This is an activity (located on page 3 of PDF under Nasturtium Leaves Activity) about surface tension. Learners will test different leaves with drops of water and full submersion to compare how water interacts with the leaf surface. Water will stick to some leaves more than others, seeming to almost jump off some. Learners record their observations in a table and produce leaf drawings/rubbings. This activity introduces learners to forces on the nanoscale and relates to linked video, DragonflyTV Nano: Nasturtium Leaves.
