids the basics of pressure. It is also fun for adults too!

This science experiment is among my children's favorites. In this experiment we will attempt to blow up a balloon by mixing vinegar and baking soda. The chemical reaction will produce carbon...

The first thermometer was invented by Galileo and was based on the principle that air expands due to heat and contracts due to cold. Mercury thermometers are the most accurate and most common...

Hydrogen is a gas that has some interesting properties, it is HIGHLY flammable for one, also it can be made very easily, you just have to take the H out of H2O. Here's how...

Making an ecosystem in a bottle is a science experiment that allows you to study the delicate balance of nature and how an ecosystem thrives or fails. It shrinks the scope of nature down to a...

Children wonder where water comes from. We typically tell them that it comes from precipitation, and that it's stored in natural reservoirs such as ponds, lakes and streams. But any child who has...

This is a trick sometimes used by troops overseas in the desert when they have no means of keeping water cool, but you never know when it might come in handy!

Potassium iodide (KI) is a very difficult element to make since iodine is rarely found in nature. It is mostly used to treat thyroid conditions, prevent thyroid damage and protect the thyroid...

Agar plates are commonly used in scientific labs as a medium to grow bacteria and other microbes. If you are unable to procure prepared agar petri dishes, making them yourself is not a difficult task.

Due to its cooling nature, dry ice has many uses, from freezing perishable foods and carbonating drinks to induce precipitation through cloud seeding. Due to its reactive properties, dry ice can...

This is an easy, classic and fun way to introduce science to young children. It's an inexpensive experiment that can occupy kids time for hours while teaching them that science can be fun.

Hydrogen makes up 75 percent of the universe's elemental mass. It is used for many purposes, including preventing the oxidation of metals, and in liquid form, it makes rocket fuel. Hydrogen is...

Microscopes allow you to magnify items that you would not usually see with the naked eye. They are scientific aides and assist in the investigation of small items. You can make your own portable...

It's easy to make your own solar panel. While a home-made version doesn't have the power of a commercially manufactured one, it will generate enough electricity to be measured by a microammeter--a...

Parents and teachers can demonstrate to children that when certain chemicals are combined they can produce a reaction. One of these reactions causes the liquid to begin to glow in the dark....

Doctors use spirometers to measure lung capacity. The patient blows into the spirometer, and it measures how much air she can inhale and exhale. Building a spirometer is an interesting activity to...

Practically everyone understands the one major and most obvious characteristic of the lava lamp that makes it a lava lamp--water and oil don't mix together. However, there are some other physical...

Blowing up a balloon with baking soda and vinegar involves pouring the baking soda in the balloon, pouring the vinegar in a bottle and stretching the mouth of the balloon over the bottle, dumping...

Making a cloud in a bottle requires moistening the inside of a juice bottle with water, inserting a bit of smoke into the bottle using a freshly blown out match and pumping in air with a bicycle...

To make a tornado in a bottle, fill a plastic bottle partially with water, add a few drops of dish soap and add a bit of glitter before swirling the water around to create a miniature cyclone....

Dry ice is a cornerstone for many science projects dealing with carbon dioxide. When dry ice touches cold water, it causes it to boil and release the carbon dioxide, which will then pressurize a...

At amusement parks or family picnics on warm, summer nights, children of all ages enjoy wearing luminal glow stick necklaces and bracelets. These cool lights are created within plastic tubes and...
