Make teaching diffusion easy. Exclusively from Ward's Science, we've pre-mixed, pre-poured, pre-measured and pre-cut these agar cubes to save you time and eliminate messy preparation in your lab. Just open the jar and begin using. Prepared to align with Ward's AP Biology Investigation 4: Diffusion and Osmosis, these cubes are also ideal for use on their own, or in any lab activity demonstrating the topic of diffusion. Agar cubes are prepared in three sizes (approximately 1cm, 2cm, and 3 cm). Phenolphthalein has been added to the cubes to exhibit a vivid fuchsia color during production and stored in a solution of sodium hydroxide. Just add an acid such as vinegar to demonstrate diffusion.

Thermometers are ideal for round-the-clock monitoring of semi-solids, air/gas, or liquids in incubators, refrigerators, freezers, water baths, and outdoor tanks.

Participate in an authentic investigation on the genetics of sleep and circadian clocks.

These half size torsos are a great starter torso for any classroom. Available in three different part counts all of these models show basic human anatomy and systems. The most basic figures illustrate general structure of organs and systems and are cast with a cutaway skull exposing a cast brain. The Dissectible head version also shows more advanced head and neck structure, as well as a half brain removable from inside the skull. The most advanced version shows all of the same items as the dissectible head version and also includes a removable female insert, and shows musculature on the left side.
