Description from the website

Gather clues - Interview suspects - Analyze evidence
Solve a mysterious death
This activity is set in a research group that is developing an antivenom for spider bites. In the opening scene, Nelson Pogline, a talented graduate student, dies unexpectedly at a university reception. As a detective, you must use chemistry concepts to determine if this was murder and if so, solve the case. You can interview suspects using Quicktime movies, investigate the crime scene for clues with Quicktime Virtual Reality images, and analyze the evidence from the crime lab.

How Stuff Works NPK Soils

Nitrogen (N): Helps make chlorophyll that gives deep green color. Chlorophyll is necessary for photosynthesis, the essential process in which plants manufacture carbohydrates (their stored energy source) from water, carbon dioxide and sunlight.

Phosphorus (P): Promotes strong root development and winter hardiness. It helps withstand environmental stress. Plants supplied with phosphorus is less likely to become diseased.

Potassium (K): Reduces transpiration (loss of water through leaves), so plants need less water when it has enough potassium. It strengthens leave and helps withstand stress.
