Homemade Sun Dryer - Practical assessment of sun dryer construction

By the end of the lesson, the learner should be able to:

- Demonstrate correct construction steps for a homemade sun dryer: frame assembly, fixing netting and covering with plastic
- Evaluate the completed sun dryer for stability, correct dimensions and readiness for use
- Show teamwork and precision during the practical sun dryer construction assessment

In groups, learners are guided to:
- Carry out the construction assessment: assemble the frame, fix mosquito netting shelves and cover with plastic sheeting
- Evaluate the completed sun dryer: check stability, netting tightness, plastic cover and overall dimensions
- Take pictures of the completed sun dryer and share experiences in the class plenary

How well can you construct a functional homemade sun dryer that meets the correct specifications for drying vegetables?

Homemade Sun Dryer - Practical assessment of sun drying vegetables

By the end of the lesson, the learner should be able to:

- Demonstrate correct technique in preparing and placing vegetables in the homemade sun dryer
- Evaluate the drying progress and explain how to determine when vegetables are adequately dried
- Show care and hygiene when handling fresh vegetables during the sun drying practical assessment

In groups, learners are guided to:
- Carry out the sun drying assessment: select fresh vegetables, wash, wipe, cut into small strips, spread in single layers on the drying rack
- Place the sun dryer in a sunny position and cover with plastic sheeting; return after a few hours to turn the vegetables
- Discuss how to determine when vegetables are dry enough and how to store them correctly after drying

How do we know when vegetables placed in a sun dryer are adequately dried and ready for storage?
