Inertia of an Egg Topic: To demonstrate the Inertia of an Egg. Materials Required: 1. Raw & boiled eggs 2. Glass plate Procedure: A dozen eggs are placed on a glass plate and one of them eggs is hard-boiled while the rest are raw. How can you find the hard-boiled egg without cracking the shell…
Sucking a balloon into a flask Level: Elementary/Secondary Concept: When water vapor in a frank is cooled and condensed into water drops, the pressure in the flask reduces greatly. Introduction: When water vapor changes into water drops,its volume reduces to less than one thousandth.Using this principle, we can make a virtual vacuum and let a…
in activity you learned about center of gravity. What is role of center of gravity with the nail balancer why don’t the overhanging nails tip the system over? Did you ever see a tightrope walker? They usually carry a low bending pole. Can you see a similarity with the nail balance? Do some research about…
How to make Arch model from Potato. The Arch is an ancient piece of technology and still common now days. Here is showing how you can make your own arch with potato or other hard vegetables. Material: A potato A sharp knife A ruler Hot To Make? Building of an arch is simple, you have…
Make your own Water prism. A prism is a transparent object that separates light into individual beams Difficulty Level: Elementary/Secondary Concept: Dispersion of light, Spectrum, Prism Introduction: We can see a clear spectrum projected on a wall using a plane mirror and water in a vessel instead of a prism. Materials: a water container (Tupperware),…
How to Make a Tornado in a Bottle Tornadoes are formed when warm, moist air swirls together with cool, dry air. They are most often associated with storm clouds that contain vortexes — spirals of rising air. As the vortex sucks in the surrounding air, more air moves in at a high speed to fill…
How To Make Hot Air Balloon To make Hot Air Balloon is an interesting and worth learning activity to learn about the relationship between properties of gases, temperature and pressure. Concept When we heat the gas, its volume increases and it inflates. Let’s make easy balloon by using this phenomenon. Materials required Garbage bag (thin,…
Fleming’s Left Hand Rule Experiment, Electric current and magnets. Level Elementary. Concept When two magnets are close together, magnetic forces are at work. Two magnets repel or attract each other. A wire carrying an electric current and a magnet also repel or attract, because electric current makes a magnetic field. Materials solder wire enameled wire…
How to make capacitor with aluminium foil and paper How to make capacitor with aluminium foil and paper cup : A capacitor is a device for storing a small electric charge. When two conductive plates are separated by a small insulator called a dielectric, they produce an electric field. Aluminum foil is conductive while cling wrap…
Make your own very simple Clip motor “DC Motor” Linear motor movement can be changed into rotation. For its construction you need following material. Materials paper clip(2), adhesive tape, magnet, enameled wire, sand paper or matte knife and battery. diagram Watch Video: Experiment2: Clip motor Materials: Enamel coated copper wire, Metal paper clip (2), 1.5…
Make a Handmade Spectroscope Measure a Light Wavelength! Concept: Light is a kind of wave How Do You Measure a Light Wavelength? Introduction: As you know, light is a kind of electromagnetic waves and its wavelength is 400 nm(Violet)～800nm(Red). T.Young measured the light wavelength for the first time using interference of light by double slits….
Concept: We can make a spectroscope using a CD instead of replica grating. Introduction: CD (Compact Disc) is used as a music media and a kind of computer memory media. When you look at the surface of CD under a fluorescent light or sunlight, you can see something like a rainbow. The reason is that…
