KIT:Glass-topped display illustrates the life cycle of pines. Using dried, labeled specimens, this case features a pine seedling, mature needle, male cone, spring (young) and fall (mature) female cones, and a pine seed showing the characteristic wing to aid in dispersal.

KIT:This display depicts the mechanisms plants use to expand their range, including by wind dispersal, attachment to animals, transportation by water, and scattering by birds.

KIT:Investigate leaf structure with this model of a lima bean leaf. It is a 45x model with detail of the transverse and longitudinal sections. The mesophyll includes palisade and spongy parenchyma. Both surfaces are shown with stomas and guard cells. There is additional detail of the xylem, phloem, and vascular veins. Constructed of durable plastic.

Demonstrate and observe the process of osmosis betwwen hypotonic and hypertonic solutions separated by a semipermeable membrane. Study the effects of solute concentration, temperature, and pH on osmosis. Predict the characteristics of substances that allow them to pass through a semipermeable membrane. Explain the causes and effects of water movement in living cells

This book about the tree-killing Asian longhorned beetle reveals how the help of everyday people, their neighborhoods, teams of beetle-sniffing dogs, and a nationwide effort from bug scientists to tree doctors are working to eradicate this invasive pest.

The Nonfiction Detectives: Beetle Busters by Loree Griffin Burns. Burns explains that the idea to write this book came after Asian longhorned beetles were found in her small town in Massachusetts.

Soil is more than dirt-it's the stuff of life. It supports, directly or indirectly, every creature that lives on land, Homo sapiens included. As such, the fertile, nutrient-rich topsoils capable of growing our crops are an central natural resource. But soil, the backbone of agriculture and civilization for 10, 000 years, is danger of slipping through our fingers. Every year we lose millions of acres of it to erosion, nutrient depletion, and ruination from salt and sprawling human…
