Experiments Archives. Sprouting Seed ActivityHousing a Forest. Spring is right around the corner, and I am SO excited! There is something about new life sprouting up that makes me really happy. While visiting my parents, they engaged the kids in a simple sprouting seed activity. My mom loves to garden, so this was the perfect project to take on while visiting her. I love her seed stash. She enjoys saving seeds and has a number of different varieties of seeds she has collected over the years. We created simple mini greenhouses with recycled tins, damp paper towels and a plastic bag. Lay a damp paper towel on the bottom of your container and gently “plant” your seeds. Once everything was planted in our greenhouses, we each made predictions on which seed would be the first to sprout. We were amazed that by the next evening the cucumbers, broccoli and scarlet runner beans had already started sprouting. A few days later, the trays were exploded with sprouted seeds and plants.
Here is a link to a fun list of great experiments that my kids love. FIRST LEGO League | FLL is the result of an exciting alliance between FIRST® and the LEGO Group.

Clocks are made to give precision to our day. They allow us to budget our time, and also to coordinate our activities with others whom we would meet at certain times. If not for clocks how would we know when to go to work or school? How would we know when the play at the theater begins? And most importantly, how would we know when to get home for supper? Even people's lives depend on clocks, if air traffic controllers could not denote time, there would be many more airplane accidents. Military operations are very dependent on time coordination. Even spies, who must "synchronize their watches", understand that knowing the time is an important matter.
What clocks actually do is measure time. All clocks have a couple of requirements. There are many kinds of clocks and it is the objective of this website to explain how some of them work. The hour glass was the next innovation. Pendulums were a great leap in technology. Atomic clocks have increased the accuracy of time keeping even further. Microscope: History, How Microscopes Work, Light and Electron. Microscopes are one of the vital tools that have allowed science to leap forward in many fields, biology, medicine, and anatomy, just to name a few. The microscope gives humans the ability to study the very small. This view of a realm that is beyond our vision with the naked eye enables understanding of how new drugs work, the way genes are constructed, even how atoms bind together to form larger molecules. It has been said that the scientist of today stands on the shoulders of giants. This is meant to signify that we have before us the body of thought and the work of the greats of the past who compiled the information and formulated the ideas we use to advance scientific fields.
To reconstruct the work of a man such as Robert Hooke would take the average person a life-time. The microscope as we know it was developed by a father and son team, spectacle makers named Zaccaria and Hans Janssen, who thought of lining up two lenses in a tube.

Telescopes help us to see far distances. The first telescope was invented in the early 1600s in the dawn of the Scientific Revolution. Before then people had to rely on the naked eye. Much reliance was placed on people with sharp eyes. When telescopes came about they were quickly adopted by mariners and travelers and members of the military. We will show you how telescopes work and will give you some idea about how to find a telescope for your own purposes. Refracting Telescopes use lenses in order to form an image and magnify it. Reflecting Telescopes use mirrors to form an image.
Radio Telescopes are used primarilly for scientific and military applications. How to Choose a Telescope? Next Page: Refracting Telescopes. Global Positioning System - How It Works! - InDepthInfo. The Global Positioning System (GPS) is used for all kinds of purposes in modern life. It was originally created in order to help navigators find their way around on the wide ocean where there are no landmarks. It slowly supplanted traditional means of fixing a position on the ocean. (At one time mariners used the altitude of stars for this purpose.) But the ability of the system to find locations with almost pinpoint accuracy has made it useful for navigation on land as well.
Navigation systems are now regularly installed in automobiles and hand-held devices are a common site on hiking trails and even on city streets. At this site we try to explain in general terms how the GPS works. Each satellite has specific characteristics. The Satellites are placed at regular intervals around the planet in order to facilitate pinpoint navigation. There are many applications for the GPS. Next Page. How Gadgets Work! In order for society to advance technologically, people must have at least a general understanding of how gadgets work.
The technology behind the gadgets that make our lives easier and more fun is not as complex as many would think. Much of it is based on simple ideas put to a practical use. Below is a list of gadgets we have investigated in detail: Vacuum Cleaners are an item that has saved time and money and made living cleaner and healthier lives more commonplace. Refrigerators cool food, but how? Street Sweeping Machines have been around for over a hundred years, keeping streets and roadways clean. Camcorders record motion without film. Smoke Detectors do more than make loud, screeching noises. Metal Detectors may help you find ancient burried treasure, but they are based on a technology that is much more recent. Light Bulbs are deceptively simple. Microphones help us to be heard even when we speak softly. Projectors still use old ideas in the new technology.
