When van Leeuwenhoek saw cells and single-celled organisms for the first time, he knew these small things were a big deal! Share his discoveries with young learners through a narrated video, model-building activity, and scale study....

In this activity, students will collect data by measuring different linear objects and develop a strategy to determine the conversion factors required to convert from one linear measurement to another.
