Science fair project ideas for fourth graders 1. **Volcano Eruption:** Create a miniature volcano using clay or papier-mâché and use baking soda and vinegar to simulate an eruption. This project can help students learn about chemical reactions and geology. 2. **Magnetic Slime:** Make slime using school glue, borax, and iron oxide powder. This slime will be attracted to magnets, demonstrating the principles of magnetism and polymer science. 3. **Solar System Model:** Construct a scale model of the solar system, showing the relative distances and sizes of the planets. This project can help students understand astronomy and mathematics. 4. **Plant Growth Experiment:** Investigate the factors affecting plant growth, such as light, water, and soil quality. Students can grow beans or other seeds in different conditions and measure their growth. 5. **Electric Circuit:** Build a simple electric circuit using a battery, wires, and a small light bulb or motor. Students can learn about electricity, circuits, and conductivity. 6. **Ocean Currents:** Create a model of ocean currents using food coloring and water. This project can help students understand fluid dynamics and oceanography. 7. **Sound Waves:** Investigate how sound travels by creating a simple telephone using two cups and a string. Students can learn about sound waves, vibrations, and communication. 10. **Renewable Energy:** Build a small wind turbine or solar panel to generate electricity. Students can learn about renewable energy sources and sustainability. When working on these projects, it's essential to follow safety guidelines and seek adult supervision when necessary. Encourage students to ask questions, make predictions, and record their observations. They can also present their findings in a creative way, such as a poster, a PowerPoint presentation, or a video. Remember, the goal of a science fair project is not only to demonstrate scientific concepts but also to inspire curiosity, creativity, and critical thinking. By working on these projects, fourth-grade students can develop a lifelong love for science and discovery. 5. **Electric Circuit:** Build a simple electric circuit using a battery, wires, and a small light bulb or motor. Students can learn about electricity, circuits, and conductivity.
