Science fairs are the best time when we can enjoy, study, and learn many things. As a 6th grader, I was very enthusiastic about the science fair, as we not only got to work on something creative but also loved watching different ideas of fellow classmates. We used to have exhibitions for the entire school, and watching some amazing experiments by the seniors and juniors was an outstanding experience. Our class teacher always told us what type of experiments we should take and how to perform them. The most important thing she used to tell was to select the one which we can understand, regardless of how easy or difficult it was. Clarity of the concept is a must. If you prepare a project with lots of complications, many data reports, a complicated model, a confusing graph, and a long explanation, then definitely the jury will have to put a lot of efforts to find out the concept behind the experiment. Whereas, if you take a simple experiment with a clear concept, a simple analysis with an informative explanation, then you are sure to be more confident and clear about your project. To help you out with this, we have some of the 6th grade science fair project ideas that will help you to select one according to your wish. Does an egg sink or float in water if the density of water changes? This is an interesting experiment for 6th graders. It requires very few common things which are easily available. So, let's check out the experiment. Things Required:

• 2 eggs
• Sugar
• Salt
• 2 large glass jars
• Water

Method: Take the jars and fill them with water. Now, place one egg in each jar and observe what happens. Now add a few tablespoons of sugar in one jar and salt in another. Again observe the changes and note them down. Explain the concept, experiment, and conclusion. Compare the results, or you can also make a comparison table which will be enough to explain the experiment. How does a volcano erupt? This is one of the most popular projects. It will include the volcano model, as well as show an actual volcanic eruption. Things Required:

• Baking soda
• Vinegar
• Clay/play dough
• Food coloring (red)
• Hard cardboard or plywood
• Plastic funnel
• Plastic water bottle

Method: Take all the required material and start with the project. Take the hard cardboard or the plywood and make boundaries so as to stop the overflow of the fluid at the time of the volcanic eruption. Now, take the plastic funnel in the middle of the plywood so that its wide mouth remains towards the plywood. Stick it firmly with the help of adhesive or tapes. The small openings on the top will become your crater. Now, it's time to give this funnel a shape of the volcano. Put clay or play dough all around the funnel and make a mountain, but do not close the top opening of the funnel. Now comes the part of the volcanic eruption. Mix approximately 7-8 drops of detergent with a pinch of red color. Mix this solution in about 500 ml of warm water. Now, pour this inside the funnel and fill it about ⅔rd. Add 2 tablespoons of baking soda in the same solution. Now, whenever you want to show the volcanic eruption you can just add vinegar from the side of the crater. As soon as the reaction between the baking soda and vinegar takes place inside the mix, the volcano will erupt. Do extreme fluctuations in climate affect the quality of rocks? The fluctuation in climate affects rocks. The water is soaked or absorbed by the rock in a liquid form, and when it is frozen the water molecules expand. This is the reason behind the breaking of rocks and rock slides. The experiment will show how the rocks get susceptible to breaking and what type of rocks are affected the most. Things Required:

• Different types of rocks like granite, limestone, and sandstone
• A plastic dish
• Water

Method: Take water in a plastic dish and place all the rock samples inside the container. Now, place this inside the fridge and take them out when the water freezes. Keep it in normal room temperature and let it thaw. Once it becomes liquid, again place it inside the fridge. Repeat the process 3-4 times and then observe which stone or rock was affected the most. Make a table which consists of the names of different rocks and their condition before and after the experiment is completed. You may also relate this experiment with the breaking down of huge mountains by the effect of natural fluctuation of climate. List of Projects

Other Science Fair Projects	Brief Description
Do plants grow better with music?	As we know, plants have life. They breathe, eat food, and are very helpful for sustaining life. But do you know that they understand music too? Yes, there is a lot of research which shows that music helps a plant to grow better and faster. So, find out the information and make an interesting project on it.
What causes tides?	Understanding the earth is one of the most interesting things for a 6th grader. The gravitational pull of the earth, sun, and moon makes tides happen. It will be a very interesting and fun project to do, as it will explain the reason, effects, and occurrence of tides.
How to make 2 liter bottle rockets?	Let's get into some physics. In this project, you will make a rocket out of a 2 liter bottle. The concept will help you to understand something about a rocket. It will be fun and you can also play with it once the project is completed.
What is the reason behind sweating?	This is actually a biology project. Sweating is a natural process that is conducted by our body to keep itself cool. The small sweat glands present on our skin's surface excrete water droplets, which come to the skin's surface and evaporate with the air. This cools down the body. Get a detailed description of this cooling down process of the body and make a project out of it.
What to do in a potato clock science fair project?	Do you know you can actually make a clock which works with the help of power generated by a potato? With the help of your science teacher you can actually prepare a clock which will work with the help of potato. Try out this interesting project.
What is solar energy and how it can be used?	Sun is a major source of energy, because solar energy is a non-exhaustible form of energy. You can make a project on solar power efficiency with the help of either solar panel models or by just showing the utility of solar energy. This project will help others to understand this form of energy even better.
How to prepare solar system projects?	There are eight planets in our solar system. These planets have their own identity and they all revolve around the sun. This project can have a lot of information. You can tell about the size, distance, composition, characteristics, etc., of the planets. It can use creative ways of representing the solar system model.
What causes tears while cutting an onion?	Tears while cutting an onion is a very common phenomenon. You can make a project with the help of the scientific or biological reasons behind its cause. This project will definitely help you to explore some interesting facts about the relationship between onion and tears.
What happens when you burn a candle at both ends?	Whenever you light a candle, its flames go up. But what happens when you light the candle from both the ends? Well, find out what happens and what is the reason behind it. You can really amaze your classmates and also help them to understand the behavior of flames. Take proper precautions while conducting and practicing this project.
How to create a tornado in a bottle?	This is a very simple project, with very few things required. You will be preparing a mini tornado in a bottle. But in this, you need to explain about the formation of a tornado and its disastrous effects. Don't forget to give reference about some of the most dangerous tornadoes till date.

The explanations to make some of the science projects given above might be available in your textbooks, or you can also discuss them with your teachers. I hope the information was helpful and you will definitely come up with something creative and innovative with the help of these projects.
