On National Scientists’ Day and in honor of Professor Mariano Gago, we celebrated the end of another school year bringing microbiology to elementary schools through the project “Today, I Am the Bioscientist.” This time, we worked as scientists with about 180 third- and fourth-grade students, divided into six classes. They learned what microbes, bacteria, and fungi are; what cells can do with their complex structure; why living beings are so different; the mysteries of DNA and its hidden message; the chromosomes of boys and girls and genetic diversity; antibiotics and why we must protect them—and so much more that can’t fit into a single post. Microscopes, pipettes, and Petri dishes went to the schools, and the children came to the Microbiology labs of the Department of Bioengineering at the Instituto Superior Técnico to meet real-life scientists. Let’s hope they’ve learned a little about the magic (though sometimes difficult) that lies behind science. And we’ve learned how to explain complex concepts in simple terms, how to answer a thousand questions (sometimes all at once) for which we weren’t prepared, and that being a child means having immense creativity and a freedom to ask questions that’s hard to replicate in other stages of life. To the young scientists, thank you very much—to those from São Bento Elementary School (part of the Carnaxide School District) and those from São João de Deus School (part of the D. Filipa Lencastre School District). This project had the strong support of the Department of Bioengineering and of the Biological Sciences Research Group.
