This is an inquiry design lab for students to understand transpirational pull of plants. Like all inquiry labs, it is open for more designs than the one presented in the PowerPoint example. The example in the PowerPoint is the easiest to implement in the classroom. It requires a growlite (a bulb that produces the UV light plants need to grow), a fan, a light source with a 100 Watt bulb, Ziplock bags, rope, and plants that are the same (I use petunias).
