What Are The Best Science Projects For Kids?


Science is a discipline in a STEM curriculum that outlines information based on verifiable facts and logic through experiments—grouped into chemistry, physics, and astronomy.

Science projects are activities carried out to support, refute, or validate some science facts or logic by analyzing the experiment results. They are mainly grouped into experimental, engineering, display, and theoretical.

Kids at an early age may not be able to connect what they learn in science with real-life happenings, which is made easy through performing various science projectsbased on their age groups.

2-5 years

This age group mostly learns through playing, and its great if you let them perform the following projects even if they repeat the same thing several times. They have a better understanding of the passing time and an improved memory.

  • Lemon battery

Lemon battery, similar to the first electrical battery invented in 1800 by Alessandro Volta, used saltwater instead of lemon. Two different metals are used as electrodes when inserted in the lemon one collects excess electrons. In contrast, the other metal loses electrons, and this positive and negative flow of electrons creates an electric charge.

The kids should enjoy making the battery out of a fruit, which generally turns chemical energy into electric energy enough to power a small LED light. It will help them understand phenomena such as oxidation and reduction. Kids should try using other acidic foods such as orange and potatoes.

  • Magnetic car

A magnetic car project is a creative way of explaining magnetism to kids. It involves a car and three magnets where two of them are connected to the car while the other is used to control the car by the toy car’s driver.


  • Smartphone projector

It’s not enjoyable to watch cartoons and movies on a small screen such as smartphones; therefore, for kids to enhance their creativity, they can make their smartphone projector.

A projector is an optical instrument used to create a large picture of a small image into a surface. This is commonly achieved by shining a light through a small transparent lens, but the current technology of applying lasers used in newer projectors produces image direct.

The project will help the kids greatly understand the basic operation of a projector, majorly how a convex lens works in magnifying the image.

The kid may use different lenses to understand how they focus light and affect the image’s quality.

  • Make hydraulic crane

This is a type of heavy-duty machinery in lifting heavy things such as on the harbor. It has a heavy hydraulic system generating a large amount of power, which allows the equipment to lift heavy things. It is easy to use and maintain as it contains fewer moving parts.

It’s a great project for kids as it is inexpensive to make and most useful in explaining the principle that any force applied to an incompressible fluid will propagate entirely without loss significant loss of strength to affect whatever is on the other end.

Through the experiment, kids can develop a norm of thinking on easier ways of undertaking tasks.

6-9 years

This an age-group where kids become more independent and creative. You will always meet them trying new things to satisfy their eagerness, and in the process, you will meet them to spend most of the time with their toys. It would be very substantial, letting them try out these science projects for their development:

  • Make the solar system.

The solar system consists of the sun, earth, our home planet, other planets, and any other object that revolves around the sun, such as comets and asteroids.

By making the solar system, the kid will better understand the milky way galaxy by knowing the eight planets with their names and differentiating their sizes. They will also get to know the planets that near-earth and round objects moving around (orbiting) the sun. This would paint a clear picture of the solar system compared to theoretical knowledge of the same.

  • Hydraulic Elevator

The elevator works in accordance to the pascal’s law which isa principle in fluid mechanics established by a French mathematician Blaise pascal in the year 1647 which state that when there is the change in pressure at any point of a confined incompressible fluid (usually an oil of some sort), there is an equal chance at every other point in the container.

It’s easy to make as it’s built out of popsicle sticks and syringes.

This project is used in physical science (force and motion) to demonstrate to the kids how a small pressure inside a confined fluid can exert enormous pressure on the walls of the used container, which in our case, is a syringe.

  • Space rocket

Rocket is a spacecraft, aircraft, missile, or any other device thrust from a rocket engine. In its simple form, it’s a chamber enclosing a gas under pressure. This project involves the creation of rockets and launching them into the sky. When the kids do this project, they are free to try launching their rockets at different angles, hence analyzing the effect on the distance covered by the rocket. It’s a good example to elaborate Newton’s Laws of motion to kids. When the rocket stays still until acted upon by force, it’s obeying first law, and when it uses more force (fuel) to launch a larger rocket, that is the second law.

  • Egg Car

This is a project to design a car to protect raw eggs during transportation. This is used to explain the newton’s second law. It can also be used to introduce gravitational force to the kids, which is an important force in the world of science.

10-13 years

Kids in this age group are enthusiastic, and they grab new things much quicker and are good at working in groups. They can easily tell the differencebetween right and wrong quite well, making them a great group to undertake more risk activities such as a fire.

  • Solar oven

To curb their hunger for creativity while teaching kids ways of concentrating solar energy and experimenting with different scientific phenomena such as reflection, convention, radiation, and terms such as insulation and thermal energy, then making a solar oven is a great project them to undertake.

A solar cooker is a device used for cooking or warm food through heat generated from direct sunlight. They are relatively inexpensive for you don’t incur any cost at fueling them and reduces one’s carbon footprint which makes them likely to be mainly used shortly as environmental conservancy agencies are advocating for their use worldwide since they involve no air pollution and reduce deforestation since 2.5 billion people cook on an open fire using biomass fuels.

  • Make a Microscope

The microscope is an optical instrument invented by Zacharias Janssen around 1590, which magnifies small objects such as animal or plant cells several hundred times, resolves the object’s details, and makes these details visible hence making it visible to the unaided eye.

Kids should perform the project on making their microscope, which will not only make them happy and satisfied as inventors but also enable them to understand the ideas of magnification, refraction, reflection from specimen, resolution, and light transmission, which are major concepts under the working microscope.

  • Making a drawbolt

A robot is a device that is created to perform a complex series of tasks automatically. It can be controlled remotely, or the control is embedded in the system. A computer especially programs them.

Drawbot project, which involves making a robot that moves around drawing a path wherever it goes, is too appealing to the kid’s young creative minds.

The kids will be able to make and operate their robot, build a simple circuit involving a motor and explain how it works,  be able to identify conductive materials and explain the role of conductivity as while as understand how energy change from one state(mechanical, kinetic, potential energy) to another.

  • Roller-coaster

This is a type of a fascinating ride found in parks that make use of elevated railroad tracks designed with tight turns, steep inclines, and a times inversions. The first one was in Coney Island, which was opened in 1884. They are becoming better each day due to the competition around the parks in the entire world where each park wants to be famous for its high roller-coasters such as cedar point park known for having the first coaster to go over 200 feet, 300 feet, and 400 feet.

The kid who does the project is better positioned to understand kinetic energy and potential energy in practice as the coaster starts flying up. It’s said to gain kinetic energy and loses potential (magnetic, electric, elastic) energy.

It can also be used to explain phenomena such as centrifugal force and the law of inertia all experienced in the seat one sits on in the roller-coaster.
