They are designed to excite young minds and help them understand the nuances of science, in its myriad forms. Many of the projects end up winning prizes for their ingenuity and innovation. These projects are also highlighted at the national level, thereby motivating, and inspiring many more.

In this article on winning science fair projects, we will look at some of the science projects that have been able to make a mark at school science fairs.

1. The Tardigrades

This is a Primary school Grade K-3 project talking about the miracle that tardigrades are. Samples of moss and lichens were taken and soaked for 24 hours. These were then analyzed for the detection of Tardigrades.

Once detected, the samples were submerged at -5 degrees centigrade for an hour and checked again. They did survive the conditions.

2. The reality of sock monsters

This Garde-K3 experiment was intended to understand human psychology and behavior better. It also involved a wee bit of electricity. A washing machine was allowed to wash 10 pairs of socks, with and without another laundry. The socks without laundry were found to be stuck to the drum of the machine whilst the rest, were with the other laundry. Oh, yes, there wasn’t a hint of the sock monster.

3. Thirsty Flowers

Another path-breaking Grade- K3 project was to ascertain the manner flowers drink water. To complete this project, white carnations were arranged and placed in a beaker of blue water, while other flowers were placed in a beaker with no colored water. The conclusion was that flowers are indeed thirsty and hence they drink water.

4. Trees Vibrate

This high school science project showcases the way trees vibrate or if at all. The setup involved two magnets, four coils (two types), piezoelectric material, a metal cantilever beam, a circuit, an agricultural measurement module, a plastic structure, rechargeable batteries, a gear system, and a transmitter. The conclusion was that trees do vibrate.

5. Sugar from Food Waste

Another award winning science fair project aimed at finding out whether food waste was a great substitute for substrates in MFCs or Microbial Fuel Cells. Banana peel turned out to be the best replacement for current substrates.

6. Harvesting transparent and flexible energy using Bi-Layer Graphene

This high school science project aims to eliminate the lack of electricity, plaguing large parts of the planet by using bi-layer graphene. The result of the project was impressive though it was also ascertained that this method may not be suitable for the mass production of electricity and would need a tweak if it was to become a success on a large scale.

7. Averrhoa Bilimbi

This is a fruit and high school project handlers want it to be a rubber coagulant. At an experimental level, it was found that the weed plant Averrhoa Bilimbi is also popularly known for easily coagulating rubber better than formic acid. The future scope of such a method is immense.

8. LeafAI and Plant disease diagnosis

CNN or Convolutional Neural Network has become a powerful tool in the world of machine learning. They can be used to analyze large-scale changes in agriculture. The planet model acquired 95% accuracy in its reading while analyzing plant diseases.

9. Waste Reduction

An important 1st-grade award-winning science project that aims to reduce waste, beginning with the ones produced at the school premises. The foremost step towards analyzing the waste was to categorize them and it was found that a lot of them could be recycled. Recycling helps reduce the burden of waste on the planet.

10. Cracks in the Earth

The planet Earth is a wonderful place but a mysterious one too, with plenty of geographical and geological wonderments. This Primary school project aimed to define what caused fractures and what the geological faults were. It also wanted to see whether similar factors be replicated on a cheese.

11. Which side of a leaf takes in Carbon Dioxide

This primary school award-winning science project wanted to identify the side through which gas exchange takes place in a leaf. We call that small pore stoma. The stomata are responsible for the entering of oxygen and the release of Carbon dioxide.

12. Food coloring and plants

Food coloring has had its role in affecting symptoms of ADD and ADHD negatively. The primary school science project involved adding food coloring to the irrigation of a bean seed experimental set and then the growth and development of the same set were measured as compared to the ones which did not have food coloring added. The experiment concluded that both growth and development were stunted.

13. The Aerodynamic Lift

This sixth-grade award winning science fair project aimed at studying the aerodynamics of wing shapes using different model planes, two heavy cardboard boxes, an electric box fan, a plexiglass sheet, a digital scale, and Lego blocks. A wind tunnel was constructed to analyze the lift capacity of the plane vis-à-vis its weight, and it was ascertained that its lift of it was directly proportional to the weight it carried, and thereby the shape of the wings needed to be modified as per the requirements.

14. Nanospheres and the endeavor to produce energy

This high school project aimed to check the applications of europium-doped yttrium oxide (Y2O3:Eu3+) nanospheres in the lighting industry. The conclusion of the experiment suggested that the nanosphere was indeed more efficient and would have a positive impact on solid-state lighting technology.

15. Stray Dog Vaccination using Machine Learning

Homemade water filter science project

March 6, 2022 by ScienceProjects

Homemade water filter science project

Objective

Let us today make our Homemade water filter science project or water filter paper using scientific techniques. This will be one of the funny science experiments in which dirty water turns clean. With soap, no way! You’ll need a filter, which is a device that eliminates pollutants like dirt from water. The Homemade water filter science project you’ll make here with an adult’s guidance who can help you up in your experiments.

Material required for Homemade water filter

● 2 liters empty and clean plastic bottle

● Knife

● unclean Water (make your own with things like coffee grounds, dirt, shredded old leaves, cooking oil, or small pieces of foam)

● Cup for measuring

● Spoon

● a stopwatch or a watch.

● a pencil and some paper

● You may acquire as much activated charcoal, gravel, sand (coarse and/or fine), and cotton balls as you like.

● A bandana, old sock, handkerchief, or even a paper towel can be used as a coffee filter.

Homemade water filter Procedure

Step 1 Request that an adult cut the bottle in half. Then, to make the top seem like a funnel, flip the top half of the bottle over and set it down. At the top, you’ll create your filter.

Step 2 at the bottom place the coffee filter (or bandana, socks, etc.).

Step 3 Cotton balls, charcoal, gravel, sand, and/or other materials should be included in the layers. You can choose to use just one or all of them. Consider which sequence you want to add things within. Larger filter materials, on the other hand, are more likely to collect larger pollutants.

Step 4 Make a list of the filter materials you used and the sequence in which you stacked them.

Step 5 Measure one cup of unclean water after shaking it.

Step 6 Set your timer

Step 7 Fill your filter with a cup of filthy water. As soon as you begin pouring, start the timer.

Step 8 How long does it take for all the water to pass through the filter? Then write down how long it took.

Step 9 Remove the filter material one layer at a time with care. What did each layer take out of the water?

Step 10 Experiments! Try again after cleaning the bottle. Each time and at the time of each experiment, arrange the filter material in a different arrangement. Hopefully, you enjoyed the whole experiment and enjoyed your filter paper.

Observation

In the Homemade water filter science project experiment, you will observe that the water which you has earlier was polluted and had many particles of dust, sand, etc particles but when you have passed that water from your homemade filter the water you got was clean, and the dust and sand particles were collected by the filter.

Conclusion

The slower the better! Water becomes clearer when it passes through a filter for a longer time. Water passes through the filter material quickly, but big pollutants like dirt are trapped. Filter materials are often finer and thinner, allowing them to collect anything that had previously gone unnoticed. Activated charcoal, which employs an electrical charge to collect extremely minute particles for humans to see, may be found at the end of the water route.

Your filtered water is not safe to consume. However, a plant will adore it. So do not drink it you may pour it into your plants.

Result

Hopefully, you have made the Homemade water filter. The water cleaned by this filter will not be good for drinking as it does not kill germs but it removes dust and sand particles. You may use this cleaned water to pore your plants.

Wind turbine science fair project

March 6, 2022 by ScienceProjects

Wind turbine science fair project

Wind power is a renewable form of energy. It is very cost-effective and can be used to perform multiple tasks. Generally, wind turbines are located at higher places or near the sea. Wind turbines are energy efficient and can convert 20 to 40 wind into energy. It is a pollution-free way to generate energy. In simple terms, a wind turbine can generate mechanical energy. You will be shocked to know that Wind energy is also coming from the sun. Sun is the ultimate source of energy and, wind energy is no exception to it. The land heats up faster than the ocean and, because of this, Hot air moves upwards, and cool air takes its place. This movement is known as wind. This movement of hot and cold air is known as the convention.

A wind turbine has five significant parts.

These five significant parts are base, nacelle, rotor, tower, and generator.
When the wind blows, it spins the blades around the rotor and, then it also rotates the generator.

Objective

The objective of this project is to find how wind energy works? This experiment will help you to understand the basic understanding of how a wind turbine works.

Theory- To prove that a wind turbine generates mechanical energy and electrical energy.

Abstract

Sustainable energy sources are the need of the hour. Wind energy is a sustainable and renewable energy source and, it can generate electricity too. Wind power also comes from the sun. A wind turbine converts wind’s kinetic energy into mechanical energy. When wind touches the turbine blades, it starts rotating. Rotation of the blades turns the turbine. It also moves a drive shaft connected with the generator. The generator turns on and starts generating electricity. Turbine blades and wind speed also play a significant part in this.

Procedure

Material for the Project Experiment- Small electric motor, Cardstock paper, fan, Pencil with eraser, Straight pin, Ruler, insulated copper wire, 1.5-volt bulb, and bulb holder.

Preparations- Take the cardstock paper and cut a 4 feet square.

Experiment

1. Now, take a ruler and draw diagonal lines from one corner to another. Cut the diagonal lines till you are 3/4 inch away from the center of the square.
2. Now, Fold and pin all the layers with each other with the help of staple pins.
3. Now, take a straight pin and pin all four blades into the eraser. Pinwheel is ready.
4. Place this pinwheel in front of a fan and watch them spin.
5. Take out the pinwheel and connect it to the motor shaft. Try using masking tape for a better fit.
6. Take an insulated wire and connect the motor wires with the bulb.
7. Now, again place it in front of the fan. Your bulb will start glowing.

Observation

When placed in front of a more strong fan, the light bulb glows brighter and, it also confirmes that electricity is being generated from wind power. The amount of energy also depends on the size of the pinwheel. The wind power can also be measured by a digital multimeter. A multimeter can easily measure energy.

Conclusion

When we place the pinwheel in front of a fan, it starts spinning which, is a form of mechanical energy. This mechanical energy got converted into electricity with the help of a motor. This experiment proves that wind carries mechanical energy which, can also be converted into electrical energy. Wind energy depends on the blade length and turbine size. The strength of the wind is also substantial for generating electricity. If we increase the wind strength two times, the wind power increases eight times.

Magnetic Fields experiment

March 6, 2022 by ScienceProjects

Magnetic Fields experiment

MAGNETIC FIELD

Magnets offer an introduction to attraction and repulsion, and to act at a distance (magnetic field) and we will see the Magnetic Fields experiment below.

OBJECTIVE

The objective of the Magnetic Fields experiment is to investigate whether one magnet will expertise and exert each attractive and repulsive force with alternative magnets or not. And as we know magnetic fields are invisible, but with this activity, we can see the appearance of magnetic field lines.

APPARATUS

● Magnets, different types (at least 2pairs)
● Nails
● Iron filings in a pepperpot
● Compasses
● Other materials for testing magnetic behavior
● Small scraps of paper
● Sheets of papers
● A pen or pencil

Magnetic Fields experiment PROCEDURE

Whether one magnet will expertise and exert each attractive and repulsive force with alternative magnets or not.

● Hold pairs of magnets and feel the forces between them, repulsions in addition as attractions.

● Use the magnets to undertake to draw in nails and alternative materials. a number of them (such as little scraps of paper) cannot be attracted by a magnet.

● Place a magnet beneath a bit of paper and scatter iron filings on prime to reveal a magnetic field pattern. The aim of the sheet of paper is to stop direct contact between magnets and filings since they will be laborious to separate. faucet the paper gently to make sure the filings don’t stick together.

● Place compass needles tip-to-tail close to a magnet.

● Record their directions, to plot the magnetic field as constant fieldlines.

● Suspend a magnet and show it aligns roughly North and South. The pole that points North is the “North-seeking pole” of the magnet.

We know magnetic fields are invisible, but with this activity, we can see the appearance of magnetic field lines.

● Place the bar magnet in the middle of the paper. Trace the outline of the magnet – that way you can put it back in the exact same spot if it gets bumped.

● Place the compass at one pole of the magnet and make a dot next to it showing the direction the compass arrow points.

● Move the compass so that the base of the arrow is at the dot you’ve just made. Now make a new mark where the tip of the arrow is pointing this time.

● Keepdoingthisuntilyoureachtheotherendofthemagnet.

● Connect the dots. You’ve just drawn one magnetic field line!

● Go back and begin again, starting at a different spot than you did the first time. Repeat the above steps.

● Repeat the process until you have drawn as many lines as you can for both ends of the magnet. You will now have an accurate representation of magnetic field lines.

● Different magnets will give you different field lines. Try repeating these steps with magnets of different sizes and shapes.

● You can also “draw” field lines with iron filings, available at most hardware stores. Use the same magnet and paper (with your drawn field lines) from the above activity. Put the magnet back in place under the paper, then sprinkle the filings on top. Tap the paper gently.

OBSERVATION

In the above Magnetic Fields experiment, we observed that one magnet will experience and exert each attractive and repulsive force with different magnets.

It permits the introduction of the thought that magnets have 2 completely different ends or faces, known as poles.

And we can observe that filings fall into place along the very same lines you drew.

CONCLUSION

The Magnetic Fields experiment thus proves that magnets have 2 completely different ends or faces, known as poles and they create magnetic fields. As we know that we can see the magnetic field lines are invisible, but with this activity, we have seen the appearance of magnetic field lines.
