Engaging Kids in Environmental Issues using Open Science:
MboaLab as community Lab and makerspace always pays attention to the needs of local populations and strives to empower them with the tools they need to tackle their own problems. This vision is aligned with Public Lab efforts of democratizing science to address
environmental issues that affect people. It is under these circumstances that we have received
some equipment from the Public Lab, to investigate environmental issues related to our
The educational environment being a powerful vehicle for raising awareness and commitment
to climate issues; Mboalab, therefore decided to organize a workshop on 19 and 20
November, for some primary schools in the village of Mefou-Assi (Yaoundé, Cameroon).
During the workshop, students had the occasion to learn, mount and use: the Community
Microscope, Lego Spectrometer as well as the Papercraft Spectrometer.
Using Community Microscopes
The day I of the workshop was focused on microscopy, primary grade children and their
teachers were given basic notions on its use. Immediately after the very interactive course,
assembled in groups, participants started mounting their own community microscopes.
The interest that the community microscope arose in these students was so great that they
decided to take action by tackling the problem of water quality. Children took us on a tour
around their village and the water sources used to collect drinking water. Water samples from
the various sources were collected and we all rushed back to the Lab to analyse it using the
community microscope they built. We will never forget the astonishment on their faces when
they saw moving shapes in live inside the water they use to drink and use.
It might seem strange and odd for many people but access to safe and sufficient drinking
water under acceptable, assessable and affordable economic circumstances remains a major
problem in Africa and Cameroon is a good example.
Day two was more focused on spectrometry, we had to use more specific and tailor-made
examples to capture the attention of the children and explain the principles and application of
this relatively difficult to understand science. In the end, children were very receptive and
curious. Similarly to Day I, we started with a brief course and proceeded with having every
one mounting the Lego spectrometer. A competition was also organised to see which group
will finish first and a record of twenty minutes was observed.
We then went on, bringing out scissors, glue, CDs and sharing the paper craft photometer and the foldable mini spectrometer, after two hours of intensive practical session, fully functional DIY spectrometers were in the hands of the children. The plan was to use these to analyse drinking water from the various sources by using the spectral work bench website to capture the spectral graph of collected water and compare it to the one of mineral water.
In conclusion the “Public Lab workshop” organised in MboaLab was very fruitful one for everyone. Children had the occasion to use DIY tools to observe and investigate an issue that matters a lot to them. It also raised new insights and prospects for future work for the Public Lab, and from feedback we had from teacher participants and even parents, such events that trigger the creativity and involve local population are to be multiplied in the future.
