ABOUT THE SCIENCE FAIR LOGO

The original Falmouth Academy Science Fair logo was a linoleum cut designed by Ira Carmel ’89 on the occasion of FA’s inaugural science fair, held on March 17, 1989. The logo was refreshed in celebration of the 30th anniversary of the Fair, but retains its original whimsical representation of the depth and breadth of the research that is conducted by our students. Whether exploring the basic elements of life or building better rockets, our students’ curiosity about the world around them is reflected in this logo and in all the work presented.

During the months and days leading up to our Science and Engineering Fair, there are many teachable moments and opportunities for students to explore, discover, and question. With 24/7 news, sometimes inaccurate or polarizing information, a global pandemic, and the trend to question scientific fact, it is ever-more important for students to be able to differentiate truth from fiction.

Students often ask their science teachers, “Is this true or is it propaganda?” “Should I believe what I’m hearing on the news?” “Is this source reliable?” I appreciate that our students understand that there are choices to be made, and that they want to make an educated one.

All this questioning leads students toward the topic they choose for their Science and Engineering Fair project. Throughout their experimentation, they learn to trust the scientific method to arrive at their results. These are wonderful teaching moments, and I often tell them, “The cure to cancer will most likely, initially be considered a mistake.”

They grow to embrace their mistakes and to see what they can learn from them. It’s an absolute joy to participate in these conversations, and when that “Aha” moment is seen marching across their faces, I can’t help but smile from ear to ear.

Thank you for your amazing support of our students through this process of discovery.
