We present a didactic transposition in order to fill the gap between scientific outreach and the
technical part of a specific topic in Modern and Contemporary Physics (MCP). We use some
guidelines from Problem Based Learning in Didactic Transposition. The topic chosen was Bell’s
theorem. First, we talk about an important prerequisite for the theorem, which is entanglement,
a quantum property of extreme importance for quantum computation and for teleportation,
for example. Entanglement was presented at a level of scientific outreach and with its formal
definition as well. We then state, discuss, and prove Bell’s theorem. The demonstration was made
from graphical representations of the probabilities involved. In addition to the dissertation, we
produced an educational product entitled "Guidelines for the study of Modern and Contemporary
Physics", which serves as a pedagogical support for teaching MCP in any high school grade and
is available on the internet under the Creative Commons license. The product is divided into
three parts, one dedicated to the teacher, another containing a script for the student and, finally, a
resolution algorithm related to the quantum entanglement of particles. To analyze the results of
its application, qualitative aspects were taken into account in the evaluation of the work produced
by the students, as well as the quantitative analysis in the resolution of the algorithm. We use
an online questionnaire to analyze the data regarding the application of the educational product.
We believe this work can contribute significantly to the dissemination of scientific knowledge in
basic education, providing a complement in the training of students in order to raise scientific
curiosity in them, seeing in Physics a possibility for their professional career
