1. Model of the Solar System

A science project that can help kids and teens to understand the different planets that make up the Solar System is to make a model of the Solar System. This project is usually done by using a Styrofoam ball or a large balloon to represent the sun. Then, using clay, paint, or small Styrofoam balls, each planet is created and placed in the correct order around the sun. This project can be modified to include the inner planets and the outer planets. It can also be used to explain the order and distance between each planet.

2. Create a Volcano

Creating a volcano is a classic science project that can be used to explore chemical reactions. An empty two liter bottle is filled with baking soda and vinegar. When the baking soda and vinegar mix, a chemical reaction takes place and causes a volcano-like eruption. This project can be modified to explore different types of chemical reactions.

3. Plastic Bottle Ecosystem

This science project can be used to help kids and teens understand ecosystems, or how living and non-living things interact in an environment. A two liter plastic bottle is filled with soil and different types of plants and animals, such as rocks, dirt, worms, and grass. The bottle is then sealed and placed in a sunny spot. Over time, the plants and animals will interact with each other to form an ecosystem.

4. Make a Cloud in a Bottle

This science project is a great way to explore the science of clouds. A two liter bottle is filled with warm water and a few drops of food coloring. Then, a cotton ball is inserted into the bottle, and the lid is screwed on tightly. When the bottle is shaken, the cotton ball will expand, creating a cloud like effect. This project can be modified by exploring different types of clouds and the conditions that cause them.

5. Create a Solar Oven

A solar oven is a great way to explore the science of heat and energy. This project requires several materials, such as a cardboard box, aluminum foil, and a plastic bag. The cardboard box is lined with aluminum foil and the plastic bag is placed inside. Then, the box is placed in direct sunlight and the food or drink is placed inside the plastic bag. Over time, the heat from the sun will cause the food or drink to heat up.

6. Build a Robot

Robotics is a fascinating area of science that can be explored through this project. Kids and teens can build a robot using items such as cardboard, aluminum foil, and buttons. Then, they can program the robot to move and respond to commands. This project can be modified by exploring different types of robots and programming languages.

7. Make a Compass

A compass is a great way to explore the science of magnetism and navigation. This project requires several items, such as a needle, a magnet, and a piece of string. The needle is magnetized by placing it near the magnet. Then, the needle is placed in a bowl of water and the string is tied around the needle. Finally, the needle will point in the direction of north.

8. Create a Model of DNA

This science project can be used to explore the structure of DNA. A model of DNA can be created using items such as pipe cleaners, paperclips, and beads. The pipe cleaners, paperclips, and beads are used to represent the different components of DNA. This project can be modified to explore other biological molecules such as proteins.

9. Build a Wind Turbine

A wind turbine is a great way to explore the science of energy and the environment. This project requires several items, such as a motor, propeller, and blades. The motor is attached to the propeller and the blades are attached to the propeller. Then, the wind turbine is placed in a location where it can be exposed to wind. When the wind blows, the turbine will generate energy.

10. Make a Water Filter

This science project can be used to explore the science of filtration and purification. A water filter can be made using items such as sand, gravel, and charcoal. The sand, gravel, and charcoal are placed in a container and then water is poured through the filter. The water will be filtered and purified as it passes through the filter. This project can be modified to explore other filtration methods.
