Science is essential to understand the natural world. It encompasses many topics, such as astrophysics, astronomy, biology, mathematics, history and latest technologies. With science fairs, students will understand how the universe works. During the science fairs, students are able to collect information, ask questions, make observations and perform experiments. There are new discoveries that can bring understanding and improvement in our quality of life. With science fairs, it should be possible for students to understand the whole and they could have a desire to become scientists. It is human nature to make a lot of questions and we should be aware of things that happen around us. Science exercises should be essential to ensure that students can implement when they have learned in the classroom. There are laboratory works and hands-on activities that students could do during science fairs. Science fairs should also offer interactions between pure science with technology and society. If students want to participate in the science fairs, they should choose topics that they are familiar with. As an example, students may choose insects and other animals as the primary focus. Students may show in an interesting way interesting things about animals, such as how the communicate and eat to survive. There are different characteristics and traits of an animal that people will find it interesting. Students may choose a few exotic animals with unique life cycles and behaviors. People could be impressed with how these animals live and students should provide enough information.
Astronomy is also an interesting thing that we may share to others. There could be specific stars, planets, asteroids, planetoids, galaxies, nebula and other distant objects that students want to focus on. Students may also provide interesting facts about how extraterrestrial life may exist based on facts on Earth. We may also show how solar energy works and how it can be harnessed. Human body is a complex biological machine and it could become a subject of science fair. We should show people how our body reacts to external factors and good. We may show how nutrients could be beneficial for our body to sustain growth and prevent disease. Earth is a planet where we live in with so many interesting things. Volcanoes, streams and oceans are interesting subjects for science fairs. We should be able to provide people with an information how the ocean and weather interacts with one another. Water cycle is a commonly known fact, but it can still be shown in an interesting way. We could show how the Earth surface would be like when the North and South poles melt partially and completely. We may also show how the continents would look like in two billion years or more from today. Gardening and plants are another subjects that we can choose for science fairs. We could show others how photosynthesis works and why it is critical to life on Earth, even to carnivores and human. Another idea is to show how types of soil works with a specific type of plant. We could also show the percentage of water in different fruits, including showing fresh fruits and completely sun-dried fruits.
