Science Cases

Expand your knowledge of the Universe from your school

The CESAR team provides free online interactive tools and material to introduce students in the field of astronomy, science and technology by doing what we call, a Science Case. In some of the Science Cases, students will be required to use the CESAR observatories, which means, they will have to follow all scientific method for the very beginning. The scientific cases are not only to make science approachable for young people but also to help them develop their critical thinking.

Choose the correct Science Case

Depending on student's age and their knowledge of mathematics and physics, the Science Cases are divided into three difficuly levels: high, medium and low. Teachers can then choose the best Science Cases for their students. Not all the Science Cases are developed for all levels, but most of them are. Please read the complete guide of how to perform a Science Case with your students available here.


Prepare for a Science Case

Most of the Science Cases already have all the documentation to be able to complete them in 30-60 minutes. Some others will also require to contact CESAR team to use the obvervatories for taking necessary images of the Sun, Solar Sistem planets, and many more.
For each Science Case, we provide:
  1. A teacher's guide: a guide where teachers find the key information they must provide to their students in order to perform their Science Case   
  2. A student's guide: a manual for students working on their Science Case  
  3. Calculation guide: a sheet with the formulas required by the students to perform their calculations
  4. Calculations and results: a sheet where the students will write their calculations
  5. Student quiz: a set of questions that should be answered by the students to check whether the concepts studied have been assimilated
  6. Additional information:  Links to interesting pages or videos related to the topic


Together with the Science Cases, CESAR also provides with several booklets which can help students to get a better background and a better understanding of different topics.
