In this activity, learners use Styrofoam to collect organisms from a pond, estuary or marine environment and then examine what they have caught with a microscope.

In this activity (p.25 of PDF), learners investigate spores. Mushrooms produce millions of spores which are equivalent to the seeds of plants but without the massive food reserves.

In this optics activity, learners experiment with polarizers (small dark rectangles) to examine light intensity.

This investigation provides learners with a hands-on activity that simulates the changing relationship of surface areas-to-volume for a growing cell.

In this activity, learners will plot the distribution of various oozes using information from sediment maps.

This lesson introduces learners to the world of nematodes (roundworms).
