Science is considered as one of the difficult subjects including both theory and practical application. Students of Class 7th learn to make working models and understand it’s applications. There are various science projects for class 7th students that are given by the teachers. Students are allowed to make a group of 3 – 5 members to coordinate accordingly and make the model. These models are in a form of the diagram that the students must have seen as a kid in various commercials.  


The students working together develop skills like teamwork, leadership skills, synchronization and much more. These skills help the students in the long run for other future prospects. These scientific models somehow explain the behaviour of the systems in the real world i.e. how do they react to natural calamities or how are they made and used. 


These models are made to make the concepts easier. Students understand whatever they have learnt in the classroom lectures through creating these working models. Students enjoy making such models with an understanding of interesting facts from subjects like Physics, Chemistry, Biology, Earth and many more. Below are some of the working models that students make in order to simplify the concepts of science. 


List of Science Working Models for Class 7th 


There are various models provided to the students so that they can understand and learn various difficult concepts. Below is the list of some science models that students are given.


  1. Water Turbine Project
  2. Vacuum Cleaner Project
  3. Hand Generator Project
  4. Windmill Project
  5. Pinhole Camera Project
  6. Potato Battery Project
  7. Periscope Project
  8. Motorized Windmill Project
  9. Biodiesel Project
  10. Solar Cell Project
  11. Cotton Candy Machine
  12. Wind Turbine Project
  13. Working Model of Heart
  14. Biogas Plant Project



These are some of the winning science fair projects for 7th grade. Students can learn and explain to their team members or peers about how the model works and what it represents. These models are a part of exams and students are evaluated in the exam based on this project.      


Science projects for class 7th working models


There are other working models too apart from the ones mentioned above. These science projects lead to a better understanding of various theoretical concepts. Below are some other projects that students might be willing to make. 


  1. Small bar magnets
  2. Motor model kit
  3. Vegetable battery kit
  4. Wind energy house
  5. Simple Solar House
  6. Wind Energy House
  7. Solar System
  8. Eclipse Models
  9. Hydropower House
  10. Automatic Street Light Model
  11. Rain Harvesting Model
  12. House with Burglar Exam
  13. Solar Street Light Model
  14. Automatic Water level Controller model
  15. Rain Alarm with house
  16. Wind City Model
  17. Industry with Solar Power
  18. Dam working model
  19. Hand Generator Model with Bulb
  20. Electric Bell Model Kit
  21. Energy from Waste
  22. Eye Model
  23. Brain Model
  24. Ear Model
  25. Urinary Model
  26. Blood Circulation in Human Body Model
  27. Plant Cell


These are some of the science projects for Class 7th in science exhibition. Students can take part in various science competitions and exhibitions and win several prizes.   


Working Model of Science for Class 7th 


There are several other working models in science that are easy and understandable. These models include:


1. Greenhouse Effect:


This model is made by the students to depict how various gases and other surfaces traps the heat and leads to the depletion of the Ozone layer that results in increased pollution. This experiment shows the effect of the greenhouse on the environment. 


2. UV Protection:


UV Rays are harmful to the human body along with the environment. The science models are made to protect the human body and the environment. Students learn about such concepts while working through these models.


3. Periscope:


A periscope is an instrument that is used to look at distant objects through a hidden position. Students make such working models and explain them to their peers. These models are used in submarines to see the surface above the water. A periscope is a flexible instrument that can be rotated in all directions. 


These are some other science projects for Class 7th students. Students can inculcate various skills while working through the process of making these models. The students can learn the practical application of the concepts learned while making such models. These are some of the best topics for class 7th science projects. Thus, these working models make certain concepts easy to understand.
