These cool ideas for your science fair project can make you the winner!
SCIENCE FAIR PROJECT IDEAS FOR KIDS
- Rainbow Bouncy Eggs
An Easter favourite, the rainbow Jell-O eggs experiment is fun and safe for a science fair project idea for the kids. All a kid needs to do is fill half of the containers with vinegar and add about ten drops of food colour solution to each of these jars and place a raw egg inside them. After a sitting of 48-72 hours in the vinegar, the rainbow Jell-O eggs should be bouncing already!
SCIENCE FAIR PROJECT IDEAS FOR ELEMENTARY SCHOOL
One of the most popular elementary school science fair project ideas, you just need a few paper cups to get the project done. So you don’t have to go buying things with your monthly allowance or pester your parents to get the material for you. Also known as a Robinson anemometer, it uses cup-like shapes to catch the wind which makes the device spin. The number of times it spins within a particular time interval is, all you need to calculate how fast the wind is moving.
- Simple Electrical Circuit
Based on electricity, this science fair project idea for the 4th graders is quite a simple one. With a little guidance from an elder, you can make a simple circuit using a battery, a piece of wire and a light bulb. You do not need to buy anything extra, and moreover, the experiment is a safe one. Just take two strips of thin single-core wire, the kind that is used in a speaker or a stereo. Remove an inch of the plastic coating off the wire ends so that the copper metal is exposed. Attach the bare ends of the wire to the light bulb and the other ends to the top terminal of the battery to see it light up
- Steam-powered Rocket Boat
This is one of the most innovative and best science fair project ideas for 4th graders that can surely fetch you some accolades. The procedure of making the rocket boat, although meticulous, is pretty easy if you get a helping hand from a friend or someone older than you. And the best part? You are again going to get most of the materials for this project at home. To make this 4th grade science fair project, you will have to use fire to produce the steam, so we strictly recommend that you do this under parental/adult guidance.
SCIENCE FAIR PROJECT IDEAS FOR MIDDLE SCHOOL
- Splitting Water or Electrolysis
Ever wondered what would water look like if the molecules of hydrogen and oxygen were split up? If that intrigues you, then you should definitely try out this experiment to find out what happens when H2O splits up to into H and O2! This is an ideal middle school science fair project idea for the 8th grade, but the only problem with this one is that the experiment involves electricity and water. And therefore you need to be very cautious and must make sure that you do not touch the water while the battery is connected. Plus, we recommend that you do it under the supervision of your parents or someone older than you.
- Lava Lamp
For an 8th grade science fair project idea, the lava lamp is quite a simple and yet intriguing experiment that you can try. The approach is based on two scientific principles – density and polarity, and you can conduct the project using simple ingredients that you can find at home. All you will need is some vegetable oil and a food colouring solution from the kitchen, some water and a few Alka-Seltzer tablets to cause your lava lamp to erupt into activity.
SCIENCE FAIR PROJECT IDEAS FOR HIGH SCHOOL
- Solar energy panel
Creating an array of solar cells to construct a solar panel yourself is no less than a feat. Building your own cells out of gathered materials from scratch is an instructive activity thus making it the most winning high school science fair project idea. You are just going to need a sheet of copper flashing and some salt water to generate an electric current from sunlight that is enough to light a bulb. If you want to make the project more significant, then all you have to do is build a host of these solar cells and wire them in series. It is going to take a little effort and a lot of patience to get this done, but if successful, this science fair idea can win you a lot of appreciation and backslaps!
- Art with Magnetic fields
The one thing that we have heard since our childhood is that art and science are way different. But what if you could merge it? A great science fair project idea for 10th grade, you could create some beautiful patterns on paper by placing a magnet on a white sheet and sprinkling some coloured iron nails or shavings around it. The iron filings will trace the invisible magnetic lines made by the magnetic fields, and sketch colourful lines all across the paper making arty patterns. You can even use the lines to compare the power of different types of magnets.
SCIENCE FAIR PROJECT IDEAS FOR COLLEGE STUDENTS
- Zinc-air batteries
Considering how the quality of life on earth is degrading by the minute, constructing zinc air batteries as affordable and renewable energy storage is a good college science fair project idea that you may want to try out. You will need a zinc sheet, a blob of steel wool, two wires and a solution made of sodium hydroxide and water for the experiment. Since concentrated sodium hydroxide is dangerously corrosive, make sure that you wear a pair of chemical-proof gloves.
- Mobile Phone Detector
To impress your college professors, building a mobile phone detector can be a great science fair project idea. With a few materials, you can make yourself a mobile phone detector that can trace a phone call or detect activities on your mobile phone in the range of 1 meter. You are just going to need an LED blinker and a buzzer along with two 100nF capacitors which will work as a loop antenna and detect the RF signal emitted by a mobile phone.
