Water Cycle Column Investigations

Figure from experiment 17 from Investigating Environmental Science through Inquiry

Introduction

In this experiment, you will use a Water Cycle Column and probeware as you investigate the hydrologic cycle and related concepts.

In a typical three-bottle Water Cycle Column, water moves up a wick from a pool of water in the bottom chamber to soil in the middle chamber by capillary action. Water in the soil can evaporate and become water vapor in the middle chamber. Transpiration, the loss of water vapor from the aerial surfaces of plants, is an additional source of water vapor in the middle chamber.

Objectives

In the Preliminary Activity, you will gain experience using a pH Sensor and learn pH measuring technique as you determine the pH of a water sample.

After completing the Preliminary Activity, you will first use reference sources to find out more about the hydrologic cycle and related concepts before you choose and investigate a researchable question.

Sensors and Equipment

This investigation features the following Vernier sensors and equipment.

Additional Requirements

You may also need an interface and software for data collection. What do I need for data collection?
