The aim of the article is to show how to encourage
students to deepen their knowledge and their enthusiasm for research. In this
way we can also promote the popularization of science and technology as well as
the identification of students talented in specific research areas.This article
presents an example of writing a research assignment undertaken by students in
the final year of primary school (class 9, i.e. age 14-15). During school
lessons, we did not discuss biomass as fuel in detail, but we found the topic
very interesting, which is why we decided theat we would focus on it in our
research paper. We live in the age of diminishing supplies of fossil fuels and
consequently a growing interest in the renewable energy sources, including
biofuels.Through research assignment, we wanted our students to learn more
about the characteristics of biofuels which we haven’t discussed in detail in
class. Biofuel is a solid, liquid or gaseous fuel, obtained from a relatively
recently deceased biological substance. In addition to looking for information
in literature and electronic resources, we conducted experiments in which we
measured how many degrees a particular quantity of water heats up by the
burning of various fuels, and the amount of residue left after burning. The
fuels we used were: pellets, briquettes, olive pomace, cherry stones,
biodiesel, ethanol and sawdust.We established that different types of fuel
emit, when burnt, different amounts of heat. Water heated up the most when burning ethanol,
while it heated up the least when using biodiesel. Experiments showed that
different fuels burn for different amounts of time, leaving a residue which
depends on the type of fuel.
