In this math lesson, learners record and graph plant growth and interpret data. Learners plant seeds, and once the seeds sprout, record the change in height of the plants for several days.

In this activity, learners explore how the application of nano-sized particles or coatings can change a bigger material’s properties.

In this combination chemistry and physics activity, learners explore water absorption in dried beans or peas and learn how this affects their physical properties.

In this activity related to microbes, learners make slides of cells from an onion skin and Elodea (American or Canadian waterweed) to observe under a microscope.

In this outdoor biology and math activity, learners estimate the size of a population of organisms too numerous to count.

This is an activity (located on page 3 of PDF under Nasturtium Leaves Activity) about surface tension.

In this fun sticker activity, learners will create a size wheel with images of objects of different size, from macroscopic scale (like an ant) to nanoscale (like DNA).
