Material required to make a simple periscope To make periscope, you will require simple household material such as: A 1 feet square card board piece Two mirrors of…
Homemade Perfume Besides enhancing the flavors of foods, chemistry can please our sense of smell, too. For thousands of years, people have collected the aromatic oils of plants and seeds in order to make sweet-smelling waters and perfumes. But they had to squeeze a great numbers of to get just a few drops of oil,…
Hot Air or Cold: Which Is Heavier? In this experiment you will learn about air motion, how Hot air rises and you will get answer why cold air is much heavier than warm air. Material: Wooden roller. Thread. Empty can Empty baby bottle Candle Method: Balance an “empty” baby bottle on one end of your yardstick…
How can mechanical energy produce electricity? When electric current flows through a coil of wire, a magnetic field is created around the wire. You will remember that from your experience in making electromagnets: that’s why electromagnets work. In this activity the opposite is happening. Instead of producing a magnetic field around a coil of wire…
Activity about Electromagnet. What is an electromagnet? How can you made? Materials needed 1m (1 yd.) of 22 gauge insulated copper wire stripped on both ends Lantern batter large iron nail no longer than 10 cm (4 in.) paper clips Procedure 1. In an activities 8.9 and 8.10, we learned that when an electric current…
Make simple linear motor: In this project you will learn how to make simple linear motor with thin aluminium pipe.It is very easy to make because you don’t require to many things to complete this project. Materials to make simple linear motor: Iron wire Copper wire (spare lead) Connecting wire with crocodile clips Bar magnet,…
When a drop of wax falls down on one side, the candle looses its balance and preponderates to the other side. There the flame grazes the candle, so that a drop of wax falls down also on this side. Candle looses its balance again and preponderates back again. So the candle swings until it runs…
How to Make a Hang-Glider For hang glider making you will need a sheet of A4 photocopy papersome paperclips. Method Fold the sheet in half across its narrowest part (its width). Paperclip both thicknesses together near the fold.Curl the halves of the paper outwards and downwards. Then clip together the corners A and B -…
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…
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 a hydrogen fuel cell : In this project you will learn construction of hydrogen fuel cell with simple house hold items, making of a hydrogen fuel cell at home without platinum coated wire is possible, this article contain video related to fuel cell, What is Hydrogen fuel cell? A fuel cell combines hydrogen…
Paper Chromatography Experiment for kids Paper chromatography is an analytical chemistry technique for separating and identifying mixtures that are or can be colored, especially pigments. This can also be used in secondary or primary colors in ink experiments. This method has been largely replaced by thin layer chromatography, however it is still a powerful teaching…
