Make a Mini-rocket launch This is a fun experiment demonstrating what happens when acids and bases react. Remember: What goes up must come down – So wear safety specs unless you want a rocket through your eye socket! Ingredients Rocket fuel- an Alka Seltzer tablet (or if you can’t get any, some bicarbonate of soda…
How seed fly: Flying seed, Alsomitra model Flying seed Level Primary Concept The plant spreads seeds to leave offspring by a variety of methods. A certain kind of plant seed flies over air. Let’s make flying seed models look like two plants, Alsomitora, and Lauan. Materials cardboard, clay, scissors, stapler, paper clip, bamboo skewer and…
You will need two small, light pulleys scrap wood dowel string paper pin or nail Use construction paper or poster paper for the pinwheel. Assemble as shown. Demonstrate by blowing fan at pinwheel, showing that this windmill performs work by turning the pulleys. Explain that wind power may soon be an important energy source
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…
Hypothesis If the amount of water is increased the pitch gets lower. I can make music with the bottles of water. Materials needed eight glass soda bottles of the same size and shape water paper slips numbered 1 to 8 pencil Procedure Pour water to different levels in the bottles. Blow gently across the…
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 -…
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…
Simple Generator Experiment/ Make Simple DC Generator A motor can be used as a generator. A generator can be used as a motor. Materials motor, bulb, conducting wire and string. Science Both a motor and a generator are made of magnets and a coil. Watch related video: Make Simple DC Generator
Static Power, Static Electricity Science Fair Project Grade Levels: K-3 Background: When coal is burned in a power plant, small particles of pollution called soot are produced. Static electricity can be used to capture soot before it leaves the power plant. Question: Can a mixture of salt, sugar and pepper be separated using static electricity? Possible…
