List of new science fair project ideas

Small volcano for science project

Very easy to make science project made by filling empty plastic bottle with 1/2th of bottle with vinegar

later adding spoon of baking soda well this gives white volcano which never occurs in real life

Make it look more like lava by adding some red food coloring

Finish the project by making it more realistic volcanic mountains using tissues followed by painting

Make small electromagnet

Materials used for this project are one steel nail, 9v battery and few inches of insulated copper wire

Wind nail with insulated copper wire with 20 to 30 turns

Remove ends of wire which is coated Connect ends of copper wires to 9v battery

Steel nail now is an electromagnet, check it out by keeping iron particles around it

Balloon car science fair project idea

With few pieces of cardboard and old plastic bottle caps make easily movable car frame

Straws will help you in making wheel axles

To make moving mechanism just blow the balloon and close its ends with help of cloth pins Keep it on backside of car

Place in such a way that balloon air releasing end is facing opp to movement of car

Remove cloth pins and watch your air powered car move

Windmill for science fair project

One of evergreen topic for science fair

Materials used are small toy dc motor, led, battery and few pieces of cardboard, Make propellers for windmill and attach it to dc motor shaft

Place it on top of cardboard frame Connect dc motor to battery and led bypassing switch. Switch on and see working of your windmill

Electricity Generator project

Needed supplies are 2 DC Motors, battery, switch and LED

Recycled motor from old RC car or other toys works fine Connect one DC motor to LED

Shaft of Motor will be connected to other motor shaft using coupler recycled from pen

Place everything on piece of cardboard and hot glue to keep everything in place Connect vacant end of motor terminals with switch and battery

when u switch on motor shaft of other motor rotated hence electricity will be generated which can be seen by glowing LED

This works on electromagnetism principle

Solar car project idea

Supplies required are 150ma 6v solar panel, DVD motor, 3 wheels and triangular cardboard frame

Connect wheel to shaft of dc motor then Fix wheels on base side of triangle

Tip of triangle to body of motor and Connect small solar panel to motor

Take it to sun bath! you can Enjoy your solar car travel

Hand powered battery less torch

LED bulbs up-to 10 can be light up you Need 775 DC motor or DVD motor and LED

775 DC Motor works best for this project as it generates good output voltage on shaft rotation

Make frame for torch using old recycled water bottle which fits motor start by Soldering LED to motor

Shaft of motor to bottle cap to which small stick is attached that resembles crank shaft mechanism

Rotate dc motor shaft and see the bulb glow here Note that faster rotation generated up to 12v hence slow rotation is preferred

Automatic pencil sharpener

Tired of sharpening pencils by hand this project carries solution for that problem

You need BO motor or any other low rpm gear motor I used 150rpm gear motor

Attach pencil sharpener to shaft of geared motor

Connect to battery via switch Switch on and sharp some pencils

Definitely you will enjoy the process

Small handheld Fan project

scavenge toy dc motor from toys

stick motor to back side of battery

Use switch as interface between motor and battery

Attach readily available propeller or DIY

Power your device and let some air flow

Lemon battery science fair project

Oldest yet meaningful science project which teach lots of scientific principles

Here to glow an led number of lemons required is high since lemons are costly we will demonstrate with single lemon

Insert strips of zinc and aluminum inside lemon

Connect multi meter to these strips and measure voltage
