• Small shovel or trowel
• Plastic ziplock bags
• Water
• Paper and pencil for notes

No prior knowledge or preparation is required for this lesson.

Activities

1. Activity 1: Soil Observation

   Go outside to a garden or a nearby park. Use the small shovel or trowel to collect a sample of soil from the ground. Place the soil in the glass jar. Observe the color, texture, and any visible particles or organisms in the soil. Take notes on your observations.

2. Activity 2: Soil Separation

   Back at home, pour some water into the glass jar with the soil. Close the jar tightly and shake it vigorously for a few minutes. Let the jar sit undisturbed for a while. Observe the layers that form in the jar. Take notes on your observations.

3. Activity 3: Soil Composition

   Take a small amount of soil from each layer in the jar and place it in separate ziplock bags. Label each bag with the corresponding layer. Examine the soil samples and describe their differences in color, texture, and composition. Take notes on your observations.
