In this lab you will be investigating the effects of different environmental factors on the rate of transpiration in a plant. You will be using a. potometer. (a pipette attached to a rubber tube) to measure the rate of water loss in a plant.n this lab you will be investigating the effects of different environmental factors on the rate of transpiration in a plant.

The carâs radiator acts as a heat exchanger, transferring excess heat from the engineâs coolant fluid into the air. The radiator is composed of tubes that carry the coolant fluid, a protective cap thatâs actually a pressure valve and a tank on each side to catch the coolant fluid overflow.
Here's how to do it: Pay attention to the icon on your car's dashboard that indicates if the engine is overheating or if you're car's low on coolant. If the light comes on and stays on, it means you're low on engine coolant [source: pontiac]. A car radiator cannot work if there isn't enough coolant inside the system.
