Why Lesson Planet?
Here's a five-star lesson plan in which inquisitors conduct sophisticated experimentation with cellular respiration in plant seeds. Placing seeds in a closed system they measure the amount carbon dioxide produced and relate it to respiration rates, varying either the moisture, temperature, or amount of light. Thorough background information and teachers' notes are provided, but the mentioned lab sheet is not. If your biologists, ecologists, or botanists are able to perform this inquiry, then they can also write their own lab reports.
