"Realistically detailed soft foam cross-section. Teach the parts of a plant cell; One half of the cross-section is labeled with the parts of the cell, while the other half features only letters next to each cell part for assessment. Includes activity guide with information about each labeled part" --Amazon.

"Cross-sectioned model of an animal. The soft foam cell splits in half to show the key parts of an animal cell, including the nucleus, nucleolus, vacuole, centriole, cell membrane and more. One hemisphere is labeled with the parts of the cell; the other features only letters next to each cell part. A reference guide is included, providing activity ideas and facts about animal cells"

Help students learn about the anatomy of a plant cell with this 4D puzzle.

"The Slinky Spring with three times the normal length is ideal for demonstrating several fundamentals of wave motion. When the spring is extended, a lateral or longitudinal pulse can be observed in detail as it travels at the slower rate corresponding to low tension. By comparison, the longer and heavier helical spring demonstrates the effects of greater mass and of greater tension. Another interesting experiment is to join the two springs in line, stretch them, and observe the behaviour of a pulse from either end as it travels through the joint." --Spectrum website

"This apparatus allows students to investigate the elastic properties of a gas enclosed in a calibrated airtight syringe by subjecting the confined gas to various loads. The syringe is built into a sturdy wood base. The wooden top is large enough to support arbitrary uniform weights such as books or bricks. A plot of pressure versus volume of gas gives a good approximation of Boyle{u2019}s Law." --Spectrum's website.
