Science Education

Formerly known as European Learning Laboratory for the Life Sciences

Our inspiring educational experiences share the scientific discoveries of EMBL with young learners aged 10-19 years and teachers in Europe and beyond. We belong to EMBL’s Science Education and Public Engagement office.

Microscope in Action

‘Microscope in Action’ (MiA) brings fluorescence microscopy to schools. 

It is an educational microscopy kit designed to help educators inspire and fascinate students through active STEM learning. It is flexible, adaptable, and has curriculum links to physics and biology with connections to chemistry, technology as well as the arts. It can be used in formal and informal learning environments with students 14+. 

Learning goals

  1. Assemble the learning microscope and understand the concept of fluorescence microscopy
  2. Know applications of fluorescence microscopy in the natural sciences and beyond
  3. Understand the connection between research, technology and applied sciences
  4. Apply interdisciplinary and interconnected thinking
  5. Develop soft skills- teamwork and communication

Lease service: We offer a free-of-charge lease service of the educational microscopy kit for educators in Germany.

Coming up: The kits will be available for lease by educators outside of Germany. The fluorescence learning microscopes will also be available for purchase through EMBLEM Technology Transfer GmbH.

MiA kit


Microscope in Action (MiA) offers an engaging hands-on STEM learning experience by providing access to a research-grade instrument. It is built on the pedagogical approach of active learning and brings into focus the interdisciplinary nature of science by combining concepts from both physics and biology. The MiA design invokes inquiry-based active learning, collaborative work and helps students understand how technology and research go hand-in-hand. 

In MiA workshops, students build a fluorescence microscope from its basic optical, mechanical, and electronic parts. This allows students to get up-close with each individual component and through the process of active inquiry understand its function as they connect the different parts to build a fully functioning fluorescence microscope. The self-built microscope is then put into action through ready-to-use exercises for simple sample preparation, staining, imaging and image analysis. This facilitates the exploration of biological topics and helps the students develop interdisciplinary and interconnected thinking.

We offer regularly scheduled online introductory sessions for educators who want to learn more about this resource or wish to organise a workshop for their students. Further information can be found below.

Design principle
Modular- The modular structure provides flexibility allowing educators to design an MiA workshop to fit their classroom timetables with varying durations and subject linked learning goals.

Adaptable – Educators can easily adapt and customise the learning experience/goals for different learning environments, levels and to their teaching methodology and approaches.

Accessible – MiA provides varied topical access points and resources which stimulate and engage diverse learners and learning styles 

Curriculum links and more
It currently directly links to German and other national secondary school curricula in physics, biology, interdisciplinary natural sciences, and technology. It also offers complementary content for chemistry, bioinformatics and visual arts for ages 14–19+. The resource can also be adapted as a training tool for other training and educational levels- including bachelors, masters, scientists and teacher training courses.


  • Microscopy: alternatives to light microscopy, optics of a (fluorescence) microscope, preparation of biological samples
  • Biochemistry, Molecular and Cell Biology: working with a micropipette, preparing dilutions, autofluorescence, Green Fluorescent Protein, applications of fluorescence microscopy in biological research


  • Optics: collimation, magnification
  • Fluorescence


  • Luminescence/ fluorescence: differences between types of luminescence, energy states
  • Stains and chromophores

Computer science

  • Data and image analysis: using image analysis software such as ImageJ/Fiji

Natural sciences & technology studies

  • Linking natural science and technology

Impact on students learning  
Students who have taken part in MiA workshops show a good understanding of subject-related conceptual knowledge, marked improvement in practical and experimental skills, and development of interdisciplinary thinking and soft skills. Our assessments also indicate increased learning motivation, and high engagement and enjoyment towards the topics covered even among students with low science interest.

Lease service

You can lease, free of charge, the MiA kits for your classroom. The lease service is currently offered to German educators from secondary schools, Pädagogische Hochschule (universities of education) and out-of-school learning spaces. 

Coming up – Lease service will be expanded to make the kits available to educators outside of Germany. 

Rental period: 2-6 weeks 

Overview of a standard lease package 

  • Fluorescence Learning microscope (research-grade) – maximum 6 microscopes
  • Access to the learning and teaching materials 
  • Training session – regularly scheduled

Optionally you can include in your lease:

  • Laptops- Maximum 6 laptops
  • Experimental kit with materials for sample preparation – Enough for maximum of 24 participants

A lease package with 6 microscopes is sufficient to organise an MiA learning experience with up to 24 participants. Here you can download further information about the kit – MiA educational kit.

Lease process

  1. We recommend starting the lease process as soon as possible, at least 8-12 weeks before you wish to use the kits. It is not possible to accommodate last minute requests, especially if you are a first time lessee.
  1. Complete the lease application form and read the summary of the lease agreement (found below) to make sure you are able to adhere to all necessary rules. You can contact us if you have any questions or concerns about this agreement.
  1. EMBL will share confirmation of your application along with the lease agreement. You will have a few weeks to go over the agreement in detail and return it to us signed (a digitally signed or scanned copy is accepted)
  1. Attend a Training session: For 1st time lessees’ it is compulsory to attend a training session before you can start working with the equipment. This session can happen before or after you collect the equipment.
  1. You arrange and assume the cost and responsibility for pick up and return of the equipment- By car or transport company 

Lease application form
To start the lease process please complete the application form which are available in German or English.
