How Does Folic Acid Prevent Neural Tube Defects?

Introduce a variety of basic scientific concepts and properties.

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.

Students perform thin-layer chromatographic separation of carotene, xanthophyll, and chlorophylls.

Measure water uptake from the processes of photosynthesis and transpiration.

In this experiment, students safely analyze the enzymatic decomposition of hydrogen peroxide.

Learn about vaccine development and clinical trials with this innovative classroom lab activity.

How do you test urine?

Perfect for a student team.

Students learn how to use a micro hematocrit to determine percent of solids in blood using simulated blood.

The selective permeability of membranes is of fundamental importance to cellular physiology. Students will perform experimental procedures involving diffusion, dialysis, water potential and osmotic potential. For 10 lab groups.

This kit identifies five classes of nutrients.
