How to make compass : The floating needle will behave like a compass, with one end always pointing to magnetic north. A story is told that this is the same type of compass used by Christopher Columbus. Since the metal needle of the time were poor, Columbus had a lodestone to remagnetize his floating needle….
How to make telephone with cup: A simple cup phone works by transmitting sound vibrations along a tightly-pulled thread. The telephone work in a very simple way. Sound waves cause the bottom of the first cup to vibrate. This vibration, in turn, cause the thread to vibrate. The vibrating thread causes the bottom of the…
How to Make Simple Music Instrument This activity will help children discover the relationship between the rate (speed) of vibration and the pitch (high-low) of sound. Material Needed 50 cm (20 in.) of mono filament fish line with a wooden dowel 10 cm (4 in.) long attached to one end Additional dowel Shoe box with…
See your voice : Sound is something most of us take for granted and rarely do we consider the physics involved. It can come from many sources – a voice, machinery, musical instruments, computers – but all are transmitted the same way; through vibration. This experiment changing sound wave into light so they may be…
How to make a lemon battery A lemon battery is made with lemon and two metallic such as copper and zinc. Copper and zinc work well together with lemon to make lemon battery because lemon contain citric acid similarly Tomatoes and other citrus fruits contain enough acid to effect the galvanometer. How to make a lemon…
Diy resistor from lead pencil Diy resistor from lead pencil ,This is a demonstration of variable resistance. The core of a lead pencil does n’t lead at all but it’s the graphite which conduct the whole process. Graphite will conduct electric current, but not as near as copper. Because it resists the flow of current,…
How to make an Electroscope How to making of an Electroscope : The electroscope is an easy-to-make device and should not be difficult to assemble for students who are motivated. They can use it to demonstrate the presence of an electrostatic charge in a comb, a balloon, or other charged object. As the charged object…
diy galvanometer | Design your own galvanometer Diy galvanometer, design your own galvanometer. In this activity you made galvanometer.In this activity you will learn simple construction of galvanometer. Try more winding in the coil, fewer winding in the coil, Try placing in the directional compass within the coil instead of a suspended needle on the…
Today I was studying about flux change and electromagnetism in which, I came to know that there is a simple project related to this. so I checked that was a to make a electromagnet. That was very easy and I made it in 5 minutes .it is really awesome you can check it at below…
Sometime when I need some wire so I took a full thread spool but I am done with my work it is difficult to rewind all that again. So today I though to make a winding machine. First I build a thread winding Machine. Then I programmed it to be controlled via Bluetooth. So I…
Introduction to Google Science Journal Google science journal The physical world around us is full of exciting natural phenomena that arises a number of questions in our mind about how things work and relate with each other. Among the various occurring in our surrounding we have some measurable quantities that help us to understand and…
How to Make a Vibrating Robot: Vibrating Robot the simplest walking robot. It is very simple in construction and functionality. It can be made by simple household things and due to its simplicity children enjoy it’s making and It is one of the popular Science Fair Projects. Materials required for how to make a Vibrating…
