Ward's® Prepared Agar Cubes

Avg. Ratings: 5.0 (5 Reviews)
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. Jar contains six each of the three sizes.

Ordering information: At times, supply may be limited due to high demand.  Please place your order approximately two weeks in advance.

I love these agar cubes! They are super easy for students to use to design a diffusion experiment and can be stored for a long time. I have made my own but the time savings and bright color for the basic solution makes these a really good value for me as a teacher.

These cubes are a huge time saver! I love how they are made and how useful they are for instruction. The students love to use them and how they really demonstrate the importance of cell size and diffusion rates.

I first learned about these fully prepared agar cubes at an AP Summer Institute. I was skeptical at first as our school had been used to making and preparing our own agar cubes, but the school year can quickly become inundated with distractions as the year progresses. These agar cubes come in nice jars and have a good shelf life if stored at 4 C. We now use them every year for all biology classes, from College-prep to Honors and AP and they've quickly become a student favorite!
