Activity Description:

Understanding of Crops in Soil in Soil - Our Life - Class 7 Science Experiment

In this activity, students will work in groups of four to five to gather information about the crops grown in a year in their village.

They will investigate the reasons behind crop rotation and the practice of growing certain crops repeatedly. Students will record their observations in their notebooks.

Required Items:

  • Notebooks
  • Pen/pencil
  • Access to agricultural information about local crops

Step by Step Procedure:

  1. Form groups of four to five students.
  2. Research and collect information about the crops that are grown in a year in their village. Take note of the specific crops grown and the sequence in which they are cultivated.
  3. Investigate the reasons behind the practice of crop rotation. Look for information about the benefits of rotating crops and its impact on soil health.
  4. Focus on pulses and find out why they are grown frequently in the crop rotation cycle.
  5. Explore if there are any crops that are grown continuously in the same field without rotation.

Experiment Observations:

  1. Note down the list of crops grown in the village and their order in the crop rotation cycle.
  2. Document the reasons behind the practice of crop rotation and its advantages for soil fertility.
  3. Identify the reasons for the frequent cultivation of pulses in the crop rotation cycle.
  4. Make note of any crops that are grown continuously without rotation and the possible consequences.

Precautions:

  1. Ensure that the information collected is from reliable and credible sources.
  2. If conducting field visits, take permission from concerned authorities and farmers.
  3. Record the observations accurately to avoid any misinformation.

Lesson Learnt from Experiment:

Through this activity, students will gain an understanding of the various crops grown in their village, the importance of crop rotation in maintaining soil health and fertility, and the specific reasons for growing certain crops like pulses frequently. They will also learn about the potential consequences of continuous cultivation of the same crop in a field.
