Let’s make the fog in the bottle. At the moment when the rocket was driven, it becomes white in the PET bottle momentarily. It is because the temperature rapidly falls by the adiabatic expansion when an inside gas expands suddenly. The fog can be made in the PET bottle in the classroom by using this…
How to make ammonia fountain How to make ammonia fountain : The ammonia fountain is a great demonstration used to notice the solubility of ammonia in water. Materials needed how to make ammonia fountain Ammonia solution, test tube clamp, phenolphthalein, PET bottle or glass bottle with cap, injection syringes, straws, beakers, test tubes, spirit lamps,…
How to make Magic Water-Proof Sand (Magic Sand) In this science experiment you will learn how to make water proof sand (magic sand). Normally when water is added to sand the outcome is predictable. The water soaks in and the sand becomes wet and sinks. This is not the case with water proof sand! Water…
Make a simple periscope A periscope is a device commonly used in the submarines to observe above the sea water while keeping the submarine under the water. 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…
Make a solar cell in your kitchen Make a solar cell Video 1 Make a solar cell Video 2 A solar cell is a device for converting energy from the sun into electricity. The high-efficiency solar cells you can buy at Radio Shack and other stores are made from highly processed silicon, and require huge…

Electromagnetism Experiment 1 Which direction does the aluminum foil move to? Materials: Aluminum foil, Dry cell, Bar magnet, Scotch tape Procedure: Paste the Aluminum foil of 1mm wide on the table with tape as shown in Fig.1. The shape of Aluminum foil is half-circular.Pass electric current through the Aluminum with a dry cell and bring…
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 the energy of sound cause something to move? This activity shows that sound can actually do work. It can make something move. Energy is transferred from one guitar to other by sound waves. And the strings of the second guitar vibrate. The two guitars should be tuned alike so the vibrating frequency is…
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…
