Investigating Soil Moisture: Understanding Soil Properties

Investigating Soil Moisture: Understanding Soil Properties

Overview

• 6th Grade

• Earth Science

• Soil Moisture

Learning Objectives

• Understand how soil moisture content affects plant growth.

• Measure and analyze soil moisture level and pH.

• Observe the relationship between soil properties and environmental conditions.

Materials Needed

• Digital soil moisture meter

• pH meter

• Thermometer

• Light meter

• Various soil samples (dry, wet, sandy, clayey)

• Plants for comparison (optional)

Safety Precautions

• Wear safety goggles if using any chemicals, though this is a low-risk lab.

• Keep the work area clean and organized.

• Handle all tools carefully and follow instructions for using meters.

Procedures

• Collect several different soil samples from various locations (e.g., garden, park, dry areas, wet areas).

• Measure and record the moisture content of the soil using the digital soil moisture meter. Follow the manufacturer's instructions for proper use of the equipment.

• Measure and record the pH level of each type of soil using the pH meter.

• Use the thermometer to record the temperature of each soil sample.

• Measure and record the light intensity at each location with the light meter (optional).

• Compare and analyze the results of different soil types and their moisture levels.

Observations

• Record the moisture content and pH levels of each soil sample.

• Note any physical characteristics of the soil samples such as color, texture, and composition.

Questions

• How does the soil moisture vary among different types of soil?

• What pH levels were found in different soil samples?

• How does the weather (e.g., rain, sun) relate to soil moisture and pH?

• What conclusions can you draw about the health of soil based on moisture and pH levels?

Notes: This lab explores the physical properties of soil and how different factors influence them, particularly focusing on soil moisture content and pH levels.
