In this quick activity about predicting (located on page 2 of the PDF), learners working alone or in groups will use toothpicks to probe a clay ball with a small object hidden in its center and then predict what's inside. Learners will share their predictions and how they came to these conclusions before opening the ball to see what is inside. This exercise illustrates how nanoscientists can still make discoveries studying things too small to see, using special probes to "feel" bumps at the atomic level. Also relates to linked video, DragonflyTV Nano: Where's Nano?
