Video: The Greenhouse Effect

Introduction

Greenhouses allow gardeners to grow plants in cold weather. This is because a greenhouse stays warmer than the outside air. You can feel this effect in a car parked in the sun. On a larger scale, the greenhouse effect helps keep our planet warm. It makes Venus one of the hottest planets in our solar system. In this experiment, you will use Temperature Probes to measure temperatures in a model greenhouse and in a control as they are heated. You will then calculate the resulting temperature changes.

Objectives

In this experiment, you will

  • Measure temperatures as a model greenhouse and a control are heated.
  • Determine the temperature changes for the two containers.
  • Use the results to make conclusions about the greenhouse effect.
