This plant cell model shows the structure of a typical plant cell. It contains 25 molded organelles including nucleic membranes, double-spiral chromosomes, endoplasmic reticulum, cross-sectioned chloroplast with grana and grana discs, large central vacuole, mitochondria, and ribosomes. The cell wall is clearly divided into middle lamella, primary wall, 3 secondary walls, warted tertiary wall, and plasma membrane.

This animal cell model shows the structure of a typical animal cell. Significant structures within the cell are shown in raised relief, but cannot be removed from the cell model. These structures include the nucleus, basal membrane, collagen fibers, mitochondria, lysosomes, Golgi apparatus, microvilli, and the smooth and rough endoplasmic reticulum.

Owl pellets are masses of undigested parts of food that owl species occasionally regurgitate. The contents of the owl pellet depends on its diet, but can include the exoskeletons of insects, indigestible plant matter, bones, fur, feathers, bills, claws, and teeth.

Examine and compare specimens from the most diverse group of animals on our planet—the insects. This display features a preserved and mounted representative from each of the 9 major insect orders: Orthoptera, Hymenoptera, Ephemerida, Diptera, Lepidoptera, Coleoptera, Hemiptera, Odonata, and Isoptera. 

This Riker mount shows students the characteristics of insect metamorphosis. Gradual metamorphosis is demonstrated by the grasshopper, incomplete metamorphosis by the cicada, and complete metamorphosis by the butterfly.

This poster shows the complete metamorphosis of a Monarch butterfly.

With this collection, students can learn to identify insects that are beneficial to our natural ecosystem. The 10 specimens in the collection are individually embedded in plastic blocks. Includes silkworm, dragonfly, dung beetle, praying mantis, honey bee, ladybug, diving beetle, tiger beetle, giant hornet, and heath tiger beetle.

This collection helps your students learn to identify 10 insects that have a harmful impact on human life. The collection's 10 specimens are individually embedded in plastic blocks. Includes cockroach, weevil, grasshopper, antler horned beetle, longhorn beetle, stag beetle, mole cricket, flower beetle, onion fly, and shield beetle.

These jars have ladybug wings that open reveal a 3.5x magnifying lens. Encourage students to describe or write about the bugs they catch. The screw-on cap and air vents keep specimens secure.

This collection consists of 30 fossils representing animal phyla and plants from the Cambrian to the Cretaceous Periods. Specimens are number coded with a key.

The 15 fossils in this group illustrate the major types of fossilization: petrification (substitution of a mineral, often silica), pyritization (substitution of iron sulfide), molds and casts (impressions filled with minerals), and distillation or carbonization (a carbon film or layer represents the remains of the original organism).

This dissecting kit includes: 1 dissecting scissors, 1 dissecting forceps, 1 surgeon’s scalpel, 1 plastic handle teasing needle (straight), 1 plastic handle teasing needle (curved), 1 dropping pipet, 1 6-in transparent vinyl ruler, and 6 dissecting "T" pins.  All equipment is student grade.
