Experiments With Roots
Gravitropism: Kids will learn how plants use gravitropism to sense gravity.

Cuttings: In this lesson, students will learn how to create cuttings off a parent plant to propagate new plants.

Ground Layering: Layering is a way to get stems to root while they are still attached to the parent plant. The technique of simple layering involves bending a low-growing stem to ground level and burying a few inches of the stem behind the tip. The piece actually buried must be roughened, nicked or slit and preferably bent up at as near a right angle as possible and secured to a stake.
To air layer, you shallowly wound a stem a few inches below the tip to stimulate root production, and then wrap moist sphagnum moss around the stem |
