Cool and Easy Science Fair Projects for Students Doing Online Classes

Many schools consider the annual science fair the hallmark of science and engineering. In this event, students display their hard work in their independent science projects. They also answer any questions regarding their findings and projects and sometimes get recognized by judges. However, everything has gone virtual, including classes, discussions, and mentorship.

Consequently, your institution may not deliver the same in-person experience you've previously enjoyed. But the challenges don't mean you should ignore the entire science fair idea. You may achieve your desired results even in the virtual science fair by focusing on some cool and easy science fair projects for students doing online classes.  

Which Are the Cool and Easy Science Fair Projects?

Cool projects for online students mainly focus on soil erosion, water density, filtration, global warming, and geodesic domes. However, high schools can perform the more advanced stuff. Besides, online classes are different from physical ones; hence students need simple, easy-to-exhibit science fair projects.

What Are the Current Challenges Of Oline Education?

In the current post-pandemic era comprising hybrid and purely online classes, in-person science fairs are almost impossible. For instance, the current learning setup means not all learners will be available in school simultaneously. 

There are also reports of schools limiting learners from touching lab equipment, yet most need them for their projects. Finally, science fairs mainly comprise rooms filled with tri-fold boards that students use to present projects. But there are restrictions on how many people can use a classroom. 

The only way to overcome these hurdles is to develop a cool and easy science fair project. This way, you'll not have problems presenting your ideas and answering any questions from peers or professors. But one question lingers: What are some really cool science fair projects? 

What Are the Top 10 Science Fair Projects for Online Classes?

In this section, you'll learn some awesome science fair project ideas to inspire students to leave a lasting impression. Of course, a beginner's project is different from that of a competitive high school student. So we've arranged it to help you easily find something for different classes of young scientists.

Quick Science Fair Projects For Elementary Kids

Classic projects like stacking liquids to teach density or making a cyclone in a bottle can make a lasting impact. But what are some easy science fair projects for this category of online learners to engage with science uniquely? Here are some great examples. 

Cold or Hot Water Density Project

This simple process only requires some clear, same-sized containers, cold and hot water, and food coloring. Students will then add different colors to the hot and cold water and stack the openings above each other. If done correctly, the liquids with different temperatures will remain separate.

Water Filtration

Students can also use different materials to test water filtration. They can pour water through a mix of debris, rocks, charcoal, and sand and then filter it to demonstrate how clean it is. This simple science fair project for elementary students could supplement conversations about the water cycle.  

Soil Erosion in a Bottle

This easy project requires three clear soda bottles (cut in two), garden soil, and some plants with roots. The bottles will contain simple soil, a mixture of branches, rocks, and chunks, and growing flowers with roots, respectively. By pouring water through them, they'll see how plants retain soil.

The Best Science Fair Project Ideas For Middle School Kids

Middle schools can perform more independent science projects with a higher bar for creating and repeatedly testing a hypothesis. Students who analyze scientific data as a group can boost their verbal reasoning skills jointly. Here are some fantastic science fair projects for this category of scholars:

Geodesic Domes

This dome joins the arch as one of engineering and architecture's most robust physical structures. Learners can try different materials and design approaches to create a dome that can support as much load as possible. It could even carry the weight of an adult human being!

The Greenhouse Effect

Middle schoolers need a thermometer, jar, cellophane wrap, and a sunny window or heat lamp for this experiment. They'll then cover one jar and leave another open to demonstrate how the atmosphere traps heat to warm the planet. This will introduce them to climate and weather science basics.

Newton's Balloon Vehicle

Middle school students can put to the test Sir Isaac Newton's law that "every action attracts an equal and opposite reaction." They can experience this law by building a self-propelled toy car that leverages expelled air from a balloon. Even better, this experiment can be presented as a race.

Science Project Ideas For Kids In High School 

Science fair projects at this level should have nuanced and sophisticated analysis, design, and reporting. The students can be challenged to apply college-level knowledge in their projects since the fairs can grant them advanced academic placements and scholarships. Examples of such projects include:

Yeast, Enzymes, And Cheesemaking

While most people are slightly lactose intolerant, this shouldn't stop aspiring chemists and chefs from trying out this incredible project. Generally, students will test the chemistry behind tasty cheese using cheesemaking kits available online with the proper guidelines.


With the advent of advanced circuits, semiconductors, and 3D printers, never has there been a better time to learn robotics. Students can create a functional robot from scratch to address everyday problems, complete human tasks, or tell stories. There are endless possibilities with this!

Bioassay For Toxicity

Learners can test crops' resilience against extreme weather conditions like floods or drought. They could also test to determine the ideal salt concentration in soil for crops and the toxicity levels. Scientists fight climate change through environmental engineering, and high schoolers can propose solutions.

Electrolytes In Different Liquids

Numerous products sell because they promise to deliver electrolytes to the body, but which are the best options? Students can use an electrically charged wire to test the electrolyte level in liquids, from fruit juice to sports drinks. This single project helps them study nutrition science and chemistry.

Final Thoughts

What is the easiest science project for students studying online? Well, simple projects for online students may focus on concepts like water density, soil erosion, filtration, global warming, and geodesic domes. But those in high school can perform the relatively complex experiments mentioned above.

These science fair projects can help students interact with science and find solutions to everyday societal problems. So consider them for your next science fair.
