Chemistry Exhibition Project ideas for class 7

CBSE CLASS 7 Published on 28 January 2022

Chemistry is a broad field of science including substances, matter, actions, reactions, properties of ions, anions and much more. It is considered a difficult subject including practical applications and projects. There are some best chemistry projects which are made by the students that can be represented at the inter-school or inter–state level. Working on these projects, students inculcate various skills like teamwork, leadership skills and much more. 


In the chemistry exhibition, students can explain these projects to the teachers and their peers. While explaining the projects, various concepts are cleared that might be difficult to understand in the classroom lectures. Below is the list of some chemistry projects that students make to represent them at the exhibition.

  5. Instant Terrariums
  6. How to make paper
  7. Dry Erase Drawing
  8. Recycled Plastic Flowers


7. Crystal Projects:


Crystals are materials that are formed by the repetition of molecules. There are four types of molecules i.e. covalent molecules, molecular molecules, metallic molecules and ionic molecules.


  1. Classic Borax Crystals
  2. Overnight Crystal Garden
  3. Egg Geodes
  4. Crystal Wind Catchers
  5. Crystal Landscapes
  6. Candy Geodes 
  7. Salt Crystals


These are some of the innovative chemistry projects that students will love to make. You can also consider them as chemistry science fair projects for 10th grade. Rather these projects can be made by students of any class. Students can learn from these projects, thereby clearing several doubts.  


College Chemistry Projects


In college or university, projects are a part of the curriculum. Students opting for medical or non–medical are evaluated on the basis of the models and projects they make. These projects, if selected, are showcased in various science or chemistry exhibitions organized by the college. Below is the list of some of the chemistry projects for college students.


  1. A comparison of solubility of carbon dioxide in water at various temperatures
  2. A penny’s worth of Hydrogen
  3. A study of saponification reactions
  4. Activities of Metals
