Getting promoted to the 7th grade is fun for students because they are then officially allowed to handle wet lab experiments. And I can bet on the fact that students impatiently wait for their practical sessions as they break the monotony of theory classes. Science fairs are organized by schools, which further give them the opportunity to exhibit their skills and knowledge. Students are enthusiastic about organizing science fair projects and presenting their innovative ideas in a structured manner. Ideas for Science Fair Projects for 7th Graders Basic knowledge in the core subjects, i.e. physics, chemistry, and biology is required to bring out the best project work. Take guidance from your teachers if you have doubts in the experimental procedures. You are also supposed to be aware of the lab safety guidelines while implementing a science fair project. Choose the subject in which you have keen interest and come up with new ideas for the science fair. Being a 7th grader you are not expected to invent something, but you can definitely channelize your efforts towards performing and presenting the experiments with perfection. The topic ideas are enlisted below. 1. Demonstration of Archimedes principle of buoyancy. 2. Presenting the model for balloon aircraft. 3. The experiment to prove the laws of motion. 4. Measurement of electricity through electric circuit. 5. Depicting composting through microbes. 6. Conduction of electricity through salt water. 7. Representing the phenomenon of anomalous expansion of water. 8. Demonstration of photosynthesis. 9. The phenomenon of rusting in normal water vs salt water. 10. How do volcanoes erupt? 11. Quantity of salt required to make an object float. 12. The cleansing action of detergent on clothes and the mechanism behind it. 13. What is Oobleck and what is the best formula to define it? 14. Formation of images in television. 15. The effect of temperature on growth of caterpillars. 16. The capacity of lungs according to age. 17. How do rays pass through a prism? 18. What is the difference between LED lights and incandescent lights? 19. Depicting the process of artificial fruit ripening. 20. Does caffeine affect the growth process of fruit flies? 21. Presenting a model of human heart and its functions. 22. How do an electromagnet act? 23. Do honey bees communicate with each other? 24. Formation of fizz inside aerated bottles. 25. An artificial model of solar system. 26. Does water evaporate faster under a bulb? 27. Effect of UV light on growth of bacteria. 28. Is caffeine a good pesticide? 29. Demonstration of Lavoisier's Experiment. 30. The static action of dog saliva on bacteria. 31. Growth of radish plant in the presence of magnet. 32. Demonstrating the framework of human skeleton. 33. Conduction of electricity through vegetables and fruits. 34. The physical process of evaporation and combustion. 35. Making a musical rat maze. 36. Artificial craters and depicting the process of formation. 37. Demonstrating the relativity of slope quotient with erosion. 38. The methods of seed testing. 39. Effect of temperature and water on the process of germination. 40. Effect of medicated water on growth of Daphnia. 41. Does combustion of wood depend on the nature of species? 42. Demonstrating the solar heater or solar energy of sun. 43. The ways to utilize recycled waste. 44. Effect of food preservative on foods. 45. Effect of plant hormones on growth of plants. 46. Flame testing for specific elements of the Periodic table. 47. How tides are formed? 48. Demonstrating the phenomenon of plasmolysis. 49. Demonstrating the capillary action of plants. 50. Representing the topology of earth. Form effective groups and help each other to put up an experiment that is scientifically correct. A well-coordinated science fair will definitely be a huge success for the school at the large.
